The Zhangqiu people in Shandong have established a Green Onion Agricultural Industrial Park, which uses high-tech technology to manage green onions more easily, accurately, efficiently, and conveniently. The big data platform allows farmers to view soil data and irrigation records in real-time, and intelligent equipment can be implemented on-site for environmental regulation, agricultural operation, disaster warning, and pest control. The Rural Bureau of Zhang Tomb District has also engaged in green onion seedling cultivation, nursery cultivation, and crop selection and breeding, making Zhangfen green onions available all year round for sale. This has resulted in the four-season fresh onion industry becoming a significant industry in the collective economy of Zhangqiu Village, providing employment for over 100,000 people and generating an annual output value of over 700 million yuan.
