Abstract

The invention discloses a soilless planting base material for vegetation recovery of a metal ore waste rock field, and a vegetation recovery construction method thereof. The soilless planting base material comprises HDS bottom mud, rice hulls, fermented sludge, an organic polymerization crosslinking agent and a microbial agent. The vegetation recovery construction method comprises the following steps: pretreating the metal ore waste rock field, preparing a thick-slurry acidic improving material from an acidic improving matrix and water, spraying the thick-slurry acidic improving material to the surface of the to-be-recovered metal ore waste rock field, curing, uniformly mixing the soilless planting base material with plant seeds, and blowing and sowing the obtained mixture to the surface of the metal ore waste rock field containing the acidic improving layer. According to the soilless planting base material, recycling of solid waste and vegetation recovery without alien soil in a metalore waste rock field can be achieved, and the content of organic nitrogen, phosphorus, potassium and organic matters in soil is adjusted; and the vegetation recovery construction method is good in environmental benefit and social benefit, simple in process, good in effect and suitable for large-area application, and the problems that a large amount of dust exists in existing construction and is harmful to health of workers can be avoided.

Description

technical field

[0001] The invention belongs to the technical field of vegetation restoration, and relates to a vegetation restoration of a metal ore waste rock field, in particular to a soilless planting base material for vegetation restoration of a metal ore waste rock field and a construction method for vegetation restoration thereof. Background technique

[0002] Acidification of mining waste is a relatively common phenomenon in the prior art. Metal mines have a large proportion of sulfide in minerals, accounting for about 75% of the total amount of various minerals. Due to the extremely low grade and high mineral stripping ratio, a large amount of solid waste is generated; 1 ton of ore produces an average of 1.25 tons of waste rock. In recent years, about 130-140 million tons of waste rock have to be discharged per year, and billions of tons have been accumulated.

[0003] The waste rocks are piled in the open air, and under the catalysis of microorganisms such as Thio...
