Urban street tree soil improving medium and application method thereof

Abstract

The invention discloses an urban street tree soil improving medium for promoting growth of urban garden street trees and an application method thereof in the technical field of soil improvement. The medium comprises the following components in percentage by weight: 35 to 45 percent of natural zeolite and 55 to 65 percent of turfy soil, wherein the natural zeolite is clinoptilolite, and the grain diameter ranges from 0.4 to 0.8 centimeter; and the pH value of the turfy soil is 5.0 to 5.9, the ventilation gap is between 27 and 29 percent, and the water-holding capacity is 52 percent. The medium can effectively improve the ventilation condition, pH value, nutrient condition and the like of the street tree soil in the urban gardens, and has good promoting effect on the growth of plants.

Description

technical field [0001] The invention relates to a medium in the technical field of soil improvement and its application, in particular to an urban street tree soil improvement medium for promoting the growth of street trees in urban gardens and an application method thereof. Background technique [0002] With the acceleration of urbanization and industrialization of human society, the rapid increase of urban population has brought a series of increasingly serious environmental and ecological problems. As an important part of the urban landscaping system, the soil habitat of street trees is affected by the rapid development of urbanization, and poor site conditions have become an important factor restricting the growth of new street trees. At present, the ecological problems in the soil of street trees are mainly manifested in the following aspects. First, in the process of urbanization, a large amount of original topsoil has been continuously destroyed. Most of the soil mat...

Problems solved by technology

First, in the process of urbanization, a large amount of original topsoil has been continuously destroyed. Most of the soil matrix for street tree planting is artificial backfill, which contains a large amount of soil intrusions, such as gravel, lime, asphalt, construction waste, etc. One of the reasons for soil barrenness and alkalinization, which is not conducive to soil microbial activities and the occurrence and growth of new plant roots

Second, the hard covering on both sides of the road, coupled with human trampling, makes the soil compacted and compacted, resulting in increased soil bulk density, decreased soil porosity, increased CO2 concentration in the soil, decreased O2 concentration, and poor air permeability, drainage and durability. reduced water capacity

Third, the soil of street trees is poor, the nutrient content is not high, and there is salinization

However, these are mainly aimed at farmland soil, and the formula has many components, and the production process is relatively complicated.
