The invention provides a post-disaster remediation method for hail damage of flue-cured tobaccos. The post-disaster remediation method comprises the steps: (a) clearing a bamboo field, cleaning a ditch to drain water, retaining branches in the bamboo field, and applying a pesticide; not retaining branches of flue-cured tobaccos at a root elongation stage under the conditions of light, moderate andsevere disasters; and for flue-cured tobaccos at a resettling stage, not retaining branches under the condition of the light disaster, retaining top branches under the condition of the moderate disaster, and retaining bottom branches under the condition of the severe disaster; (b) spraying a foliage fertilizer on leaf surfaces of the flue-cured tobaccos; (c) applying a flue-cured tobacco recoveryfertilizer, and applying rooting powder; (d) selecting and retaining branches of the flue-cured tobaccos, and removing other axillary buds; and (e) carrying out intertillage and hilling, and applyinga flue-cured tobacco growth fertilizer. The remediation method provided by the invention is used for realizing targeted remediation such as branch retention and fertilizer application on the flue-cured tobaccos which are in different growth periods and suffer from different degrees of hail damage, so that the yield of the flue-cured tobaccos is increased, and the quality of the flue-cured tobaccos is improved.
