Embodiment

[0026] This example is the application of plants, animals and microorganisms in the restoration of steel slag hills in the Taizi River Basin of Benxi.

[0027] (1) Repair method

[0028] According to the different characteristics of different locations of the steel slag hills in the Taizi River Basin of Benxi, the ecological restoration area of ​​the steel slag hills is divided into the restoration area at the foot of the steel slag hills, including the gaps between the steel slag hills, where the terrain is relatively flat; the restoration area on the side of the steel slag hills, where the terrain is steep; The restoration area on the top of the steel slag mountain is flat but narrow in width.

[0029] For the restoration area at the foot of the steel slag mountain (area A)

[0030] 1. Inoculation of VA mycorrhizae

[0031] Select wild Xanthos sorbifolium with a tree age of 15 years, dig out the rhizosphere and fine roots 35cm below the surface to obtain VA mycorrhizal fun...

Abstract

The invention relates to a method for plant-animal-microorganism combined restoration of an abandoned steel rehabilitation hill, belonging to the technical field of ecological restoration. According to the invention, a steel rehabilitation hill is divided into a steel rehabilitation hill foot restoration zone, a steel rehabilitation hill versant restoration zone and a steel rehabilitation hill toprestoration zone, wherein each area adopts different animals, plants and microorganisms. For the steel rehabilitation hill foot restoration zone, the method of restoration via a combination of Xanthoceras sorbifolium Bunge, Haloxylon ammodendron and VA mycorrhizas is adopted; for the steel rehabilitation hill versant restoration zone, the method of restoration via a combination of creepers and earthworms is adopted; and for the steel rehabilitation hill top restoration zone, the method of restoration via a combination of torch trees and AM mycorrhizas is adopted. With the method, the landscape of the steel rehabilitation hill and the surrounding landscape are made beautified, and the quality of water around the steel rehabilitation hill is greatly improved.

Description

technical field [0001] The invention relates to a method for jointly repairing abandoned steel slag hills by using plants, animals and microorganisms, and belongs to the technical field of ecologically repairing abandoned steel slag hills. Background technique [0002] my country is now in the middle and late stage of industrialization development, the demand for steel is huge, and the steel industry has a large market space, which produces a large amount of scrap steel slag, and these scrap steel slags are generally piled up and placed, accumulating over time, and the steel slag piles up into mountains, thus forming Steel slag mountain. Scrap steel slag contains CaO, Pb, Cr, Zn and other heavy metal elements. If these oxides and heavy metal elements enter the water body, the pollutant content in the aquatic organisms will increase. If people eat these aquatic organisms, it is likely to produce corresponding poisoning phenomenon, even life-threatening; if the silty particles...
