Description
Technical field
The present invention relates to tailings to repair field, more particularly to a kind of rich in heavy metal tailing phytoremediation.
Background technology
In recent years, with economic and society development, demand of the entire society to resource increasingly increases, so as to cause exploitation
Amount is substantially improved, and what many mining sites were exceedingly fast, which be produced, finishes, i.e., will be retired or retired.All kinds of mining sites are in its retired premise
When for plurality of heavy metal, while solid waste-tailing harmful to local resident and animals and plants is also left after retired.This
Not only content of beary metal is high for class tailing, while destroying that the duration is long, and great destruction is brought to local Ecological environment.
Invention content
Present invention aims to solve the deficiencies of the prior art, and provides a kind of one kind being rich in heavy metal tailing phytoremediation.
The technical solution adopted by the present invention is：One kind being rich in heavy metal tailing phytoremediation, includes the following steps：Step
Rapid one, it plants the first tolerant plant according to 15~35 plants every square metre of density and plants group, first tolerant plant plants group
Any two or two kinds or more in dish, common vetch are sold including ashamed indigo plant of reviving, teasel root chrysanthemum, hardship；Step 2: according to every square metre 10~20
The density of strain plants the second tolerant plant and plants group, and the second tolerant plant plantation group is later than the first patience plantation group 3~5
Month, the second tolerant plant plantation group includes any two or two kinds or more in cogongrass, lady's-grass, Chinese herbaceous peony, annual fleabane herb；Step
Three, assist mating plantation group according to 1~3 plant every square of density plantation, the mating plantation group of auxiliary include camphor tree, tea tree,
Any two in ginkgo or two kinds or more；Step 4: periodically applying phosphate fertilizer and insecticide.
As a further improvement on the present invention, separation net and bird-scaring unit are set on flora periphery.
The advantageous effect that the present invention uses is：The phytoremediation of the present invention, it is subtle by the method for planting plants
The environment for repairing tailing ground, have the characteristics of using easy, economical and practical, suitable large area repair.
Specific implementation mode
With reference to embodiment, the present invention is described further.
Embodiment 1, one kind being rich in heavy metal tailing phytoremediation, include the following steps：
Step 1: planting the first tolerant plant according to 15~35 plants every square metre of density plants group, first tolerant plant
Plantation group includes that ashamed indigo plant of Soviet Union, teasel root chrysanthemum, hardship sell any two or two kinds or more in dish, common vetch；First tolerant plant plants group
In ashamed indigo plant of Soviet Union, teasel root chrysanthemum, bitter dish, the common vetch Four Plants sold it is high to the transfer ratio of Cu, Zn, Cd, Pb and with being relatively enriched with by force
Ability.Transfer ratio refers to the ratio of aboveground vegetation part and under ground portion content of beary metal, is typically used for weighing plant pair
The turn-over capacity of heavy metal.
Step 2: planting the second tolerant plant according to 10~20 plants every square metre of density plants group, second patience
Planting group is later than the first patience plantation group 3~5 months, the second tolerant plant plantation group include Horseweed Herb, honeysuckle,
Any two in Vitex negundo var cannabifolia, Chinese sumac or two kinds or more；Cogongrass, lady's-grass in second tolerant plant plantation group, Chinese herbaceous peony, annual fleabane herb
It is high to the transfer ratio of Co, Cu, Pb, Zn and there is stronger accumulation ability.Legume its own have the function of strong nitrogen, standing grain
Ochnaceae plant propagation ability is strong, its own can be enable to survive in tailing area and expanded.
Step 3: assisting mating plantation group, the mating plantation group packet of auxiliary according to 1~3 plant every square of density plantation
Include any two in camphor tree, tea tree, ginkgo or two kinds or more；It is the means using plant to assist the effect of mating plantation group
Improve the pH value of soil, while preventing the close of various insects and toy.Camphor tree, tea tree and ginkgo are acidproof plant
Object can improve the acidity of soil, reduce pH value.Show that being changed significantly for pH value influences the platymiscium of resistance to a huge sum of money pair through correlative study
The absorption of heavy metal, heavy metal enters the soil liquid in ADSORPTION STATE under low pH value, can increase plant and be obtained to the biology of heavy metal
Taken amount.
Step 4: periodically applying phosphate fertilizer and insecticide, the use of phosphate fertilizer can enhance plant to the absorbability of arsenic, insecticide
Use be to kill the insect entered, to prevent insect from accumulating heavy metal element at it in vivo by the sucking plant by, in turn
Tailing area is taken out of to spread to periphery.
Toy around in order to prevent enters tailing phytoremediation area, and by elements such as heavy metals by accumulating in vivo
It takes out of, separation net and bird-scaring unit is set on flora periphery, drive all kinds of animals, and then tailing is isolated and repairs area.
Transfer system of the heavy metal element in plant in all kinds of common tailings is collected by testing laboratory test
Number and concentration coefficient, to make reference.
The phytoremediation of the present invention has by the environment for repairing tailing ground that the method for planting plants is subtle
Using it is easy, economical and practical, be suitble to large area repair the characteristics of.
Those skilled in the art, can also be it is to be understood that the protection scheme of the present invention is not limited only to the above embodiments
Various permutation and combination and transformation are carried out on the basis of above-described embodiment, under the premise of without prejudice to spirit of that invention, to the present invention
The various transformation carried out are all fallen in protection scope of the present invention.
