深耕松土作业常常意味着消耗大量的功率和燃料,并增加拖拉机的磨损。但这并不等于完成的有用功是与机具的耗费和磨损成比例。深耕松土性能确切的评价,应该用土壤有用的扰动范围和碎裂效果与所需的功率或牵引力之间的关系来作出。现就与此有关的方面,作简单叙述。深耕松土铲齿用于深耕松土的铲齿,可概略地分为 Tillage operations often mean loosening large amounts of power and fuel and increasing tractor wear. But this does not mean that the useful work done is proportional to the cost and wear of the implement. The exact evaluation of deep plowed soil behavior should be made using the range of perturbation and the effect of fragmentation on the soil and the required power or traction. Here is a brief account of the relevant aspects. Tillage loose soil shovel tooth Tillage for deep plowing loose soil can be roughly divided into
