摘　　要：为了探索导致昆明烟叶氮碱比失调的原因,弥补制约昆明烟叶质量提升的这一关键短板.采用以“烟站”为中心的均衡取样法对昆明烟叶氮碱比协调性现状进行评价,使用烟样“均一性”法则对2008—2013年各部位烟叶氮碱比协调性的变化规律进行分析.结果表明,烟叶总氮、烟碱及氮碱比部位之间差异有统计学意义,总氮和烟碱单项指标均在合理范围内.但氮碱比普遍表现为下部叶不协调,上部叶协调性较好,中部叶局部区域不协调.同时,针对可能导致烟叶氮碱比失调的原因及其调控技术措施查阅了相关文献资料,并提出了改善烟叶氮碱比协调性的调控技术措施,对正确评价昆明烟叶氮碱比现状和改善昆明部分烟区烟叶氮碱比失调问题具有重要的参考价值.In order to find out the cause of the imbalance of nitrogen to nicotine ratio in Kunming tobacco leaves, make up the key short board that affects the quality of tobacco leaves in Kunming area, the nitrogen to nicotine ratio coordination of tobacco leaves in Kunming was evaluated by using the balanced sampling method centered on “tobacco station”, and the regularity of nitrogen to nicotine ratio coordination of tobacco leaves in different parts from 2008 to 2013 was analyzed by the Law of Sample Uniformity. The results showed that the differences of total nitrogen, nitrogen to nicotine ratio of tobacco leaves at different parts were of statistical significance. The single indexes of total nitrogen and nicotine were within a reasonable range. However, the nitrogen to nicotine ratio generally showed incongruity in the lower leaves, good coordination in the upper leaves and partial incongruity in the middle leaves. Meanwhile, in view of the possible causes of nitrogen to nicotine ratio imbalance and the technical measures for its regulation and control, the relevant literatures were consulted, and the regulation and control measures for improving the coordination of nitrogen to nicotine ratio were put forward, which has important reference value for correctly evaluating the present situation of nitrogen to nicotine ratio of tobacco leaves and improving the problem of nitrogen to nicotine ratio imbalance of tobacco leaves in part of Kunming tobacco growing areas.
