Abstract:

The technique that digging holes and covering film in big fish-scale pits and drip irrigation under film can solve the problems about the low survival percentage, the slow growth and the late development of the cash trees on the arid slope-land planted on the hilly and gully area of loess planteau. The results showed that the apricot's percentage of survival increased to 96%, and the jujube's percentage of survival increased to 92%. The fish-scale pit collected runoff so as to increase the utilization ratio of rainfall, about to 42.5%, moreover, drip irrigation under film with saving water bag refrain the soil from compactness, and decreased the evaporation of soil, which increased the yield of apricot and jujube respectively 10.32% and 19.61% comparing with control.
