Description
Technical field
The present invention relates to technical field of soil remediation, specially a kind of actic region plant restoration method.
Background technique
Source of heavy metal pollution source in soil is complicated, first is that atmospheric sedimentation is come from, the heavy metal main source in atmosphere
In gas and dust that the production of the energy, transport, metallurgy and construction material generates；Second is that enter the heavy metal of soil with sewage, benefit
It is an ancient technology of Irrigation farming with sewage irrigation, mainly sewage is utilized as iirigation water source, due to China
Industrial boom, industrial and mining enterprises' sewage is discharged into sewer and sanitary sewage dual disposal without shunting processing, to cause
The content of irrigating region heavy metal-polluted soil increases year by year；Third is that enter the heavy metal of soil with solid waste, solid waste species
Class is various, complicated component, and variety classes and its hazard approach and pollution level are different, and wherein mining industry and industrial solid castoff are dirty
It contaminates the most serious, in the stacking or treatment process of this kind of waste, due to solarization, drenches with rain, washes heavy metal and easily move, with spoke
Penetrate shape, funnel-form is spread to surrounding soil, water body；Fourth is that enter the heavy metal of soil with material used for agriculture, pesticide, chemical fertilizer and mulch
It is important material used for agriculture, great impetus is played to the development of agricultural production, but long-term unreasonable application may also be led
Cause heavy metal pollution of soil.That pays close attention in reality often concentrates on several Heavy Metallic Elements: Hg, Cd, Pb, Cr, Cu, Zn and
As.Heavy metal pollution of soil is to influence one of human health and the major issue of environment, therefore find suitable method and control now
It is extremely urgent to manage heavy metal pollution.
Now, with the rapid development of industry, not enough prevention is expected to industrial negative effect due to people
It is unfavorable, result in the big crisis of global three: shortage of resources, environmental pollution, ecological disruption.Environmental pollution refers to natural or artificial
Destruction, add certain substance into environment and be more than the self-purification capacity of environment and generate the behavior of harm.Such as mining site is opened
It adopts and the discharge wantonly of trade effluent does great damage to surrounding enviroment, including the heavy metal pollution to soil,
Therefore the present invention provides a kind of soil remediation method for actic region.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of actic region plant restoration methods, have at low cost, improvement
The advantages that effect is good and Objective is strong, solving mining site exploitation or industrial pollution leads to asking for Soil Surrounding heavy metal pollution
Topic.
The technical solution adopted by the present invention to solve the technical problems is: a kind of actic region plant restoration method, including with
Lower step:
S1, random and continuous multiple soil sampling is carried out to the soil for the actic region administered, and is examined
It surveys；
S2, the heavy metal analysis obtained by soil sampling in S1 step are as a result, multiple regions will be divided on actic region；
After S3, the region division according to conducted in S2, planted according to plant is chosen the characteristics of dividing region；
S4, the division result according to S2 carry out the adjustment of pH value to the soil divided in region；
S5, plant selected in S3 is planted, and applies nitrogenous fertilizer and auxiliary agent is cultivated；
S6, sample detecting is carried out to plant in division region, the intracorporal content of beary metal of plant is detected；
S7, according to the testing result in S6, gathered in the plant planted in region is divided；
S8, the plant that harvesting obtains is handled.
Further, after carrying out region division in the S2 step, arrangement of digging is carried out to the soil divided inside region.
Further, the plant that the S3 chooses can choose plant according to testing result in S1, such as select for the absorption of lead
Indian mustard etc. is taken, penny cress etc. is chosen in the absorption for cadmium.
It further, is 4.3~5.8 to the range of P in soil H value adjustment in the S4 step.
Further, auxiliary agent selected in the S5 step includes humic acid and plant growth-promoting rhizobacteria etc..
The beneficial effects of the present invention are:
The actic region plant restoration method, have it is at low cost, secondary pollution is easily controllable, vegetation formed after have protection table
Soil is reduced and is corroded and the effect of soil erosion, can large-area applications in the reclaiming of mine, the vegetation in heavy metal pollution place and scape
It sees and repairs, while by the division to target area, to form multiple individual regions or multiple overlapping regions, improve and administer
Objective and regulation effect.
