Abstract: Jiaohe City stands as one of the principal production areas of high - quality Ganoderma lucidum and sporoderm - broken G. lucidum spore powder in China. Situated in the transitional region from the Changbai Mountains to the Songliao Plain, it is mainly characterized by low mountains and hills. It features a temperate continental monsoon climate, with an annual average temperature of 4.38 ºC and an average annual precipitation of 710 mm. The soil predominantly consists of black soil, which is rich in nutrients, and the heavy metal contents are below the national standard limits (GB 15618-2018 and HJ/T332-2006). The water environmental quality meets the Standards for Drinking Water Quality (GB 5749-2022), rendering it suitable for G. lucidum irrigation. Jiaohe G. lucidum is cultivated using Xylosma congestum wood segments as the substrate. The wood is dense and contains abundant nutrient elements, which can provide sufficient nutrients for mycelial growth and meet the requirements of fruiting body development. The total triterpenoid and polysaccharide contents in G. lucidum slices exceed the limits stipulated in the 2020 edition of the Pharmacopoeia of the People's Republic of China, and 11 pesticides, including deltamethrin, are not detected. The average sporoderm - broken rate of the spore powder is 99.2%. The average contents of total triterpenoids are 9.16 g/100g and those of polysaccharides are 2.47 g/100g, all surpassing the limits set by the group standard Ganoderma lucidum Spore Powder from Changbai Mountain in Jilin (T/YYTC 008 - 2024). Meanwhile, the ash content, peroxide value, heavy metal contents, and microbial counts comply with the standard limits, and pesticides such as BHC and DDT, as well as pathogenic bacteria like Salmonella and Staphylococcus aureus, are not detected. Jiaohe City has a long - standing history of G. lucidum cultivation and has established a comprehensive industrial chain production model. This model encompasses spawn cultivation, technical guidance, corporate buy - back, and deep processing into high - value - added products. It has evolved from the traditional model of extensive production and low - price sales to new business formats, including e - commerce live streaming and culture - tourism integration.

1. Introduction
In the context of the rapid development of the social economy and the continuous improvement of living standards, the public's demand for daily health preservation and wellness is on the rise. The "Quality Geographic Products" initiative, featuring agricultural modernization and intelligent agricultural monitoring and management, has emerged in line with this trend[1 - 2]. Since 2016, the Chinese government has promulgated policies such as the "Healthy China 2030" Planning Outline, the National Nutrition Plan (2017 - 2030), and the "14th Five - Year Plan" for National Health to foster public health awareness and a prevention - oriented health concept, thereby implementing the Healthy China strategy. Especially after the COVID-19 pandemic, enhancing immunity has become a core requirement for people of all age groups to maintain bodily functions. Anti - aging and antioxidant properties, regulation of blood glucose, lipids, and blood pressure, as well as liver protection and detoxification, represent major consumption trends among the young, middle - aged, and elderly populations for specialty agricultural products and health foods.
Ganoderma lucidum refers to the dried fruiting body of the Polyporaceae fungi Ganoderma lucidum (Leyss. ex Fr.) Karst. or Ganoderma sinense Zhao, Xu et Zhang[3]. Presently, a total of 137 species within the genus Ganoderma have been identified globally, among which the confirmed species in China constitute 88% of the overall count[4]. Research findings suggest that polysaccharides, triterpenoids, sterols, small peptides, adenosine, and alkaloids are the principal active constituents of G. lucidum, which demonstrate effects such as immune enhancement, anti - inflammatory and antioxidant activities, anti - tumor properties, neuroprotection, as well as anti - glycemic and hepatoprotective effects[5-6]. The Pharmacopoeia of the People’s Republic of China (2000 edition)[3] has documented the medicinal value of G. lucidum. In 2001, the Ministry of Health incorporated G. lucidum (including G. lucidum and G. sinense) and G. tsugae into the "List of Fungal Strains Usable for Health Foods". In 2019, G. lucidum was included in the List of Medicinal and Edible Substances by the National Health Commission. In 2021 and 2023, the State Administration for Market Regulation, the National Health Commission, and the National Administration of Traditional Chinese Medicine successively issued the Directory of Health Food Ingredients: Sporoderm - broken G. lucidum Spore Powder and the Directory of Health Food Ingredients: G. lucidum. As the origin of G. lucidum, China holds a leading position globally in terms of both production volume and quality. Statistics from the China Edible Fungi Association indicated that in 2023, the total output of G. lucidum in China reached 159,800 tons, with G. lucidum accounting for over 50%, and the total national consumption amounted to 50,000 tons[7]. According to data from the General Administration of Customs, China's exports of G. lucidum products reached 5,000 tons, with a value of 100 million USD in 2023, representing year - on - year increases of 10% and 15% respectively[7]. The "14th Five - Year Plan" for National Agricultural Modernization explicitly advocates for the support of the G. lucidum industry, and the National Report on the Development of Characteristic Rural Industries also designates G. lucidum as a key support sector.
The production areas of Ganoderma lucidum in China are primarily concentrated in regions such as the Changbai Mountains in Jilin, Mount Tai and Guanxian in Shandong, the Dabie Mountains in Anhui, and Huangsongdian in Jilin. The quality of Ganoderma lucidum varies owing to differences in varieties, ecological environments, and cultivation techniques. The Huangsongdian production area in Jilin Province is part of Jiaohe City, situated at the western foot of the Changbai Mountains and beside Songhua Lake, within the transitional zone from the Changbai Mountains to the Songliao Plain, which is known as a "Three - dimensional Resource Treasure Trove of the Changbai Mountains." In Jiaohe City, Ganoderma lucidum is cultivated using the locally prevalent Xylosma congestum wood as a substrate, recognized as the "golden substrate" for Ganoderma lucidum or the preferred material for "semi - wild" cultivation, giving rise to high - quality geographical specialty products represented by "Huangsongdian Ganoderma lucidum." To facilitate the orderly development of the "Case Studies on the Protection of Quality Geographic Environment and Sustainable Development" initiative[8], this paper developed and analyzed the dataset of the Jiaohe Ganoderma lucidum geo - ecological environment case study in the Changbai Mountain area, with the aim of providing scientific and technological support for the geo - ecological protection and sustainable development of Jiaohe Ganoderma lucidum.

3. Overview of the Case Study Area
Jiaohe City (126º45′–127º56′E, 43º12′–44º09′N) is situated at the western foot of the Changbai Mountains, at the southern terminus of the Zhangguangcai Range, and on the shore of Songhua Lake. It shares boundaries with Dunhua City of Yanbian Korean Autonomous Prefecture to the east, separated by the Weihu Ridge, Huadian City to the south, the Longtan and Fengman Districts of Jilin City to the west, and Shulan City and Wuchang City of Heilongjiang Province to the north (Figure 1). The topography is characterized by higher elevations in the northeast and lower elevations in the southwest, with an average altitude of 455 m.
Jiaohe City falls within the Songhua River system, boasting 89 rivers [1]. The majority of these rivers flow from north to south or east to west, ultimately discharging into Songhua Lake. The river surface area is approximately 231.87 km², and the water area of Songhua Lake spans 330 km². The principal rivers include the Lafa River, with a total length of 65 km and a drainage area of 920 km², and the Gaya River, with a total length of 75 km and a drainage area of 1,121 km², along with the Jiaohe, Mangniu, and Piaohe rivers, as well as the Hongxing, Longfeng, and Qingfeng reservoirs. The total surface water resources of the city amount to 1.752 billion m³, and the exploitable groundwater resources reach 5.103 billion m³.
The cultivation of Ganoderma lucidum in Jiaohe City is predominantly concentrated in Huangsongdian Town, Xinzhan Town, Qianjin Township, Lafa Sub - district, Henan Sub - district, Wulin Korean Township, and Baishishan Town. These areas were chosen as the case - study area. The total area amounts to 3,041 km², incorporating 140 administrative villages and 6 communities (Figure 1).

4. Eco-environmental Data
4.1 Topography and Geomorphology
The case study area is characterized by a topography that is elevated in the east and lower in the west, with a central low - lying area encircled by higher terrains, exhibiting a composite landscape of hills, mountains, and valleys. An analysis grounded in Digital Elevation Model (DEM) data[2] revealed that the altitude spans from 248 to 1,283 m, with a mean altitude of 488 m (Figure 2). The slopes vary from 0 to 45.4º, with an average slope of 8.4º (Figure 3). The moderate altitude and gentle slopes, in conjunction with a suitable climate and adequate drainage conditions, are conducive to greenhouse construction, production management, and harvesting operations.

4.2 Climatic Characteristics
The case - study area features a temperate continental monsoon climate, which is characterized by the co - occurrence of rainfall and heat and distinct four seasons. A statistical analysis of meteorological data from 1980 to 2024[3] reveals that the multi - year averages of the maximum, minimum, and mean temperatures were 10.68 ºC, - 1.17 ºC, and 4.38 ºC, respectively. The annual precipitation ranged from 455.0 to 1,033.2 mm, with a multi - year average precipitation of 710.8 mm (Figure 4). Temperature and precipitation exhibit significant seasonal differentiation. In summer (June - August), rainfall accounts for 62.7% of the annual precipitation, amounting to 455.7 mm. The highest temperature (27.16 ºC) and maximum precipitation (178.9 mm) occur in July, with a daily mean precipitation of 5.77 mm and a daily mean temperature of 21.96 ºC. In winter (December - February), precipitation accounts for only 3.59% of the annual total. The lowest temperature (- 23.92 ºC) and minimum precipitation (6.42 mm) occur in January, with a daily mean precipitation of 0.21 mm and a daily mean temperature of - 17.85 ºC (Figure 4). The annual effective accumulated temperature ≥10 °C ranges from 2,350 to 2,750 ºC. The frost - free period is 105–115 days in mountainous areas and 120–130 days in hilly areas. The annual average relative humidity fluctuates between 65.9% and 76.5%, with a multi - year average of 70.1%. The coefficient of variation for the monthly average relative humidity is merely 11.77% (Figure 4). The case - study area enjoys abundant sunshine, with annual sunshine hours ranging from 1,975 to 2,574 hours and a multi - year average of 2,242 hours. The maximum (7.32 hours/day) and minimum (4.29 hours/day) sunshine hours occur in May and December, respectively (Figure 4). From 2013 to 2024, the overall air quality in the case - study area was of excellent quality. The average concentrations of PM₁₀, PM₂.₅, SO₂, and NO₂ were 0.064 mg/m³, 0.029 mg/m³, 0.018 mg/m³, and 0.020 mg/m³, respectively, all of which were below the limits stipulated in China's Ambient Air Quality Standards (GB 3095 - 2012) [11]. The proportion of days with excellent or good air quality exceeded 88%.
The growth and development of Ganoderma lucidum are intricately associated with temperature, light, and moisture conditions. In Jiaohe City, the relatively high air humidity (ranging from 56.7% to 61.0%) from March to May facilitates mycelial colonization on the substrate and averts contamination by competitive fungi. From June to September, the temperatures are in accordance with the optimal temperatures for mycelial growth (20–25 °C) and fruiting body development (25–30 °C). The adequate diurnal temperature variations inside greenhouses, combined with sufficient ventilation, are conducive to dry matter accumulation, enhance disease resistance (by inhibiting pest egg incubation, larval development, and adult activity), and effectively prevent infection by competitive fungi. The short sunshine duration in late spring and early summer is beneficial for mycelial growth and primordium differentiation, whereas the long sunshine duration from midsummer to early autumn contributes to increasing greenhouse temperatures and promotes cap thickening.
Figure 4 Statistical analysis chart of climatic characteristics for the case study area (1980–2024)
4.3 Land Use and Vegetation Cover
The authors employed the maximum likelihood method for supervised classification on Landsat 9 imagery with a 30-m spatial resolution to acquire the land use types of the case - study area in 2022[4]. Forest and cultivated land emerge as the predominant land use types, constituting 66.5% and 25.0% of the total area respectively (Figure 5). Leveraging Landsat 5 TM imagery (from 2000 and Landsat 9 imagery (from 2022, the Normalized Difference Vegetation Index (NDVI) for both years was computed, and the trend of annual NDVI change from 2000 to 2022 was analyzed. In 2022, the NDVI values in the case - study area spanned from - 0.13 to 0.63, with a mean value of 0.36, suggesting a moderate degree of vegetation cover. Over the past two decades, the average annual rate of NDVI change in the case - study area was 0.15, and areas exhibiting an increasing NDVI trend accounted for 97.2% of the region, indicating an overall enhancement in vegetation cover (Figure 6). The favorable land use and vegetation cover patterns offer ecological security, encompassing suitable terrain (agro- orestry interlacing, gentle slopes), climate (temperature, humidity, light, etc.), and raw materials (substrate, soil), which are conducive to the cultivation of Ganoderma lucidum.

4.4 Soil Conditions
In May 2025, the researchers gathered a total of 107 soil samples from 0–1 m deep profiles (layers: 0–10, 10–20, 20–40, 40–60, 60–80, and 80–100 cm) at 19 Ganoderma lucidum cultivation sites within the case study area (Figure 2). These samples were dispatched to the Center for Physical and Chemical Analysis, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, for examination.
Soil texture, organic carbon, and macro-nutrient contents serve as core indicators that reflect the soil nutrient status under the combined influence of parent material sources, soil formation processes, and agricultural management practices. According to the international soil particle classification standard, the average contents of clay, silt, and sand in the 0–1 m deep soil profiles of the case study area were 5.24%, 47.92%, and 46.84%, respectively. The soil texture was predominantly silty loam (accounting for 70.1%), followed by sandy loam (accounting for 24.3%) (Table 2). The soil pH ranged from 6.09 to 7.97, with a mean value of 6.70, generally presenting a neutral nature. The soil electrical conductivity (EC) ranged from 11 to 117.2 μS/cm, with a mean of 29.13 μS/cm, indicating soils with low salinity and moderate fertility. The average contents of soil organic carbon, ammonium nitrogen, nitrate nitrogen, total nitrogen, total phosphorus, and total potassium were 12.49 g/kg, 9.14 mg/kg, 6.64 mg/kg, 1.27 g/kg, 0.68 g/kg, and 21.04 g/kg, respectively (Table 2). Approximately 15.9% and 47.7% of the samples reached Grade 3 or above for soil organic carbon and total nitrogen content, respectively, based on the national standard of the Second National Soil Survey. The contents of cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), zinc (Zn), arsenic (As), and mercury (Hg) in all soil layers were below the risk screening values for soil contamination specified in the Soil Environmental Quality - Risk Control Standard for Soil Contamination of Agricultural Land (Trial) (GB 15618 - 2018)[12] and the limits set in the Evaluation Standard for Environmental Quality of Edible Agricultural Products Production Areas (HJ/T 332 - 2006)[13] (Table 3). Pesticide residues such as BHC and DDT were not detected in the soil, conforming to the requirements of GB 15618 - 2018[12]. The 0–1 m deep soil profiles in the case study area demonstrated high nutrient contents and were devoid of heavy metal and pesticide contamination.

4.5 Water Environment Quality
The water quality at the Jiaohekou section consistently met Class III of the Environmental Quality Standards for Surface Water (GB 3838 - 2002)[14]. Meanwhile, the water quality at the Yangqiao and Xinzhan sections of the Lafa River maintained or surpassed Class II standards over the long - term. In May 2025, the researchers collected eight samples of surface water and groundwater from the case study area (Figure 2). At the sampling sites, the pH, electrical conductivity, and total dissolved solids (TDS) were measured with a portable multi - parameter water quality meter. The concentrations of eight heavy metals and eighteen trace elements in the water samples were determined at the Center for Physical and Chemical Analysis, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences. Nitrate, chemical oxygen demand (COD), and five - day biochemical oxygen demand (BOD₅) were analyzed by Hangzhou Yanqu Information Technology Co., Ltd.
The pH values of surface water and groundwater in the case study area ranged from 6.79 to 7.84, with a mean of 7.12, indicating weak alkalinity. The mean values for total dissolved solids (TDS), permanganate index, chemical oxygen demand (COD), five-day biochemical oxygen demand (BOD₅), and nitrate in the water samples were 71.43 mg/L, 2.03 mg/L, 22.13 mg/L, 5.55 mg/L, and 7.10 mg/L, respectively (Table 4). The water quality not only conforms to the Standards for Irrigation Water Quality (GB 5084-2021)[15] and the Evaluation Standard for Environmental Quality of Edible Agricultural Products Production Areas (HJ/T 332-2006)[13] but also meets the Standards for Drinking Water Quality (GB 5749-2022)[16], rendering it suitable as irrigation water for G. lucidum.

4.6 Quality Data of Ganoderma lucidum Cultivation Substrate
The naturally distributed tree species in the case study area are primarily from the temperate Changbai Mountain flora, with a few subtropical and cold-temperate relatives, encompassing over 40 species from 11 families. Major species include Xylosma congestum, elm, and Manchurian walnut. Ganoderma lucidum cultivation in the case study area utilizes Xylosma congestum wood segments as the substrate (Figure 7). Xylosma congestum (Lour.) Merr., an evergreen shrub or small tree of the Salicaceae family, is lauded as the "golden substrate" for cultivating Ganoderma lucidum or the preferred material for "semi-wild" cultivation. In May 2025, the authors collected four samples of X. congestum wood segments from the case study area (Figure 2) and sent them to the Center for Physical and Chemical Analysis, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, for testing.
Figure 7 The material and packaging of Xylosma congestum wood segments, and the substrate after spawn-running
The results indicated that X. congestum wood is hard, dense, and decomposes slowly, providing a stable growth matrix for Ganoderma lucidum. Its fibrous structure facilitates the attachment and expansion of Ganoderma lucidum mycelia. The wood segments are rich in lignin and cellulose, and contain abundant macro-nutrients like nitrogen, phosphorus, and potassium; secondary nutrients like calcium, magnesium, and sulfur; and trace elements such as iron, sodium, and zinc, providing ample carbon and nitrogen sources for the mycelia. These can be converted into absorbable, readily available nutrients by the enzymatic system of the mycelia, fulfilling the growth requirements of the fruiting bodies. The contents of eight heavy metals, including cadmium, mercury, and arsenic, were all below the limits stipulated in Green Food - Environmental Quality for Production Area (NY/T 391-2021)[17] and the Technical Regulations for Standardized Production of Ganoderma lucidum (T/CACM 1374.83-2021)[18] (Table 5). Using X. congestum as a natural substrate, without applying any chemical fertilizers or pesticides during the growth process, effectively reduces the risk of heavy metal and pesticide contamination in the products.

5. Ganoderma lucidum Product Characteristics
Ganoderma lucidum generally pertains to Ganoderma lucidum (Red Reishi). Ganoderma spores are the reproductive cells discharged from the cap during the maturation phase of the fruiting body, containing all the genetic active substances of Ganoderma lucidum. The Shennong Bencao Jing recorded the effects of Ganoderma lucidum as "nourishing lung qi, nourishing liver qi, and nourishing spleen qi." The 2020 edition of the Pharmacopoeia of the People's Republic of China [3] elaborated in detail on the properties and functions of Ganoderma lucidum and its spores. The G. lucidum in the case - study area is mainly Ganoderma lucidum (Red Reishi), featuring individual, non - clustered fruiting bodies with round and regular caps that are brownish - red, having a surface covered with spore powder and a pale yellow or milky - white ventral surface. The stipes are thick, dark brown, and lustrous. The sporoderm - broken spore powder is dark brown, emits a fungal fragrance, and has a delicate and smooth flavor. Polysaccharides, triterpenoids, and adenosine are the principal active components of G. lucidum and its spore powder, demonstrating effects such as immune enhancement, blood circulation promotion, spleen invigoration and lung nourishment, hypoglycemic and hepatoprotective effects, as well as anti - tumor and anti - cancer properties [5, 6, 19, 20].
5.1 Quality of Ganoderma lucidum Slices
Testing of Ganoderma lucidum slices conducted by the authors showed that polysaccharide, total triterpenoid, and adenosine contents ranged from 0.98 to 1.62 g/100g, 0.73 to 1.94 g/100g, and 104 to 152 mg/kg, respectively, with mean values of 1.32 g/100g, 1.23 g/100g, and 138.25 mg/kg (Table 6). These values surpassed the limits specified in the 2020 edition of the Pharmacopoeia of the People's Republic of China[3]. Pesticides including insecticides like deltamethrin, herbicides like 2,4-D, and fungicides like tebuconazole were not detected (Table 6), indicating no pesticide contamination.

5.2 Quality of Sporoderm-Broken Ganoderma lucidum Spore Powder
The test results demonstrated that the average sporoderm-broken rate of the spore powder from the case study area reached 99.2%, with the average contents of total triterpenoids and polysaccharides being 9.16 g/100g and 2.47 g/100g respectively (Table 7). These values exceeded the limits stipulated by the enterprise standards of major manufacturers [21 - 24] and the group standard "Ganoderma lucidum Spore Powder from Changbai Mountain in Jilin" (T/YYTC 008 - 2024) [25]. The mean values of moisture, ash, and peroxide value were 4.83%, 0.80%, and 0.08 g/100g respectively. The contents of heavy metals such as lead, arsenic, and mercury, as well as the counts of aerobic plate, coliforms, and mold and yeast, were below the relevant limits. Pesticides such as BHC and DDT, and pathogenic bacteria such as Salmonella and Staphylococcus aureus, were not detected (Table 7). The contents of ash, lead, arsenic, and mercury in the sporoderm-broken spore powder from the case study area were lower than those reported for products from Guanxian and Guangyi in Shandong, Jinzhai and Jingde in Anhui, and Pingnan in Fujian [26, 27]. Previous research has indicated that the ash content of sporoderm-broken spore powder is lower than that of unbroken spore powder, while the polysaccharide content is higher [27, 28]. The sporoderm-broken Ganoderma lucidum spore powder from the case study area features a high sporoderm-broken rate, is safe, and has higher active component contents compared to products from other regions that use agricultural by - products as base materials.

6. Ganoderma lucidum Industry Operations and Management
6.1 Socio-Economic Overview of Jiaohe City
The statistical communiqués on the national economic and social development of Jiaohe City from 2013 to 2024[5] indicate that the total population decreased from 445,700 to 392,000. Simultaneously, the rural population declined from 277,000 to 231,000, and the urbanization rate increased from 37.83% to 41.07%. The Gross Regional Product (GRP) decreased from 21.205 billion RMB to 10.660 billion RMB. Specifically, the added - value of the primary industry declined from 3.578 billion RMB to 2.980 billion RMB. The industrial structure ratio changed from 16.9:50.0:33.1 to 27.9:19.6:52.5, demonstrating a significant decline in the proportion of the secondary sector and a strong growth trend for the tertiary sector. The urban per capita disposable income increased from 17,490 RMB to 31,619 RMB, with an average annual increment of 1,177 RMB. The rural per capita disposable income rose from 10,012 RMB to 21,280 RMB, with an average annual increment of 939 RMB.
6.2 Cultivation History and Industrial Development
The exploration and utilization of Ganoderma lucidum in China can be traced back 6,800 years. As per the earliest pharmacological treatise in China, the Shennong Bencao Jing, Ganoderma is categorized into six varieties: Zi Zhi (Purple Ganoderma), Chi Zhi (Red Ganoderma), Qing Zhi (Green Ganoderma), Huang Zhi (Yellow Ganoderma), Bai Zhi (White Ganoderma), and Hei Zhi (Black Ganoderma), characterized by a sweet taste and a neutral property. Medical records from the Han, Tang, and Song dynasties, including the Shang Han Lun and Jin Kui Yao Lue, contain relevant descriptions. During the Ming Dynasty, works such as the Bencao Gangmu, Weinan Bencao, and Bencao Yuanshi offered comprehensive accounts of the morphology and medicinal efficacy of Ganoderma lucidum.
Jiaohe City is rich in wild G. lucidum resources (Figure 8). Villagers have been collecting wild G. lucidum for nearly a century. In the spring of 1989, the first Changbai Mountain Red Reishi was cultivated in Huangsongdian Town, pioneering artificial cultivation. According to the Jiaohe City Annals (1998–2003), large-scale artificial cultivation in Jiaohe City began in 1995. In 2001, Huangsongdian Town, a primary production area for Jiaohe G. lucidum, was designated an Organic Ganoderma lucidum Production Base by the Food and Agriculture Organization of the United Nations (FAO). In 2005, Huangsongdian Town was recognized as a National Outstanding Base Township for the Edible (Medicinal) Fungi Industry by the China Edible Fungi Association. In 2009, Huangsongdian Town pioneered the introduction and optimization of axial flow fans combined with specially designed collection bags for spore powder harvesting, achieving low-loss, high-efficiency collection. In July 2015, the Ministry of Agriculture approved the registration of "Huangsongdian Ganoderma lucidum" as a National Agro-product Geographical Indication. In 2018, "Huangsongdian G. lucidum" was approved by the State Administration for Industry and Commerce as a China Geographical Indication Certification Trademark.
Figure 8 Wild Ganoderma lucidum in the case study area
In the past two decades, the Huangsongdian Edible (Medicinal) Fungi Association has been founded, and enterprises specializing in the deep - processing of Ganoderma lucidum, such as "Beizhi," "Fuzhidao," and "Jinzhilou," have emerged in succession. These enterprises integrate scientific research, cultivation, processing, sales, technical consultation, and training related to edible and medicinal fungi. They supply medicinal fungal raw materials to major domestic Ganoderma lucidum enterprises, pharmaceutical factories, health product manufacturers, and research institutions. In 2022, taking advantage of the "Huangsongdian Ganoderma lucidum Geographical Indication Protection Project" initiated by the Ministry of Agriculture and Rural Affairs, a 1,000 - greenhouse Ganoderma lucidum cultivation base was established. By 2024, seven workshops in Jiaohe City met the Good Manufacturing Practice (GMP) standards, and 17 health food registration and filing approvals were obtained.
Currently, the Ganoderma lucidum product categories in Jiaohe include Ganoderma lucidum slices, Ganoderma lucidum cubes, sporoderm - broken Ganoderma lucidum spore powder, Ganoderma lucidum spore oil, Ganoderma lucidum pancakes, and Ganoderma lucidum bonsai. A comprehensive industrial chain production model has been established, which encompasses spawn cultivation, technical guidance, corporate buy - back, and deep processing into high - value - added products. The production model has transformed from an extensive production and low - price sales model to new business formats integrating e - commerce live streaming and culture - tourism integration. The products are sold to 31 countries and regions, including Japan, South Korea, and the United States.
From 2014 to 2025, the scale of G. lucidum cultivation in Jiaohe City expanded from 917 greenhouses (1.1 million segments) to 3,272 greenhouses (3.6 million segments). Total output, G. lucidum yield, and spore powder yield increased from 343.9 tons, 229.3 tons, and 114.6 tons to 1,300 tons, 850 tons, and 450 tons, respectively. The output value grew from 25.905 million CNY to 98 million CNY (Table 8), making it a significant industry for rural revitalization and farmers' income growth.

6.3 Ganoderma lucidum Cultivation Management
Production bases are established in areas with altitudes exceeding 350 m, characterized by favorable ecological conditions, level terrain, convenient irrigation and drainage systems, and the absence of pollution sources within a 5 - kilometer radius and 20 - kilometer upwind area. Greenhouse cultivation is employed, with dedicated sites for spawn segment preparation, spawn running, and fruiting (Figure 9). The "Jiaohe Model," which is adapted to the local climate, raw materials, soil, and water environment, has been developed:
(1) Cultivation Techniques
Fresh wood of Xylosma congestum harvested during the period from the Winter Solstice to the Beginning of Spring is utilized. Straight trunks and branches are cut into segments with a length of 13–15 cm and evenly split. Segments with a diameter less than 7 cm and twigs do not necessitate splitting; segments with a diameter of 7–10 cm are split into two parts; segments with a diameter exceeding 10 cm are split into 4–6 pieces. The processed wood segments are bundled into circular bundles with a diameter of approximately 30 cm, placed in bags, and the bags are tightly sealed (Figure 7). The wood segments undergo sterilization, disinfection, inoculation, and spawn - running processes. Greenhouses are oriented in a north - south direction, with a length of 24 m, a width of 7 m, and a height of 2.2 m. Drainage ditches are dug at the ends and sides, 0.5 m away from the greenhouse. Approximately 1,200 segments are placed in each greenhouse, and they are given a 7 - day resting period before being transferred to the soil. When the temperature consistently exceeds 25 °C, the nursery beds are leveled. The plastic bags are removed, and the inoculated ends of the segments are placed facing upwards on the beds. The segments are positioned at a distance of 1–1.5 m from the greenhouse entrance, with an inter - segment distance of 3–5 cm and a row spacing of 8 cm, and then covered with 2 cm of soil. Water reservoirs, pumps, and water pipelines are configured in accordance with the base scale. An irrigation system is installed, which is connected to rotating in - ground misting sprinklers (Figure 9).
(2) Greenhouse Management
The initial watering is carried out 10 days subsequent to soil covering. Germination is triggered when temperatures persistently surpass 28 °C. Throughout the germination phase, soil moisture is preserved while waterlogging is precluded, with due consideration given to ventilation and warming. When temperatures fall below 20 °C or during consecutive overcast days, supplementary scattered light is supplied to facilitate primordium formation.
During the bud stage, both soil and air humidity within the greenhouse are sustained, with watering conducted approximately 5 times per day. The frequency of watering is decreased or halted on rainy days and appropriately augmented on sunny days. When buds attain a height of approximately 7 cm, thinning is implemented, retaining 1–2 robust buds per segment.
During the cap expansion stage, frequent misting is employed to maintain a humid atmosphere inside the greenhouse. Light distribution is uniform, and adequate ventilation is ensured within 40 cm above the ground level to guarantee sufficient stipe length and flat cap expansion. If adjacent fruiting bodies are in close proximity, the segments are rotated and re - covered with soil in a timely fashion.
During the spore ejection stage, the temperature inside the greenhouse is regulated within the range of 28–35 °C. Appropriate misting is utilized to preserve soil moisture, while daytime air humidity is maintained at 50%–60%. The entrance area of the greenhouse is shaded to prevent direct sunlight from irradiating the fruiting bodies near the entrance, and adequate ventilation is provided to ensure normal sporulation.
Each greenhouse is equipped with two 350 W or 500 W spore collection fans. Ropes are tied from the greenhouse roof pipes to the fans, which are positioned 3 m from the entrance and 1 m above the ground. The fans are connected to collection bags suspended inside the greenhouse (19 m long, 0.5 m diameter). During the collection process, the fans operate continuously for 24 hours, the collection bags are tapped 3–4 times per day, and the spore powder is collected from the bags each morning (Figure 9).
(3) Harvesting and Drying
Collected spore powder must be spread out thinly and air-dried promptly or microwave-dried at 50–60 °C, then bagged and stored at low temperatures. Fruiting bodies are harvested after the sporulation phase ends. The stipe is cut at the connection point with the wood segment, and any adhering soil is removed. The caps are placed face down, arranged individually, or the fresh G. lucidum is sliced and dried or air-dried. Once the moisture content falls below 11%, the product is graded and packaged (Figure 9).

6.4 Near-Real-Time Ganoderma lucidum Habitat Monitoring System
To enable near-real-time monitoring of the G. lucidum habitat, a Jiaohe Ganoderma lucidum Geo-Ecological Environment Ground Station was established at the Sanhe Village cultivation base in Huangsongdian Town in May 2025 (Figure 10). This ground station is a low-power Internet of Things (IoT) sensing system. It dynamically monitors and records habitat factors such as air temperature, precipitation, wind speed, wind direction, relative humidity, atmospheric pressure, light intensity, negative oxygen ions, soil temperature at 0–10 cm, 10–20 cm, and 20–30 cm depths, soil moisture content, and soil electrical conductivity, as well as processes such as G. lucidum growth and spore powder collection, and transmits the data back in real time.

7. Discussion and Conclusion
Ganoderma lucidum is a fungus of the genus Ganoderma with health-promoting properties and high economic value. Its industry possesses broad development prospects and requires integrated development in terms of government support, industry-academia-research collaboration, and marketing promotion.
7.1 Deepening Technological Innovation, Addressing Continuous Cropping Obstacles, and Enhancing Industrial Benefits
National and local laws and regulations on the conservation and utilization of G. lucidum are insufficient, leading to occasional illegal harvesting of wild germplasm resources. Research on the selection and breeding of high-quality varieties for artificial cultivation lags, or selected varieties are unsuitable for industrialized cultivation management. Except for a few leading enterprises, the G. lucidum industry focuses primarily on cultivation and primary product processing, signifying a need to strengthen large-scale, standardized cultivation and deep processing. Scientific and technological transformation in the G. lucidum industry is insufficient, with weak talent cultivation and technical reserves. Currently, many enterprises focus on developing spore powder product lines, while the development and marketing of G. lucidum products in the broader wellness sector are relatively lacking. In the future, there is a need to strengthen the protection of G. lucidum germplasm resources, breed new, high-quality varieties, develop standardized cultivation management technologies, and deepen technological innovation and empowerment.
As the scale of G. lucidum cultivation continues expanding, continuous cropping obstacles have become a bottleneck problem constraining the development of the G. lucidum industry in Jiaohe City, demanding effective solutions urgently. In the short term, there is a need for the comprehensive optimization of cultivation methods, soil disinfection, and biological control and regulation techniques. In the medium term, variety selection and breeding and facility construction need strengthening. In the long term, regional crop rotation planning and ecological circular agriculture should be promoted. Furthermore, promoting base-oriented operations centered on land transfer is a key measure to propel the Jiaohe G. lucidum industry beyond land resource constraints. First, diversified models such as reverse contracting through "cooperatives + farmers," large-scale leasing by enterprises, or joint-stock cooperation should guide farmers to transfer scattered land long-term and concentratedly to new types of agricultural business entities, forming large-scale cultivation bases with clear property rights and stable tenure. Second, unified planning and zoning should be implemented for the transferred contiguous land, promoting a rotation system of "G. lucidum cultivation — green manure incorporation/fallow — soil disinfection." Finally, integrated policy support should be strengthened, with the government establishing transfer service platforms, providing fiscal and financial support, and building a solid coupling mechanism for risk-sharing and benefit-sharing.
7.2 Improving Standard Systems, Strengthening Market Supervision, and Enhancing Brand Influence
Currently, most health foods derived from sporoderm-broken G. lucidum spore powder use total triterpenoid content as a functional marker. However, national standards, health food catalogs, and technical requirements lack clear stipulations on the detection method for total triterpenoids specific to spore powder and derived products. The domestic G. lucidum spore powder industry is characterized by a competitive landscape of "numerous enterprises, low concentration, regional brands predominating, and uneven quality." Industrial brand building is lagging, with low market recognition and weak competitiveness, hindering the realization of premiums for high quality. The *National Report on the Development of Characteristic Rural Industries (2024)*[7] pointed out a lack of distinctive G. lucidum varieties and severe homogeneous competition, making it difficult to meet the demand for high-quality, differentiated raw materials in specific medical and health care fields, thus hampering the enhancement of industrial added value. In the future, efforts should focus on innovating product types, improving quality testing and environmental protection standard systems, expanding the industrial chain, strengthening brand building, enhancing market supervision and risk warning, adapting to market environment changes, and ensuring the high-quality development of the G. lucidum industry.
