摘　　要：水稻旱直播是水稻种植技术中最简单的播种方式,省时省力,效率高。针对当前农村剩余劳动力大量转移和传统的育秧、移栽种植方式费工费力等问题,研制一款新型水稻旱直播机,一次下地可完成种床旋耕、播种、施肥、镇压等多项作业。试验结果表明,该机具水稻出苗率≥85%,作业效率高,省时省工,可提高我国水稻种植机械化水平。Rice dry-direct seeding is the simplest planting method in rice planting technology,which is time-saving,labor-saving,highly efficient and highly recognized by the common people.However,with the massive transfer of rural surplus labor force,as a traditional way of seedling raising and transplanting cultivation,there is a contradiction between them.In response to this problem,we developed a new type of rice dry direct seeding machine,which can complete a variety of operations such as rotating cultivation,sowing,fertilization,suppression and so on.The experiment shows that the machine has high efficiency,time and labor saving,and greatly improves the level of rice planting in China.
