Plastic pruning is a very important technical measure in the maintenance and management of Shanghai garden plants
Plastic pruning is a very important technical measure in the maintenance and management of garden plants in Shanghai. In the garden, plastic pruning is widely used in the cultivation of trees, flowers and plants, as well as the artistic modeling and maintenance of bonsai, which plays a very important role in improving the greening effect and ornamental value. Shaping is the artificial means of the tree body to form a certain form of shape and posture. Pruning is to delete or shorten a certain organ of a plant to achieve the cultivation of garden plants. In addition to pruning, pruning techniques also include topping, twisting, pruning, pressing vines, braces, scaffolds, removing buds, thinning flowers, thinning flowers, Picking leaves, bunching leaves, ring peeling, cuts, peeling, etc.
The purpose and role of plastic trimming of garden plants
Shanghai garden green space conservation is a very important maintenance management technique for correct plastic trimming of garden plants. It can regulate the growth and development of plants, create and maintain reasonable plant forms, and form a garden landscape with certain characteristics.
1) The purpose of plastic trimming of garden plants
① Promote and inhibit the growth and development of garden plants through plastic trimming, control the size of their plant bodies, and create a certain shape. In order to exert its ornamental value and economic benefits,
② Adjust the relationship between the individual and group of cultivated garden plants to form a good structure.
③ It can adjust the balanced relationship between individual parts of garden plants. It can be summarized as the following 4 aspects:
a. Adjust the relationship between the ground and the ground. The above-ground branches of the garden plants and the roots of the ground are mutually restricted and dependent on each other. The two maintain a relative dynamic relationship. Pruning can purposefully adjust the relationship between the two to establish New balance.
In the greening of urban streets, due to the above-ground and underground cables and pipes, it is usually necessary to apply pruning and shaping measures to solve the spear between them and plants.
b Regulate the balance of vegetative and reproductive organs. In garden plants that observe flowers and fruits, spears that grow, bloom, and bear fruit always exist. They are woody plants. Improper treatment not only affects the current year, but also affects the next year and even the next few years. Through reasonable plastic pruning, a sufficient number of high-quality vegetative organs are ensured, which is the basis for plant growth and development; the plant produces a certain number of flowers and fruits. It is compatible with vegetative organs; part of the shoots grow, and some shoots flower and bear fruit. Years alternate so that the two grow in balance.
Plastic pruning can regulate nutrient and water transport. Balance tree potential can change the relationship between vegetative and reproductive growth, and promote flowering and fruiting. In flower cultivation, multiple toppings are often used to encourage more marigold branches and increase the number of flowering.
C. Regulate tree vigor and promote the regeneration and regeneration of old trees. For trees with strong growth and fewer flower buds. The pruning group can promote local growth, but as a part of the branches and leaves are cut off, the reduced assimilation will generally inhibit the whole tree, reducing the total growth of the whole tree, but for adults with many flower buds Trees, because part of the flower buds are cut off during pruning, have the effect of renewal and rejuvenation, but they can increase the total growth than unpruned. Promote the growth of the whole tree.
Strong pruning of aging trees, cutting or shortening all the side branches can stimulate the hidden buds to grow new branches. Some of them can be replaced with original cultivation branches with promising futures to form new canopies. It generally grows faster than the new seedlings planted, because it has a developed root system, and provides sufficient water and nutrients for the renewed tree.
2) The role of garden plant pruning
① It can promote local garden plants. After a part of the branch is cut, the growth potential of the cut branch can be enhanced. This is because the number of shoots is reduced after pruning. The shoots left by the concentrated supply of nutrients grow. At the same time pruning improved the light and ventilation conditions of the canopy. The photosynthesis efficiency was improved, and the nutritional level of local branches and buds was improved, thereby enhancing the local growth potential. Short cuts under general cuts. 3. The third bud grows gradually, and thinning only enhances the growth of the branches under the cut.
② It has inhibitory effect on the whole plant. Partial shoots are reduced due to pruning. The canopy is relatively small, the leaf volume and leaf area are relatively reduced, and the total amount of carbohydrates produced by photosynthesis is reduced. Therefore, pruning will reduce the total nutrient level of the tree and reduce the total growth. . Shanghai Plant Leasing, Shanghai Garden Greening Conservation http://gxxfzn.com/
