试验结果表明，根茬含水率愈高，剪切力愈小，根茬含水率与剪切力近似为二次曲线关系；刀片剪切速度愈快，剪切力愈小；凸曲线、斜线、凹曲线和直线四种不同的刀刃曲线对整株根茬剪切力依此由小到大，凸曲线和斜线剪切时有一定程度的滑切作用，所以剪切力相比较小，当根茬含水率为48 . 2 ，剪切速度500mm min时，与其他三种曲线相比凸曲线型刀刃的剪切力依次分别减少了7 . 2 、 22和29 ；对根茬中部、梢部和根部的剪切力，在相同试验条件下，径向中部最大，比梢部，轴向根部和根部茎秆所需剪切力分别增加32 、 45和111 ；当含水率为48 . 2 ，刀片的剪切速度为500mm min时，一年一熟玉米根茬比一年两熟的玉米根茬剪切力增大37 。 | | 6. | The experiment calculate , arranges and analyzed the present situation , the main problems and the developing tendency of the protecting farming of two crops a year in the high yield field in longkou city , and this experiment raised the best protecting farming system which can improve the grain growing of the high yield field , the results are as follows : 1
