| 摘 要： | 为了研究烟草青枯病的发生动态预测技术，对‘红花大金元’、‘闽烟35’和‘翠碧1号’烤烟品种的地表上第1叶片中叶柄基部内青枯病病原菌数量及田间病害的发生发展规律进行系统调查，并分析其动态变化及其相互关系。结果表明：不同品种烟株地表上第1叶片中叶柄基部内青枯病病原菌数量与烟草病枯病的发病率有显著的相关性，且烟株叶柄基部含菌量与烟株发病率成正相关，并在一定的温湿度范围内，烟株的发病率随烟株叶柄基部含菌量的增加而增加，并建立了烟株叶柄基部烟草青枯病病菌含量与大田烟株发病率的回归模型。这些模型的建立将对南方烟区，特别是福建烟区烟草青枯病的发生预测及防治决策具有重要实践意义。 |

| Abstract: | The relation of the pathogen quantity of tobacco bacterial wilt in the first leaf at the bottom of a tobacco plant and the outbreak regularity of the disease in different flue-cured tobacco varieties was investigated.The result showed that it was significantly relative between the pathogen quantity of tobacco bacterial wilt and the outbreak regularity of it in different flue-cured tobacco varieties.And the outbreak of the disease in fields was often increased with the development of the pathogen quantity.Therefore,it might be very useful for the forecast and control of tobacco bacterial wilt by the relation of them in south China,especially in Fujian Province. |
