One, bridging method. Cut a robust shoot with one end connected to the upper part of the sickle and one end to the lower part of the sickle. Use the shoot as a bridge to allow the nutrient to be cleared. The bridging time is generally best when the bark is easily peeled off in March and April of spring. Other times can be performed at any time as long as it is peeled off. Scion to choose full, healthy nutrition branches, with a small country light best annual branch. Remove the blade. The length of the shoots is determined by the size of the sickness. Scion should be used with it. Grafting method: 1, rootstock processing. Scrape and cure all the rot disease skin clean, coated with disinfectant and then grafting. When grafting, first in the lower part of the disease from the lower edge of the disease 5 cm, with a knife cut a "T"-shaped incision, about 3 cm in length, deep to the xylem, the incision cortex opened. Then, in the upper part of the sickle, an incision of the same size is engraved at a distance of 5 cm from the top edge. 2, scion processing. The required length of the scion, in the same plane at both ends of the scion, cut into a horse-shaped noodles with a sharp knife, the cut surface should be smooth and flat, and the length is similar to the stock “T⊥†incision. Do not use scion. 3, bonding. After cutting the scion, insert the “T⊥†incision of the rootstock at the fastest speed so that the cuttings and the formation layer of the branches stick together. After plugging in, use a small nail to fasten the center of the scion and the joint of the rootstock. A wax or clay cow dung protectant is then applied. The branches are slightly bowed. Branches with large branches of rot disease can be bridged by multiple branches. Second, the foot connection method. It is to use the sprouts of the roots of the diseased tree or the branches from the lower part of the disease to scion, connect the top of the tree to the upper part of the disease, and pass the branches to clear the upper and lower nutrients. Foot connection time is the same as bridging, as long as skinning is possible at any time. In addition to the use of root seedlings and branches of 1 to 2 years old, it is also possible to use green branches that have been wooded in the past without removing the leaves. After bridging and connecting, check it at any time.
