| 摘 要： | 通过不同硝态氮比例施用试验。结果表明，施用一定量的硝酸钾能提高烟叶品质。随着硝态氮施用比例的增加。烟碱尤其是上部叶烟碱含量呈下降趋势，烟叶的还原糖和钾含量呈上升趋势。为协调烟叶的糖碱比，龙岩烟区大田生产硝态氮的施用比例以占总施氮量的35％为宜。

| Abstract: | Different nitrate-nitrogen ratio test showed that appropriate KNO 3 amount could improve the quality of flue-cured tobacco leaves.As the nitrate-nitrogen ratio increase,the content of nicotine specially in the upper leaves decrease,while the reducing sugar and potassium content increase.To get the more harmonized sugar /nicotine value,the suitable using ratio of KNO 3 is35percent of the total nitrogen fertilizer in Longyan area. |
