The test results in the no - tillage fields with corn rootstalks shown that the sample machine has a good ability to cut and dig corn rootstalks only in the seed beds so that the new no tillage planter can create a good condition of seed bed and have lower power consume . 2 system experiment is conducted to investigate the mechanical properties of rootstalks and soil rootstalk composite . the experiment results include : ? he maximum cutting force decreased exponentially with increasing cutting speed and the moisture contents of rootstalks 通过对新型免耕播种机的田间生产试验,证明了切挖处理播种带玉米根茬原理可行,所开发的机具结构新颖,具有创新性;该机不但能创造无根茬的良好种床条件,有利于种子生长发芽,而且不需大量粉碎根茬,因而扰土量少、整机消耗动力小、破茬入土能力强,有利于充分发挥保护性耕作的优势。
