| 摘要: |
| 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。从开花结果一拔秧，灌溉定额为1934.76 m3/hm2，灌水次数10次效果较好。 |

| Abstract: |
| 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 m3/hm2 and irrigation times are ten. |
| Key words: greenhouse cucumber irrigation saving-water index |
