| 摘 要： | 以国内主产烟区和津巴布韦共107份烤烟样本为材料，研究了烤烟叶片中磷含量的分布特点，并重点分析了烤烟磷含量与常规化学成分的关系，结果表明：①我国主产烟区烤烟磷含量平均值为(0.43±0.08)%，变幅为0.25%~0.66%；津巴布韦烤烟磷含量为(0.53±0.05)%，变幅为0.45%~0.67%；②不同地区烤烟磷含量的变化为：津巴布韦(0.53%)>东南烟区(0.49%)>长江中上游烟区(0.45%)>西南烟区(0.42%)>黄淮烟区(0.41%)>北方烟区(0.39%)，且差异达到极显著水平；③随着烤烟着生部位的升高，烟叶磷含量有增加的趋势，但不同部位间差异不显著；④烤烟磷含量与烟碱、钾和氯含量达到显著或极显著正相关，与总糖、还原糖含量和氮碱比表现为极显著负相关，与总氮和钾氯比的相关关系不显著；⑤基于烤烟磷含量的聚类结果和不同磷含量水平下化学成分协调性评价结果可知，中、高磷含量类群烟叶的化学成分含量较为适宜，指标间协调性较好，烟叶可利用价值高。

| Abstract: | This paper studied the distribution characteristics of phosphorus contents of 107 flue\|cured tobacco leaf samples from domestic main tobacco areas and Zimbabwe, and analyzed the relationships between phosphorus contents and routine chemical components. The results indicated that: ① the phosphorus content of domestic main tobacco areas ranged from 0.25% to 0.66% with the mean of (0.43±0.08)%, the phosphorus content of Zimbabwe ranged from 0.45% to 0.67% with the mean of (0.53±0.05)%; ② the order of the phosphorus contents in flue\|cured tobacco leaves among different areas was Zimbabwe (0.53%) > Southeast tobacco area (0.49%) > the upper and middle Yangtze River tobacco area (0.45%) > Southwest tobacco area (0.42%) > the Yellow and Huai River tobacco area (0.41%) > North tobacco area (0.39%), and the differences among these areas reached extremely significant level; ③ the phosphorus contents increased with the rise of stalk position, and there was no significant difference among different positions; ④ the phosphorus content in flue\|cured tobacco leaf had significant or extremely significant positive correlation with nicotine, potassium and chlorine contents, and had extremely negative correlation with total sugar, reducing sugar content and nitrogen/nicotine, sugar/nicotine, but had no significant correlation with total nitrogen and potassium/chlorine; ⑤ the clustering results based on the phosphorus contents and harmonic character evaluation of the chemical components at different phosphorus content levels showed that the flue\|cured tobacco leaves with medium and high phosphorus content clusters had proper chemical components, better harmony among indexes and high available value. |
