摘要
为了解来凤县雪茄烟核心区烟叶矿质元素含量与感官质量的关系,在来凤县漫水乡、绿水乡、旧司镇采集了雪茄烟叶样品,并进行烟叶氮、磷、钾、钙、镁、硫、硼、锌、铁和感官质量的测定与分析。结果表明,来凤县雪茄烟叶氮、硫、钾、锌和氯含量以绿水乡烟区较高,磷和铁含量以漫水乡烟区较高,钙和镁含量以旧司镇和漫水乡烟区较高。感官质量以漫水乡烟区雪茄烟叶最好,其次为旧司镇烟区。雪茄烟叶感官质量与烟叶氮、钾、氯、硫、锌含量呈显著负相关,相关系数分别为-0.708、-0.753、-0.627、-0.616、-0.757;与烟叶钙含量呈显著正相关,相关系数为0.663。逐步回归分析表明,影响雪茄烟叶感官质量的主要矿质元素为氮和钾含量(均为负相关),回归方程为Y=107.08-6.22X_(1)-2.24X_(2)(R=0.854)。
In order to understand the relationship between mineral elements content and sensory quality of cigar tobacco leaves,the samples were collected in Manshui Town,Lvshui Town and Jiusi Town of Laifeng County for the measurement of nitrogen,phospho⁃rus,potassium,calcium,magnesium,sulfur,boron,zinc,iron and sensory quality.The results showed that the contents of nitrogen,sulfur,potassium,zinc and chlorine in cigar tobacco leaves were higher in Lvshui Town,phosphorus and iron contents were higher in Manshui Town,and calcium and magnesium contents were higher in Jiusi Town and Manshui Town.The sensory quality of cigar tobac⁃co leaves was best in Manshui Town,followed by Jiusi Town,while it was significantly negatively correlated with nitrogen,potassium,chlorine,sulfur and zinc contents,and the correlation coefficients were-0.708,-0.753,-0.627,-0.616,-0.757,respectively.There was a positive correlation between tobacco calcium content and sensory quality,and the correlation coefficient was 0.663.Step⁃wise regression analysis indicated that the nitrogen and potassium contents were the main mineral elements affecting the sensory quali⁃ty of cigar leaves(both negative correlation),and the regression equation was Y=107.08-6.22X1-2.24X2(R=0.854).
