摘　　要：为完善、改进烟叶水分变化模型烘烤体系并提供相关数据支撑,研究密集烘烤过程中烟叶水分变化模型(Wang and singh模型)烘烤与常规烘烤条件下烤后烟叶的综合效益与品质。以江西吉安烤烟品种云烟87为试验材料,结合烘烤烟叶干燥程度7个阶段的经验失水量,利用Wang and singh模型数学公式推导,密集烘烤对烤后烟叶经济效益、等级结构、化学成分、感官质量进行分析。与常规烘烤相比,经济效益方面,模型烘烤可提高烤后烟叶产量60 kg/hm^2,增加产值2 500元/hm^2,提高均价0.48元/kg。等级结构方面,模型烘烤可显著增加橘黄烟比例5.55个百分点,提高上等烟比例4.52个百分点,减少低次等烟比例0.41个百分点。化学成分方面,模型烘烤可显著提高烤后烟叶总糖、还原糖含量和糖碱比,下部橘色2级(X2F)、中部橘色3级(C3F)、上部橘色2级(B2F)总糖含量分别增加6.06、2.63、2.48个百分点,还原糖含量分别增加3.01、2.82、2.55个百分点,糖碱比分别增加3.30、2.30、0.93;C3F、B2F化学成分协调性分别增加2.03、4.66分。感官质量分析方面,模型烘烤可提高烟叶香气质、香气量、浓度和劲头,模型烘烤X2F、C3F、B2F总分分别显著提高1.63、2.25、0.59分,协调性分别提高0.40、0.22、0.19分。Wang and singh模型烘烤烤后烟叶综合质量评价良好,可利用该模型在限定阶段失水量和烘烤时间的前提下实现烟叶精准烘烤。In order to perfect and improve the moisture changing model curing system of tobacco leaves and provide some relevant data support,the flue-cured tobacco leaf comprehensive benefit and quality by tobacco leaf moisture changing model(Wang and singh model)curing and conventional curing were studied.Tobacco variety Yunyan 87 in Ji’an,Jiangxi was chosen as the experimental material.Combined with the value of water loss at 7 stages during flue curing process,using Wang and singh model for mathematical formula calculation and derivation,the economic benefit,grade structure,chemical composition and sensory quality of flue-cured tobacco leaves were analyzed.Compared with the conventional curing,in terms of economic benefit,model curing could increase the yield of tobacco leaves by 60 kg/ha,increase the output value by 2 500 Yuan/ha,and increase the average price by 0.48 Yuan/kg.In terms of grade structure,model curing could significantly increase the proportion of orange yellow leaf by 5.55 percentage points,increase the proportion of first class leaf by 4.52 percentage points,and reduce the proportion of inferior leaf by 0.41 percentage points.In terms of chemical composition,model curing could significantly increase the total sugar,reducing sugar content and the value of reducing sugar/nicotine of flue-cured tobacco leaves,the second-level of orange lower leaf(X2F),the third-level of orange middle leaf(C3F)and the second-level of orange upper leaf(B2F)total sugar content increased by 6.06,2.63,2.48 percentage points,respectively;reducing sugar content increased by 3.01,2.82,2.55 percentage points,respectively;reducing sugar/nicotine value increased by 3.30,2.30,0.93 points.And the chemical composition coordination of C3F,B2F increased by 2.03,4.66 points,respectively.In terms of sensory quality,model curing could improve the score of fragrance quality,fragrance quantity,concentration and strength.Model curing could significantly improve the X2F,C3F,B2F total scores by 1.63,2.25,0.59 points,respectively,while sensory
