| 摘 要： | １９９０－１９９４年研究结果表明，低温是诱发气候斑病的主要因素，不同品种抗性差异显著，氮钾比失调，偏施碳铵地发病严重，当大面积种植感病品种，寄主处于感病阶段，遇气温突然下降和多雨时，最易流行。在防治上，采取以农业防治为主、化学辅的有效措施。

| Abstract: | The systematic observations and experiments during 5 years (1990 - 1994)re-vealed that low temperature was the main causal agent of weather fleck of tobacco. More serious weather fleck occured in tobacco fields when the ratio of nitrogen to potassium was out of balance or the ammonium bicar-bonate was excessively used. Differences of resistance to weather fleck among various varieties were remarkable,and this disease became epidemic when susceptible varieties were planted in large areas. Effective control measures were studied and recommended for practices. |
