中国部分烤烟产区模块配方烟叶品质特色分析

为了合理利用不同烤烟产区的模块配方烟叶,采用9个常见烤烟产区同一模块配方烟叶BF-2-1为材料进行研究.结果表明,不同产区烟叶聚类为3个区,分别为:(1)建石、梅州、郴州、毕节、临沂的烟叶为一类,总糖、还原糖含量分别为16.19%～19.92%,12.73%～17.67%;总氮在2.13%～2.38%;烟碱含量在3.1...

Analysis of Quality of the Formula Flue-cured Tobacco from the Different Area in China

The chemical composition of flue-cured tobacco is different due to the different regions and ecological environments.So the formula leaves(BF-2-1) of flue-cured tobacco from nine production areas of China were studied.The results were the following:(1)the leaves from Jianshi,Meizhou,Chenzhou,Bijie and Linyi were clustered as first type,in which the contents of total sugar and reducing sugar were 16.19%-19.92%,12.73%-17.67% respectively;the content of total nitrogen was between 2.13%-2.38% and the content of Nicotine was 3.11%-3.76%;(2) the leaves from Yuxi,Luxi and Sanming were clustered as the second type,in which the contents of total sugar and reducing sugar were 22.05%-23.74%,19.38%-20.26% respectively,the content of total nitrogen was between 2.03%-2.25% and the content of Nicotine was 2.65%-3.10%;(3)the leaves from Simao was the independent type,the contents of total sugar and reducing sugar were 28.55% and 24.05%,the content of total nitrogen and nicotine was 1.66% and 2.07%.It could reduce the work of smoking and subjective errors and accelerate flue-cured tobacco production by using chemical composition of tobacco and clustering analysis
