| 中文摘要: |
| 通过对地膜、秸秆和液膜三种覆盖栽培模式对冬小麦土壤水分动态的影响进行分析,结果表明,地膜覆盖能显著提高产量,增产8.32%,增产效果优于秸秆覆盖和液膜覆盖;地膜覆盖和液膜覆盖返青期有增温保墒作用,耕层土壤含水量较对照增加4.4%和3.0%;秸秆覆盖在冬小麦的关键生育期保墒效果好,返青期和抽穗期0~100 cm贮水量较对照高15.2 mm和9.8 mm,前期的低温效应,对冬小麦生长有抑制作用,但后期表现出优势。不同覆盖可提高水分利用效率,秸秆覆盖有利于豫西地区土壤的培肥和可持续利用。 |

| This paper analyzed effect of mulching on the growth of winter wheat and the soil water dynamics with plastic film,straw mulching and black liquid film.The results indicated that the significant effect of the plastic film on yield factors in these film,increased 8.32%.Plastic film and liquid film could increase temperature and soil moisture in returning green stage,0～20 cm soil water content increased 4.4% and 3.0% respectively.Straw mulching increase soil moisture in key growth stage,0～100 cm soil water storage increased 15.2 mm and 9.8 mm in returning green stage and heading stage,as the inhabited for winter wheat by low temperature efficiency in early stage,but shows better in late stage.Different mulching could increase the water use efficiency.The best choice is straw mulching,which is good for soil fertilizer and soil sustainable use. |
