| 摘 要： | 在国家粮食丰产工程深州试验区,进行了小麦秸秆覆盖夏玉米的试验研究。结果表明,秸秆覆盖条件下的土壤导水率较高,降雨入渗快,土壤含水率较高。秸秆覆盖还可以有效降低土壤温度,尤其在苗期与对照差异显著,且土壤温度日变化平缓。由于水热状况良好,秸秆覆盖下作物长势良好,叶面积和株高都高于对照。

| Abstract: | The experiment of mulching was conducted at the Shenzhou experimental area. The results found water transmissibility coefficient of mulched ground was larger than the contrast and rainfall infiltrated into soil quickly. Mulching could not only effectively reduce soil temperature, especially at the earlier stage, but also could make daily range smaller and create a better condition for maize growth, its leaf area and height being larger than the contrast. |
