Abstract: Apricot is a sort of the good trees to use in controlling and exploiting sloping field whose slope degree is larger than 25 degree on loess hilly-gully region of Shaanbei. We have researched the relation between water & fertility of soil and high yield & fine quality of apricot on sloping field by the ways as water conservation project, raising the amount of using fertilizer and so on. The results are as follows: the water content in soil increases dearly with building big tunnel like fish scales and the water content in soil of root region decreases with raising the amount of fertilizer for apricot on sloping field. The absorption and usage of application of apricot to water and fertilizer increases by combining building big tunnel like fish scales with raising the amount of fertilizers, the transpiration intensity and chlorophyll synthetic of leaves rises, the yield increases and the quality rises too. As a result, we think it is one of the most effective ways to get high yield and fine quality of apricot, to build water conservation project and raise the amount of fertilizer on arid and unproductive sloping field with serious water and soil erosion.
