中文摘要:
      在宁夏干旱区日光温室膜下滴灌条件下,研究了不同灌水量对日光温室黄瓜耗水规律和土壤水分利用效率的影响,试验结果表明: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,在各个生育期各处理日耗水强度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。灌水量达到563 mm时,完全能满足黄瓜水分需求,产量最高,且水分利用率达到33.4 kg/m3。
英文摘要:
      A study was carried out on the effects of different irrigation amount on irrigation water consumption and soil water use eficiency of greenhouse cucumber with drip irrigation under film mulching in arid areas of Ningxia. The re-sults showed that: the water consumption increased with cucumber plant qrowth， the maximum time was at the fruit stage, and then it declined gradually. Under different treatments in each stage， the water consumption of cucumber in-creased after irrigation amount increased, while the soil water consumption reduced after irrigation amount increased. When the imigation amount was up to 563 mm，the irigation water could satisfy the needs of cucumber and had highest yield, and water use fficiency was 33.4 kg/m3.
