摘要: 以曲靖市9个主要植烟区烟叶为研究对象,探究曲靖市烟叶感官质量空间分布特征。于2022年10月在曲靖9个植烟区采集227个初烤中部烟叶,测定烟叶感官质量、外观质量、物理特性、化学成分,采用ArcGIS分析曲靖烟叶感官质量空间分布,通过随机森林等方法探究外观质量、物理特性和化学成分对感官质量的影响。结果表明,曲靖烟区烟叶总体感官质量较好,但具有空间差异性,从北向南呈抛物线型变化,东西走向呈倒“U”形,都表现为两边低中间高。相关性分析发现,颜色、色度、总糖、还原糖、氧化钾与感官质量具有显著正相关关系;单叶重、填充值、总氮与感官质量呈显著负相关关系。采用随机森林模型分析各指标对烟叶感官质量的贡献度,发现对感官质量影响程度由强到弱为总糖、还原糖、总氮、钾、色度。综上所述,曲靖市9个植烟区烟叶感官质量存在空间差异性,可为工业企业特色化原料选择提供参考。造成差异的原因可能与烟叶总糖、还原糖、总氮、钾含量变化有关,因此,建议在烤烟种植过程中通过定向技术研究调控烟叶中总糖、还原糖、总氮及钾含量来优化或稳定曲靖市烟叶感官质量。

Abstract: Based on tobacco leaves in nine major tobacco-planting regions in Qujing City, the spatial distribution characteristics of sensory quality of tobacco leaves in Qujing City were explored. In October 2022, 227 primary roasted middle tobacco leaves were collected from nine tobacco-planting regions in Qujing to determine sensory quality, appearance quality, physical characteristics and chemical composition of tobacco leaves. ArcGIS was used to analyze the spatial distribution of sensory quality of Qujing tobacco leaves, and the effects of appearance quality, physical characteristics and chemical composition on sensory quality were explored by random forest and other methods. The results showed that the overall sensory quality of tobacco leaves in Qujing tobacco-growing regions was good, but there were spatial differences. The variation was parabolic from north to south, the east-west trend was an inverted “U” shape, both sides were low and the middle was high. Correlation analysis showed that color, chroma, total sugar, reducing sugar and potassium oxide had significant positive correlations with sensory quality. Leaf weight, filling value and total nitrogen were negatively correlated with sensory quality. The random forest model was used to analyze the contribution degree of each index to sensory quality of tobacco leaves. The degree of influence on sensory quality from strong to weak was total sugar, reducing sugar, total nitrogen, potassium, and chroma. In summary, there were spatial differences in sensory quality of tobacco leaves in nine tobacco-planting counties in Qujing City, which could provide reference for the selection of characteristic raw materials for industrial enterprises. The reason for the difference may be related to the changes in the contents of total sugar, reducing sugar, total nitrogen and potassium in tobacco leaves. Therefore, it was suggested that the contents of total sugar, reducing sugar, total nitrogen and potassium in tobacco leaves should be controlled by directional technology to optimize or stabilize the sensory quality of tobacco leaves in Qujing City.
