摘要
为探明延边地区烟草病毒病的发病规律,为生产优质高产烟叶提供科学有效的病毒病预防措施,简要分析了延边地区2010和2011年病毒病与气象因子的关系。结果表明,延边地区进入6月份,当日平均温度高于16.0℃,烟草病毒病就可以发生。病毒病发病前10d的日平均温度高,日照时数大于6h的天数多,降雨量少的情况下,病毒病发生严重。
In order to reveal about the pathogenesis regularity of tobacco virus disease and provide scientific and efficient precautions of virus disease for producing high quality and high yield tobacco,the relationship between the virus disease and meteorological factors in 2010 and 2011 in Yanbian area was investigated.
