基于田间试验,研究不同耕作方式对豫东雨养区土壤水分调控效果。试验结果表明,秸秆覆盖还田免耕处理,对夏玉米生长主要根层的土壤水分的调控能力作用较为显著,在连续干旱1个月后(播后30d),0～60cm土壤含水率分别比深耕和深松高19.7%、4.5%,夏玉米单株干物质累积量、群体叶面积指数指标均优于其他2个处理,产量和水分利用效率比深耕处理提高31.2%和16%。 Based on field experiments, the effects of different tillage methods on soil moisture regulation in rainfed areas of eastern Henan were studied. The results showed that straw mulching with no-tillage treatment had a significant effect on the regulation of soil water content in the main root layer of summer maize. After 1 month of continuous drought (30 days after sowing), the soil water content of 0-60 cm The indexes of deep-plowing and deep-subsoiling 19.7%, 4.5%, summer maize per plant dry matter accumulation, population leaf area index were better than the other two treatments, the yield and water use efficiency increased 31.2% and 16% than the deep-plowing treatment.
