摘要
通过田间试验,研究了烤烟与草木樨间作对烟草病害的控制效果.结果表明: 烤烟间作草木樨处理对烟草病毒病有明显的控制效果,普通花叶病的发病率和病情指数极显著下降,防治效果为22.58%~80%.间作能不同程度地减轻烟草真菌类病害的危害,防治效果为44.50%~52.91%.在本试验条件下间作对细菌类病害的控制效果不明显.
The field experiment was conducted to study the effects of flue-cured tobacco and sweet clover(Melilotus officinalis lain. ) intercropping on diseases occurrence of tobacco. The results showed that the intercropping practice controlled effectively tobacco virus disease occurrence, especially the incidence and disease index of TMV descended clearly, the control efficiency was up from 22.58% to 80%. And the intercropping practice could reduced tobacco fungal diseases occurrence, the occurrence of fungal diseases decreased by 44.50% -52.91%. But the control effect of intercropping on tobacco bacteria diseases was not evident under the trial condition.
