The invention discloses a temperature stabilizing and humidity reducing dense flue-cured tobacco curing method. The dense flue-cured tobacco curing method comprises a temperature stabilizing and humidity reducing yellowing stage, a temperature stabilizing and humidity reducing color fixing stage and a temperature stabilizing and humidity reducing killing-out stage. The method disclosed by the invention can reduce a wet bulb temperature step by step by stabilizing tobacco leaf yellowing, color fixing and killing-out appropriate temperatures, so that a curing target of mutual coordination between tobacco leaf yellowing and water loss, between color fixing and aroma enhancement and between killing-out and aroma maintenance is achieved in a curing process; a yellow flue-cured tobacco rate is improved to a greater extent, and tobacco leaf quality is improved. The method disclosed by the invention has the advantages of simpleness and easiness in operation control.
