[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。
[Objective] The research aimed to study the effects of different irrigation amount on water consumption and water use efficiency of temperature-controlled cucumber in sunlight greenhouse. [Method] Under the condition of drip irrigation under sunlit greenhouses in Ningxia arid area, the effects of different irrigation amount on cucumber water consumption and soil water use efficiency were studied. [Result] When the irrigation amount was 563 mm, the water consumption intensity increased gradually with the delay of growth period and reached the maximum during the peak period of the result, then decreased gradually. The water consumption intensity of each treatment day in each growth period varied with the irrigation amount While the soil water consumption decreased significantly with the increase of irrigation water. When the irrigation water reached 563mm, it could fully meet the water requirement of cucumber and began to replenish the soil with water, and the water use efficiency reached 33.4kg / m3. [Conclusion] The study provided the basis for the water management of greenhouse cucumber production and production.
