摘　　要：针对目前国内免耕播种机存在防堵机构复杂、制造成本高、功耗大等问题,研究设计了一种免耕气吸式播种施肥机。田间试验表明:该机具能够在较简单防堵机构的作用下完成免耕播种作业,玉米粒距合格率达到了97.1%,播种平均深度为35mm,施肥平均深度为88mm,种肥间距为53mm,一次进地可完成破茬、开沟施肥、播种、镇压等作业,作业时土壤扰动小,作业质量满足农艺要求。The no - till corn planter is designed to solve the problems of complex device for no - blocking and cost of manufacture and power consumption. The results approved that the planter could finish the seeding through simple device for no - blocking in the field with straw covering. The qualified rate for space of seeds is 97.1%, the average depth of seeds and fertilizer and the distance between them are 35mm, 88 mm and 53mm. This planter could perform the corn rootstalk cutting, opening, fertilizing, seeding, packing and covering operations at one time.
