1. Choose buds. Sprouts should be selected from the middle of the scion. The upper buds and the lower buds should not be used. Bud size should be appropriate. If it is too small, the contact surface with the rootstock is small, and it is difficult to survive; when it is too large, it is easily detached when it is inserted into the incision of the rootstock, causing poor contact and reducing the survival rate.
Special attention should be paid to the fact that the sprouts must have vascular bundles (commonly known as bud pads), which are the pathways for the communication of moisture and nutrients between the sprouts and the rootstocks. If they do not, it is difficult to survive. Therefore, when cutting the buds, care should be taken to take a small amount of xylem, and budding can generally be used as a shield or ring block. Such as the shield-shaped buds length of about 1.5 to 2 cm, ring block shape as the rootstock and bud size flexible grasp.
2. Grafting method. When grafting, we must first select the rootstocks so that we can pick them side by side. Long-range harvesting (buds) should pay attention to moisture. Buds and more use of "D" shape or ring two methods. If "D" shaped buds are used, the roots and necks of 3 to 5 cm from the ground shall be cut into "T" shape, and the depth shall be such as to see the xylem, and the bark can be stripped. Then cut into the shield with a pedicel with buds carefully peeled off the rootstock "T"-shaped bark at the place, promptly quickly embedded buds, tied tightly, only exposing buds and petioles. After cultivating the rootstock, the rootstock was cultivated 10 centimeters high and 10 to 15 days old. The survival rate was checked. If the buds are fresh and light green, the petioles touch and fall, indicating that they have survived. For unfilled ones, they should be reconnected on the back surface of the rootstock. The seedlings that are budded in the autumn of last year should be 18 to 20 centimeters after the buds are in the spring. At the interception (ie live pile), untie the tie. Three or four prunings in the summer, cutting off new branches on the rootstock. When buds reach a new height of 8 to 10 cm, they should be tied to the living column near the base to prevent breakage. When they grow to 20-25 cm, they are tied again at the upper end until they are newly grafted into lignified wood. Living column. New seedlings can continue to stay in Daejeon to grow large seedlings.
3. Note. The key to whether budding can survive or not is that the forming layers of both sprouting and rootstocks should be in close contact with one another to make them heal firmly. Therefore, the knife should be fast, the cut surface should be smooth, and it should be tied tightly when dressing. The width of the dressing should be 1~1.5 cm above and below the interface. It is advisable not to injure the bud during the operation, and to loosen after the bud has survived.
