Management method for grafted walnut tree

The invention relates to a management method for a grafted walnut tree and belongs to the field of fruit tree grafting management. The method includes the steps that within 25d-35 d after the walnut tree is grafted and survives, a plastic film on a grafting wound is removed, and the grafting wound is bound with newspaper; after grafting is completed, when a shoot of a scion grows to 20-50 cm, a top end growth part of the shoot is cut out, after an axillary bud of the shoot germinates to form a secondary shoot, the axillary bud is cut out from a stem base, the apical dominance of the scion shoot can be reduced to a certain degree, a newborn branch of the scion grows more vigorously, branches scrambling for nutrients are reduced, the grafted tree vigor restores robustness as soon as possible, the grafting wound rapidly heals, the secondary repairing and linking labor and material expense cost generated by grafting failure is reduced, the phenomenon that a current-year shoot is easily swabbed off when encounteri
