摘　　要：为了研究新型根渗管的使用技术与应用效果,在阿克苏地区红枣园开展了为期3年的试验研究。结果表明:采用"一行两管"的布置模式,本新型根渗管能够很好地满足树龄为10年左右枣树的灌水需求;并且与常规滴灌相比所需运行压力小,运行成本可降低50%～80%,每年可节省投资1 271元/hm2;比起常规漫灌其水分利用率高,就种植红枣而言,农民每年可增加收入42 640元/hm2。In order to research the using technic and application effect of the new type of root-seepage-pipe, the experiment performed in the jujube orchard of Aksu prefecture for 3 years. The results revealed that the pipe can well meet.the tree of 10 years or so with ＂a line of two pipe＂ patterrL Compared with conventional drip irrigation the operating pressure of root-seepage irrigation is lower and its operating costs can reduce 50~80~//0 as well as its investment can saving 1 271 yuan/hm2 every year. Compared with conven- tional flooding water application efficiency of root-seepage irrigation is higher, and the income of farmer can increase 42 640 yuan/hm2 every year for planting red jujube.
