摘　　要：以烤烟203为材料,开展“稳保多彩”增产剂对烟草的增产提质防病效果试验。结果表明,“稳保多彩”处理(处理A、处理B)与CK比较,处理A产量增加3.04%,产值增加6.35%,上等烟比例提高2.35%,均价提高0.77元/kg;处理B产量增加1.52%,产值增加3.73%,上等烟比例提高2.35%,均价提高0.77元/kg。“稳保多彩”处理使烟草花叶病的发病率和病情指数明显降低,也使赤星病的病情指数明显降低,对两种病害均有一定防效。Using flue-cured tobacco 203 as material,an experiment was conducted to investigate effect of Wenbao Duocai(WBD)yield-increasing agent on tobacco yield increase,quality improvement,and disease prevention.The results showed that compared to CK,Treatment A increased the yield by 3.04%,the output value by 6.35%,the proportion of high-grade tobacco by 2.35%,and the average price increased by 0.77 yuan/kg.Treatment B increased output by 1.52%,the output value by 3.73%,the proportion of high-grade tobacco by 2.35%,and the average price increased by 0.77 yuan/kg.The incidence and disease index of tobacco mosaic disease were significantly reduced,as well as the disease index of red star disease,and it had a certain control effect on both diseases.
