摘　　要：对哈密地区葡萄大枣滴灌工程作一简单介绍,在此条件下分别铺设滴灌毛管:一行一管,一行两管,一行三管,一行四管等4种方案[1,2]。通过计算各种方案单位面积的投入费用和对各种处理下葡萄、大枣生长量和产量效益分析,最终得出葡萄园4种毛管铺设方式下滴灌系统管带及水电的单位面积投入分别为:1 245、2 400、3 480、4 545元/hm2,与传统的沟灌4 950元/hm2的投入而产量为32.25t/hm2相比,其产量分别为27.9、34.95、36.3、37.8t/hm2,选定一行三管的毛管铺设方式最为经济合理。大枣园4种毛管铺设方式下滴灌系统管带及水电的单位面积投入分别为:1 080、1 860、2 565、3 375元/hm2,与传统的沟灌3 225元/hm2的投入而产量为12t/hm2相比,其产量分别为10.35、13.95、14.4、20.55t/hm2,选定一行四管的毛管铺设方式最为经济合理。This paper first briefly introduces the drip irrigation systems for grape and jujube in Hami region.Based on it,four schemes for capillary pipe layout are proposed,including one pipe,two pipes,three pipes and four pipes per row.Through the calculation of the unit area investment and the growth and yield benefit of grape and jujube of each treatment,it is finally found that for vineyard,the unit area investments of drip irrigation pipe band and hydropower charge of the four schemes are 1 245,2 400,3 480,4 545 Yuan per hectare,while the yields are 27.9,34.95,36.3 and 37.8 t per hectare,respectively.According to the comparison with the traditional furrow irrigation,in which the investment is 4 950 Yuan per hectare and the yield is 32.25 t per hectare,the capillary pipe layout scheme with three pipes per row is selected as the most economical and reasonable one.While for Jujube garden,the unit area investments of drip irrigation pipe band and hydropower charge of the four schemes are 1 080,1 860,2 565,3 375 Yuan per hectare,while the yields are 10.35,13.95,14.4 and 20.55 t per hectare,respectively.According to the comparison with the traditional furrow irrigation,in which the investment is 3 225 Yuan per hectare and the yield is 12 t per hectare,the capillary pipe layout scheme with four pipes per row is selected as the most economical and reasonable one.
