Integration Technology of Agricultural Machinery and Agronomy for Green Onion Planting in Tianjin City

Integration technology of agricultural machinery and agronomy for green onion planting in Tianjin City was analyzed.Based on analysis of agronomic requirements of green onion planting，matching selection of agricultural machinery and requirements of mechanized operation，technical mode of integration of agricultural machinery and agronomy for green onion planting was summarized，which was suitable for popularization and application in Tianjin City.Benefit analysis on this model showed that economic benefit was about 67 125 yuan/hm2，economic benefit was profitable.It was suggested that factory seedling breeding base should be established in the future，socialized service of agricultural machinery should be actively developed，agricultural machinery and agronomic integration technology test should be carried out，and agricultural mechanization technology and equipment should be introduced and demonstrated，and problems of mechanized joint harvest operation should be solved as soon as possible.
