摘要
再生水的灌溉利用是国内外有效缓解农业用水紧张的重要举措之一。采用大田试验方法,以地下水滴灌为对照,分析研究了不同比例再生水滴灌对黄瓜生长及产量的影响。结果表明,和正常施肥的对照处理相比,在不施肥的情况下,全部采用再生水滴灌处理对黄瓜的生长发育和产量形成均表现出一定的促进作用,而其他也不进行施肥的较小比例的再生水滴灌处理中,黄瓜生长指标和产量表现出和对照相当或者略低的水平。因此,只要配以适当的农艺措施和灌溉制度,可以采取全部再生水滴灌,或者采用一定比例再生水灌溉和适当施肥相结合的方式,进行黄瓜的种植。
Reclaimed water drip irrigation is one of the effective measures to effectively alleviate the scarcity of agricultural water resources. The influences of reclaimed water drip irrigation on the growth and yield of cu cumber were studied by using field experimental method and taking drip irrigation with groundwater as con trast treatment. Results indicate that compared with the contrast treatment of drip irrigation with groundwa ter under normal fertilization, the growth and yield of cucumber were improved in the treatment of drip irri gation with 100 % reclaimed water under no fertilization. Given no fertilization either, the growths and yields of cucumber in the other treatments of drip irrigation with a certain proportion of reclaimed water were equal to or slightly lower than the contrast treatment. Therefore, in the condition of appropriate agronomic meas ures and irrigation schedule, drip irrigation with 100% reclaimed water, or a certain proportion of reclaimed water companied with appropriate fertilization, could be used for the cucumber cultivation.
