摘　　要：为解决丘陵烟区打顶环节机械化程度低,人工打顶作业劳动强度高的问题,设置了烟株打顶期顶芽茎秆剪切力学特性试验。选取秦烟96品种烟株顶芽茎秆为研究对象,通过单因素试验分析剪切刀片的刃口形状、刀片刃角和剪切速度对剪切力的影响,确定剪切刀片参数为单面刃口、刀片刃角10°、剪切速度40~60 mm/min适宜烟株顶芽茎秆的剪切。以剪切方式、刀片形状和剪切速度为影响因素,剪切力为指标,采用Design-Expert软件设置了三因素三水平正交试验。结果表明:剪切方式为滑切、刀片形状为圆弧刀、剪切速度为50 mm/min的组合,剪切烟株顶芽茎秆的剪切力较小。To improve the mechanization and reduce the labor intensity of manual topping in hilly tobacco growing areas,the shear mechanical properties of apical bud stalks during tobacco topping were investigated.Apical bud stalks of tobacco cv.Qinyan 96 were selected as the research object.The effects of cutting edge shape,cutting edge angle and shearing speed of the shearing blade on the shearing force were analyzed by a single-factor experiment.Finally,the determined parameters of shearing blade,blade edge angle and shearing speed were single edge,10°and 40-60 mm/min,respectively,which were suitable for shearing apical bud stalks.Taking the shearing mode,blade shape and shearing speed as the influencing factors and the shearing force as the index,an orthogonal experiment with three factors and three levels was set up using Design-Expert software.The results showed that when the shearing mode was sliding shear,the blade shape was an arc blade,and the shearing speed was 50 mm/min,the shearing force required to shear the apical bud stalks of tobacco plants was lower.
