烟草霜霉病是一种毁灭性的烟草病害,目前在中国尚无分布。本研究依据烟草霜霉病在世界范围内的已知分布数据,采用GARP生态位模型预测分析了烟草霜霉病在中国的潜在适生区。结果显示烟草霜霉病在中国适生风险较大的地区分布在西南、华中、华东,覆盖大部分烟草种植区。该病害一旦侵入并流行将给我国烟草种植业带来严重损失,应及时采取防控措施。
Tobacco downy mildew is a devastating tobacco disease that is not currently distributed in China. Based on the known worldwide distribution data of downy mildew in tobacco in our country, the potential niche area of tobacco downy mildew in China was predicted and predicted by GARP niche model. The results showed that tobacco downy mildew was distributed in most of the tobacco growing areas in southwestern China, central China and eastern China in areas with greater risks to China’s health. Once the disease invaded and became popular, it would bring serious losses to the tobacco industry in our country. Therefore, we should take timely prevention and control measures.
