摘　　要：割前脱粒主要强调的是先摘脱谷粒后切割茎秆的工艺方法。分析收获机械脱粒装置的工作原理,对割前脱粒收获机械脱粒部位工作过程中的物理现象进行一定的分析,简要阐述割前脱粒收获机械的研究现状和未来发展战略。Threshing of before-cutting mainly enphasize the process which firstly thresh the grain from crop and then cut the stem. Analyse the working principle of harvester＇s threshing device and physical phenomenon of threshing-parts in working process of threshing of before-cutting harvester. Briefly describe threshing of before-cutting harvester which research at present and the trend of development.
