The mystical region along the 33rd parallel north, celebrated for its unique climate, soil, and ecological conditions, is widely recognized in the industry as the "golden belt" for shiitake mushroom cultivation. Nestled deep in the Funiu Mountains, Xixia County in Nanyang City, Henan Province, sees 300 million shiitake mushroom bags thriving here each year.
After more than three decades of development, the shiitake mushroom industry in Xixia has faced persistent challenges. Traditional mushroom sheds relied on manual experience for environmental control, resulting in annual output fluctuations of ±20%, a contamination rate for fungus sticks consistently above 8%, and average annual economic losses exceeding 200 million yuan. As international premium markets demanded more comprehensive traceability data, and domestic demand for ready-to-eat fresh mushrooms grew year over year, Xixia began exploring the integration of information technology to drive precision, automation, and intelligence in its shiitake mushroom sector.
Making Mushroom Cultivation Smarter
Traditional shiitake mushroom farming has long been constrained by natural environmental conditions, with temperature, humidity, light, and air quality dictating outcomes. Farmers planted in early spring, worked through year-end, and left summer and autumn idle. To address these pain points, Xixia County has leveraged digital technology, smart equipment, and scientific research innovation to establish a fully digitalized and intelligent cultivation system spanning strain development, fungus stick preparation, greenhouse management, and farming operations.
First, in the production phase, an IoT-based multi-dimensional sensing network has been deployed to collect real-time data on temperature, humidity, light, and air quality within mushroom sheds. A dynamic regulation model enables precise environmental control: temperature fluctuation is maintained within ±0.5°C, humidity variation stays at or below 2%, and CO₂ concentration adjustment accuracy reaches 50 ppm. Mushroom fruiting uniformity has improved to 95%, and energy consumption per shed has dropped by 40% annually.
Second, in the fungus stick preparation stage, automated intelligent production lines have been established, incorporating vision-based bagging machines with 0.1mm precision and high-pressure sterilization digital twin systems achieving a 99.99% sterilization pass rate. Each fungus stick and mushroom shed is assigned a "digital passport" documenting raw material and process data, ensuring full-process quality control from sourcing to manufacturing.
Third, in the cultivation management phase, a digital farming system has been developed to intelligently push precise agricultural plans covering 12 dimensions based on the growth stage of the mushrooms. An AR-based remote guidance system enables experts to annotate online and provide remote diagnostics, enhancing the timeliness and coverage of technical support.
Fourth, in strain development, a "shiitake germplasm resource gene bank" has been built through county-institute cooperation. Machine learning is used to screen for high-yield and disease-resistant strains, raising the improved variety adoption rate from 65% to 95%. An intelligent correction system for fungus stick production automatically detects bagging tightness and moisture content, reducing defect rates by 90% and achieving standardized, high-quality output from the very source.
Technological Innovation Enables Year-Round Harvests
In its ongoing push to foster healthy industry growth, Xixia has achieved a comprehensive upgrade through the introduction of new varieties, improved mushroom shed facilities, the promotion of "four-season fruiting" technology, and the "centralized stick production, decentralized fruiting" model. These technological advancements have transformed mushroom fruiting from a winter-spring-only cycle to year-round production across all four seasons, extending the fruiting period by three to four months and boosting per-mu returns by 4,500 yuan.
Today, the county's standardized bases report over 90% adoption of premium shiitake varieties and centralized stick production, a summer survival rate for fungus sticks above 95%, and modernization and mechanization levels exceeding 80%. Technological innovation has delivered tangible economic benefits to the industry.
In Xiaoshui Village, Shuanglong Town, Xixia County, 43 standardized intelligent mushroom sheds stand in orderly rows. The village maintains a stable cultivation scale of 2 million fungus sticks, producing 3,000 tons of fresh mushrooms and 300 tons of dried mushrooms annually, with a yearly output value of 16 million yuan. This supports over 100 local residents with nearby employment and adds more than 60,000 yuan to the village collective economy each year, making it a model village for standardized and intelligent mushroom cultivation across the town.
"In the past, summer heat made sheds unusable, and we only worked one season a year. Now with climate-controlled sheds, we harvest mushrooms in every season and earn income all year round. Each shed yields an extra crop, and our income has doubled," said one local farmer, expressing delight at the new cultivation model.
Building a Global Brand
Through technological upgrades and the conversion of research into practical applications, standardized cultivation has boosted yields by more than 10% compared to non-demonstration areas, significantly enhancing the quality of Xixia shiitake mushrooms. As the industry has evolved, "Xixia Shiitake Mushrooms" have been listed in both the "2024 China Agricultural Brand Directory - Regional Public Brand List" and the "2024 Geographical Indication Protection Project Implementation List," with brand influence continuing to expand.
Entering Xixia, billboards advertising "Zhongjing Mushroom Sauce, Truly Savory and Nutritious" are hard to miss. At the Zhongjing Food Factory in Xixia County, an array of mushroom-based processed foods—including mushroom sauce, mushroom oyster sauce, and dried mushrooms—fills the shelves.
Currently, mushroom cultivation in Xixia County remains stable at 300 million fungus sticks, yielding 300,000 tons of fresh mushrooms annually with an output value of 3 billion yuan. The comprehensive benefits of the entire industrial chain exceed 26 billion yuan. The industry directly employs over 200,000 people, with 60% of farmers' per-capita net income derived from mushroom cultivation.
Riding the momentum of the Belt and Road Initiative, Zhongjing Mushroom Sauce has earned a spot among the first 100 Chinese geographical indication products protected under the China-EU Geographical Indications Agreement. It now exports to more than 30 countries and regions, including France and Russia, with annual exports surpassing 1 billion USD and cumulative export earnings exceeding 10.7 billion USD. The international reputation of "Xixia Shiitake Mushrooms, Unrivaled Under Heaven" continues to grow.
The humble mushroom, rooted in the fertile soil of Funiu Mountain and empowered by digital innovation, has completed a remarkable transformation from a traditional agricultural product to a benchmark of smart agriculture, and from a local specialty to an internationally recognized brand. Leveraging its natural endowments and supported by continuously evolving digital technologies and industrial innovation, Xixia's shiitake mushroom industry is thriving, steadily advancing on the broad path of rural revitalization. This small mountain mushroom continues to generate immense value, explore global markets, and create new prospects for the future.
