通过试验分析,说明膜下沟滴灌、膜下滴灌、膜下渗灌、膜下沟灌等4种灌溉模式对日光温室黄瓜的单株耗水量、耗水系数、单瓜耗水量、用水效率有显著性差异的影响,而对黄瓜的单株产量、节间长、叶的宽度、叶的长度的影响没有显著性差异。在黄瓜单株产量、节间长、叶的宽度、叶的长度没有显著性差异的情况下,以膜下渗灌模式最为节水,即单株产量最高,为7.452 kg/株,单株耗水量最少为58.345 kg/株,耗水系数最低为7.681 dm3/kg,用水效率最高为130.2 g/dm3,单瓜耗水量最低为1.25 dm3/单瓜。黄瓜的单株月产量在1年的不同月份之间有着极显著性差异,其中以7月份单株月产量最高为1.6～1.8 kg/株。
Through experimental analysis, the effects of four irrigation modes, including drip irrigation under mulch, drip irrigation under mulch, infiltration under mulch and furrow irrigation under mulch, on water consumption, water consumption coefficient, water consumption per plant and water use efficiency of cucumber in solar greenhouse Sexual differences, cucumber yield per plant, internode length, leaf width, leaf length no significant difference. Under cucumber yield per plant, internode length, leaf width and leaf length were not significantly different, the most water-saving irrigation pattern under the membrane, namely the highest yield per plant was 7.452 kg / plant, plant consumption The minimum water volume is 58.345 kg / plant, the lowest water consumption coefficient is 7.681 dm3 / kg, the highest water use efficiency is 130.2 g / dm3, and the lowest single water consumption is 1.25 dm3 / single melon. The monthly yield per plant of cucumber had extremely significant difference between different months of one year, among which the highest monthly yield per plant in July was 1.6 ~ 1.8 kg / plant.
