摘　　要：介绍了割刀切入茎秆的方向与其切割阻力和功率消耗的关系,从力学试验结果和运动几何分析两个方面说明滑切比正切省力,分析了3种切割方式切割阻力差异,确定了切割方式和切割阻力的相互关系,找到了滑切省力的原因,为以后设计各种各样的切割刀具提供了理论基础和指导方向。In this paper,the relationship of the cutting resistance,the cutting power and the direction of the cutting knife cutting into the stem was introduced.Judging from the result of the mechanical and movement geometry analysis examinations,the sliding cutting saved more labor than normal cutting.The cutting resistance difference among the three cutting ways was studied.The relationship between the cutting ways and the cutting resistance were confirmed.In the end,sliding for saving energy was analyzed and found out.The theory foundation and direction for designing different cutting knives were provided.

关 键 词：切割方式 切割阻力 切割功率 滑切 滑切角
