| 摘 要： | 通过对土壤容重、总孔隙度、含水量、田间持水量及玉米产量的测定和分析,研究一次性施肥条件下深松-旋耕、深松-免耕、常规旋耕和免耕不同耕作方式对土壤物理性状及玉米产量的影响。结果表明,不同耕作方式对土壤容重和土壤含水量的影响效果为深松-旋耕深松-免耕常规旋耕免耕;对土壤持水量的影响效果为深松-免耕常规旋耕深松-旋耕免耕;对玉米产量的影响效果为深松-免耕免耕常规旋耕深松-旋耕,深松-免耕和免耕分别与深松旋耕和常规旋耕的产量差异达极显著水平,深松-免耕较常规旋耕增产15.68%,产量高达6 829.73 kg/hm2。

| Abstract: | By the mensuration and analysis of soil bulk density, soil total porosity, soil moisture content, soil moisture capacity and maize yield, the effects of subsoiling and rotary tilling, subsoiling and no-tillage, conventional rotary tillage and no- tillage on soil physical characters and maize yield through field experiments in a single fertil- ization were researched. The results showed that the effects of tillage methods on the soil bulk density and soil mois- ture content were different, with the order of subsoiling and rotary tilling, subsoiling and no-tillage, conventional ro- tary tillage and no-tillage. The effects of tillage methods on the soil total porosity were different, with the order of subsoiling and no-tillage, no-tillage, subsoiling and rotary tilling and conventional rotary tillage. The effects of till- age methods on the soil moisture capacity were different, with the order of subsoiling and no-tillage, conventional ro- tary tillage, subsoiling and rotary tilling and no-tillage. Finally the tillage managements have a great effect on maize yield, with order of subsoiling and no-tillage, no-tillage, conventional rotary tillage, subsoiling and rotary tilling. There was a significant difference between subsoiling and no-tillage, no-tillage and conventional rotary tillage, sub- soiling and rotary tilling. The production of subsoiling and no-tillage, increased 15.68% than conventional rotary tillage, achieved 6 829.73 kilograms per hectare. |
