The invention relates to a preparation method of top six tobacco leaves, which is characterized in that the labor intensity can be alleviated, and the accurate baking measures are adopted for guaranteeing the quality of the top tobacco leaves. Aiming at the phenomenon that for the existing one-time harvesting and baking for the top six tobacco leaves of flue-cured tobacco, the perfect production and technical guidance is not available, so that the quality of the top tobacco leaves can not be sufficiently demonstrated, the method provided by the invention emphasizes the accurate harvesting of the top six leaves, the classification of fresh tobacco leaves and accurate baking of the flue-cured tobacco, then the vacancy of the production system of the top six leaves of the flue-cured tobacco is made up, the existing problems including poor maturity after baking, leaf stiffness, poor filling ability, strong varicolored property, greenness at the base part and the like are solved, and the purpose of sufficiently demonstrating the quality of the top leaves of flue-cured tobacco is achieved.
