摘　　要：[Objective] This study was to investigate the effects of different irrigation amount on water consumption and water use efficiency of greenhouse cucumber.[Method]Under the condition of drip irrigation with different water amounts in sunlight greenhouse of the arid areas in Ningxia,the soil water was measured and the water consumption of crop was calculated.[Result]When irrigation amount was 563 mm,the water consumption as a whole gradually increased with the delay of growth period,reached peak during the thriving stage of fruit setting,and then gradually declined;in each treatment,the daily water consumption increased with the increasing of irrigation amount during each growth period.However,the consumption of soil moisture reduced with the significant increase of irrigation.563 mm of irrigation amount could meet the water requirements of cucumber and began to add water to soil,and water utilization efficiency could reach 33.4 kg/m3.[Conclusion]The research had provided theoretical basis for water management in the production process of greenhouse cucumber.[目的]研究不同灌水量对日光温室温控黄瓜耗水规律及水分利用效率的影响。[方法]在宁夏干旱区日光温室膜下滴灌条件下,研究了不同灌水量对日光温室黄瓜耗水规律和土壤水分利用效率的影响。[结果]灌水量为563不得mm时,耗水强度整体随着生育期的延后逐渐增大,在结果盛期达到最大,随后逐渐下降,在各个生育期各处理日耗水强度随灌水量的增加而增加;而土壤水分的消耗则随着灌水量的增加而明显减少,灌水量达到563mm时完全能满足黄瓜水分需求,并开始向土壤补充水分,且水分利用率达到33.4kg/m3。[结论]该研究为温室黄瓜生产生产的水分管理提供了依据。
