Problems solved by technology

However, at present, the flora of urban green space often pays attention to the function of viewing and recreation, ignoring the role of flora that can maintain the water balance of flora by increasing rainwater absorption and improving the drought resistance of flora, which not only reduces rain and flood disasters, but also saves water resources and conservation management costs

Embodiment 1

[0034] This embodiment 1 is implemented under the following conditions of implementation and technical requirements:

[0035] 1. Construct a 20m*20m water-saving garden plant community in Minhang, Shanghai. Including the underground part of the rainwater storage area and the above-ground part of the planting area.

[0036] 2. Each side of a 20m*20m square is divided into three equal parts, and a well-shaped groove is set. The depth of each groove in the well-shaped groove is 1.5m, and the width is 2.0m. The composition of crushed stones is: crushed stones with an average diameter of 20 mm: the volume ratio of crushed stones with an average diameter of 40 mm = 6: 4, and the planting soil is backfilled on it, and the composition of the planting soil is: medium loam: peat soil volume ratio = 7: 3 .

[0037] 3. The planting area is a multi-layer mixed plant community, the upper layer: large trees, the height is > 5 meters, the canopy density is 65%, and the number ratio of everg...

Embodiment 2

[0043] This embodiment 2 is implemented under the following conditions of implementation and technical requirements:

[0044] 1. Construct a 20m*20m water-saving garden plant community in Baoshan District, Shanghai. Including the underground part of the rainwater storage area and the above-ground part of the planting area.

[0045] 2. Each side of a 20m*20m square is divided into three equal parts, and a well-shaped groove is set. The depth of each groove in the well-shaped groove is 1.2m, and the width is 1.8m. The crushed stone composition is: crushed stone with an average diameter of 20mm: the volume ratio of crushed stone with an average diameter of 30mm = 6: 4, and the plant planting soil is backfilled on it, and the plant planting soil is composed of: medium loam: peat soil volume ratio = 8: 2 .

[0046] 3. The planting area is a multi-layer mixed plant community, the upper layer: large trees, the height is > 5 meters, the canopy density is 68%, and the number ratio of...

Embodiment 3

[0052] This embodiment 3 is implemented under the following conditions of implementation and technical requirements:

[0053] 1. Construct a 20m*20m water-saving garden plant community in Pudong, Shanghai. Including the underground part of the rainwater storage area and the above-ground part of the planting area.

[0054] 2. Each side of a 20m*20m square is divided into three equal parts, and a well-shaped groove is set. The depth of each groove in the well-shaped groove is 1.5m, and the width is 1.8m. The composition of crushed stones is: crushed stones with an average diameter of 20 mm: the volume ratio of crushed stones with an average diameter of 35 mm = 6: 4, and the plant planting soil is backfilled on it, and the plant planting soil is composed of: medium loam: peat soil volume ratio = 7: 3 .

[0055] 3. The planting area is a multi-layer mixed plant community, the upper layer: large trees, the height is > 5 meters, the canopy density is 70%, and the ratio of evergree...

Abstract

The invention relates to a method for constructing a water saving type landscape plant community, comprising the following steps of: firstly, leveling a landform of a square construction area of 20m*20m; then, arranging a #-shaped groove at a trisection position of each side of the area, horizontally laying a gravel layer at the bottom of the #-shaped groove, and backfilling plant growing soil on the gravel layer; complexly planting a mixed plant community on the plant growing soil; and finally, covering saw dust in the thickness of 10cm at a base part of trees and shrubs. The method for constructing the water saving type landscape plant community can meet the requirement on rainwater storage of the water saving type landscape plant community and homeostasis in a water community so as to achieve the purposes of reducing irrigation and saving water resources.

Description

technical field [0001] The invention relates to a method in the technical field of landscaping, in particular to a method for constructing a water-saving garden plant community. Background technique [0002] The rapid development of the global economy and the expansion of population have led to the shortage of global water resources, and the problem of water resources in my country is particularly prominent. There are many reasons for the shortage of water resources, and unreasonable construction methods in the process of urbanization are one of the reasons for the shortage of water resources. For example, in the city, a large amount of hard ground, when it rains, the rainwater fails to replenish the groundwater and quickly loses, and a large amount of rainwater flows into the urban rainwater pipes, which brings great pressure to the urban drainage. In the dry season, the lack of groundwater leads to a large amount of supplementary irrigation for urban green spaces, which w...
