The present invention discloses a flue-curing method for reducing ash on upper tobacco leaves. The method shortens the yellowing time at or before 38°C, maintains the same dry-bulb and wet-bulb temperatures at 40°C, stops the circulating fan, reduces the temperature and humidity difference between different tobacco layers in the flue-curing barn, then lowers the wet-bulb temperature. This process is repeated to cause the tobacco leaves to soften, wilt, and turn yellow. The dry-bulb temperature is then raised to 44°C, causing the main ribs to soften. The high temperature is then returned to 42°C, and the wet-bulb temperature is lowered by 1-2°C at 42°C to control the water loss of the tobacco leaves to 40-45%, inhibiting the activity of polyphenol oxidase and promoting yellowing. The dry-bulb and wet-bulb temperatures are then lowered by 1-2°C at the initial color setting stage, slowing the heating rate. A medium temperature, medium humidity, and slow heating are used for color setting in the middle color setting stage. The temperature is then slowly increased in the later color setting stage. The flue-curing time at a steady temperature of 54°C is extended to increase the water loss and dryness of the tobacco leaves. The wet-bulb temperature is increased during the dry rib drying stage. This method can significantly reduce the occurrence of ash on tobacco leaves and improve the appearance quality of the upper tobacco leaves after curing.
