There is a slow speed of developing agricultural production in loess hilly gully areas ofDingxi. The major reasons that influence the speed are drought, less precipitation and soil andwater loss. Through the experiments,it was shown that the tillage measures which collect runofffor infiltrating into the hole can not only retain rainfall,but also increase the depth of infiltrationand decrease evapotranspiration of soil surface in order to improve the utilization of rainfall andsoil moisture. The objectives that preserve the soil,increase the yield and return,and utilize na-ture resources rationally can be achieved。
