The invention relates to a eucommia debarking method, in particular to a eucommia debarking promoting method and a new eucommia bark growth promoting method. The eucommia debarking promoting method and the new eucommia bark growth promoting method comprise the following steps: firstly, measuring a eucommia tree needing to be debarked by a thickness gauge to measure the bark thickness; then horizontally cutting an upper cut and a lower cut on the eucommia tree in the trunk direction through an art knife or a budding knife sterilized by alcohol, wherein the interval of the upper cut and the lower cut is 50-100 cm; perpendicularly cutting cuts on the edges of the two horizontal cuts; then upwarping the bark at the cut hinge parts in the horizontal direction through a knife handle; uniformly pulling the bark downwards with hands until the bark falls off from the tree body; finally spraying a layer of nutrient solution on the debarked part; coating with an air permeable plastic film; unwrapping the plastic film a month later. Through the adoption of the eucommia debarking method, the debarking is convenient, the debarked part is sanitary, and the survival rate of eucommia is improved.
