摘要： 为了探讨温室黄瓜高畦双行栽培模式下，膜下沟灌适宜的灌水沟沟深，以冬丽519号黄瓜（砧木为高优亮南瓜）为试材，以常规畦沟灌溉（每次灌水量450 m³/hm²）为对照，设计了灌水沟沟深15，11，8 cm 3个处理，对应每次灌溉量300，225，150 m³/hm²，研究灌水沟规格对黄瓜产量、品质、土壤速效养分含量及灌溉水生产效率的影响。结果表明，与对照相比，3种规格灌水沟的灌水量均能满足黄瓜正常生长需求，黄瓜产量和品质与对照没有显著差异，对土壤速效养分含量也没有显著影响，但所有处理均显著地提高了灌溉水生产效率，其中秋冬茬节水率分别为27.03%，40.54%，54.05%，冬春茬节水率分别为30.20%，45.30%，60.40%。综合考虑产量与灌溉水生产效率，建议高畦双行栽培黄瓜的膜下灌水沟沟深为8 cm、单次灌水量150 m³/hm²能够满足嫁接黄瓜生产对水分的需求。

Abstract: In order to determine the optimum furrow depth of the double border deep furrow ridge for cucumber cultivation in green house by furrow irrigation under the membrane,different irrigation furrow depth,15,11,8 cm corresponding to the irrigation of 300,225,and 150 m³/ha were tested,and with the conventional furrow ridge and the irrigation of 450 m³/ha as control.The experiment investigated the yield and quality of cucumber plants Dongli 519(rootstocks:pumpkin Gaoyouliang),soil quality,and water use efficiency under the three irrigation furrow depth.The results showed that compared to the conventional irrigation,all the 3 deep furrow ridge irrigation could meet the demand of cucumber normal growth,and had no significant effect on the fruit production and quality,no obstacles on the root nutrient absorption and utilization,no influence of soil environment.In additionly,all the three irrigations significantly increased the water use efficiency.In autumn and winter crop,water-saving rates were 27.03%,40.54%,54.05% respectively;and in winter and spring crop,water-saving rates were 30.20%,45.30%,60.40% respectively.Considering yield and irrigation water use efficiency,the optimum and recommended furrow depth in deep furrow ridge mode for cucumber cultivation was 8 cm,corresponding to the irrigation of 150 m³/ha, which meet the water needs of grafting cucumber production.

Key words: Cucumber, Irrigation furrow depth, Yield, Water use efficiency
