摘　　要：以"世纪绿宝"黄瓜为试材,以生产上的常规种植方式为对照(CK),研究了采用塑料布隔根形成不同的根土空间对日光温室黄瓜耗水和产量贡献率的影响。结果表明:单从黄瓜结瓜期来看各处理不同生育时期日最大耗水规律表现一致,均表现为初瓜期少,盛瓜期最多,末瓜期又表现出下降;与CK相比,各处理产量贡献率均小于100%,并且表现出一定的规律性,即根土空间越大产量贡献率越高,S40产量贡献率达到98.06%;水分利用效率以S20为最高,比CK高出10.33%,同时耗水量比CK少,但产量只略低于CK,且产量水平差异不显著。Taking ＇Shiji Lvbao＇ cucumber as material,by separating plastic cloth interlayer on root,the effect of different root-soil space on water consumption and yield contribution rate were studied with the production of conventiormlly grown as CK. The results showed that from the fruiting period,each treatment at different growth stages, the regularity of maximum daily water consumption were consistent, the regularity was less water consumption in the early fruit stage, the most exuberant water consumption in the full fruit stage,and showed a decline in the late fruit stage. Compared with the CK,the contribution rate of yield was less than 100% ,and it showed some regularity that the more soil-root growing space the higher contribution rate to yield,the yield contribute rate of S40 up to 98. 06%. The highest water use efficiency was S20 and higher 10. 33% than CK,at the same time water consumption less than CK, but production only slightly lower than CK and no significant difference in yield.
