| 摘 要： | 目的]为同时满足新疆枣棉间作系统中枣与棉花的需水规律,不影响棉花产量的情况下,提高枣产量.在棉花播种至开花前不需灌水的情况下,对间作地枣树进行补水,揭示枣与棉花的产量、效益差异,以期为新疆枣棉间作系统的水分调控提供理论依据.方法]分别于枣树萌芽期(4月下旬)和初花期(5月下旬)对枣树行补水,设置试验方案为补水1次、2次、对照(不补水),重复3次.生长季节定期测定枣树生长量,枣果成熟期测定标准枝的坐果数、单果重、产量,并测算间作棉花的单产.结果]补水1次与2次后,枣树新稍增长量明显高于对照,灌水次数之间差异不显著;补2次水的坐果数略低于补1次和对照,但单果重和产量却显著高于其他2个处理;不同处理间棉花产量和品质无显著差异.结论]枣棉间作系统中,应对枣树的萌芽期和初花期分别补水1次.这对提高枣树的生长、结实及产量非常有利,而对棉花的生长和产量没有影响.

| Abstract: | Objective]To meet the requirements of water for jujube and cotton at the same time in the jujube-cotton intercropping system,and the yield of cotton,increase the yield of Jujube.A supplementary irrigation experiment for jujube was conducted from the cotton seeding to blooming without irrigation to reveal differences of yield and benefit between jujube and cotton to provide theoretical basis for water regulation in jujube-cotton intercropping system.Method]The supplementary irrigation was conducted for jujube at the sprouting stage (the last ten-day period of Apr.) and at the initial flower stage (the last ten-day period of May),the supplementary irrigation experiment was designed as follows:once,twice,CK (Supplementary irrigation was not be carried out)repeated three times.The fruit set percentage,weight per fruit,yield of jujube and cotton in intercropping system during the growth stage and mature stage were determined.Result]after once and twice supplementary irrigation the growth rate of new treetops of jujube were significantly higher than that of CK.The stem growth increment of different treatments kept steady increasing speed at all times,there weren’t significant diversity among them.The fruit setting percentage of twice supplementary irrigation evidently were lower than those of once irrigation and CK,but the single fruit weight and yield were more than that of other treatments,and there were no differences between once irrigation and CK.The yield and quality of cotton per mu had not evident differences compared with those of other treatments.Conclusion]In the jujube-cotton intercropping system,it should be given by once supplementary irrigation at budding stage and at first flower stage.It is necessary for growing,bearing and increasing yield of jujube. |
