| 摘 要： | 为了探讨气候资源配置差异，解决生产后期不利因素制约烟叶成熟、影响烟叶品质的问题，通过适度提前移栽并对不同移栽期烤后烟叶化学成分、香味成分、外观及评吸等54项指标间相关性及主成分分析，发现甜度、糠醛、糠醇、巨豆三烯酮1、巨豆三烯酮4和叶片生长期有效积温均值等6个指标与其余指标间表现出高度的相关性。3月10日移栽烟叶的上部叶色度最好，总氮较高且总糖最低，同时中部叶的甜度最高且苯乙醇含量最低，能较好地符合皖南优质烟质量评价指标体系，生产上可以探索适度提前移栽获得较好中部叶和上部叶的配套栽培措施。

| Abstract: | In order to investigate the difference of climate resources and resolve the problems which adverse factors inhibit leaf maturity and affect leaf quality, we analyzed 54 factors of flue-cured tobacco including chemical components, flavor components, appearance quality and sensory evaluation etc. through moderately early transplanting. The results showed that a high correlation existed between the indexes of sweetness, furfural, furfuryl alcohol, megastigmatrienone 1, megastigmatrienone 4 and effective accumulated temperature at leaf growth?stages and the rest indexes. Compared with transplantation in normal period, the tobacco plants transplanted on 10th March had the best color of upper leaves, relatively high TN content, and the lowest total sugar content. Meanwhile, the sugariness of central leaves was highest, and the phenethyl alcohol content was lowest. The results can well match with the tobacco quality evaluation index system for high-quality flue-cured tobacco in Anhui Province, and provide suggestion to explore the proper cultivation measures to obtain the better central and upper leaves |
