The method comprises the steps of leadingthe outlet end of an oxygen pipe capable of introducing oxygen to an air inlet in a bulk curing barn, and releasing the oxygen at intervals at the early stage of tobacco leaf curing and yellowing, soas to promote the tobacco leaf yellowing, shorten the tobacco leaf yellowing period and shorten the time of the whole curing process. The device comprises the bulk curing barn, an oxygenation deviceand the oxygen pipe; an outlet of the oxygenation device is connected with the oxygen pipe; and the oxygen pipe penetrates into the bulk curing barn, and the outlet end of the oxygen pipe is led to anair inlet in the bulk curing barn so as to oxygenate the curing barn in the earlier stage of tobacco leaf curing and yellowing. The method and the device are beneficial to shortening the yellowing period of the tobacco leaves and shortening the total curing time, easy to implement and simple and convenient to operate.
