The embodiment of the invention discloses a tobacco leaf baking method. By means of the tobacco leaf baking method, tobacco leaf baking quality is improved, coal is burnt more sufficiently, coal consumption is greatly reduced, the tobacco leaf baking cost is lowered, and adverse effects on the environment are avoided. The tobacco leaf baking method comprises the steps that at the earlier stage when tobacco leaves turn yellow, coal cinder is added before ignition and overspread the middle of a hearth, and 5-10 kg of coal accounting for 1/4 of the area of the hearth is initially added into the hearth, wherein the thickness of the coal layer ranges from 5 cm to 10 cm; at the stage when the tobacco leaves turn yellow, coal accounting for 1/4-1/3 of the area of the hearth is added each time; at the stage when branch veins turn yellow, coal accounting for 1/2 of the area of the hearth is added each time; at the stage when main veins turn yellow, coal is added till the hearth is full each time, so that dry-bulb temperature rises to 45 DEG C to 48 DEG C at the speed of 1 DEG C/2-3 h, and wet-bulb temperature is controlled within the range from 37 DEG C to 38 DEG C; at the stage when aroma substances are synthesized, coal is added till the hearth is full each time, so that the dry-bulb temperature is kept within the range from 52 DEG C to 54 DEG C, and the wet-bulb temperature is controlled within the range from 38 DEG C to 40 DEG C; at the killing-out stage, coal accounting for 2/3 of the area of the hearth is added each time, and the area of added coal is decreased gradually till baking is finished.
