Quality Characteristics of Flue-Cured Tobacco and Key Meteorological Driving Factors in Southwestern Guizhou
摘要
Abstract
To elucidate the quality characteristics of flue-cured tobacco in southwestern Guizhou and its key meteorological driving factors,six major tobacco-producing counties in southwestern Guizhou were selected.Tobacco leaf samples and corresponding meteorological data were collected from 36 sampling sites.Using fuzzy mathematics,hierarchical cluster analysis,and partial least squares regression(PLSR)models,a comprehensive evaluation of regional tobacco quality was conducted,and the regulatory effects of key meteorological factors on the sensory quality of tobacco leaves were explored.The results showed that there were significant differences in tobacco leaf quality among the sampling sites.According to the comprehensive scores,the tobacco-growing areas could be divided into three categories,among which class Ⅰ,representing high-quality areas,was mainly distributed in the northwest and southwest regions.Excessive precipitation during the early growth stages(recovery and vigorous growth stages)inhibited the intensity and strength of cured leaves,while moderate precipitation during the maturity stage improved these traits but suppressed aroma expression.Sunshine duration significantly affected the sensory style of cured leaves:sufficient sunshine in the early stage favored the formation of intensity,whereas strong light from the vigorous growth to maturity stages tended to inhibit aroma expression.This study clarified the spatial pattern of tobacco quality in southwestern Guizhou and identified the key meteorological driving factors of sensory quality,providing a theoretical basis for optimizing the ecological zoning of flue-cured tobacco and developing high-quality production areas.关键词
