What are trees and how to improve the Survival rate of trees

In order to make trees look good, we should not only make more efforts in breeding, but also understand the knowledge of trees, learn to allocate trees reasonably and skillfully integrate trees and shrubs, which are all worth studying.

How many kinds of trees are there?

There are many kinds of trees, including more than 2000 according to incomplete statistics. According to whether it is evergreen or not, trees can be divided into deciduous trees and evergreen trees. According to its height, we can divide it into Weiqiao of more than 31 meters, Big Joe of 21 to 30 meters, Zhongqiao of 11 to 20 meters and Xiao Qiao of 6 to 10 meters. Can also be divided into different families, there are Lauraceae, Platanaceae, Salicaceae, Cypress and so on hundreds of families and genera, hundreds of families under each family and dozens of species of trees. So the Arbor family is a very large family. There are trees in almost all families and genera of Monocotyledon except that there are no trees.

II. Optimal allocation of trees

1. The same tree configuration of the same height: the formation of equal-height canopy lines, straight and monotonous, simple and spectacular, but also can show the morphological beauty of a particular tree species. For example, cylindrical trees do street tree planting and forest belt planting.

two。 The configuration of trees with different crown shapes: the canopy lines composed of trees of different heights determine the vision of visitors and affect their sense of space.

3. Isolated tree configuration: sometimes in the forest canopy line undulating bushes, highlight an extra-tall isolated tree, play the role of a sign and tour guide.

4. Repetitive tree configuration: repeated image will expand people's viewing field of vision, can arouse people's visual attention, and is easy to form as a visual center or ornamental focus.

5. Arbor configuration that gives rhythm: the order of arrangement can vary from small to large, from high to low, and from dense to sparse.

6. Reflect the configuration of contrast and harmony: in the configuration of trees, take the form of gradual change, or increase its repetitive and similar modeling image, so that the whole work to increase consistent factors, to achieve a more perfect effect.

Third, planting methods to improve the survival rate of trees.

1. Spray the solution. First, according to the need to prepare the corresponding concentration of spraying plants, the liquid droplets are required to be small and uniform, with the wetness of the spraying site as the degree. In order to make the agent easy to adhere to the plant surface, a little emulsifier, such as washing powder, neutral soap, or surfactant and other auxiliaries can be added to the agent to increase the adhesion of the agent.

two。 Immersion. It is often used to promote rooting of cuttings, seed treatment, fruit ripening, storage and fresh-keeping, etc.

3. Smear method. The high-altitude strip incision smearing method can be used for the culture of valuable and difficult-to-root flowers. The method is to ring-cut the branches to expose the phloem, smear the lanolin containing auxin on the cut, keep it moist with moss, and wrap it with a thin film to prevent water evaporation.

4. Soil irrigation. Plant growth regulators were mixed into aqueous solution and poured directly into the soil or mixed with fertilizers to make the roots fully absorbed.

Arbor is a kind of tree that must be used in landscaping design, generally speaking, trees are not difficult to raise, so if there are suitable conditions at home, you can also carry out domestic trees, there are many kinds of trees to choose from.
