摘要
研究不同农艺措施对打顶后烤烟上部叶片烟碱与总氮含量的动态变化。结果表明,随着烤烟打顶后天数的增加,上部烟叶烟碱量增加而总氮量减少,施氮量与烟碱含量和总氮量呈正相关,而种植密度、留叶数与其呈负相关。
The dynamic changes of nicotine and total nitrogen in flue-cured tobacco with different agronomic treatments were studied. The results indicated that the increasing delay time after topping resulted in the increase of nicotine content and decrease of total nitrogen in upper leaves with which the application level was positively correlated while the planting density and the leaf population were negtively correlated.
