Abstract

The comparative test showed that applying Yanjia,Shenglufeng No.2 and gibberellin could increase the upper leaf area of flue-cured tobacco by 21.73%,22.79% and 25.65% respectively;Yanjia had obvious effect on enhancing the ratio of mid~high grade tobacco leaves;Shenglufeng No.2 was helpful to increasing the production value per unit area;abscisic acid made leaves thin and the ratio of mid~high grade leaves drop.Yanjia and Shenglufeng No.2 had certain effect on reducing the nicotine content and increasing the potassium content,and after applying them,the nicotine content reduced by 24.13% and 31.64% respectively as compared with CK.Gibberellin and abscisic acid only reduced nicotine content.Shenglufeng No.2 and gibberellin had better comprehensive effects on the developing leaf area and reduction of nicotine content in upper leaves of flue-cured tobacco.
