Comprising the steps of harvesting, aroma enhancement fungicide treatment, furnace charging, a yellowing period process, a color fixing period process, a stem drying period low-temperature aroma keeping process and aroma keeping and moisture regaining treatment. In the whole moisture regaining process, high temperature and high humidity are kept, air in a curing barn is kept high in water potential, along with temperature reduction, outer-layer tobacco leaves sufficiently retain water and absorb moisture, moisture rapidly permeates inwards, the effect of rapid moisture absorption and moisture regaining is achieved, the tobacco leaves sufficiently absorb moisture, main tendons and veins become soft, and therefore the contracting and stretching effect is good, and the tobacco leaf moisture regaining effect is good. The appearance quality is high, and the tobacco leaf quality is greatly improved.
