Description

Planting process of lonely planted tree

Technical Field

The invention belongs to the field of landscaping, and particularly relates to a planting process of an isolated plant tree.

Background

The isolated planting trees are also called garden trees, exclusive ornamental trees or specimen trees, have stronger individuality and high ornamental value, are suitable for the tree species of isolated planting in gardens, and remarkably reflect the individual beauty of the single plants of the trees in landscaping. The method is commonly used at important nodes of garden landscapes such as courtyards, squares, lawns, rockeries, nearby water surfaces, garden path intersections, building sides and bridge heads. The method for constructing the garden landscape by the bouquet trees requires beautiful tree shapes, unique postures or unique colors of flowers and leaves, and has high requirements on the ornamental value of the garden trees.

In addition, for the plant landscaping space, a certain open land section is required around the lonely planted tree, and generally, no other scenery exists within the range of 4-10 times of the height of the tree or no tall object can obstruct the sight. Functionally, the isolated plants can be used as a main scene of a local garden space to show the unique individual beauty of the trees and also play a role of shading, so large and medium trees are often selected.

Therefore, the lonely-planted trees firstly have a good growing environment to ensure the healthy growth of the lonely-planted trees, and the branches, the leaves and the flowers and fruits present pleasant ornamental states; but also maintains the long-term stable landscape effect and the corresponding organism amount. This places severe demands on soil quality and cultivation techniques. Then, it is more difficult to build landscape tree independent landscape in saline soil area with salt content higher than 0.6%.
