采用山东靠山生物科技有限公司生产的靠山多霸果菜多功能生物制剂叶面喷雾温室黄瓜,以探讨该制剂对温室黄瓜白粉病的防治效果。试验结果表明,该制剂喷雾后能促进黄瓜植株的生长,黄瓜叶片中的叶绿素含量及净光合速率分别提高4.41%和29.83%,黄瓜白粉病的发病率降低到2.27%,防效显著,并能使黄瓜增产13.16%,667 m2纯收入增加1 733.12元。
Using the backdrop of Shandong Science and Technology Co., Ltd. produced by the backing of more than tyrants Pa in the greenhouse multi-functional biological agents foliar spray greenhouse cucumber to explore the preparation of greenhouse cucumber powdery mildew control effect. The results showed that the spray could promote the growth of cucumber plants. The chlorophyll content and net photosynthetic rate in cucumber leaves increased by 4.41% and 29.83% respectively, the incidence of cucumber powdery mildew decreased to 2.27%, and the control effect was significant The cucumber yield increased by 13.16% and the net income of 667 m2 increased by 1 733.12 yuan.
