摘　　要：新疆天山南北坡冲积扇扇缘分布着大量的砾质戈壁,保水保肥性极差,常规造林成活率、保存率低,灌溉投入高,采用保水剂蘸根、坑施,对提高造林成活率起到了积极作用。试验结果表明:在滴灌条件下,采用保水剂造林,灌溉定额4 500 m3.hm-2是经济合理的;幼树新造林地,合理的保水剂用量为60 g.株-1。Lots of gravel Gobi have distributed on the edge of alluvial fan of north and south facing slope in Xinjiang. The water and nutrient preserving capability were extremely poor, The general afforestation sin-rival rate and preserving rate were lower. The irrigation plunge was high. Using water retaining agent to wet roots and fertilize in pit, active role was played in increasing survival rate. Research showed that irrigation quota under irrigation condition by using water retaining agent was economical and reasonable . Optimal amount of water retaining agent was 60 g · tree^-1 in young sapling in new planting site.
