摘　　要：日光温室生产中膜下滴灌技术的应用面积在不断扩大，但生产中仍依据传统的灌水模式或未覆膜时的滴灌制度。然而膜下滴灌减少了棵间蒸发损失，增强了有效蒸腾作用，使作物需水规律发生了变化，所以膜下滴灌不能完全套用传统的灌溉模式。基于上述原因，对膜下滴灌条件下日光温室黄瓜的灌溉制度进行了试验研究。分析了不同水分处理对黄瓜株高、茎粗、叶面积指数等形态指标的影响，以及对产量、品质等的影响。分析结果表明，为实现日光温室黄瓜生产获得高产、优质及节水的目标，日光温室夏黄瓜在膜下滴灌条件下，结果期理想的耗水量应为120mm左右，日耗水强度为3．04～4．68mm。每隔4～5d灌1次水，灌水定额为15mm。以上试验所得指标可作为日光温室黄瓜生产控制水分及滴灌系统设计的参考依据。Even though the application area of mulch drip irrigation technique in solar greenhouse is expanding, the traditional irrigation methods or drip irrigation regime without mulch are dominant in production. Drip irrigation with mulch reduces evaporation loss among plants, enhances effective transpiration and changes water requirement rules, so traditional irrigation schedule cannot be applied in solar greenhouse. For these reasons, irrigation scheduling of cucumber was researched under mulch drip irrigation in solar greenhouse in this paper. The effects of different water treatments on plant height, stem diameter, leaf area index （LAI）, yield and quality of cucumber were studied. The result proved that in order to reach the aims of high yield, good quality and water saving, the ideal water consumption is 120 mm and daily water consumption is 3. 04-4. 68 mm at the growing stages, thus it is irrigated once every 4-5 days with irrigation quota of 15 mm. These are reference basis not only for water control of cucumber in solar greenhouse, but also for design of drip irrigation system.
