Abstract：To find out the effects of combinations of key temperature lasting time with humidity in bulk curing barn on the quality of flue-cured tobacco from different producing areas, the tobacco leaves from Pingdingshan and Dali producing areas were respectively treated with different combinations of key temperature lasting time with humidity in a down-draft bulk curing barn.Then the pigments, chemical compositions, appearance quality and economic benefit were detected and analyzed.The results showed that under the T3 treatment, the flue-cured tobacco from the two producing areas had better chemical compositions, coordination, appearance quality and economic benefit.Under the T4 treatment, the leaves had a lower pigment content.Under the same treatment, the pigment contents, chemical compositions, coordination, economic traits and appearance quality of flue-cured tobacco from two areas had great differences.The flue-cured tobacco from Dali had characteristics of slightly higher carotenoid content, higher average price and less energy consumption.The flue-cured tobacco from Pingdingshan had better appearance quality and more appropriate chemical composition.Therefore, T3 treatment, which was under the temperatures of 38℃ (35±0.5℃) lasting for 18 hours, 42℃ (36±0.5℃) for 16 hours, 47℃ (37±0.5℃) for 12 hours and 54℃ (38±0.5℃) for 12 hours, was beneficial to improve the quality of flue-cured tobacco and cut down the energy consumption.
