Planting technique pruning of Myrica rubra

Pruning time: pruning twigs from March to April in spring, strong branches from June to July in summer, vegetative branches and slightly in autumn in November. Pruning methods: there are mainly methods of wiping buds, coring, cutting, thinning, retraction, drawing branches, supporting branches and ring peeling, etc. different pruning methods are adopted for different branches according to different stages, which can quickly form the crown, restore the tree potential, improve the fruit setting rate and so on.

Pruning time

The main results are as follows: 1. The pruning time in spring is from March to April, at this stage, the twigs are mainly pruned, some withered branches and dense branches can be trimmed off, and the branches that bear too much fruit can be truncated.

2. The summer pruning time is from June to July, when the big branches and strong branches that disturb the tree shape can be trimmed off.

3. The time of autumn pruning is November, at this stage, some excessively strong vegetative branches and autumn are trimmed off.

2. Pruning method

The main results are as follows: 1. The pruning methods of bayberry include sprouting, coring, cutting, thinning, retraction, branch pulling, branch support, ring peeling and so on, which summarize all the steps of pruning bayberry.

2. Sprouting and heart-picking: mainly for young trees, it is beneficial to promote more branches of plants, form crowns quickly, and lay a good foundation for increasing production in the future, while others are for fruiting trees.

3. Truncation: in order to promote the renewal and rejuvenation of branches, restore the tree potential, so that declining trees and large lateral branches can be renewed and rejuvenated.

4. Thinning: in order to improve the permeability of the crown, it is more helpful to blossom and bear fruit.

5. Retraction: in order to speed up the growth of mother branches, so that declining trees and large lateral branches can be renewed and rejuvenated.

6. Pull branches and brace branches: in order to make the crown expand outward, to prevent the inner chamber branch from becoming bald.

7. Girdling: it is beneficial to promote flower bud differentiation and improve fruit setting rate.

Matters needing attention in pruning young trees

The main results are as follows: 1. in general, young trees set their stem at 30-50. After sprouting a little in spring, 3-5 strong shoots can be selected to cultivate them into main branches, and the rest are lateral branches.

2. When the main branch grows to a certain extent, one can be selected as the secondary main branch according to the trunk 50cm, while the second secondary main branch needs to be on the other side of the first secondary main branch, and the lateral branches need to be cultivated to form a crown quickly, which can lay a foundation for early fruit.

IV. Pruning methods during the growing period

Pruning in growing period can be divided into two decisions: spring pruning and autumn pruning.

Generally, spring pruning is from April to May, after pruning, it is beneficial to promote root germination and growth, so that the time of spring is longer than that of flowering and fruiting, so as not to compete for nutrients between new sprouts and flowering and fruiting, so it can increase the rate of fruit setting.

3. Generally, autumn pruning is from October to November, which is helpful to promote flower bud differentiation, and the overgrown branches germinated in the later stage should be pruned in time to avoid nutrient loss.
