摘　　要：阐述了作物根茬处理机具的现状,对几种不同类型根茬处理复合作业机具及其刀具的结构、性能和特点进行了分析,指出了普遍采用的灭茬机具存在的问题,提出了灭茬机具今后的研究方向。其中,包括对灭茬刀具进行改进,降低功耗、增强其抗磨性及将农机与农艺结合。The status of stubble cleaners and blades, especially for maize, was introduced. The structure, performance, and characteristics of a few types of stubble cleaners and blades widely used in China were analyzed and discussed. On the basis of analyses and discussion, the problems of high-energy consumption of stubble cleaners and blades were put forward. It is summarized that the importance to reduce energy consumption of stubble cleaners, to improve abrasion of stubble blades, and to combine farming machine with agricultural progress in the field.
