摘　　要：环塔里木盆地具有发展红枣种植的独特优势,也是对红枣节水灌溉技术需求大的地区。采用干旱区最常用的滴灌、低压软管灌、微喷灌、沟灌4种灌水技术进行田间试验,从红枣的叶温、地温、坐果率、产量、品质、气候特点和田间管理等几个方面进行了比较。结果表明滴灌在叶温、品质、适应气候、田间管理等主要的方面最优,微灌在坐果率和产量方面最优;干旱区幼龄红枣最适宜的灌溉技术是滴灌+花期微喷。Surrounding Tarim basin has particularly advantages of developing Chinese Jujube planting,where water saving irrigation technique is urgently needed too.Field test are conducted with drip irrigation,micro-sprinkler irrigation,low-pressure penstock irrigation and channel irrigation.The four irrigation modes are compared from the aspects of the leaf temperature,ground temperature,yield,fruit-setting,yield,fruit quality and climate,etc.The results showed that the drip irrigation mode is the best in the leaf temperature,fruit quality,climate adjustability and field management,etc.While the micro-sprinkler irrigation mode is the best in the fruit-setting,yield of sprinkle irrigation.The best irrigation mode is drip irrigation in the whole growth period and sprinkle irrigation in the florescence period.
