Abstract: 【Objective】The study was conducted to improve the phenomena of barn rot and mildew during aircuring process in alpine tobacco area and raise the air-curing quality of burley tobacco.【Method】A control experiment was conducted among four air-curing modes: simple arched air-curing shed, simple arched heating air-curing shed,“89”heating drying room and“89”standard drying room（CK）.【Result】The effects of simple arched air-curing shed and simple arched heating air-curing shed on the average temperature and relative humidity control during air-curing process were better than those of“89”heating drying room and“89”standard drying room. The simple arched heating air-curing shed mode had the highest economic enefits, with yield improved by 12.35%, output value increased 8433.90 yuan/hm2, rate of high and middle quality tobacco raised by 7.82% and proportion of tobacco mildew reduced to 4.09%. The simple arched air-curing shed mode had lower economic benefits than those of simple arched heating air-curing shed mode, the tobacco mildew rate could be controlled at 4.17% by such mode.【Conclusion】Considering the economic benefits and cost inputs of the four aircuring modes, simple arched air-curing shed and simple arched heating air-curing shed were more suitable for the air-curing requirements and sustainable development of burley tobacco in alpine tobacco areas.
