Description
Technical field
The present invention relates to recovery of ecologic environment in a mine field, more particularly to a kind of metal mine discards the ecological recovery method on ground.
Background technology
China is a mineral resources big country, and the exploitation in a large amount of mines is entirely gone through along with the fast-developing of China's economy
Journey, and it is made that significant contribution, but at the same time for economic development, the recovery activity in mine is in itself and its " three wastes " pollution is also made
Into the very big destruction of the ecological environment on mine periphery.Abandoned Land of Mine mainly includes after concentrate screening remaining rock fragment and low
Refuse dump that the time-consuming heap that forms of taste ore accumulation, overburden Asia account for, the tailings ore deposit that tailings ore deposit is formed, spoil accumulation spoil
The types such as mountain.The original ecosystem of Abandoned Land of Mine is destroyed, and forms extreme habitat conditions, influences the colonization of plant,
The excessively high and extreme pH of middle heavy metal content in soil is the main limitation sex factor for influencing plant growth.Metal mine is due to discarded
Ground containing sulfur minerals matter is exposed in air, and oxidation reaction easily occurs, and meets the leaching that water just forms Extreme acid waste water, spent acidic
Water further leads to the precipitation of heavy metal in mineral, the pole acid soil environment rich in heavy metal is ultimately formed, if not to naked
Dew carries out revegetation discardedly, and soil environment will further be deteriorated, the acid waste water rich in heavy metal ion
Diffusion is caused into greater area of soil pollution.
In Abandoned Land of Mine ecological recovery, soil matrix improvement is firstly the need of solving the problems, such as to be also key problem.
Common soil improvement method has the methods of physically improved, chemical modifying, biological modification, wherein physically improved mainly covered with soil moved in improve the original
Based on lid, the method is quick, but needs a large amount of soil moved in improve the originals, limits its large-scale use, and biological modification refers mainly to microorganism
Improved method, for microbial process for controlling soil acidification, improving soil fertility has better effects, but cannot eliminate soil very well
The murder by poisoning of acidic materials and heavy metal, chemical amendments are still the mainstream selection of soil matrix improvement, have quick, cost
Low advantage in existing patented technology, or the use of soil improvement material is excessively complicated, is often not easy to purchase in practical applications
It buys, cost is excessively high, limits that it is promoted the use of or improved materials are excessively single, and such as single applies lime, it is impossible to effectively disappear
Except the murder by poisoning of high concentration heavy metal, so as to cause the difficulty of plant growth.
Invention content
In order to overcome the shortcomings of the prior art, the Extreme acid and height on discarded ground to be formed are exploited for metal mine
Concentration multi-metal Soil ecology restoration problem, the purpose of the present invention is to provide the ecological recoveries that a kind of metal mine discards ground
Method, it is intended to solve to carry out original position soil improvement and quick ecological restoration using Extreme acid and high concentration multi-metal soil
Problem.
The embodiment of the present invention is achieved in that a kind of metal mine discards ground ecological recovery method, includes the following steps：
(1) loose processing is carried out to place surface layer 5-10cm soil, and punch by 1m spacing with creeper, aperture 2-4cm,
Hole depth 20-40cm is differed；
(2) mixture is configured by mass fraction 5-15%, 55-65%, 25-35% in charcoal, quick lime, bentonite,
Usage amount is calculated according to the mixture of every square metre of area 0.6-1kg, 6-8 times of water is added to be modulated into slurries and is uniformly sprayed on place
Surface treats that it slowly permeates and dry 1-2 days；
(3) rake pine is carried out to place topsoil again, then mixes vegetable seeds, organic fertilizer, water-retaining agent, calcium magnesium phosphate
After conjunction plus water stirs evenly, and is sprayed on soil surface with special hydroseeding equipment, wherein vegetable seeds dosage is 3-5g/m2, plant
Seed for blechnoid, beggar-ticks, Formosan paulownia (Cortex seu Radix Paulowniae kawakamii) mixture, three's mass fraction ratio be 1：2：1, the usage amount of organic fertilizer is
0.5-0.8kg/m2, water-retaining agent usage amount is per square water 0.3-0.5kg, and calcium magnesium phosphate usage amount is 0.1-0.2kg/m2；
(4) it covers non-woven fabrics and carries out maintenance management after 1 month, plant mulberry tree seedling, plantation spacing is 2-3m.
Beneficial effects of the present invention：By the direct ameliorative measure of soil to Abandoned Land of Mine, a soil huge sum of money is effectively reduced
Influence of the murder by poisoning and extreme pH environments of category to plant growth is created and is suitble to ecological recovery initial stage required basic soil item
Part, then by broadcasting sowing with being adapted to the ore deposit herbaceous plant of soil environment, shrub seed, be then done step-by-step by planting mulberry tree
The ecological recovery on discarded ground and safety in production function；Since the present invention is that discarded original soil is directly improved, so there is no need to visitors
Soil, is greatly saved cost and flow, and the less destruction to land resource；The soil matrix improvement material used in the present invention
Material, formula is simple and effective, and purchase is convenient, convenient for promoting the use of；The plant used in the present invention is summarized from research and practice
And obtain, good structure of community and ecological duration can be formed, while mulberry tree can also breed silkworms and play added economic value.
