摘要
[目的]研究吐鲁番地区成龄葡萄滴灌水分利用率。[方法]采用对比法,共设6个处理,研究吐鲁番地区成龄葡萄滴灌条件下产量、边际产量、水分利用与耗水量效率之间的关系,并拟合了葡萄产量、水分利用效率与全生育期耗水之间的关系。[结果]葡萄水分利用效率和产量与耗水量均呈二次抛物线关系,吐鲁番地区成龄葡萄合理耗水区间为783-905 mm。[结论]葡萄产量、水分利用效率与全生育期耗水量之间的相关性较高,可定量描述吐鲁番地区成龄葡萄滴灌条件下葡萄产量、水分利用效率与全生育期耗水的关系。
[Objective] To study water use efficiency of drip irrigation for mature grapes in Turpan.[Method] Comparison method was used to analyze the relation between yield,marginal yield,water use,and water consumption efficiency of drip irrigation for mature grapes in Turpan. Besides,the relation between grape yield,water use efficiency and water consumption in the whole growth period was fitted.[Result]The water use efficiency of grape and the yield,water consumption presents quadratic parabola relationship,the reasonable water consumption range is 783-905 mm for mature grapes in Turpan.[Conclusion] There is high correlation between grape yield,water use efficiency and water consumption in the whole growth period. It is able to make a quantitative description of the relation between grape yield,water use efficiency and water consumption in the whole growth period in drip irrigation condition for mature grapes in Turpan.
