A Preliminary Research Report about the Protective Cultivation on Flue- Cured Tobacco

摘要: 烤烟保护性栽培( 烟田覆盖40 目防蚜网) 试验示范结果表明, 保护性栽培烟田的TMV、CMV、PVY 发病率明显低于对照烟田, 平均产量、产值、上等烟比例、纯收益都高于对照烟田。

Abstract: A protective cultivation test in cured tobacco, which means covering the tobacco field with 40- lattice net guarding against plant louse .It showed that the TMV,CMV,PVY protective cultivation of the tobacco field covering with net was apparently lower than that of the field outside the net. Moreover,the average yield, the output value, the first- class leaf proportion and the profit of the tobacco field with net were higher than that of the field outside the net.
