摘要: 为研究丽江特色烟叶的形成机理,以丽江4个植烟区气候、土壤等生态因素和烤烟化学成分的数据资料为基础,分析了各烟区的生态条件及烟叶化学成分。结果表明:(1)丽江各烟区气候差异较大,总体上具有前期光照多、降水少、空气干燥且气温适宜,后期降水多、光照总量偏少但漫射光多、气温偏低且空气湿度大的特点。(2)丽江植烟土壤pH值适宜,有机质含量丰富,具有较强的保肥能力;速效氮、磷、钾含量中等偏高,有效钙和有效钼含量普遍过高;有效镁、有效锌和氯离子含量中等偏高,有效硼含量偏低。(3)丽江各烟区烤烟总糖和还原糖含量均较高,烟碱含量都处于最适范围内,但钾、氯含量普遍低于国外烤烟;两糖比偏低,糖碱比偏高,钾氯比普遍比国外烤烟高。总的来讲,丽江特有的光、温、水匹配方式可能是丽江烟叶风格特色形成的主要生态学外因。

Abstract: To reveal the mechanism of Lijiang tobacco quality,the ecological condition and chemical components of flue-cured tobacco in Lijiang were analyzed based on local data of climate,soil,ecology,and tobacco.The results showed that the climate of tobacco-growing areas in Lijiang was quite different during tobacco growing season.There were long sunshine hours,feasible temperature,low humidity and precipitation during root extending stage,as short sunshine hours but more scattering light,low temperature,high humidity and precipitation during maturing stage.The soil condition had strong capability of storing nutrients and feasible pH value,the content of organic matter was rich,the content of available N,P,K,Mg,Zn and water soluble Cl were medium or high,the content of available Ca and available Mo were quite high,the content of available B was low.The content of total sugar and reducing sugar in tobacco leaves were high,nicotine content was feasible,but K and Cl content were lower than other regions,the ratio of reducing sugar to total sugar was low,the ratio of sugar to nicotine was high,the ratio of K to Cl was obviously higher than other regions.In brief,the combination and distribution of the radiation,temperature and precipitation during the growing season were ecological reason to high quality tobacco in Lijiang.
