1, pruning at the first fruit stage.

Mainly to regulate the relationship between growth and fruit. Continue to cultivate extension branches and crown expansion on backbone branches at all levels, and rationally allocate vegetative branches and fruiting branches. Control excessive growth of branches, retract weak branches, remove strong side branches, leave weak side branches, relieve tree potential, promote flower bud formation and maintain appropriate results.

2. Prune when the fruit is full.

Cut off strong and upright branches at the upper part of the crown to keep the crown open and indoor light sufficient. Sparse and dense branches, shrinking weak branches; Shorten some fruit branches to promote the preparation of branches, adjust the balance between growth and fruiting, and prevent the fruits from bearing in big and small years; Close the crown and remove the long branches. The hollow crown inside will shorten the long branches, promote branching and fill the gap.

3. Prune the fruiting branches.

Myrica rubra can adjust the balance of flowering, fruiting and vegetative growth by pruning, which can effectively alleviate the phenomenon of fruiting in big and small years. In the year when flower buds are well differentiated and there are many flowers, the pruning of fruiting branches is mainly short to reduce the flowering amount in the current year and promote the growth of fruiting preparation branches in the next year; In years with few flowers, pruning of fruiting branches should be based on thinning, while pruning of fruiting branches is not suitable for trees with few branches and poor flower bud differentiation.

Prune the big branches of fruit trees without shaping, and saw off the upper upright branches, the cross branches of two trees, the lower mopping branches, the dense branches in the crown and the overlapping branches.

For multiple branchlets from one branch, the upper part of the crown should be stripped of strong branches, and the lower part of the crown should be stripped of weak branches and strong branches. For the peripheral crowded branches, mainly prune the branchlets, prune the overgrown branches, dead branches, pests and diseases, weak branches, prune the dense branches and upright branches, so as to achieve one branch at a time, and keep the flowering branches and late autumn branches open, so as to promote the aging and sturdiness of branches.

Pruning of fruit trees with weak growth potential should be carried out from late February to early March in spring, which is vulnerable to freezing injury too early and affects flowering and topping too late. When pruning, pay attention to adjust the structure of fruit trees in time, adjust the pruning amount according to the amount of flowers, adopt the method of thinning mainly, cut short appropriately, sparse too many dense branches, erect branches and short-cut weak and long fruiting branches, and update the fruiting branches group.

Through shaping and pruning, the open crown is dwarfed, the tree body is ventilated and transparent, and the three-dimensional effect is achieved. The crown height is controlled within 4 m. Through shaping and pruning, the upper part will not stand upright, the lower part will not mop the floor, the surroundings will not be crowded, the middle will not overlap, the inner room will not be bald, and the garden will not be closed.
