| 摘 要： | 试验结果表明，陕西烟田蚜传病毒病的介体和初侵染毒源均来自当地冬油菜田；蚜传病毒病的主要种类有CMV、TEV和PVY；有翅桃蚜迁入烟田有2个高峰期，第1高峰期出现在5月中旬，第2高峰期出现在6月中旬；各品种之间存在着不同的耐病性，其中MsB07、MsG02耐病；以陕西泾阳1994－1998年5年的烟草病情资料、当地气象资料和相关资料建立了烟田蚜传病毒病发病率（Y）预测预报模型：Y＝－6．909＋0．011528X4＋0．0026X5＋0．001785X12＋0．448X13。

| Abstract: | The winter rape was the most important primary virus and aphid vector source for tobacco in Shaanxi Province. The main species of tobacco aphid-transmitted virus were cucumber mosaic virus (CMV), tobacco etch virus (TEV) and potato virus Y (PVY) . There were two aphids migration peak to tobacco field, respectively in mid-May and June. The tobacco varieties MsB07 and Ms G02 have good tolerance to virus diseases. A forecasting model was established as the occurrence of the virus disease Y = -6.909 0.011528X4 0.0026X5 0.001785X12 0.448X13, using five-year data from Jingyang experimental station. |
