| 摘 要： | 在1986～2000年连续15年田间系统调查研究的基础上,对花生病毒病的年度流行程度(发病率)与相关因子进行了统计分析。结果表明:花生病毒病的年度流行程度与花生苗期(5～6月份)蚜量的正相关系数、通径系数最大,是花生病毒病流行程度的主导因子,生产上可以花生苗期的蚜量为主要依据,及时提出必要的防治措施,控制花生病毒病的流行程度。

| Abstract: | Through a disease survey in a period of fifteen years(1986 to 2000),epidemic coefficient of peanut virus disease and its correlated factors were analysed and the result showed that there were the large positive correlation coefficient and path coefficient between epidemic coefficient of peanut virus disease and the quantity of aphides in seedling stage(May and June).The quantity of aphides could be used as epidemic coefficient indicator and it could be controlled in agricaltural production after necessary measure were used. |
