摘要
以惠州冬种马铃薯为研究对象,探索不同气象条件对冬种马铃薯卷叶病毒的影响。以田间调查的形式统计了不同时期冬种马铃薯卷叶病毒的发病情况,并对马铃薯卷叶病毒进行分子鉴定,分析了惠州市冬季气温、相对湿度及降水等气象条件对冬种马铃薯卷叶病毒病的影响。结果表明：3次调查马铃薯卷叶病毒病的平均发病率依次为2.48%、12.6%、70.18%,呈上升趋势;分子鉴定结果显示确为马铃薯卷叶病毒的感染;气象条件对冬种马铃薯卷叶病毒的发生有着重要的影响,其中高温、少雨,相对湿度在70%~80%的气象条件易造成马铃薯卷叶病毒病的发生和传播。
in order to study the effects of different meteorological conditions on the leaf roll virus of winter-planting potato in Huizhou province. In the form of field survey investigated in different periods of winter-planting potato roll leaf virus incidence, and identified potato leaf roll virus molecular, analyzed the Huizhou City winter air temperature, relative humidity, precipitation and other meteorological conditions effects to winter-planting potato leaf virus disease. The results showed that the average incidence rate of potato leaf roll virus disease was 2.48%, 12.6%, 70.18%, and it was increased in 3 times investigation; the results of molecular identification showed that the infection of potato leaf roll virus was indeed; meteorological conditions have important effects on the occurrence of winter-planting potato leaf roll virus, including high temperature and little rain, the relative humidity in 70%~80% are the meteorological conditions that easy to cause the occurrence and propagation of potato leaf roll virus.
