摘要
为明确张家界雪茄烟中部叶适宜的采收时间,本研究以‘古巴七号’为试验材料,针对中部叶设置打顶后10 d(T1)、打顶后15 d(T2)、打顶后20 d(T3)、打顶后25 d(T4)4个采收时间处理,对比分析发酵后烟叶的化学成分、外观质量及感官质量表现,并采用主成分分析方法对29项烟叶品质评估指标进行综合评价。结果表明,主成分分析成功提取5个主成分,累积方差贡献率达到了90.363%,涵盖常规化学、外观质量及感官品质的关键特征。通过构建综合评价函数并计算各处理得分,T4处理的雪茄烟叶综合得分最高,其烟叶化学成分协调性佳、外观品质优且香气物质积累充分。综上,张家界雪茄烟中部叶在打顶后25 d采收可显著提升烟叶品质。
In order to clarify the suitable harvesting time of Zhangjiajie cigar tobacco leaves,four harvesting times were set up,namely 10 days after topping(T1),15 days after topping(T2),20 days after topping(T3)and 25 days after topping(T4),and the chemical composition,appearance quality and sensory quality performance of fermented tobacco leaves were compared and analyzed.The principal component analysis was used to comprehensively evaluate the cigar leaves.The results showed that 5 principal components were successfully extracted from 29 tobacco quality evaluation indexes by using principal component analysis,and the cumulative variance contribution rate of the 5 principal components reached 90.363%.Therefore,the comprehensive evaluation function was established,and the comprehensive score of each treatment was found.It was found that the comprehensive score of cigar tobacco leaves in T4 treatment was the highest.In summary,25 days after topping is the suitable harvest time for the middle leaves of Zhangjiajie cigars,and it is conducive to improving the quality of cigar leaves.
