摘　　要：本试验以黄瓜为研究对象,研究了灌溉频率对日光温室黄瓜灌溉水分配和水分利用效率的影响。结果表明:增加灌溉频率有利于减少深层渗漏、土面蒸发,增加土壤储水量。栽培茬口不同,灌溉频率对植株蒸腾、产量和水分利用效率的影响不同,植株蒸腾、产量及水分利用效率冬春茬随灌溉烦率的增加而增加,秋冬茬则相反。The effects of different irrigation rate on distribution of irrigation water and water use efficiency in solar greenhouse were studied. The results showed that water drainage and evaporation decreased but soil water storage increased with increasing irrigation rates. The ef- fects of different irrigation rate on transpiration, yield and water use efficiency were different in different seasons. The transpiration, yield and water use efficiency were increased with increasing irrigation rates in winter-spring period but decreased in autumn-winter period.
