Conservation tillage can reduce wind erosion and water erosion, reduce the number of soil tillage, reduce soil compaction, protect and improve the soil structure, so as to improve sowing quality and increase crop yield, which is an important measure to develop agriculture. This paper introduces the current development of no-till planter at home and abroad, discusses the requirements of conservation tillage on no-till planter and the problems of no-till planter in our country, and discusses the development of no-till planter in our country Prospects, pointed out that no-tillage planter in our country has a vast space for development.
