日光温室黄瓜生产中一直存在灌水最大,水分浪费严重等现象,针对这一问题,该试验以津育5号黄瓜(Cucumis sativus L)为试材,就交替隔沟灌溉和交替隔沟亏缺灌溉对日光温室黄瓜生长、灌溉水去向、水分利用效率和节水效果等的影响进行了研究.结果表明,交替隔沟灌溉减少了土壤水分的深层渗漏、土壤表面水分蒸发,植株蒸腾速率也略有下降,而植株光合作用没有受到明显影响,使同化产物有利于向果实分配,产量与对照持平,果实商品性和营养品质也有所提高.交替隔沟灌溉可节水37%～48%,作物水分利用效率提高47%～82%.此法简便易行,控漏减蒸效果明显,节水显著,在目前日光温室生产条件下极具推广应用价值.

At present, the irrigation amount during cucumber production in solar greenhouse is excessive, and its water use efficiency is low. Jinyu No.5 cucumber (Cucumis sativus L) was grown under normal irrigation(CK), alternate furrow irrigation (AI) and alternate furrow deficient irrigation(DAD conditions, respectively, to study the effects of these irrigation methods on yield, quality, water-saving and water use efficiency(WUE) of cucumber in solar greenhouse. The results showed that Al and ADI decreased soil deep leakage, soil surface evaporation, transpiration rate (TR), regulated photo-assimilation distribution, improved yield and quality of fruits, and there was no obvious effect on photosynthetic rate. AI and ADI saved water by 37%-48%, increased water use efficiency(WUE) by 47%-82%. The irrigation technology has an important popularization value and a good future.
