| 摘 要： | 通过在湖南主产烟区5点16年次以上系统调查，发现赤星病季节流行呈逻辑斯蒂曲线增长，发病程度年间波动大，分析了发病轻重与环境因子的关系，提出用发生型法及积温法预测赤星病发生期，用孢子捕捉法及多元相关法预测发生程度。

| Abstract: | It was found out that the prevalence of tobacco brown spot disease Alternaria alternata (Fr.) Keissler presented growth with Logistic curve pattern,and the degree of disease fluctuated greatly among different years in the tobacco region of Hunan.The relationship between the degree of disease and circumstance factors was analysed,only to forecast the occurring time by the occurring pattern and accumulated temperature principle,and to forecast the degree of disease occurring by catching spores method and multianalysis method. |
