Asexual propagation method for wild corylus mandshurica tree

The invention discloses an asexual propagation method for a wild corylus mandshurica tree, and belongs to the technical field of fruit tree asexual propagation. The asexual propagation method comprises the following steps that layering treatment is carried out on branches of a native plant; hormone treatment is carried out on the pressed branches to promote the branches to germinate and grow vertically to the ground; cutting slips are made by using newly germinated branches; a suitable rooting medium, a suitable rooting agent and a suitable bactericidal insecticide are adopted, and a full-illumination spraying cuttage technology is adopted to accelerate the rooting process. A method combining a horizontal layering technology and a full-illumination spraying twig cuttage technology is adopted, under the condition that an original stock plant superior line is not damaged, by utilizing the apical growth advantage, stock plant branches are horizontally pressed, so that more cutting slips with the apical advantage
