| 摘 要： | 风蚀是造成土壤流失、环境污染的重要原因之一。通过分析免耕覆盖、深松覆盖、耙茬覆盖和传统耕作4种不同处理方式对风蚀的影响,结果表明:不同处理方式对土壤风蚀的影响不同。土壤含水量的变化趋势是:免耕覆盖>深松覆盖>耙茬覆盖>传统耕作;地表粗糙度的变化趋势为:免耕覆盖>深松覆盖>耙地覆盖>传统耕;耙茬覆盖、深松覆盖和免耕覆盖的抗风蚀能力要优于传统耕作。

| Abstract: | Eolation is an important reason of soil spillage and environmental pollution. Effects of four kinds processing treatment ways such as zero tillage-covering, deep-pulverize covering, harrowing stubble covering and traditional cultivation on eolation were investigated in the paper. Results showed different treatment way could affect eolation differently, the trend of content of water in soil and roughness of soil surface was zero tillage-covering>deep-pulverize covering> harrowing stubble covering>traditional cultivation. Anti-eolation abilities of tillage-covering, deep-pulverize covering, harrowing stubble covering were better than traditional cultivation. |
