Ecological restoration planting material for landfill closure and regreening method

Abstract

The invention belongs to the technical field of soil improvement and vegetation recovery, and particularly relates to an ecological restoration planting material for landfill closure and a regreeningmethod. The planting material is prepared from, by weight, 60%-80% of planting soil, 10%-20% of sandy soil, 3%-6% of organic fertilizer, 1.5%-2.5% of sludge, 1%-2% of a water-retaining agent, 1%-2% ofsawdust, 3%-6% of water and 0.5%-1.5% of compound fertilizer. The ecological restoration planting material for landfill closure improves soil for the complex growth environment after landfill closurein a targeted mode, growth of plants is better facilitated, and ecological regreening can be achieved as soon as possible; in addition, matching of the planting material is scientific, no pollution exists, the seedling survival rate is high, the regreening effect is good, and the adverse effect caused by the complex environment after landfill closure on growth of the plants can be effectively relieved; material taking for all components is convenient, waste such as the sawdust and the sludge is added into the planting material, waste reuse is achieved, and ecological environmental protectionis achieved; matching is easy, and the operability is achieved.

Description

technical field [0001] The invention belongs to the technical field of soil improvement and vegetation restoration, and in particular relates to an ecological restoration planting base and a regreening method for closed waste landfills. Background technique [0002] At present, sanitary landfill is the main treatment method for municipal solid waste in my country. If the land after closure is not planned and developed in time, it will waste land and deteriorate the environment. Ecological restoration of municipal solid waste landfill after closure will be beneficial The stability of the regional ecosystem, the healthy development of the city and the improvement of the living environment are extremely important. [0003] According to the relevant provisions of CJJ 112-2007 "Technical Regulations for Closure of Domestic Garbage Sanitary Landfills", the structure of the closure covering system from the surface of the garbage dump to the top surface should be: exhaust layer, anti...

AI Technical Summary

Problems solved by technology

[0005] Part of the domestic waste landfills are closed for vegetative vegetation layer to improve the soil by adding sand, adding peat soil, and applying organic fertilizers, etc., which can basically meet the normal growth of plants, but they are not targeted at the complex growth environment of plants after closure improving the soil
