- 摘要:
- 为提升耕地质量,实现秸秆资源循环利用,通过多年定位试验,研究了黑龙江省西部地区不同秸秆还田方式对土壤理化性状、玉米产量及机械耗能的影响。结果表明:播种前和成熟期土壤容重均表现为CK>覆盖还田>碎混还田>翻埋还田。秸秆覆盖还田可提高土壤含水量,缓解春季干旱。成熟期有机质含量表现为覆盖还田>碎混还田>翻埋还田>CK,较CK分别增加0.29,0.23和0.20 g·kg-1。覆盖还田、碎混还田和翻埋还田均能提高土壤全量养分含量,最终使玉米增产2.9%、8.3%和10.2%。油耗和作业阻力表现为翻埋还田>碎混还田>CK>覆盖还田。综合各项指标来看,可考虑将不同还田方式相结合的“轮替制”,以达到兼顾“改土壤、促增产、降能耗”的理想效果。
- Abstract:
- In order to improve the quality of cultivated land and realize the recycling of straw resources,the effects of different straw returning methods on soil physical and chemical properties,maize yield and mechanical energy consumption were studied through many years of experiments.The results showed that the soil bulk density before sowing and in mature period was CK>straw mulching returning>straw crushing returning>staw ploughing returning.Straw mulching returning could increase soil water content and alleviate spring drought.The organic matter content in mature period was as follows:straw mulching returning>straw crushing returning>straw ploughing returning>CK,compared with CK,which increased by 0.29,0.23 and 0.20 g·kg-1,respectively.Straw mulching returning,straw crushing returning and straw ploughing returning could increase the total nutrient content of soil,and ultimately increase the yield of maize by 2.9%,8.3% and 10.2%,respectively.The fuel consumption and operation resistance were as follows:straw ploughing returning>straw crushing returning>CK>straw mulching returning.Based on the indicators,we could consider the application of “rotation system” combining different returning methods to achieve the ideal effect of “improving soil,increasing yield and reducing energy consumption”.
