How are walnut trees grafted?

How are walnut trees grafted? Please introduce the grafting methods of walnut trees for reference: split grafting is suitable for rootstocks with older age, thicker stem (more than 4 cm in diameter) and big trees. The rootstock of choice. Cut off 30 cm from the base of the stock, cut the saw, cut it vertically in the middle of the rootstock with a knife, about 5 cm deep, cut a symmetrical slope on each side of the scion, 4 cm long, and then quickly insert the scion into the split of the rootstock, so that the scion slope exposed 3 cm 7 cm, and make the rootstock form a close match. If the scion is thinner than the rootstock, the outer cambium should be aligned, the inner side of the scion should be retained, and then tightly bound with plastic strips to maintain interface humidity to facilitate healing. This grafting method is suitable for early grafting, and the cortex of the rootstock is not separated from the cortex. This method is suitable for tender young trees of 3 cm to 5 cm. After it is easy to leave the skin, the white and smooth place is sawed off, the saw is flattened, and the old skin is cut off at the scion, which is 5 cm in length and 1 cm in width, exposing the cortex. Cut the scion into a 6-8 cm long cutting surface, which is deeper than the pith, and then cut obliquely to ensure that the whole inclined plane changes from thick to thin, pinch the cortex behind the cutting surface with your fingers to separate it from the xylem, then insert the xylem of the scion between the xylem and the cortex of the rootstock, so that the cortex of the scion is covered on the cutting surface of the cortex of the rootstock, and finally tie the interface with plastic strips. Pay attention to not watering before, or 10 days before sawing off the rootstock to release water, in order to avoid excessive bleeding to reduce the survival rate.
