| 摘 要： | 对比试验结果表明:烤烟施用烟钾、晟绿丰2号和赤霉素,上部叶面积比对照分别增加21.73%、22.79%、25.65%;烟钾对提高中上等烟比例效果明显;晟绿丰2号有助于提高单位面积产值;脱落酸可导致叶片变薄,中上等烟比例下降。烟钾和晟绿丰2号对降低烟碱含量、增加钾含量有一定的效果,烟碱比比对照分别降低24.13%、31.64%。赤霉素和脱落酸在降低烟碱方面有一定的效果。以晟绿丰2号和赤霉素促进上部烟叶开片和降碱的综合效果较好。

| 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. |
