Street tree planting substrate, screening method thereof and street tree planting system

Abstract

The invention discloses a street tree planting substrate, a screening method thereof and a street tree planting system, and relates to the technical field of urban road landscaping. The street tree planting substrate comprises filled particles and formula soil, the filled particles comprise building bluestone particles, the diameter of the filled particles ranges from 1cm to 5cm, the formula soil is mixtures of loam and composts, specific planting substrates are provided for street trees, so that the street trees have growing environments matched with street tree species, the planting effect of urban street trees is improved, and economic benefits and environmental benefits of the urban street trees are improved. The screening method of the street tree planting substrate has important significances of guiding planting and managing modes of the urban street trees, improving the growth quality of the street trees and sufficiently playing greening functions of the street trees. According to the street tree planting system, healthy growth of the street trees can be effectively ensured, functions are continually played, and the comprehensive service functions of an urban overall greening ecological system are improved.

Description

technical field [0001] The invention relates to the technical field of urban road landscaping, in particular to a street tree planting substrate, a screening method for the street tree planting substrate and a street tree planting system. Background technique [0002] Urban street trees are an important part of urban plants and play a pivotal role in urban ecosystems. With the rapid development of the city, its land use structure has undergone major changes, from the previous natural landscape to concrete roads and a large number of artificial buildings. Urban soil is characterized by large temporal and spatial variability, numerous human-made additions, chaotic soil profile structure and developmental morphology, denatured soil physical structure, disturbed soil nutrient cycle and soil biological activities, and high pollution. These undesirable characteristics hinder the normal development of the root system of street trees in urban greening, and make them unable to perfo...
