试验以津育5号黄瓜为试材,研究了基于传统畦灌的不同灌溉方式对灌溉水在黄瓜不同生育期水分分配规律的影响。结果表明:滴灌和渗灌减少了水分深层渗漏量和土面蒸发量,增加了植株蒸腾量,促使更多的水分被植株吸收利用。滴灌和渗灌分别比常规灌溉增产11.6%和15.3%,水分利用效率提高49.9%和68.7%。
To study the effects of different irrigation methods on water distribution of different growth period of cucumber in solar greenhouse,using Jinyu No.5(Cucumis sativus L) as experimental material.Results revealed that leaching and evaporation decreased but transpiration increased under drip irrigation and subsurface irrigation.Drip irrigation and subsurface irrigation increased cucumber yield by 11.6% and 15.3% and increased water use efficiency(WUE) by 49.9%and 68.7%,respectively.
