| 摘 要： | 研究了马尾松赤落叶病在湖北省的分布及危害、症状和病原,着重研究了该病的流行规律.结果表明,松赤落叶病流行的主要诱因是气象因素,它决定于前一年的冬季气温和当年降雨量,其发生流行与头年冬季气温呈正相关,与当年降雨量呈负相关.在目前连续暖冬的条件下,降雨量是最关键的因素. |

| Abstract: | The distribution pattern,damage degree,symptoms of pathogen Hypoderma desmazierii Duby were studied.The research focused on the epidemic trend of the disease on masson pine. It showed that the temperature in winter and annual rainfall were the main inducements of the disease.A trend was found that the higher temperature during winter and less annual rainfall,the easier of the disease to develop in the following year. In current situation of continuing warm winter,rainfall would be the most critical factor to affect the development of the disease. |
| Keywords: | Hypoderma desmazierii Epidemic trend Annual development regularity |
