Flue-cured tobacco cultivation management and baking methods for relieving cold damage on basis of potassium dihydrogen phosphate and cane sugar

The invention discloses flue-cured tobacco cultivation management and baking methods for relieving cold damage on the basis of potassium dihydrogen phosphate and cane sugar. The management method comprises the following steps: identifying tobacco plants suffering from cold damage; spraying 0.1-0.125 wt% of the potassium dihydrogen phosphate and 0.3-0.37 wt% of the cane sugar onto the tobacco plants suffering from light cold damage, 0.15-0.2 wt% of the potassium dihydrogen phosphate and 0.45-0.8 wt% of the cane sugar onto the tobacco plants suffering from medium cold damage, and 0.3-0.4 wt% ofthe potassium dihydrogen phosphate and 0.9-1.2 wt% of the cane sugar onto the tobacco plants suffering from heavy cold damage; 2-3 days after spraying, identifying the tobacco plants again; and spraying 0.08-0.115 wt% of the potassium dihydrogen phosphate and 0.24-0.345 wt% of the cane sugar onto the tobacco plants suffering from light cold damage, and 0.125-0.18 wt% of the potassium dihydrogen phosphate and 0.375-0.54 wt
