On the outskirts of Datong, north China's Shanxi Province, workers harvest tomatoes using intelligent lift vehicles inside a smart greenhouse. Automated systems regulate temperature and humidity 24/7, coconut-fiber substrates block soil-borne pests, and precision irrigation delivers nutrients by the minute. The result: yields of nearly 250 metric tonnes per hectare, four times higher than traditional greenhouses. With its cool climate, ample water availability, and commendable transport links, Datong is rapidly expanding facility agriculture.
