贵州省威宁县烟草花叶病发生情况调查初报

为摸清烟草花叶病在威宁烟区的发生情况，以更准确地进行预防，于2012年选择不同烟草品种、海拔及轮作情况的烟草种植区对烟草花叶病的发生情况进行调查。结果表明：不同烟草品种间发病情况不同，贵烟2号抗病性最弱，韭菜坪2号次之，抗病性最强的是2010-6；不同海拔高度田块病害发生情况不同，病害严重程度表现为山脚〉山腰〉山顶；不同轮作地块病害发生存在极显著差异，隔年轮作地烟草花叶病发病最轻，连作地发病较重，且连作年限越长，发病越重。...

In order to clarify the occurrence of Tobacco mosaic virus in Weining for better prevention and control, the investigation was made about this disease in the field with different varieties, altitudes and rotation situations in 2012. The resuJts indicated that the disease occurrence differed with the varieties. Guiyan No.2 had the weakest disease resistance, followed by Jiucaiping No.2, and 2010-6 was the strongest. At different altitudes, the disease severity showed as foot 〉 hillside 〉 hilltop. The disease incidence of different rotation situations of tobacco field had very significant difference, and the disease incidence was the least serious in the rotation field, but it was serious in the
