| 摘 要： | 立足巫溪烟区2011年烟草普通花叶病发生流行的概况和新特点,采用系统调查、试验研究和资料整理相结合的方法,阐述了花叶病发生的客观原因,重点分析了巫溪县2011年度气象条件、花叶病暴发流行的规律和花叶病药剂防治效果。结果表明,气候条件是影响花叶病的主要因素。由于受年度4-6月份气候条件的影响,2011年花叶病暴发共出现3次高峰,每次发病高峰都与盛发前半个月左右的大范围降雨、低温高湿寡日照以及雨后气温骤升有关。药剂防效试验结果表明,施用药剂对预防烟草花叶病具有明显的效果,但在烟株感染病源后,施药对花叶病并不能起到有效的防治作用。

| Abstract: | Based on the occurrence situation and the new characteristics of tobacco mosaic virus(TMV) in Wuxi of the year 2011,the article expounded the objective reasons of the disease through systemic investigation,field experiment and date sorting.The study especially analyzed the meteorological conditions in 2011,the disease prevalence regularity and the control effects of chemicals on TMV.The research on the occurrence regularity of TMV showed that climatic conditions were the main factors affecting the disease.There were three TMV peaks in 2011,as a result of the meteorological conditions in April to June.The peaks were concerned with a wide range of rainfall about half a month before,low temperature,high humidity and scant sunshine,and the temperature jump after the rain.The control experiment results showed that the chemicals could obviously prevent the mosaicdisease,but once tobacco plants were infected,the effect using chemicals was limited. |
