    試驗結果表明，根茬含水率愈高，剪切力愈小，根茬含水率與剪切力近似為二次曲線關系；刀片剪切速度愈快，剪切力愈小；凸曲線、斜線、凹曲線和直線四種不同的刀刃曲線對整株根茬剪切力依此由小到大，凸曲線和斜線剪切時有一定程度的滑切作用，所以剪切力相比較小，當根茬含水率為48 . 2 ，剪切速度500mm min時，與其他三種曲線相比凸曲線型刀刃的剪切力依次分別減少了7 . 2 、 22和29 ；對根茬中部、梢部和根部的剪切力，在相同試驗條件下，徑向中部最大，比梢部，軸向根部和根部莖稈所需剪切力分別增加32 、 45和111 ；當含水率為48 . 2 ，刀片的剪切速度為500mm min時，一年一熟玉米根茬比一年兩熟的玉米根茬剪切力增大37 。
