The invention discloses a curing method suitable for curing K326 tobacco leaves in a movable curing barn and obtained tobacco leaves. The flue-cured tobacco leaves are obtained through the charging period, the yellowing period, the color fixing period and the stem drying period. Aiming at the fact that K326 tobacco leaves are baked by using a movable curing barn, baking parameters of the yellowing period, the color fixing period and the stem drying period are comprehensively regulated and controlled, the wet bulb temperature and the temperature stabilizing time of the curing barn are regulated and controlled in the whole baking period according to the tobacco leaf curing state, and particularly a plurality of temperature nodes are designed in the three stages of the yellowing period and the early stage of color fixing. The color of the tobacco leaves is gradually and controllably changed, the color change of the tobacco leaves is coordinated with the water loss, the tobacco leaves are prevented from yellowing or excessive yellowing, flue-cured tobacco such as ash hanging and dry tobacco caused by too high moisture of the tobacco leaves during later heating is avoided, meanwhile, the flue-curing time of the yellowing period and the color fixing period is properly prolonged, conversion of content substances of the tobacco leaves is promoted, and the quality of the tobacco leaves is improved. According to the curing method, high-quality K326 tobacco leaves can be cured by using the movable curing barn, and the curing method has great significance in subsequent further popularization of the movable curing barn.
