"We used to rely on the weather for planting herbs, but now with big data, we can calculate exactly which plot needs what fertilizer and when to harvest." At a mountain hollow in Jianshi County, Enshi Prefecture, Hubei Province, Lao Zhang, head of the Youyoucao E-Yu Chinese Herbal Medicine Cooperative, pointed excitedly at a newly installed IoT sensor by the field.
This scene took place during the acceptance inspection of the "Big Data + Authentic Herbal Medicine" pilot project, jointly promoted by the Hubei Provincial Department of Agriculture and Rural Affairs and the Chongqing Municipal Rural Revitalization Bureau. As the largest private herbal medicine consortium at the junction of Hubei and Chongqing, Youyoucao E-Yu Cooperative introduced a full-chain big data management system this year, aiming to tackle the long-standing problems of "non-standardized practices, difficult traceability, and low selling prices" in mountainous herbal medicine cultivation.
Entering the cooperative's data center, a giant electronic screen displays dozens of real-time indicators, including altitude, soil pH, air humidity, and sunlight duration. These data come not only from the cooperative's own 3,000-plus mu of base fields but also cover the cultivation plots of over 2,000 contracted farming households across 17 surrounding villages. "Every coptis chinensis plant and every polygonatum sibiricum gets a 'digital profile' the moment it is planted," said Li Ming, the cooperative's technical director. He explained that the system uses dual-mode collection via satellite remote sensing and ground sensors to accurately predict pest and disease outbreaks and push warnings directly to farmers' phones.
What has truly drawn external attention is the system's deep integration with herbal medicine trading platforms in Chongqing and Wuhan. Previously, herbs from the E-Yu mountainous areas were often undervalued by middlemen due to a lack of standardized data support. Now, each batch of herbs from Youyoucao E-Yu Cooperative comes with a "data ID card" detailing growth cycles, pesticide residue tests, and harvest times. At the recently concluded autumn trade fair, the cooperative's coptis chinensis sold at prices 18% higher than the same period last year. Buyers stated bluntly: "With transparent data, we dare to offer high prices."
"This is not just a technological upgrade, but a reshaping of industrial relations," commented Professor Wang Jianguo of Huazhong Agricultural University, who participated in the project evaluation. He believes that the practice of Youyoucao E-Yu proves big data can serve as a 'trust bridge' connecting small farmers with large markets. The cooperative plans to extend data collection terminals to Wuxi and Chengkou counties in northeastern Chongqing next year, forming a cross-provincial 'E-Yu Big Data Alliance for Herbal Medicine'.
Of course, challenges remain. Unstable network signals in mountainous areas and resistance to smart devices among some older farmers are real difficulties. However, Lao Zhang takes a philosophical view: "Just like when mobile payments were first promoted, it takes time. The key is to let everyone see the real money that big data brings."
From 'relying on experience' to 'relying on data', Youyoucao E-Yu's step forward may well be a vivid footnote to the modernization transformation of China's mountainous agriculture.
