A kind of street tree planting method and tree hole structure

Abstract

The invention provides a method for planting street trees, comprising the following steps: a. Excavating tree holes at the place where street trees are to be planted; The volume ratio to the bluestone grains is 2:8; c. Arrange the planting device on the upper part of the bottom layer and spread the mixture of formula soil and bluestone grains to form the middle layer, and reserve the planting in the middle layer for planting street trees therein pit, wherein the planting device is located in the middle layer, the volume ratio of formula soil and bluestone particles is 5:5; d, the street tree to be planted is planted in the planting pit and is 5:5 with soil and bluestone The mixture of grains is filled; e, the upper part of the middle layer is covered with bluestone grains to form the upper layer. The invention also provides a tree hole structure suitable for the above planting method, which is beneficial to the respiration of the root system and the absorption of water and fertilizer, and can provide a matching growth environment for the street tree.

Description

technical field [0001] The invention relates to the field of street tree planting, in particular to a street tree planting method and a tree hole structure. Background technique [0002] Urban street trees are an important part of urban plants and play a pivotal role in urban ecosystems. As the medium for plant growth and the supplier of nutrients, the excellent characteristics of soil are the key factors for the good growth of street trees. In the prior art, street trees usually use a mixture of street soil and compost when they are planted. However, the inventors of the present application have found that due to the rolling of pedestrians or vehicles, the soil around the roots of street trees will be over-compacted, resulting in a decrease in soil porosity, an increase in bulk density, and a decrease in soil air permeability and water permeability. small, the penetration resistance of street tree roots increases; excessive soil compaction also reduces the contact area be...

AI Technical Summary

Problems solved by technology

[0004] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a street tree planting method and tree hole structure, which is used to solve the problem of street tree root growth and elongation speed caused by the small porosity and poor water permeability and air permeability of the existing tree hole structure. slowing down, changes in root morphology, reduction in aboveground biomass of plants, shortening of leaf length, closure of leaf stomata, inhibition of photosynthesis, etc.
