The invention discloses a baking method capable of improving the smoking quality of flue-cured tobaccos K326. The method specially comprises the following steps of harvesting, charging in stoves, yellowing, color fixation and killing-out. The problems of likely tobacco leaf yellowing, difficult color fixation, tobacco leaf stiffness after baking and insufficient aroma in the intensive baking process by controlling optimizing combinations of temperature, humidity and baking time, the first-class tobacco proportion, average price and the sensory smoking quality of baked tobaccos are effectively improved, and a technical support is provided for optimization of an adjustment and control technology adopted after intensive baking and yellowing.
