The invention discloses a flue-cured tobacco topping method. The flue-cured tobacco topping method is characterized in that in a topping process, useless leaves and inflorescences at the upper parts of tobacco plants are removed and useful leaves are kept; and meanwhile, at least two sections of stems at the upper ends of the useful leaves are kept. According to the flue-cured tobacco topping method disclosed by the invention, tender stems at the tops of the tobacco plants are remained, so that the tender stems at the tops of the tobacco plants are organized together to realize certain apical dominance effect, and furthermore, the growth potential of the tobacco plants can be automatically adjusted, the nicotine and special leaf weight of upper leaves are reduced and the sensory quality of the upper leaves is improved.
