| 摘 要： | 保护性耕作能够有效减少农田土壤风蚀.通过室内风洞模拟试验,研究秸秆覆盖、留茬和垄作3种保护性耕作措施对黄土高原北部农田土壤风蚀的影响.结果表明:1)秸秆覆盖和留茬能有效降低土壤风蚀速率,秸秆覆盖量为4 210 kg/hm2时土壤风蚀速率最小,与对照相比减少62.8%;垄作在低风速下能够降低土壤风蚀率,垄向与风向垂直时降... |

| Abstract: | Conservation tillage could reduce soil wind erosion effectively on farmland.An experiment of soil wind erosion on farmland in northern Loess Plateau was designed with wind tunnel tests under different conservation treatments including straw mulch,stubble and ridge tillage.The results indicated that straw mulch and stubble could reduce the soil wind erosion rate,and the soil wind erosion rate under straw mulch with 4 210 kg/hm2 was decreased by 62.8% compared with CK(no conservation treatment),which was less... |
