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。

In this article, we studied the control efficiency of the muhifunctional biological agent Kaoshanduoba, which was produced by Shandong Kaoshan Biological Technology Co., Ltd. for fruits and vegetables, against greenhouse cucumber powdery mildew. The results showed that, spraying the agent promoted the growth of cucumber plants, and the leaf chlorophyll content and net photosynthetic rate of cucumber increased by 4.41% and 29.83% respectively. And after spraying the agent, the cucumber powdery mildew incidence decreased to 2.27%, and the control effect was significant. In addition, the cucumber yield increased by 13.16%, and the net income increased by 1 733.12 Yuan/667 m2.
