摘要
设计制作了几种弯曲型深松部件 ,通过室内大型土槽耕作试验 ,测定了各种深松部件耕作以后土壤的宏观扰动轮廓和耕作阻力 ,对于土壤的宏观扰动轮廓给出了定量化的图形表达方式 。
Several types of curved subsoiler shapes are designed and founded,and the macroscopical disturbing profile of soil after subsoiling and these subsoilers'working resistance are measured with a big laboratory soil bin, the manner of graphics expression about the macroscopical disturbing profile of soil after subsoiling is quantificationally given,and the relation between the cultivation resistance and the macroscopical disturbing profile of soil after subsoiling is analyzed
