| 摘 要： | 在膜下滴灌条件下.灌溉定额为600mm时,研究了不同灌水次数对日光温室黄瓜耗水规律及水分利用效率的变化规律.研究结果表明,灌水次数达18次时,黄瓜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;土壤贮水量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15～18次,既能满...

| Abstract: | Under the drip irrigation,irrigation quota was 600 mm,to study cucumber water consumption and changes of water use efficiency in greenhouse.The results showed that up to 18 times the number of irrigation,the water consumption of the overall strength increased with the growth delay period,the maximum peak in the fruiting stage,then decreased gradually.Along with irrigation increasing,the soil water storage capacity increased,but water consumption of soil significant reduced.Irrigation frequency 15-18 times,t... |
