Field experiment was conducted to study the effects of application of amino-oligosaccharins and potassium nutrition regulator on tobacco mosaic virus disease and yield and quality of tobacco leaves.The results showed that:the application of amino-oligosaccharins and potassium fertilizer reduced tobacco mosaic virus disease incidence and disease index effectively,and the average control effect reached 56.31％.The economic characters such as yield,output value,average price and the ratio of superior leaf of tobacco leaf were significantly increased by 27.60％,44.26％,13.02％ and 42.48％,respectively,and the appearance quality and smoking quality of tobacco leaves were improved.%为探索防治烟草普通花叶病的农艺措施,采用田间试验,研究了氨基寡糖素和钾营养调节剂配施防治烟草普通花叶病毒病的效果及对烟叶产量、质量的影响.结果表明,氨基寡糖素和钾营养调节剂配合施用能有效降低烟株普通花叶病毒病的发病率和病情指数,平均防效达到56.31％,两者配施还明显提高了烟叶的产量、产值、均价、上等烟比例等经济指标,分别较对照(喷施清水)提高27.60％、44.26％、13.02％、42.48％,并能提高烟叶的外观质量和评吸质量.
