Planting method for expanding root system growth space of street trees and supporting device

Abstract

The invention discloses a planting method for expanding the root system growth space of street trees and a supporting device. The planting method for expanding the root system growth space of the street trees is included, and the planting method comprises the steps of digging planting holes, placing supporting frames, laying planting layers, arranging a root controller, laying floor tiles and hoisting the street trees. The planting method is simple, all that is needed is to place the supporting frames around the planting holes and at the plant spacing positions between the tree plants of the street trees, widened holes are formed by utilizing the spacing between the supporting frames, the root system growth space is expanded through the widened holes, and therefore, the problem that the root systems damage the floor tiles on the sidewalk ground can be solved; and besides, the widened holes are filled with the planting layers, the root systems of the street trees can conveniently penetrate through and transversely grow in the expanded growth space, the filled planting layers are high in hydrophobicity, and drainage in rainy seasons is facilitated.

Description

Technical field [0001] The present invention relates to the field of planting trees of municipal road sideways, and more particularly to planting methods and supporting devices for expanding the growth space of the channel tree roots. Background technique [0002] The sidewalk tree is spectrous to shade the vehicle and pedestrians and constitute street views. [0003] At present, the sidewalk tree is the supporting facility of the road, and it is important to improve the regional ecological environment, eliminate noise, purify the air, so it is very important to plant the road trees. [0004] In general, the street tree is planted through the azure, but the existing sidewalk tree is planted, there are some problems, such as: [0005] (1) The width of the sidewalk is limited in some places, causing the root growth space of the channel tree in the width direction, resulting in a shallow root, the root is not strong, the roots are not strong, the trees are long; [0006] (2) The til...

AI Technical Summary

Problems solved by technology

[0005] (1) The width of the sidewalk is limited in some places, resulting in the limitation of the root growth space of the sidewalk trees in the width direction, resulting in shallow roots, not deep into the soil, weak roots, and poor growth of trees;

[0006] (2) Floor tiles need to be laid on the sidewalk, so it is often necessary to lay floor tiles around the tree pond and on the sidewalk. Before laying the floor tiles, the soil under the floor tiles should be compacted, and then a 200mm gravel layer, 150mm plain concrete, and 20mm cement should be laid Mortar, the material composition of these paving structures is not conducive to the growth of the root system, coupled with the limited space, the soil and space are trapped in the narrow tree hole, the surrounding environment is airtight and non-hydrophobic, it is difficult for the root system to grow downward, which makes the root system It grows horizontally towards the pavement surface, causing the pavement surface to arch, and the road surface is uneven, which affects pedestrians walking

[0007] At present, in order to solve the phenomenon that the root system grows to the surface and damages the pavement of the sidewalk and the square, the method of cutting down the tree root and repairing the tree pond is often used at present. This method has hidden dangers to the safety of the tree. Because some root systems After being cut down, the root-to-shoot ratio is out of proportion, and there are hidden dangers in the stability and safety of the tree. Once it encounters extreme weather such as typhoon and stormy weather, it will be uprooted and fall to the ground, affecting traffic and pedestrian safety.
