温室黄瓜节水灌溉指标的研究

Study on water-saving irrigation index for greenhouse cucumber

对日光温室黄瓜滴灌灌水指标进行了研究。结果表明 :秋延后温室黄瓜栽培在灌溉下限为 75 %的条件下 ,最适灌溉上限为 90 % (占田间持水量的百分比 ) ,此时 ,黄瓜产量高、水分利用率高、品质好。从开花结果—拔秧 ,灌溉定额为 1 934.76 m3/ hm2 ,灌水次数 1

The experimental study on water saving irrigation index for greenhouse cucumber shows that on the basis of irrigation start point of 75%,the optimal soil water irrigation maxium is 90% (the percent comparing to the field water capacity).Under 90% soil water,the yield,water effective utilization ratio and the quality are the best.From bloom and fruit bearing to harvest,the whole amount of irrigation is 1 934.76 m 3/hm 2 and irrigation times are ten.
