Yield Increase and Disease Prevention Effect of Wenbao Duocai(WBD)in Flue-cured Tobacco
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 tobac-co 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.
