A method for preparing sun-cured tobacco by irradiation, includes the following steps: (1) soaking dried fresh tobacco leaves in water for a period of time and then sun-drying the soaked tobacco leaves; (2) evenly spraying a pretreatment solution on surfaces of the soaked and dried tobacco leaves, sealing, and letting them ferment naturally for a period of time; (3) sun-drying the fermented tobacco leaves again; (4) irradiating the sun-dried tobacco leaves with a certain dose of gamma () rays; and (5) aging and maturing the irradiated tobacco leaves under certain conditions to obtain the sun-cured tobacco. The sun-cured tobacco obtained by the method can be used to improve the smoke quality of cigarettes.
