　　Abstract： The experiment was conducted to solve the insufficient degradation of dry matter and inadequate aroma matter in flue—cured tobacco leaf in application of bulk—curing barn. K326 was used as the material in experiment， and the effects of different wet bulb temperature of key temperatures in bulk—curing barn on physical characteristics and chemical constituents of flue—cured tobacco leaf were evaluated in Liuyang city of Hunan province. The results indicated that the humility in yellowing period and color fixed period had an important influence on physical characteristics and chemical constituents of flue—cured tobacco leaf. Properly increasing humility in yellowing period and color fixed period could greatly improve the quality of flue—cured tobacco leaf. When dry bulb temperature was 38 ℃，wet bulb temperature was properly controlled at （36±0.5） ℃ of upper tobacco leaf， at （35±0.5） ℃of middle tobacco leaf， at （36±0.5） ℃ of lower tobacco leaf， respectively. When dry bulb temperature was 42 ℃，wet bulb temperature was properly controlled at （38±0.5） ℃ of upper tobacco leaf， at （37±0.5） ℃ of middle tobacco leaf， at （37±0.5） ℃of lower tobacco leaf， respectively. When dry bulb temperature was 45 ℃ or 47 ℃，wet bulb temperature was properly controlled at（38±0.5） ℃of upper tobacco leaf， at （39±0.5） ℃ of middle tobacco leaf， at （38±0.5） ℃ of lower tobacco leaf， respectively. When dry bulb temperature was 54 ℃，wet bulb temperature was properly controlled at（40±0.5） ℃ of upper tobacco leaf， at （40±0.5） ℃ of middle tobacco leaf， at （39±0.5）℃ of lower tobacco leaf， respectively.
