Even as lingering cold snaps still grip Northeast China’s Jilin province in mid-April, a cutting-edge smart agricultural facility in Changchun is bucking traditional seasonal constraints to produce bountiful, high-quality cherry tomatoes year-round.
Located within the Changchun National Agricultural High-Tech Industry Demonstration Zone, the 77,000-square-meter intelligent greenhouse operated by Hengtong Ecological Agriculture Technology Development Co is a showcase of modern, data-driven agriculture. Unlike open-field farms that rely on natural weather conditions, every element of cherry tomato growth here is fine-tuned by a connected digital system: sensors woven through rows of climbing tomato vines continuously collect real-time data on plant development, feeding insights to a centralized big data platform that automatically adjusts water, fertilizer, light, temperature, air flow and heat. Every management task, from drip irrigation to environmental regulation, can be completed remotely with a single click.
First launched for construction in 2024, the facility’s 36,000-square-meter planting center is already fully operational, turning out consistent yields that outperform traditional cultivation by a wide margin. “We hit an annual output of more than 300 metric tons, with a steady daily harvest of one ton,” explained Xu Lihui, chairman of Hengtong. “On the same plot of land, our total yield is three times higher than open-field growing. Where traditional cherry tomato harvests only last around four months a year, we harvest 12 months out of the year—even during Jilin’s frigid deep winters, our vines stay heavy with ripe, plump fruit.”
The intensive, technology-driven design of the plant factory maximizes land productivity while cutting down on agricultural inputs. Growing cherry tomatoes in a sterile, soilless environment, paired with AI-powered precision control of growth conditions, has drastically reduced the need for synthetic fertilizers and pesticides. Automated transport robots and guided vehicles navigate the greenhouse by scanning ground QR codes, handling logistics tasks assigned by the central system to cut down on labor needs and reduce human error.
This focus on optimized, controlled growing translates directly to premium product quality. Ripened from flowering to maturity under consistently perfect conditions, the greenhouse-grown cherry tomatoes boast thin, crisp skin, rich juiciness and a naturally sweet flavor that has resonated with upscale buyers across China’s major cities. Today, the company’s output is in high demand at high-end supermarkets, membership-based fresh food chains and corporate bulk buyers in Beijing, Shanghai, Guangzhou and Shenzhen.
To meet growing market demand, Hengtong is already expanding its operations. By the end of 2026, the company will complete construction of a second 42,000-square-meter plant factory dedicated to cultivating high-quality seedlings for vegetables, flowers and medicinal herbs, as well as scaling up production of new specialty varieties of cherry tomatoes, cucumbers and strawberries for both domestic and international markets. A 24,000-square-meter agricultural science center will also open to the public as an educational and outreach hub.
Once the expansion is fully completed, the project is expected to deliver far-reaching benefits beyond its own production output. It will create roughly 300 local jobs for residents in surrounding communities, while driving coordinated growth in supporting local industries including logistics, agritourism and catering, unlocking simultaneous improvements to the region’s economic output, ecological sustainability and social well-being.
