摘　　要：为明确营养诱抗剂对常见烟草病害的影响,本试验以“云烟87”为供试品种,研究了几种营养诱抗药剂对田间常见病害的防治效果以及对烟株的农艺性状影响.结果显示,在前期药剂筛选中,叶夫锌和海夫图达能提高烟草抗性相关超氧化物歧化酶(SOD)活性,对烟草花叶病、野火病和赤星病有更好的防治效果,并且对烟草的株高有促生长作用.比较不同施药方式,发现叶面喷施具有更好的病害防效,但对农艺性状没有显著影响.通过在烟草不同生长时期施药比较,发现团棵期施药对烟草病害具有更好的防效,而且对烟草叶宽也具有一定促生长作用.该研究为营养诱抗剂防治烟草病害并提高烟草农艺性状提供了理论基础.In order to clarify the effects of plant inducer agents on common tobacco diseases, using variety “Yunyan 87” as the material, the effects of several kinds of plant inducer agents on the disease resistance and the agronomic traits of tobacco were investigated. The results showed that zinc sulfate and Haf total could improve the activity of resistance-related Superoxide Dismutase(SOD) enzyme in tobacco, and had better control effect on tobacco mosaic disease, wildfire disease and brown spot disease, also increased the height of tobacco plants. By comparing different application methods, it was found that foliar spraying had better effect on control of diseases and no significant effect on agronomic traits. With the application at different growth periods of tobacco, it was found that the application at rosette stage had a better prevention effect on tobacco diseases, and also had a certain growth-promoting effect on tobacco leaf width. This study provides a theoretical basis for tobacco disease control and improvement of tobacco agronomic characters.
