摘 要：
Aiming at solving the problem of low afforestation survival rate caused by little rainfall amount and difficult filing-irrigation in loess hilly areas of northern Shaanxi, a new type of easy dripping irrigation system is designed and tested. The result showed that the system can increase the survival rate of the economical forests such as Chinese jujube, apricot and increase by 52.3% and 2.2% respectively; and in the meanltime, little soil moisture was lost by evaporation due to the deep layer irrigation in this system and the soil surface is not hardened .The yield of jujube and apricot increased by 43.3% and 35.5% compared with the conventional hole irrigation.
