Description

A slope greening structure

technical field

The utility model relates to the field of greening, in particular to a side slope green covering structure.

Background technique

Topsoil remediation in dumps is a more scientific, economical, and commonly used greening method. However, after the slope is covered with soil, the topsoil and seeds tend to slide down the slope under artificial disturbance during artificial seeding. In addition, when it rains, due to the existence of water erosion , it is easy to wash the topsoil and seeds down the slope, which makes the slope greening of the dump site uneven. There are many seeds and thick topsoil accumulation on the bottom slope, which makes the coverage degree of the greening on the bottom slope large; the topsoil on the slope is loose and It is relatively barren, with fewer seeds, and more alopecia areata after greening.
