[目的]为了掌握典型清香型烟区烤烟品质与主要生态因子之间关联度,为烟叶生产提供理论支撑.[方法]通过采集典型清香型烟区烤烟样品和收集相关地点气象资料,应用灰色关联原理分析典型清香型烟区烤烟化学成分和感官质量评吸与气象及土壤因子之间关联度.[结果]①宁洱、会理、红塔均温在烤烟生育期均前期上升后期略有下降;平均相对湿度生育期先增加后稳定;降雨量均在成熟中期达到最大,3个地方降水均呈现前少后多状态;前期日照充足后期较低,3个地方均在成熟前期达到日照最低值;温差均呈现先下降后略有上升的状态.②阳离子交换量与总糖和还原性糖、盐分和烟碱灰色关联最高,有效硼与烟叶中氯最高,有效铁与烟叶中钾灰色关联最高,氯与淀粉含量灰色关联最高;有效硼与烟草本香、香气量、香气质、浓度、刺激性劲头、感官评吸总分均灰色关联度最高,杂气与土壤中水溶性氯关联度最高,干净度和湿润感均与有效磷关联度最高.③对于气象因子:总糖与温差灰色关联度最高,还原糖和淀粉与平均相对湿度关联度最高,烟碱、氯和钾均与日照时数关联度最高;浓度、刺激性、杂气、干净度及感官质量总分与平均相对湿度灰色关联度最高,烟草本香、香气质、回味等与日照时数关联度最高,香气量与均温关联度最高,湿润感与温差关联度最高.[结论]从气象因素上而言,本文选取的会理、红塔和宁洱三个地区均适合优质清香型烟叶生产,其中相对平均湿度和日照时数对烤后烟叶化学成分及烟叶感官评吸影响尤为明显;土壤因素中不同养分对于烤后烟叶及感官评吸影响具有差异,其中土壤有效硼影响显著.%[Objective]The present paper aimed to understand the correlation degree between the quality of flue-cured tobacco and the main ecological factors in typical flue cured tobacco-growing areas,and provide a theoretical support for tobacco production.[Method] Through collecting typical flue-cured tobacco samples related meteorological data were selected and the correlation between chemical composition and sensory quality of flue cured tobacco and meteorological and soil factors in typical tobacco growing areas by grey relational grade were analyzed.[Result] (i) For Ning'er,Huili and Hongta:the average temperature increased initially and then decreased slightly in the early stage of the growth period;the average relative humidity fertility rate increased and then stabilized;the rainfall amount reached the maximum in the medium of maturity;and the precipitation in the three places was more in the early growth period;in the early days,the early sunshine was low,and the three places reached the lowest sunshine in the early stage of maturity;the temperature difference showed a slight increase after the first drop;the average temperature were slighdy decreased in the early stage of the growth period of flue-cured tobacco;the sunshine was abundant in the early stage of the growth period,and the late stage of the growth period was low,and the lowest sunlight was reached in the early stage of growth;the temperature difference showed a slight increase in the state after the first rise.(ii) The grey incidence of Cation exchange capacity with total sugar,reducing sugar,salt and nicotine was the highest,effective boron and chlorine content in tobacco leaves,highest effective iron and potassium in tobacco leaves grey incidence was the highest,chlorine and starch content highest grey relation;Effective boron and tobacco aroma,concentration of aroma,sweet temperament,and stimulating momentum and sensory evaluation of grey correlation,the highest total score of mixed gas and the soil water soluble chloride,highest degree of clean and moist feeling with effective phosphorus highest correlation.(iii)The correlation between the total sugar and the temperature difference was the highest,and the correlation degree between the reducing sugar and the starch and the average relative humidity was the highest,and the nicotine,chlorine and potassium were the highest in the sunshine hours;the concentration,irritation,the correlation between the total score of sensory quality and the average relative humidity was the highest,and the correlation degree was the highest with the sunshine hours,the highest degree of aroma and average temperature,and the highest degree of wetness and temperature difference.[Conclusion] From the aspects of meteorological factors,the Hongta and Ning'er are suitable for the production of high quality flue cured tobacco leaves;the relative humidity and sunshine hours had a higher effect on the flue-cured tobacco leaves;and the effects of different nutrients on soils were different,and the effect of soil available boron was significant.
