How to carry out plastic pruning according to the growth characteristics of branches and buds of garden plants

First of all, we must ensure the tree shape

No matter how good it looks.

Both should be removed, and the other should pay attention to the number of branches left.

The branches of ornamental flowers and fruit trees can produce more short and medium branches, which are easy to form.

2. Medium and short cutting: cutting off the whole buds in the middle or upper part of the branches (the length of the cutting band is 1/3— 1/2), which is mainly used for some.

3. Rough and short shears: cut off 2/3-3/4 of the total length of branches. This pruning method has a great stimulating effect and is mainly used for weak trees.

The old and weak branches are rejuvenated.

4. Extremely heavy and short cutting: leave 1-2 dead buds at the base of the tree belt, and cut off all the others. In the garden

This method is often used.

5. Retraction: It means cutting off some perennial branches. Because trees have been growing for many years,

The top is far away, and the base is easy to show its legs, in order to be lower.

Apical dominance

Position, promote the regeneration and rejuvenation of the base of perennial branches, and often use retraction pruning method.

Pay attention to the following questions when pruning trees:

1. The cut of the pruned branches should be smooth and form a 45-degree angle with the cut buds.

slanting

Flat, the lowest part of the slope, and

Wounded surface

Small, easy to heal, buds grow fast after germination. Cut off the openings of sparse branches at the branch points and connect them with the stems, leaving no residual piles. Grow thick

Sparse branches are flush with the ground. The direction and quality of bud cutting were determined.

Growth direction and growth direction of branches. Choosing the direction of bud cutting should be from

Crown of a tree

Considering the distribution of internal branches and the expected growth of new branches, it is necessary to

be away from home

When expanding the crown, the cut buds should be left outside the branches. If you want to fill the gap in the inner room, the buds should be cut inward. For branches that grow too vigorously, weak buds should be used as cutting buds, and when supporting weak branches, full strong buds should be selected.

2. On a larger scale

3. Sawing larger branches, resulting in

4. The pruning period of deciduous trees and evergreen trees should be different.

Deciduous trees stopped growing, so they were pruned.

Activity, metabolism, so the nutrients in the leaves are not completely used for storage. When the branches and leaves are cut off, the nutrients are lost, which affects the growth of trees. The pruning period of evergreen trees in winter has generally passed.

5. When pruning, tools should be kept sharp, and trees should be placed on machinery and ladders. Before use, check whether all components are flexible and loose to prevent accidents.

On the tree

Fasten the safety rope when operating. When working near high-voltage lines, pay special attention to safety to avoid electric shock, and ask the power supply department to cooperate if necessary.

Trees by the roadside

When pruning, there will be someone to maintain the site to prevent sawing.
