Fruit trees spring branches three methods
Branch grafting is the grafting method using the shoots of the plant as the scion. Branching is generally performed when the sap begins to flow in the spring, the cortex has not yet been exfoliated, or when the rootstock peels but the scions have not yet sprouted. Commonly used grafting techniques include cutting, splicing, splicing, tongue-jointing, etc. Now, the cutting, splicing, and tongue-jointing are introduced as follows.
Pharmaceutical excipients refer to excipients and additives used in the production of drugs and formulating prescriptions; in addition to the active ingredients, they are substances that have been reasonably evaluated in terms of safety and are included in pharmaceutical preparations.Pharmaceutical excipients are the basic materials and important components of pharmaceutical preparations, which are the material basis to ensure the production and development of pharmaceutical preparations, and play a key role in the formulation and production of pharmaceutical preparations.It doesn't just give drugs a certain dosage form.Moreover, it has a great relationship with improving the curative effect of drugs and reducing adverse reactions.

First, cut 1 apply: cut for root neck 1-2 cm thick rootstock for ground grafting. 2 Scion cutting: Scion cut into 5-8 cm long, with 3-4 buds, cut the scion into two noodles, one long and one short, the long bevel is 2-3 cm long and cuts back to the back. A small incline less than 1 cm makes the wedge below the scion flat. 3 Rootstock processing: Cut the rootstock 4-6 cm from the ground. The side of the selected root veneer was thick and smooth with a knife. The knife was cut perpendicularly at the place where the xylem was slightly inside the section of the skin. The depth was slightly shorter than the long bevel of the scion, and the width was equal to the diameter of the scion. 4 Joining: Put the scion into the cut side and insert it into the cut of the rootstock. Make sure that the scion is aligned with the rootstock forming layer. If it cannot be aligned on both sides, align the side. 5 Bundle: Use hemp or plastic strips, etc., and apply sealing wax. Apply wet ripping from the bottom up and scoop 3-4 cm above the scoop.
Second, the skin graft 1 Application: The use of skin graft is a commonly used method of grafting, mostly used for high-replacement head, the method is simple and rapid operation, this method must be in the case of sprouting rootstock, peeling can be used . 2 Scallion cut: Cut the scion into 3-5 cm long noodles. If the scion is thick, cut the noodles should be longer. Cut a small cut surface of about 1 cm on the back of the long noodles to sharpen the lower end to form a wedge. The 2-3 buds are reserved for the scions, and the top buds are left to face each other. The thickness of the scion is usually 0.3-0.5 cm. The specific thickness should be determined according to the thickness of the scion and the species. 3 Rootstock processing: Any rootstock with a diameter of 10 cm or more can be inserted into the skin. Select the appropriate height on the rootstock. Select a smoother part to cut off or cut off. The section should be vertical to the branch, and the section should be cut with a knife. To heal. 4 Joining: Select a smooth and curved part on the flattened rootstock, draw a longitudinal incision slightly shorter than the cut noodles through the skin, and reach deep into the xylem. Use the knife to gently stir up both sides of the incision with a knife and put the scion. In the center of the cortical interface, the long section faces the xylem. The xylem is inserted between the xylem and the cortex of the rootstock.
