摘　　要：针对目前新疆地区大力发展的棉花膜下软管灌技术，在塔里木盆地阿瓦提丰收灌区进行了田间对比试验研究。结果表明，毛管布置方式一膜三管在灌水均匀度、棉花产量等方面都优于一膜二管的布置方式；膜下软管灌棉花生育期内适宜灌溉定额为3600－4200m^2／hm^2，灌水次数为10次；膜下软管灌技术灌水均匀，是一项较好的灌水技术。In the paper, technique of self-pressure hose irrigation under membrane for cotton, which is now extensively applied in the cotton fields of Xinjiang, is preliminarily studied. The field contrast experiment is carried out through controls of the different irrigation quotas and different irrigation frequencies during whole growth stages of cotton in Awati＇s Fengshou irrigation district in Tarim Basin. The results show that, under the same irrigation conditions： ten times and quotas 3600-4200 m3/hm^2, the mode of arrangement of three-hose line is superior to that of two-hose line in irrigation uniformity, yield and other aspects of cotton production, and that hose irrigation under membrane uniform is a better irrigation technique.
