Abstract
The invention discloses a tailing pond soil conditioner and an application method thereof. By weight part, the tailing pond soil conditioner comprises: 30-40 parts of slow release fertilizer, 20-30 parts of turfy soil, 20-30 parts of medical stone, 15-20 parts of kieselguhr and 5-10 parts of water-retaining agents. The tailing pond soil conditioner and the application method thereof solve the problems that reclamation rate of tailing ponds is low due to the fact that the reclamation rate of the tailing ponds is limited by factors of poor structures, nutrient loss, heavy metal toxicity and the like of matrixes, not only solve secondary damage caused by a soil dressing method, but also improve utilization rate of fertilizer, and simultaneously achieve fixing effect for heavy metal in tailing pond soil, reduce toxicity of the matrixes, improve emergence rate of seeds, reduce harm to plant growth, and effectively reduce pollution of tailings to surroundings.
Description
Technical field
The invention belongs to Tailings Dam soil improvement field is and in particular to a kind of Tailings Dam soil conditioner and its application side
Method.
Background technology
With expanding economy, mineral products demand is increased substantially, the exploitation scale of mine resources increases, therefore therewith
The Tailings Dam quantity of output is continuously increased.Exposed tailings rainy season easily causes subsides and comes down, and strong wind season then causes dust
Fly upward, particularly the mine tailing containing heavy metal can cause severe contamination to the water body of periphery, soil, animals and plants etc., thus affecting
Health.The reclaiming of Tailings Dam can be recovered Diggings soil and be used function, protects farmland, Revegetation of Eco-environment, in mine life
State environmental improvement aspect plays an important role.Because Tailings Dam soil grades and porosity status are poor, soil is extremely barren, with much money
Belong to germination and the growth that the extreme habitat conditions such as toxicity affect plant, thus the difficulty of revegetation is larger.
At present, reclaiming of Tailings Dam is mainly quickly increase soil fertility by soil moved in improve the original and applying fertilizer.Though heavy metal pollution of soil
So convenient and swift, but by fetching earth source and cost of transportation is limited, and easily cause the secondary destruction such as soil erosion after fetching earth.Apply
Fertilizer law, due to Tailings Dam soil water-reataining fertilizer-keeping energy difference, can only improve soil fertility for the moment, and fertilizer nutrient runs off seriously, and
And the toxic action of the heavy metal on plants in tailings leads to the rate of reclaiming relatively low.
Content of the invention
The present invention is directed to the extreme habitat conditions of Tailings Dam, there is provided one kind has retain water and nutrients effect, once adds fertilizer
Persistently, while improving Tailings Dam soil matrix, heavy metal has fixation to effect, beneficial to plant growing, reduces to surrounding enviroment
Impact, the utilization rate of fertilizer and the Tailings Dam soil conditioner of percentage of seedgermination can be improved.
Another object of the present invention is to the above-mentioned Tailings Dam soil improvement that offer is a kind of simply, efficient, planting effect is good
The application process of agent.
Technical program of the present invention lies in providing a kind of Tailings Dam soil conditioner, in parts by mass, comprising: slow-release fertilizer
30-40 part, turfy soil 20-30, Maifanitum 20-30 part, kieselguhr 15-20 part, water-retaining agent 5-10 part.
After above-mentioned each component mixing, the soil conditioner directly as Tailings Dam uses.Preparation process is simple.
By 200-300kg soil conditioner/mu Tailings Dam.
Described soil conditioner once applies.Need not repeatedly apply fertilizer.
Slow-release fertilizer is preferably calcium and magnesium phosphorus composite slow-release fertilizer.Consumption is preferably 35 parts.
Turfy soil is preferably northeast turfy soil.
The particle diameter of turfy soil is preferably 1-2mm.
The ph of preferably turfy soil is 5.5-7.5.
The content of organic matter of preferably turfy soil is 50%-70%.
The content of humic acid of preferably turfy soil is 30%-40%.
The ventilation space 27-29% of preferred turfy soil.
The consumption of turfy soil is preferably 30 parts.
The consumption of Maifanitum is preferably 25 parts.
The particle diameter of Maifanitum is preferably 80 mesh.
Diatomaceous consumption is preferably 18 parts.
Diatomaceous particle diameter is preferably 80 mesh.
The consumption of water-retaining agent is preferably 8 parts.
Described water-retaining agent is preferably starch-acrylate graft copolymer.
Water-retaining agent can be, but not limited to use:
The uncommon great waves agricultural water-loss reducer xt199 (potassium salt type water-retaining agent) that Beijing Xitao Development Tech Co., Ltd. produces, effectively
Composition starch grafting type polyacrylic acid potassium >=80%,
Board full Semen Maydis powder type agricultural water-retaining agent, (work(are praised in the sky source that Shijiazhuang Jianyuan Starch Derivative Co., Ltd. produces
Effect phase 0.5-1)；Planting lawn and maintenance: 15-30g/m2
Concrete application method: described soil conditioner is applied to improve Tailings Dam, by 200-300kg soil conditioner/
Mu Tailings Dam uniformly sows soil conditioner, turns over, and mix homogeneously is poured water to saturation, static fermentation 5-7 days.
Above-mentioned ploughed depth is more than 30cm.
Suitable moisturizing during static fermentation.
Preferably use Tailings Dam soil conditioner plantation pionner.
Tailings Dam soil conditioner is particularly preferably used to plant winter Rhizoma Imperatae.
Plant above plant and be obtained in that higher germination percentage and resultant effect.
Concrete implantation methods are: by 18-20g/m2Sowing pionner winter Rhizoma Imperatae seed, covers nonwoven after the completion of sowing
Cloth, maintenance was suitably watered according to climatic condition after 4-6 days, observed growing state.
Beneficial effects of the present invention:
The Tailings Dam soil conditioner of the present invention is easy to use, fertilizer efficiency lasting, material safety environmental protection, has preferable economy
Benefit and environmental benefit.Effectively reduce the impact to surrounding enviroment for the tailings.
In prior art, Tailings Dam bulk deposition, the difficulty that it recycles is very big, existing than more conventional method is
Heavy metal pollution of soil, fills up the planting soil that foot afforests native standard of planting on Tailings Dam, and sets up isolated system, although this method energy
To a certain extent using the soil piled up, but still inherently do not improve Tailings Dam ground condition.Additionally, prior art
In also provide some soil conditioners, but it is not good to Tailings Dam improvement, and for this present situation, inventor has been carried out greatly
Quantifier elimination, by continuous experimental exploring, has finally given the solution of the present invention.The present invention solves Tailings Dam and is tied by substrate
Structure is poor, the factor such as nutrient disappearance, heavy metal toxicity limits the relatively low problem of rate of reclaiming, and had both avoided heavy metal pollution of soil and has caused secondary breaking
Bad, improve the utilization rate of fertilizer again, the heavy metal in Tailings Dam soil is played with fixation simultaneously, reduce substrate toxicity,
Improve percentage of seedgermination, reduce the murder by poisoning to plant growing, effectively reduce the pollution to surrounding enviroment for the tailings.
