对半湿润偏旱区的临汾市褐土麦田进行研究。结果表明,夏休闲期采用免耕、结合秸秆覆盖,2m土体比传统耕法多蓄水9.9~11.5mm,增产12.1%;深松结合覆盖则多蓄水25.8~34.9mm,增产14.3%。与传统耕作比较,免耕播后秸秆覆盖和深松播后秸秆覆盖的水分利用率分别提高0.26和0.29kg/mm·亩,分别增产46.9和51.8%。深松结合秸秆覆盖夏休闲,以及夏休闲麦播后连续秸秆覆盖是保蓄降雨和提高水分利用率,保证稳定增产的重要措施。
The research on the brown wheat field in Linfen City in semi-humid and semi-arid area. The results showed that the no-till combined with straw mulching in the summer leisure time, the increase of 12.1% of the yield in the 2m soil was 9.9 ~ 11.5mm, 34.9mm, an increase of 14.3%. Compared with the traditional tillage, the water use efficiency of straw mulching and straw mulching after no-till sowing increased by 0.26 and 0.29 kg / mm · mu, respectively, increased by 46.9 and 51.8% respectively. Subsoiling combined with straw cover summer leisure, and summer leisure sowing continuous straw mulching is to save the rain and improve water use efficiency, and ensure an important measure to increase production.
