摘　　要：保护性耕作体系推广实施的关键环节之一是需要性能完善、质量可靠的保护性耕作专用机具,免耕播种机就是其中的重要配套机具之一。机具的土壤工作部件作业质量的好坏直接影响着机具整体的性能。为此,综述了免耕播种机土壤工作部件的特点,重点介绍了破茬和开沟部件的研究发展,讨论了目前免耕播种机土壤工作部件存在的问题,为今后继续研究提供了参考。One of the most pivotal tache in exploration and implementation of the protective cultivation system is professional protective cultivated instruments which have perfect performances and credible qualities. No - tillage planting machine is one of these wonderful instruments. And the performance of the whole machine conditioned by the qualities of the soil Parts. Therefore, this thesis summarizes the characteristics of the soil Parts of no - tillage planting machine. The emphases of this paper is on the point of the development of the soil Parts Of no - tillage planting machine . In the end, discussing some problems in the researching of no - tillage planting machine Make a certain direction for the further study.
