Abstract: In order to evaluate the feasibility of biomass energy curing and improve the evaluating system of the appearance quality of flue-cured tobacco,tobacco leaves samples from biomass energy curing areas in Yunnan were used as materials to construct an evaluation system for the appearance quality of biomass energy cured tobacco by utilizing expert consultation,descriptive statistics,variance analysis,cluster analysis and geo-statistical analysis,and the correlation of the indexes of the evaluation system of appearance quality and regional characteristics of appearance quality of flue-cured tobacco with biomass energy in Yunnan were analyzed.The results indicated that there was a very significantly positive correlation among maturity,growth status,leaf structure,body,oil,chroma,chromatic homogeneity,smooth or green-yellow of the evaluation indexes of appearance quality of biomass energy flue-cured tobacco in Yunnan.Its maturity was closely related to other indexes,while leaf structure had little influence on other indexes.The scores of appearance quality of different grades of tobacco leaves were X2F<B2F<C3F,the difference was very significant,and the scores of appearance quality of different varieties of tobacco leaves were Yunyan 87<K326<Hongda.The high value of tobacco appearance quality index appeared in tobacco planting areas of the central Yunnan,and gradually decreased in the surrounding areas,with obvious spatial trend.The tobacco planting areas with high tobacco appearance quality index mainly concentrated in Chuxiong,Kunming and Yuxi.The quantitative evaluation system of appearance quality of biomass energy flue-cured tobacco is relatively reasonable,and it is feasible to evaluate comprehensively the appearance quality of biomass energy cured tobacco in Yunnan.
