Effects of Different Tillage on Soil Moisture and Temperature on Sloping Farmland in the Wind-water Erosion Crisscross Region

Studying the effects of different tillage on soil moisture and temperature in sloping farmland will provide some effective tillage measures and the credible background for reasonable tillage usage in the wind-water erosion crisscross region.The methods of positioning monitoring and Statistics were served to study the effects of conventional tillage and five conservation tillage on soil moisture and temperature in sloping farmland of the wind-water erosion crisscross region.The result shows that,straw mulching(SM),no-tillage(NT) and plastic film mulching(PM) can significantly increased soil moisture in the surface layer,and soil moisture of the deeper layer is lower in NT and higher in SM.All of the conservation tillage can keep the suitable soil temperature at the stages of extremes.Based on soil moisture and temperature,all of the conservation tillage showed positive effects,and SM is better than the other tillage.
