Water spinach seedlings are generally divided into old vine seedlings and seed seedlings. Seed seedling is more convenient, the technical content is not high, and the technical requirements of old vine seedling are higher. At present, in Sichuan and Chongqing, people use old vines to accelerate the germination of water spinach seedlings, because water spinach grown by seed seedlings is not popular in the market because of its poor taste. Dai Jinguo, known as the master of spinach, devoted his life to vegetable cultivation, especially spinach cultivation in greenhouse. At present, there is a demonstration base of spinach high-yield technology in Yongcheng Town, Qijiang District, Chongqing, 13635403738.
