The method comprises the steps that fresh flue-cured tobacco leaves which are well-done are harvested and woven into rods or loaded into tobacco clamps and then put into a curing barn; the tobacco leaves are subjected to the steps of yellowing stage, color fixing stage and stem drying stage control and moisture regaining treatment and impurity gas removal treatment baking in sequence, and then the adjusted heating cigarette tobacco leaves can be obtained. The tobacco leaves are obtained through the method. The application is application of the tobacco leaves obtained through the preparation method in preparation of heating cigarettes. According to the method, based on the preparation characteristics and re-baking technological processes of heating cigarette raw materials, the primary baking technological process and the re-baking technological process of the tobacco leaf raw materials are optimized and combined, the re-baking and impurity gas removal process is completed in the primary baking stage in advance, the problems that a heating cigarette tobacco leaf production line is tedious and solidified, and a large amount of manpower and a large number of material resources are needed in the industrial re-baking process are solved, the quality requirement of the heating cigarette tobacco leaf raw materials can be met, the tobacco leaf fragrance amount can be increased, optimization of a heating cigarette production chain is promoted, and the production efficiency is effectively improved.
