摘　　要：[目的]为抗逆性肥料在黄瓜上的合理施用提供理论依据和技术指导。[方法]以喷清水为对照,分析喷施不同抗逆性肥料I、II对黄瓜叶片细胞膜透性、MDA含量、可溶糖、可溶性蛋白质和产量的影响。[结果]喷施抗逆性肥料I、II黄瓜叶片电解质渗透率比对照分别低26.0%、12.9%;丙二醛含量比对照低22.0%、39.1%;可溶糖含量分别比对照提高24.6%、27.6%。喷施抗逆性肥料I黄瓜叶片可溶性蛋白质含量略高于对照差;喷施抗逆性肥料II黄瓜叶片可溶性蛋白质含量比对照高15.6%。[结论]抗逆性肥料I、II都可抵御低温给黄瓜带来的影响,可提高黄瓜的产量。[Objective] The theoretic basis and technical guidance of the application of fertilizer containing resisting material was provided.[Method] The effect of the Fertilizer I,Fertilizer II and water as CK,sprayed in cucumber plant,on the cell membrane permeability,the content of malonaldehyde（MDA）,soluble protein,soluble sugar in its leaf and its yield was experimented.[Results] The electrolyte leakage of the plant sprayed with Fertilizer I and Fertilizer II was reduced by 26.0% and 12.9%;the content of MDA was reduced by 22.0%、39.1%;the content of soluble sugar was raised by 24.6% and 27.6%,compared with those of CK,respectively.The content of soluble protein in the plant leaf sprayed with Fertilizer I was higher than that of CK and the content of soluble protein in cucumber leaf sprayed with Fertilizer II was 15.6% higher than that of CK.[Conclusion] The application of Fertilizer I or Fertilizer II could promote the resistance of the cucumber to cold for its yield-increasing.
