Plastic pruning is an important link in the maintenance and management of garden trees. Its main functions are as follows:
1, beautify the tree
Garden trees will be affected by environmental and human factors in the growth process, such as overhead lines, people and vehicles, so it is necessary to adjust the tree shape and combine the role of garden trees in beautifying the city in operation. Therefore, trees can create a combination of artificial and natural beauty on the basis of natural beauty by shaping and pruning.
2. Coordination ratio
In the garden attractions, garden trees sometimes play a role of foil, not too high to foil some scenic spots and buildings, so it is necessary to adjust the ratio of trees to the environment in time through modeling and pruning to achieve good results. For the trees themselves, pruning can coordinate the proportion of crown height and ensure their ornamental needs.
3. Adjust the tree potential
Garden trees grow differently due to different environments, and the strength of trees can be adjusted by shaping and pruning. Through pruning, we can get rid of the bad and preserve the good, promote local growth and weaken the redundant parts, while excessive pruning will weaken the whole, which is the so-called "double effect of pruning". Whether it is "promotion" or "inhibition", it varies with tree species, pruning methods, periods, tree ages and bud cutting conditions.
3. Improve light transmission conditions and reduce pests and diseases.
Some garden trees, such as natural growth or improper pruning, often have dense branches, closed crowns, weak growth potential of internal branches and high humidity of crowns, which creates a breeding environment for pests and diseases. Proper shaping and pruning can ensure the ventilation and light transmission of the crown and reduce the occurrence of pests and diseases.
4. Promote flowering and fruiting
Correct pruning can concentrate nutrients on the remaining branches, promote most short branches and auxiliary branches to become flower branches, and form more flower buds, thus achieving the purpose of dense flowers and increasing fruit yield.
