Then cut the cortex of the rootstock to the xylem according to the length of 3-4cm and the width of 2cm in the straight and smooth part.

Bandage: wrap the buds tightly with wide 2cm plastic strips from bottom to top, and the buds are exposed.

After that: about 10 days to check survival, the sign of survival is petiole shedding or bud sprouting, and timely replacement of those who did not survive. Remove the sprouts from the rootstocks to promote budding, usually once in about 10 days.

Unbind: when the new tip of the graft grows above 5cm, it can be untied. Unbinding too early or too late can affect growth.

Pick the heart: when the new tip of the graft is about 30cm, pick the heart in order to survive the winter safely.

Disinfestation: if the occurrence of wood inchworm, diamondback moth and other insect pests, can be used to kill 2000 times liquid for treatment.

Cold protection: walnut field grafting needs to survive the winter and prevent cold in the same year. Before the soil is frozen, the overpowering soil can be buried to prevent cold, and the plastic film that cannot be buried to prevent cold can be used to wrap it. The next spring sprouting period is timely unearthed or unwrapped.
