| 摘 要： | 为了正确评价感染烟草花叶病并为表现症状烟株的产质量损失研究提供参考依据．在当前优质烟生产管理条件下，通过研究6个不同基因型烤烟新品系在大田期受烟草花叶病危害至9级的病株与未感病的正常烟株进行对比研究．结果表明：1）烟草花叶病对上等烟比例的损失达85．5％，对产值和产指的损失分别达27．2％和24．2％，对产量、均价和级指的损失分别达14．3％、15．2％和13．2％，而对上中等烟比例的损失仪达10．4％；2）烟叶生产中，感染烟草花叶病的烟株可以通过加强田间管理、增加通风透光和改善营养状况等措施，达到提高中等烟比例来最大限度地降低产质量的损失．

| Abstract: | To provide reference for evaluating correctly main economic characters damage of Tobacco mosaic virus during the tobacco growing, six different new Flue-cured tobacco varieties were studied through comparing differences of main economic characters between healthy plants and unhealthy plants because of tobacco mosaic virus infection, under the current high quality tobacco leaves production measures. The results showed that ： 1 ） Losses of superior grade tobacco leaves proportion reached 85.5 % of output value, and yield index amounted to 27.2% and 24.2% respectively of the yield, average price and grade index was 14. 3% , 15.2% and 13.2% respectively , and the superior and middle grade tobacco leaves proportion reached 10. 4% ;2） It could be realized to increase middle grade tobacco leaves proportion and economic income through strengthening field management measures, increasing ventilation and sunlight, and improving tobacco plant nutrition in the course of tobacco leaves production. |
