Development status and prospect of potato precision seeding technology
China is a big potato producer in the world,with a large scale and wide range of potato cultivation.Potato planting has many problems,such as complicated process,high labor intensity and low efficiency,so it is very important to study potato mechanization planting.At present,different seed arrangement technologies are applied to potato mechanized planting.Spoon chain seed arrangement device has simple structure and stable transmission.The air suction seed arrangement device can realize precise seed arrangement,and needle seed arrangement device has better adaptability to potato planting.In order to solve the problem of missing seeding in the process of mechanized seeding,the detection and automatic compensation technology of missing seeding is of great significance to improve the efficiency of potato seeding.Therefore,the research status of potato precision seed arrangement technology at home and abroad was analyzed,and the differences between different seed arrangements were compared.The problems of potato precision seed arrangement at the present stage were expounded,such as missing sowing,large power consumption and large damage to seed potatoes,which could provide reference for the research of potato precision seed arrangement technology.
