利用气相色谱质谱联用技术测定了“云烟”品牌卷烟烟丝中呋喃酮、异戊酸异戊酯、麦芽酚、薄荷醇、乙基麦芽酚和茴香脑等6种烟用加香特征化合物，利用主成分分析法对加香特征化合物的检测数据进行分析处理，按累积贡献率大于80％提取2个主成分，求得加香特征化合物的2个主成分得分及综合得分，测算出加香均匀性系数。将其应用于昆明卷烟厂制丝生产中2个批次样品的加香均匀性评价，并与单特征化合物加香均匀性评价相比较，结果表明，提出的方法是可行的，为加香均匀性评价探索了一种新的途径。

Pot experiments and field experiments with orthogonal regression design were performed to investigate interactive effects of N, P and K fertilizers on total sugar in flue-cured tobacco leaves. Single-factor analysis showed that total sugar content of tobacco leaves increased and then decreased steadily with increase of fertilization of phosphorus and potassium, and decreased steadily with increase of nitrogen fertilization in limited range of fertilization. Interaction analysis indicated that there existed a threshold value in interaction of nitrogen and phosphorus. When fertilization was lower than the threshold value, interaction between them was synergistic, otherwise it was antagonistic. The optimal amount in pot experiment from the optimized model was 7.5 g·pot-1 to10 g·pot-1 for N, 10 g·pot-1 to 20 g·pot-1 for P2O5, and 12.5 g·pot-1 to 25 g·pot-1 for K2O. The optimal amount in the field experiment from the optimized model was 52.5 kg·hm-2 to 78.75 kg·hm-2 for N, 105 kg·hm-2 to 157.5 kg·hm-2 for P2O5, and 131.25 kg·hm-2 to 262.5 kg·hm-2 for K2O, respectively.
