Regional distribution and analysis of climatic characteristics of light-sweet flavor style of flue-cured tobacco in Wumeng tobacco-growing areas
摘要
Abstract
The tobacco leaf samples collected from 87 villages and towns in Wumeng tobacco-growing areas were determined,while the meteorological data of nearly 40 years were collected.Analyzing the major meteorological data in term of sunshine,temperature and rainfall,we identified the climatic characteristics of light-sweet flavor style of flue-cured tobaccos.The results showed that Wumeng tobacco-growing areas were provided with a relatively high altitude,an adequate sunshine duration and rainfall,while its average temprature was lower.Variabilities of optothermal indexs were weaker,but variation amplitudes of some rainfall indexs were bigger,which might be the key factor affecting the quality of Wumeng flue-cured tobaccos.According to the aroma scores,light-sweet flavor style of fluecured tobaccos in Wumeng tobacco-growing areas could be divided into three subtypes:typical lightsweet flavor style,light-sweet flavor style,and weak light-sweet flavor style,of which typical lightsweet flavor flue-cured tobaccos had good aroma quality including rich aroma volume,exquisite,soft and fruity smoke,less offensive and irritating odor,clean and comfortable aftertaste.With light-sweet flavor style enhancing,altitudes were higher and higher,heat indexes gradually reduced,and the differences of the heat indexes in different subtypes were highly significant.Typical light-sweet flavor tobacco-growing areas had the most sunshine durations during transplanting and vigorous growth periods and weak light-sweet flavor tobacco-growing areas had the minimum,while sunshine durations during the root extending period,maturing period and field period showed the contrary trend.In addition to the rainfall of mature period,other rainfall indexs among the three subtypes existed significant differences and with light-sweet flavor style enhancing,rainfall during growth and development period presented the increasing tendency.关键词
