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。
Abstract
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.Be-sides,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 consump-tion in the whole growth period in drip irrigation condition for mature grapes in Turpan.
