一个连续２ 年的田间耕作试验在夏玉米生长期内完成，分析对比３ 种不同耕作方式对土壤水动态变化过程及对作物产量的影响。耕作扰动对土壤水动态变化的影响是明显的，夏玉米生长初期免耕下的表层土壤持有较高的水分，这归因于土壤非耕扰动、冬小麦残茬覆盖以及耕层土壤孔隙尺度分布的变化；另一方面，深松土壤受到耕作活动的强烈干扰，苗期耕层土壤蓄水明显小于传统耕作。耕作方式对土壤水差异的影响伴随着作物的生长发育过程显著减弱。深松耕作对作物根系生长发育状况及作物增产效果的作用是十分显见的。
A two-year field experiment was completed during the summer maize growing season. The effects of three different tillage practices on soil water dynamics and crop yield were compared. The effect of tillage disturbance on soil water dynamic change is obvious. No tillage topsoil in summer maize holds high water content, which is attributed to soil non-tillage disturbance, winter wheat stubble coverage and topsoil pore size distribution On the other hand, the subsoiling soil was strongly disturbed by tillage activities, and the soil water storage at the seedling stage was significantly less than that of the conventional tillage. The impact of tillage on soil water differences is accompanied by a significant reduction in crop growth and development. The effect of deep-plowing on crop growth and development and crop yield increase is very obvious.
