天津市大葱生产农机农艺融合技术

研究了天津市大葱生产农机农艺融合技术，针对大葱种植农艺要求、农机配套选型和机械化作业要求等进行分析，总结出适合天津推广应用的大葱农机农艺融合技术模式。对模式进行了效益分析，其种植收益约67 125元/hm2，经济效益可观。建议今后建立工厂化育苗基地，积极发展农机社会化服务，继续开展农机农艺融合技术试验，引进示范各环节农机化技术及装备，早日解决机械化联合收获作业难题。 

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.
