不同耕作方式对坡耕旱地土壤环境及小麦产量的影响
Effects of Different Tillage Measures on Soil Environment and Wheat Yield in Slopping Dry-land
摘要
Abstract
Long-term experiments analyzed the effects of no-tillage coverage and subsoiling coverage conservation tillage technologies on soil environmental factors including precipitation storage rate, infiltration, bulk density,nutrients and temperature, and wheat production. The results showed that these two technologies could improve soil nutrient content, increase soil saturated hydraulic conductivity, slow down the diurnal variation of surface temperatures, and increase the utilization of precipitafion and wheat yields. However, the application results were quite different between years. The maximum increase of wheat yields was up to 18. 89％ and 20. 87％ for the two technologies, while it was not obvious for some years. The precipitation storage rates during the rainy season were 34. 8％-77. 4％ for the no-tillage coverage technology and 38. 7％-75. 0％ for the subsoiling coverage technology. The water-use efficiencies of wheat for the no-tillage coverage measure and the subsoiling coverage measure were 1.04- 1. 82 kg/m3 and 1.07- 1. 77 kg/m3, respectively.关键词
