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。
Using “Century Emerald” cucumber as test material and CK as CK, the effects of using plastic cloth to separate root and shoot space on water consumption and yield of cucumber in solar greenhouse were studied influences. The results showed that the maximum daily water consumption of different treatments at different growth stages was the same from that of the cucumber alone, both of which showed that there were few early melons, the most melons and the last cucumber ones. Compared with CK, The contribution rates of all treatments were less than 100%, and showed a certain regularity, that is, the higher the contribution rate of soil and rhizosphere was, the higher the contribution rate of yield was, the contribution rate of S40 was 98.06%; the highest of water use efficiency was S20 and higher than that of CK 10.33%, while water consumption less than CK, but the output was only slightly lower than CK, and the yield level difference was not significant.
