[0002] When designing garden landscapes, it is necessary to plant trees and shrubs in local areas for greening and beautification. When the trees and shrubs are planted in shallow soil layers such as on the top plate of the basement or on the roof garden where the soil covering for planting is relatively shallow, the soil covering load is limited, making it difficult to meet the requirements for the stable planting of trees and shrubs and for wind prevention and anti - lodging, which is not conducive to the stable growth of trees and shrubs and also poses certain potential safety hazards to the surrounding people's activities.

[0003] The existing general support for trees and shrubs is usually above the ground. Bamboo, wood or steel pipe materials are used to form a triangular or quadrilateral support within the range of one meter from the ground to the tree height, and ordinary ropes or steel pipe connecting members are used for connection. This kind of support generally has a total height of 1 - 1.3 meters and is used above the ground, which will affect the overall aesthetic effect of the landscape.
