通过4年多的研究,表明稻麦秸秆还田能有效地改善土壤理化性能和促进作物产量的提高。留高桩还田能有效地改善土壤物理性能,墒沟埋草能有效地提高土壤有机质的含量,麦田覆草能提高表层土壤的湿度和温度。几种秸秆还田方式中,以留高桩还田方法简便、效果最好;秸秆还田量以2250kg/hm2最为适宜,配合施用标准氮肥95kg/hm2。
After more than four years of research, it has been concluded that returning straw to wheat straw can effectively improve soil physical and chemical properties and increase crop yield. Remaining piles with high pile can effectively improve the physical properties of the soil. The ditching can effectively improve the content of soil organic matter, and the straw mulch can improve the soil moisture and temperature. In some straw returning methods, the method of returning tall piles to field was simple and the effect was the best. The straw returning quantity was the most suitable for 2250kg / hm2, and the standard nitrogen fertilizer was 95kg / hm2.
