Comprising the following steps that a closed hot air circulation curing barn is built, and an alcohol-based fuel or biomass fuel burner is additionally arranged for direct heat supply. On the basis of ventilation and dehumidification equipment of an existing open type hot air circulation curing barn, in the stem drying period of the curing process of flue-cured tobacco leaves, an air inlet door and a dehumidification window are sealed, and hot air circulates in the curing barn; on the basis of an existing heat source curing barn, a 30-40 kW alcohol-based fuel or biomass fuel burner is additionally arranged, heat is directly supplied to a hot air circulating system of a heat supply chamber, a large amount of CO2 generated after fuel combustion is input during heat supply, the concentration of CO2 is 0.080%-0.100%, CO2 and H2O are combined to form gaseous H2CO3 to be discharged, and tobacco leaves are rapidly dried.
