摘要
在旱地壤土条件下，通过对犁铧磨损与犁铧性能间关系的试验表明，当犁铧铧尖磨损量达５０ｍｍ时，土壤作用于犁体的耕作阻力增大４９．２％，燃油消耗增加２７％，耕深减少４５％，入士行程增长１．５倍，耕深稳定性也显著变差。
The testing relation between share
wear and plow tillage performances inthe case of loams in rainfed farmland shows that when the
waer of plow share tip reach-es 50mm,the tillage resistance acting upon plow body can increase
by 49.2%, fuel con-somption increases by 27%,tillage depth is reduced by 45%, the distance going
intoearth increases 1.5 times as much,and the stability of tillage depth varies significantly.
