电解水对黄瓜白粉病的防效以及对黄瓜生长和品质的影响

Effect of electrolyzed water on controlling cucumber powdery mildew and cucumber growth and quality

利用电解水喷施大棚黄瓜,研究其对黄瓜白粉病的防治效果,以及对植株生长指标、果实品质及产量的影响。结果表明,施用农药、先喷酸性电解水后喷碱性电解水、酸性电解水、及先喷碱性电解水后喷酸性电解水4个处理后黄瓜叶面病情指数显著降低,最终防治效果分别为88.5%、75.1%、72.8%、57.6%,碱性电解水处理防效为15.5%。电解水除对黄瓜植株具有一定的促徒长作用外,对黄瓜果实品质和产量未见不利影响,且酸性电解水和先喷酸性电解水后喷碱性电解水可增加植株根部、地上部分干重,促进黄瓜叶面生长。

Effect of electrolyzed water on controlling cucumber powdery mildew and cucumber growth,quality and production quantity were studied.The results showed that disease index of cucumber powdery mildew on cucumber leaf decreased significantly by four treatments as spraying acidic eleclrolyzed water（AEW）,spraying AEW basic electrolyzed water（BEW）,spraying pesticides,spraying BEW followed by AEW with control efficiency of 72.8%,75.1%,88.5%,57.6%,respectively,and control efficiency of treatment by spraying BEW was 15.5%.There was no obvious negative impact on yield and fruit quality of cucumber by treatment with electrolyzed water except some spindling growth,while spraying AEW and spraying AEW followed by BEW could increase plant dry weight and conduced to leaf growth.
