贵州不同生态烟区烤烟质量状况分析

Analysis on Quality of Flue-cured Tobacco Planted in Different Ecological Areas of Guizhou Province

为探索烟叶特色的地域性差异，为建立不同生态烟区特色烟叶品质特征评价体系提供依据，对贵州5大生态烟区烟叶质量状况进行了比较分析。结果表明：在相同的栽培管理条件下，烟叶产量在130～155kg／667m^2，产值均在2000元／667m^2左右，烟叶单叶重表现为黔西北最高，黔北、黔东最小；含梗率黔北最高，黔西南、黔东最低；单位叶面积重黔西北最大，黔北、黔东最小；黔西南、黔西北及黔中烟碱含量在2．2％左右，黔东最低（1.73％）；总糖含量黔西南、黔西北两地相对较高，在30％以上，黔中最低（28．83％）；钾含量黔北、黔中及黔东相对较高；各地烟叶评吸质量均较好，可作为卷烟工业的优质原料。

The quality of flue-cured tobacco planted in five main ecological tobacco areas in Guizhou was analyzed and compared to provide the basis for setting up different evaluation systems of tobacco quality characteristic under different ecological conditions. The results showed that the tobacco yield was 130-155 kg/667m^2 , the average output value was about 2 000 Yuan/667m^2, the weight of single tobacco leaf from Qianxibei area was the highest and that from Qiandong area was the lowest, the stem rate from Qianbei area was the highest and that from Qiandong area was the lowest, the weight of unit leaf area from Qianxibei area was the highest and that from Qiandong was the lowest, the nicotine content of tobacco leaves from Qianxinan, Qianxibei and Qianzhong areas was about 2.2% and that from Qiandong area was 1.73%, the total sugar content of tobacco leaves from Qianxinan and Qianxibei areas was above 30% and that from Qianzhong area was 28.83 %, the potassium content of tobacco leaves from Qianbei, Qianzhong and Qiandong areas was relatively higher, and the smoking quality from five tobacco areas was good for the quality raw material in cigarette production.
