Amid the mountains of Enshi in Hubei Province, a wild herb known as "Youyou Grass" is quietly becoming a "golden leaf" for local farmers. But what is truly electrifying this land is not traditional farming know-how, but a torrent of data from Chongqing. In early spring 2025, an agricultural big data experiment along the Hubei-Chongqing border propelled "Youyou Grass"—a name once found only in herbalists' baskets—onto center stage of industrial transformation.

It all began last autumn. A Chongqing-based tech company called "Digital Green Vein" crossed the provincial boundary with its self-developed agricultural big data platform and plunged straight into the core production area of Youyou Grass in Lichuan City, Enshi Prefecture. At first, local veteran farmers were skeptical. "We've been growing this grass for decades, and now a computer is going to teach us?" But when the first planting advisory report—based on satellite remote sensing, soil sensors, and over 2,000 historical weather records—landed on their desks, they realized this collaboration was no mere gimmick.

"We used to rely on the heavens for our harvest. This year, with all the rain, the roots of the Youyou Grass rotted away on a large scale, and we lost everything," said Chen Defu, a large-scale grower in Tuanbao Town, Lichuan City, squatting on a ridge and pointing to an alert on his phone screen. "Now the platform pushed a 'high risk of root rot' warning three days in advance. I used a drone to spray biological agents, and we saved about 70 to 80 percent of the yield per mu." Data shows that in the pilot areas, the average yield per mu of Youyou Grass surged from 320 kilograms to 480 kilograms, with the premium-grade rate rising by nearly 40 percent.

The underlying logic of this "Hubei-Chongqing joint effort" lies in data breaking down administrative barriers. Youyou Grass grows in the Wuling Mountain area, spanning Hubei and Chongqing. In the past, farmers on both sides worked in isolation, with limited information, leading to severe price volatility—last year, when Chongqing's producing areas had a bumper harvest, Hubei suffered from unsold stock due to blind expansion, and the purchase price per jin plummeted from 15 yuan to 6 yuan. Now, the big data platform integrates real-time inventory, logistics trajectories, and terminal pharmaceutical companies' procurement demands from over 400 cooperatives across both Hubei and Chongqing, creating a unified scheduling network. In February, the platform detected an urgent need from a Chongqing pharmaceutical company for a batch of high-content Youyou Grass extract. It automatically matched 12 planting bases in Enshi at altitudes above 800 meters with yellow loam soil, completing the entire process from order to loading within 48 hours.

"This is not just technology going to the countryside; it is a digital restructuring of production relations," emphasized Li Min, an associate researcher at the Hubei Academy of Agricultural Sciences, who participated in the project planning. "The core of the 'Youyou Grass Hubei-Chongqing Big Data Platform' lies in three 'breakthroughs': bridging the connection between land and market, breaking the isolation of inter-provincial agricultural data, and closing the last mile between small farmers and big data." At the Enshi Prefecture Big Data Center, a reporter saw a massive screen displaying real-time metrics: heat maps of planting areas, pest warning levels, logistics vehicle trajectories, price index curves... Behind every number lies a specific piece of land and a farming household's livelihood.

Of course, the transformation has not been without challenges. Network coverage in some remote mountainous areas remains unstable, and some elderly farmers face a steep learning curve with smart devices. However, local governments have launched a "Digital New Farmer" training program. The first batch of 200 "data liaisons" are now visiting villages and households, teaching farmers hands-on how to view data reports on their phones. On the Chongqing side, the municipal agricultural cloud platform has opened its API interface, allowing Youyou Grass data to synchronize in real time with the Southwest China Traditional Chinese Medicine Trading Center.

Standing at the Youyou Grass demonstration base in Lichuan City at an altitude of 1,200 meters, one can see rows of solar-powered sensors faintly visible through the morning mist. The wind rustles through the leaves—a sound that was once nature's whisper, now being transformed into a language of zeros and ones, flowing along fiber optic cables to distant places. Perhaps, as a local village official put it: "Youyou Grass is still the same grass, but with big data, it's no longer a 'luck-dependent' wild weed."
