该文以 2006 年建立的垄作少免耕定位试验田为研究对象,分析了传统垄作和碎秆全量覆盖垄作少免耕和高留茬垄作少免耕 3 种耕作方式对土壤水分以及作物产量等的影响,以建立适合玉米垄作体系的垄作播种技术。5 a 长期定位试验结果表明,垄作少免耕种植模式能够改善土壤结构,增加土壤蓄水保墒能力,提高土壤水分利用效率;与传统垄作模式相比,碎秆全量覆盖和高留茬覆盖 2 种垄作少免耕模式的作物产量分别增加了 4.1%～10.7%和 1.9%～6.4%,土壤水分利用效率分别提高了 5.4%～10.2%和 4.1%～7.9%,其中碎秆全量覆盖垄作少免耕模式效果最为明显。研究结果可为辽宁省垄作播种模式的开展提供参考。
In this paper, the experimental plots of no-tillage and no-tillage positions were established in 2006, and the effects of three types of tillage practices, such as no-tillage and no-tillage on the soil moisture and crop yield, were analyzed. Influence, in order to establish the ridge planting system suitable for maize ridge system. 5 a long-term positioning test results show that the ridge-less no-tillage planting mode can improve the soil structure, increase soil water storage and soil moisture retention capacity and improve soil water use efficiency; compared with the traditional ridge pattern, the full coverage of culm and high stubble coverage of 2 The crop yield increased by 4.1% ~ 10.7% and 1.9% ~ 6.4%, and the soil water use efficiency increased by 5.4% ~ 10.2% and 4.1% ~ 7.9%, respectively. Plowing mode is the most obvious effect. The results can provide a reference for the planting mode of ridge planting in Liaoning Province.
