The invention discloses a kind of soil remediation methods, processing step includes soil pretreatment-ciliate desert-grass batch nursery-ciliate desert-grass transplanting-kind kind year after year, the present invention using to arsenic there is the ciliate desert-grass of extremely strong enrichment to be administered to soil, regulation effect is more preferable, secondary pollution will not be introduced, in addition, the present invention is transplanted using strain and is planted instead of traditional grass-seed of spreading, so that the survival rate higher of rehabilitation plant, it is more preferable to the regulation effect of soil, and kind kind year after year can thoroughly administer the arsenic pollution object in soil.
Description
Technical field
The present invention relates to ecological environments to repair field, more particularly to a kind of soil remediation method.
Background technology
Ciliate desert-grass is fern Pteridaceae Pteris plant, and external survey shows that ciliate desert-grass has very strong enrichment to arsenic
Effect.But the current limitation arsenic in soil administered using ciliate desert-grass due to process so that regulation effect
It is bad.
The present invention relates to a kind of method that interplanting ciliate desert-grass eliminates soil arsenic pollution, processing steps by CN201610384481.X
Suddenly it is that applying lime on soil first, in accordance with 100~200kg/ mus adjusts soil pH value；After having applied lime, in soil overlying
The waterproof membrane of one layer of 0.1cm thickness of lid；The hardboard for covering one layer of 0.1cm thickness on waterproof membrane again, covers on hardboard later
The pollution-free soil moved in improve the original of one layer of 20~40cm；Ciliate desert-grass is interplanted in contaminated soil again；The long-term cropping in pollution-free soil moved in improve the original, and protect
The spacing of 20~100cm is kept between card and ciliate desert-grass；Ciliate desert-grass can all be pulled out after finally planting ciliate desert-grass year and a day
It removes.Contaminated soil original at this time has had reached the secondary standard in national regulation farmland.Eliminate the cost of soil arsenic pollution
Very low, it is crop and ciliate desert-grass aggregate value to create value；It is good, economic and environment-friendly with using effect, pollution administration is at low cost
The features such as.
A kind of above-mentioned method that interplanting ciliate desert-grass eliminates soil arsenic pollution of patent, the standard of improvement can only national regulation farmland
Secondary standard, regulation effect is poor.
Invention content
A kind of soil remediation method, technical process include：
(1) soil pretreatment
Arsenic soil will be contained to pre-process, according to repaired area by it area centered on destroying most serious area, in soil
Flood irrigation is carried out on earth so that the water content of soil reaches 40-65%；
(2) ciliate desert-grass batch nursery
Ciliate desert-grass seedling is filled into basin, first 1-2 centimeters of thick coarse grain matrix is put into as drainage layer at basin bottom, sprinkles one thereon
The fully decomposed organic fertilizer of layer is as base manure, and thickness is about 1-2 centimeters, then lid last layer matrix, about 1-2 centimeters thick, then
It is put into plant, pours primary permeable after upper complete basin, and is placed on shade environment maintenance；
(3) ciliate desert-grass is transplanted
The ciliate desert-grass of strain 20-35cm is transplanted on the soil of improvement to be repaired, hereafter monthly to ciliate desert-grass carry out
Primary watering and fertilising bimonthly；
(4) kind kind year after year
The upper newborn ciliate desert-grass of kind administers soil again again on the soil by the enrichment of 1 year ciliate desert-grass, this
Kind kind, the arsenic content in soil drop under level-one soil content standard 15mg/Kg year after year afterwards.
Preferably, the step (1) is to adjust acid hydrolysis to the pretreatment of repairing environment soil, detects the soda acid of soil
Degree adjusts the acidolysis degree of soil according to the acid-base property of ciliate desert-grass growing environment, to acid by the way of splash lime and plant ash
Property soil is neutralized, will be within the scope of soil ph to 6.0-7.2.
Preferably, the coarse grain matrix in the step (2) as drainage layer is：Turf+perlite++ 2 parts of haydite=2 part+
1 part either vegetable garden soil++ 1 part of clinker=3 part either turf++ 2 parts+1 part of clinker+haydite=2 part or sawdust+vermiculite+in
Thick+2 parts+1 part of river sand=2 part.
Preferably, step (2) organic fertilizer includes 3 parts of biological organic fertilizer, 4 parts of potash fertilizer, 3 parts of phosphate fertilizer.
Preferably, the planting density of step (3) ciliate desert-grass is to be divided according to improvement block：The 200m of central area half
In diameter, 30 ciliate desert-grass of every 10 square metres of plantations；In the 200m radiuses in subcenter area, 20 centipedes of every 10 square metres of plantations
Grass；5-10 ciliate desert-grass of the every 10 square metres of plantations in edge zone.
Preferably, the annual recursion of the ciliate desert-grass density of the step (4) kind kind year after year reduces 10-20%.
Advantageous effect：The present invention provides a kind of soil remediation method, processing step includes soil pretreatment-ciliate desert-grass batch
Measuring nursery-ciliate desert-grass transplanting-, kind kind, the present invention using to arsenic there is the ciliate desert-grass of extremely strong enrichment to control soil year after year
Reason, regulation effect is more preferable, will not introduce secondary pollution, in addition, the present invention replaces traditional grass-seed of spreading to carry out using strain transplanting
Plantation so that the survival rate higher of rehabilitation plant, it is more preferable to the regulation effect of soil, and kind kind year after year can be thoroughly to soil
Arsenic pollution object in earth is administered, and the step (1) is to adjust acid hydrolysis to the pretreatment of repairing environment soil, detects soil
Acid-base value, according to the acid-base property of ciliate desert-grass growing environment adjust soil acidolysis degree, using the side of splash lime and plant ash
Formula neutralizes acid soil, and by within the scope of soil ph to 6.0-7.2, which is capable of providing ciliate desert-grass growth
Suitable acid-base property so that the growth of ciliate desert-grass is more smooth, and the coarse grain matrix in the step (2) as drainage layer is：Grass
Charcoal++ 2 parts+1 part of perlite+haydite=2 part either vegetable garden soil++ 1 part of clinker=3 part or turf+clinker+haydite=2 part+
2 parts+1 part or sawdust++ 2 parts+1 part of vermiculite+mild-crude river sand=2 part, which can play the role of drainage so that pour
On the one hand water body is filtered when water so that the impurity in water body is detained, and water body is more beneficial to the growth of ciliate desert-grass, separately
On the one hand excessive moisture is exported, prevents rotten, step (2) organic fertilizer includes 3 parts of biological organic fertilizer, 4 parts of potash fertilizer, phosphorus
3 parts of fertilizer, the ingredient are capable of providing the sufficient growth nutrient of ciliate desert-grass, and the planting density of step (3) ciliate desert-grass is that foundation is controlled
Block is managed to divide：In the 200m radiuses of central area, 30 ciliate desert-grass of every 10 square metres of plantations；The 200m radiuses in subcenter area
It is interior, 20 ciliate desert-grass of every 10 square metres of plantations；5-10 ciliate desert-grass of the every 10 square metres of plantations in edge zone, this stand density energy
The enough arsenic in soil carries out efficiently concentrating, and the annual recursion of ciliate desert-grass density of the step (4) kind kind year after year reduces 10-
20%, since the arsenic content in kind kind soil year after year reduces, ciliate desert-grass can be improved by reducing the dosage of ciliate desert-grass therewith
Utilization rate saves the treatment cost of soil.
