水稻直播省去了水稻种植中育秧、拔秧、移栽等繁琐环节,是水稻轻型栽培技术中最简单的种植方式,劳动强度低,种子消耗少,效益高,操作方便,具有广阔的发展前景。针对现有水稻直播机播量大和均匀度差的问题,对水稻精密直播机排种器进行了设计。 Rice direct-seeded saves the cumbersome links such as seedling-raising, pull-out seedling and transplanting in rice planting. It is the simplest planting method in rice light-cultivation techniques. It has the advantages of low labor intensity, less seed consumption, high efficiency, convenient operation and broad development prospect . In view of the problem of large amount of sowing and poor evenness of the existing rice direct seeding machines, a precision seed sowing machine of rice was designed.
