Before the spring fruit tree sprouts, injuring above the bud can increase the germination power and achieve the purpose of stimulating branch shoots. However, in the process of dicing, there are many differences in the technique of accelerating the long-branching technique and the technique of inducing the short-branching of the middle and short branches.

1. To promote long-shaft incisional surgery. About 40 days before germination, in the apple tree and pear tree, it is necessary to promote the long branch. Use a small hacksaw to cut a horizontal hole less than 1 mm above the bud. Cut the mouth slightly deep into the xylem. 10-15 after flowering. Days, then summer girdling on the cut branches, can promote long branches, cultivate the backbone branches, to overcome the bare baldness and disconnection phenomenon.

2. Facilitate the incisional surgery of short and middle branches. For the long branches cut in winter and slowly, each bud on long branches was scratched one by one above the buds a few days before the budding in the spring, making upward nutrient resistance, nutrient dispersion, and can promote a large number of short and medium Branches without long branches. Specific measures are: a few days before germination, in the need to promote short-stem branches, 1 to 3 mm above the bud, with a small hacksaw cut a horizontal mouth, to cut through the skin as a degree, not in-depth xylem, and flowers The girdling was performed on the damaged branches five days later.
