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。
Based on the systematic investigation of 15 consecutive years from 1986 to 2000, the annual prevalence (incidence rate) and related factors of peanut virus disease were statistically analyzed. The results showed that the positive correlation coefficient between annual prevalence of peanut virus disease and the amount of aphids in peanut seedlings (May-June) was the largest and the path coefficient was the largest. It was the dominant factor in the epidemic degree of peanut virus. As the main basis for the timely introduction of the necessary prevention and control measures to control the prevalence of peanut virus disease.
