| 摘 要： | 秸秆覆盖对旱作麦田水分及产量影响的研究结果表明,春小麦播种后立即覆盖秸秆有明显的保墒、蓄水作用,秸秆覆盖后苗期、拔节期、收获后土壤0～40 cm耕层的水分含量分别比露地提高1.6～13.3、7.8～32.8、4.1～8.6 g/kg;折合产量比露地增产12.47%～29.63%,以覆盖秸秆6 000 kg/hm2的处理增产效果最好,折合产量2 459.04 kg/hm2,比对照增产29.63%.

| Abstract: | The results that the straw mulch has obvious effects on the soil-moisture and seed yield in the arid area showed that it could store water and keep the soil moisture after the spring wheat had been sowed seeds. After wheat was straw mulch, soil moisture had been respectively increased 1.6-13.3,7.8-32.8 and 4. 1-8.6 g/kg in the 0-40 cm depth than not covered plot in the seedling stage, jointing stage and after harvest. Converted it into the output, the production had increased 12.47%-29.63% than the dew place. Among of them, the 6 000 kg/hm^2 of straw mulch was best in water-saving and increasing yield, the yield was 2 459.04 kg/hm^2,it has increased 29.63% than CK. |
