The invention discloses a method for predicting the total nitrogen content and the sugar-alkali ratio after tobacco leaf curing, and the method comprises the steps: predicting the total nitrogen content after tobacco leaf curing: building a prediction model of the chemical component content of fresh tobacco leaves and the total nitrogen content of the cured tobacco leaves, detecting the total nitrogen content of the fresh tobacco leaves in the harvesting period, and substituting the total nitrogen content into the prediction model, outputting the total nitrogen content of the flue-cured tobacco leaves; and predicting the sugar-alkali ratio of the flue-cured tobacco leaves: establishing a prediction model of the chemical component content of the fresh tobacco leaves and the sugar-alkali ratio of the flue-cured tobacco leaves, detecting the starch content and the total nitrogen content of the fresh tobacco leaves in the harvesting period, substituting the starch content and the total nitrogen content into the p
