通过“埋块试验”探讨了犁体宽深比和耕深对翻土覆盖性能的影响,证明了窄幅深耕犁的翻土覆盖性能能满足农艺要求。发现犁的宽深比还影响土垡在行驶方向上的位移距离,用窄幅深耕犁时土垡在行驶方向上的位移距离明显小于普通铧式犁,这很可能是窄幅深耕犁比阻降低的主要因素之一。
The effect of plow width-depth ratio and tillage depth on tilling overlay performance was discussed by “buried-block test”, and it was proved that tilling overlay performance of narrow tillage plow can meet agronomic requirements. It was found that the plow width-depth ratio also affected the soil moving in the direction of the displacement of the distance, with a narrow deep-plowing when soil 垡 in the direction of the displacement is significantly smaller than ordinary plow, which is likely to narrow plow deep plow resistance One of the main factors to reduce.
