Leather joints

is also known as a skin joint. It is a kind of branching method which is easy to operate and easy to master. When used in woody plants, it can be carried out during the growth season when the sap flows (unlike the chopping and cutting methods), and the grafting steps are as follows:
(1) peeling the spike. Choose a spike with 2 to 4 full buds. After cutting its upper end flat, on the lower back of the lower bud, cut a knife into a smooth large slope about 3 cm long, and gently cut each knife on each side of the cutting surface, peeling off a trace of the cortical layer to reveal the formation layer inside. Then cut a small slope about 0.6 cm long on the back of the lower end of the large cut. Wrap the spare with a damm cloth.
(2) birch opening. Cut the birch 1 to 2 cm from the ground and flatten the section with a quick knife. Then, in the smooth part of the birch bark, cut vertically from top to bottom, deep into the woody part, about 1.5 cm long, and then use the tip of the knife to pick the bark apart. If the birch bark is tough, a wedge-shaped bamboo stick can be used to insert it down between the wood and the ligament, and then pull out the bamboo sign as the part where the spike is inserted.
(3) plug-in spike will be spike along the incision or bamboo sign insertion, inserted between the wood part and the tough skin part, smooth large bevel to face the wood part, the spike cutting surface and birch dense, generally 1 birch can be inserted on 1 to 2 spikes. Thick birch can be inserted into 3 to 4 pieces.
and burial of the skin is the same as the split and cut.
