Abstract
The effect of B, Mg, Zn, Mn on the production and quality of flue_cured tobacco were studied, the result were as follows: Mn, Zn and Mg fertilier could increase the productive value permu from 8% to 11% B fertilizer decrease the production and quality, Mn and Zn fertilizer could preomote the activity of nitrate reductase and photosynthesis. The content of chlorophyll was higher in this treatment. But B fertilizer decrease these indices: The indices under treatment of Mg fertilizer were near that of control. The treatment under Mn fertiliter could increase the content of total nitrogen, protein, total sugar, reductive sugar and nicotine and decrease sharply the content of Cl.All indices were slightly increased by the treatment of Zn fertiliter. Mg fertiliter increase the contents of Cl, but leading to strong imbalance of acid and alkli in this treatment. B fertiliter increased the contents of nicotine and reductive sugar, but decreased the content of Cl. So applying Mn and Zn fertilizer properly had promoting effects on the physiological and biochemcal indices and the prodution and quality of flue_cured tobacco.
