[目的]探究滴灌条件下适宜葡萄生长并有利于提高葡萄产量和品质的水肥协同模式.[万法]以多年生"无核白"葡萄为供试对象,设置3个灌水水平(W1:10 950 m3/hm2、W2:9 150 m3/hm2、W3:7 800 m3/hm2)和3个施氮水平(Nl:750kg/hm2、N2:450 kg/hm2、N3:300kg/hm2),共计9个处理,每个处理重复3次,开展田间水肥协同试验,研究不同水肥耦合模式对葡萄果粒生长发育、产量及品质的影响.[结果]W2N2处理下葡萄外观品质、百粒质量、产量、可溶性固形物量及硬度均优于其他处理,而W2N3处理的固酸比最优,但与 W2N2处理差异不显著,W1N1处理葡萄维生素C量最优,并与其他各处理差异显著.[结论]综合考虑葡萄各项指标,W2N2处理(灌水量为9 150 m3/hm2、施氮量为450 kg/hm2)为最优的水肥耦合模式.通过建立水肥输入量与葡萄产量的二元二次回归模型,确定高产的水、肥最适宜用量分别为9 723 m3/hm2、557kg/hm2,目标产量为38636.53kg/hm2.
