摘　　要：以生产上的常规种植方式为对照,采用尼龙网(只允许水分通过)隔根形成不同的根土空间,分析不同根土空间对日光温室黄瓜耗水及产量贡献率的影响。结果表明,在结瓜期各处理日最大耗水总量表现一致,均表现为盛瓜期>末瓜期>初瓜期的耗水规律。和对照相比各处理黄瓜产量均高于对照,各处理产量贡献率均达到对照产量的100%以上。处理W20、W30、W40、W10产量分别比对照高出3.49%、2.21%、2.12%、1.95%。因此我们认为黄瓜10cm根土空间就能获得和对照差异不显著的产量。这将为黄瓜节水栽培提供理论依据和技术支撑。Taking the conventionally grown mode as the contrast treatment, through adopting the nylon net to separate the root of cucumber to form root-soil space, this paper studies the effects of different root-soil space on the water consumption and the yield contribution rate of solar greenhouse cucumber. The results show that during the fruit period, the daily maximum total water consumption of each treatment is consistent and the order from big to small is full fruit period, late fruit period and early fruit period. Comparing with the contrast treatment, the yields of different treatments of W20, W30, W40, Wl0 are higher by 3. 49%, 2. 21%, 2. 12%, 1.95%, respectively, and the yield contribution rate of each treatment is more than 100%. So it can be concluded that 10 cm root-soil space of cucumber can get the similar yield of the contrast treatment. The result can provide theoretical basis and technical support for the cucumber water-saving cultivation.
