Abstract

The utility model relates to an urban tree health management device in gardens and the forestry field, specifically speaking is an improve ecological tree pool of urban tree root system habitat, ecological tree pool includes the careless stone median, clay haydite and ecological saw-dust, according to the field situation of trees, select circular or square tree pool, clear away the soil of trees periphery external fixed range, enclose the careless stone median and put soil facade department, two-layer filler about filling in the careless stone median, the clay haydite is put into and is paved to the lower floor, the upper strata covers ecological saw-dust, keep level with the existing soil horizon after covering. The utility model discloses can utilize the clay haydite to absorb water, breathe freely, hold fertile effect, fill the tree pool, breathe for the root system and increase the permeability, improve the ability of permeating water and retaining water, improving soil, beautifying the view through covering ecological saw-dust, the improvement of the trees root system habitat by the soil layer thickening in the specially adapted city.

Description

Ecological tree pool for improving root system habitat of urban trees

Technical Field

The utility model relates to a city trees health management device in gardens and the forestry field, specifically speaking are ecological tree pool who improves city trees root system habitat.

Background

In cities, especially old urban areas, road elevation is often caused by road paving construction and other conditions. The raised road surface can force urban trees such as street trees and the like, and the soil layer is thickened on the basis of the original soil layer surface so as to match the landscape raised on the road surface. The thickening of the soil layer not only affects the permeability of the soil and is easy to accumulate water to hinder the respiration of the roots of the trees, but also causes root rot, nutrient deficiency, insect damage, scorched and dead trees and the like, and seriously harms the health of the trees. For example, the transplanting of trees in a thickened soil layer or in-situ transplanting consumes a large amount of financial resources and manpower, and the survival rate of large trees growing for many years cannot be guaranteed. This is an important problem to be solved in the in-situ state of urban trees.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems existing in the urban tree in-situ state, the utility model aims to provide an ecological tree pool for improving the root habitat of urban trees.

The purpose of the utility model is realized through the following technical scheme:

the utility model discloses a careless stone median, clay haydite and ecological saw-dust, wherein the peripheral soil of the week of trees is clear away, and the degree of depth of cleaing away soil is for the height between present soil aspect and the former soil aspect, the facade department of soil between present soil aspect and the former soil aspect is put in the careless stone median around, and this careless stone median inside packing has upper and lower two-layer filler, and the filler that is located the lower floor is the clay haydite of paving, the upper strata of clay haydite covers has ecological saw-dust, this ecological saw-dust cover after paving with present soil aspect keeps flat.

Wherein: the ecological tree pool is round or square.

The range of the soil removed from the periphery of the tree is 60-100 cm outside the circumference of the tree.

The clay ceramsite is 10-20 mm in diameter and spherical in shape.

The ecological wood chips are 3-5 cm of strand-like objects obtained by crushing withered and residual branches of trees by a machine.

The ecological wood chips are dyed in various colors.

The straw stone isolation belt is made of PE materials and has a barrier effect.

The utility model discloses an advantage does with positive effect:

the utility model discloses utilize the clay haydite to absorb water, ventilative, hold fertile effect, fill the tree pool in, for the root system breathing has increased the permeability, improve the ability of permeating water and retaining water, improving soil, beautifying the view through covering ecological saw-dust, the improvement of the trees root system habitat by the soil layer thickening in the specially adapted city.

Drawings

Fig. 1 is a top view of the structure of the present invention;

FIG. 2 is a schematic structural view of the present invention;

wherein: 1 is a grass-stone isolation belt, 2 is clay ceramsite, 3 is ecological wood chips, 4 is an original soil layer, 5 is an existing soil layer, and 6 is a tree.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the utility model comprises a grass-stone isolation belt 1, clay ceramsite 2 and ecological wood chips 3, wherein a round or square tree pool can be selected according to the field situation of trees; according to the size of the breast diameter of the tree, soil on the periphery of the circumference of the tree 6 is removed, the range of the soil on the periphery of the tree 6 to be removed is 60-100 cm outside the circumference of the tree 6, and the depth of the removed soil is the height between the existing soil layer 5 and the original soil layer 4; in this embodiment, the tree 6 is used as a central point, and the length of 60cm outside the circumference of the tree 6 is used as the radius range of the tree pool, so as to remove the soil within the range of 60cm outside the circumference of the tree 6. Enclosing and placing the grass-stone isolation belt 1 at the vertical surface of the soil between the existing soil layer 5 and the original soil layer 4, wherein an upper layer and a lower layer of fillers are filled in the grass-stone isolation belt 1, the fillers positioned at the lower layer are paved clay ceramsite 2, the upper layer of the clay ceramsite 2 is covered with ecological wood chips 3, and the ecological wood chips 3 are leveled with the existing soil layer 5 after being covered and paved.

The grass-stone isolation belt 1 is made of PE material, has good toughness, is used for dividing regions and plays a role in blocking; the width and the length of the grass-stone isolation belt 1 are determined according to the depth of the removed soil and the perimeter of the tree pool.

The clay ceramsite 2 of the embodiment has a diameter of 10-20 mm, a spherical shape, and strong water absorption, air permeability and fertilizer holding capacity.

The ecological wood chips 3 are 3-5 cm strips obtained by crushing withered and residual branches of trees by a machine, can be dyed into various colors, are used as colored organic coverings on gardens, and have the characteristics of water permeability, water retention, soil improvement, temperature regulation, weed inhibition, novelty, attractiveness and the like.
