中文摘要	在新疆阿克苏地区进行了膜下滴灌条件下水肥耦合对红枣产量和品质影响的田间试验，利用果树试验数理统计方法，建立了红枣产量的水肥耦合模型：y=-12670.96+40.54I+19.33F-0.0349I~2-0.00893F~2-0.000043I·F.结果表明：在膜下滴灌条件下，红枣产量与灌水量和施肥量都呈二次抛物线关系，合理的水肥投入对红枣具有增产效果，水肥耦合为协同效应；但过多的水肥投入并不利于红枣增产，水肥耦合为拮抗效应.水肥耦合效应对红枣品质的影响不明显.红枣获得单位最高产量时，全生育期的灌水量和施肥量分别为579.7m~3/hm~2、1081.2kg/hm~2(N 254.29kg/hm~2，P_2O_5190.64kg/hm~2，K_2O 81.04kg/hm~2)。
英文摘要	The effects of water-fertilizer coupling on jujube yield and fruit quality under drip irrigation with plastic film were studied by filed test in Akesu area.With the means of mathematic statistic for fruit tree trial, the mathematical model for jujube yield and its main affecting factors water and fertilizer was established, which was as y=-12670.96+40.54I+19.33F-0.0349I~2-0.00893F~2-0.000043I·F.The results showed that under drip irrigation with plastic film the relationships between jujube yield and the irrigation norm or fertilizer were quadratic parabola.Appropriate water and fertilizer supply could improve the effect of increasing jujube yield, and the coupling effect of water and fertilizer was cooperation.But when water and fertilizer supply was excessive, the jujube yield decreased, and the coupling effect of water and fertilizer was antagonism.The effect of water-fertilizer coupling on fruit quality was not significant. When jujube yield per hectare reach the top, the best pattern was 579.7m~3/hm~2 of irrigation and 1081.2 kg/hm~2 of fertilizer, which included N 254.29kg/hm~2, P_2O_5190.64kg/hm~2, K_2O 81.04kg/hm~2.
