Abstract:

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 conventionally 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.
