| 摘 要： | 菌核病是湖南省油菜生产上的主要病害，发生面积大，危害时间长，对油菜生产安全构成严重威胁。对湖南省油菜菌核病的发生流行规律及影响因素进行分析和总结，提出了以农业防治为主，其它防治为辅的综合防治策略，并认为3月份的月平均气温与油菜菌核病的发生面积比率有显著的正相关关系，可用来对当年油菜菌核病的发生流行程度进行概念性预测。

| Abstract: | Sclerotium blight is one of the most dangerous diseases to rapeseed ,and its damage took on characteristics of vast area and long time so it was regarded as the main intimidation to rapeseed production in Hunan province. The occurrence regulation and influencing factor of Sclerotium blight of rapeseed in Hunan province were analyzed and summarized ,and the integrated control strategy which gave priority to agricultural control was brought forward. At the same time, significant positive correlation between the mean temperature in March and the occurrence area ratio of Sclerotium blight of rapeseed was observed. This result could be used to forecast the occurrence degree of this disease. |
