中文摘要：
研究间接地下滴灌条件下不同供水下限对甜瓜植株性状、品质和产量的影响,并以常规沟灌为对照。在生长初期,甜瓜的株高、茎粗、叶片数和叶面积等植株性状差异较小,随着时间的推移,各性状差异逐渐增大,中水和高水处理下的植株长势较好;低水处理下的甜瓜的可溶性总糖含量最高,中水处理下的甜瓜的可溶性固形物、可溶性蛋白和Vc的含量均最高;沟灌可以提高单果质量和小区产量,但水分利用效率（WUE）最低,中水处理在不显著降低单果质量和小区产量的前提下可以提高WUE。综合考虑甜瓜植株长势、品质、产量和WUE,中水处理是间接地下滴灌条件下最佳的供水模式。
英文摘要：
Effects of different water elevations on plant physiological characteristics,quality and yield of greenhouse muskmelon in indirect subsurface irrigation was studied,compared with regular furrow irrigation method.The difference of plant height,stem diameter,No.of leaves and leaves area in different treatments is insignificant in the early development stage,and significant in the later stage.The development of plant is predominant in moderate and high water treatments.The pulp sugar content in low water treatment and the soluble solid,soluble protein and Vc content in moderate water treatment is very high.Furrow irrigation can improve the fresh weight and the area production,but with WUE decreased;the moderate water treatment can improve WUE without the decrease of the fresh weight and the area production significantly.Moderate water treatment in indirect subsurface irrigation is the best water supply model within plant development,quality,yield and WUE considered.
