First, promote the long branch of the wound surgery. About 40 days before germination, in the apple and pear trees on the tree root, the long branches need to be promoted. A small saw blade is used to cut a horizontal hole less than 1 mm above the bud, and the cut edge is slightly deep into the xylem. It takes 10-15 days after flowering. Then, in summer girdling on the damaged branches, the long branches can be promoted and the branches can be cultivated to overcome the baldness and dislocation of the branches.
Second, to promote the middle and short branches of incisional surgery. (1) A few days before germination, at the site where the short shoots need to be promoted, a small hacksaw blade is used to cut a horizontal mouth at 1-3 mm above the shoot to cut through the cortex as a degree, not into the xylem, and 5 days after flowering. The girdling was performed on the damaged branches. (2) For the long branches cut in winter, put in a few days before the budding in the spring, each small bud on the long branch is cut one by one with a small steel saw blade, so that upward nutrient resistance, nutrient dispersion, can promote a large number of Short branches without long branches. The long branches that have been laid slowly have produced a large number of fruiting branches after spring injury and summer girdling.
