摘　　要：不同硅源制剂对葡萄白粉病防治效果的研究结果表明,硅酸钠、正硅酸乙酯和纳米硅对葡萄白粉病均有明显的抑制作用,硅酸钠、纳米硅、正硅酸乙酯对室内盆栽葡萄苗白粉病防效在处理15 d后分别为42.65%、24.80%、21.17%,对葡萄离体叶圆片白粉病的防效在处理9 d后分别为47.06%、40.14%、35.53%,以硅酸钠处理的效果最好。The effect of application different silicon compounds on grape powdery mildew was studied. The result showed the grape powdery mildew was significantly inhibited by application three silicon compounds. The control efficacy on powdery mildew of indoor potted grape treated by nanometric silicate, sodium silicon and TEOS after 15 d was up to 42.65%,24.80% and 21.17% respectively. For isolated grape leaves, it was up to 47.06% ,40. 14% and 35.53% respectively after 9 d. It indicated application sodium silicate was the best treatment to control grape powdery mildew.
