Impact of conservation tillage on soil wind erosion
保护性耕作对土壤风蚀的影响

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...
