(2) Pruning and smearing buds during the growth period: Around the cutting edge of the backbone branches, many buds are easy to germinate, except for 1-2 flat and oblique buds, all others are smeared. Thinning: Thinning branches that are too dense and too prosperous in June. Girdling and girdling: In June, measures such as girdling and girdling were taken for Wangshu and Wangzhi to temporarily control the downward transport of nutrients and make the upper branches form flower buds. Stripping the phloem of a branch is called girdling, and only a circle of phloem is cut; What is not peeled is called girdling. Turn the peeled bark upside down, embed it in the original peeling place, and bind it to heal. Core-picking: Core-picking the vigorous new shoots twice in mid-August and late August can promote lignification and prevent peeling. Twisting branches, twisting branches and taking branches: twist or slightly damage phloem and xylem to change the branching direction and promote the formation of flower buds.
(3) Pruning points in different periods: young tree period: from planting to first fruit. This period is dominated by plastic surgery, with light cutting and slow release. Fruitful period: a period when fruits are abundant. According to tree potential, seed setting rate and other factors. , try to get rid of vigorous long branches (above 80 cm), cut short new branches, cut short long branches (15-30 cm) and intermediate branches (5- 15 cm), and shrink and cut off perennial branches to prevent years.
