Abstract
The invention discloses a method for remedying heavy metal polluted mining soil, which includes: using fish-scale pits to prepare the land; separately stacking the soil of different stratums in excavation; separating the surface soil and the undersoil; allowing unpolluted soil to stand by; filling the finished tree pits with the surface soil obtained in excavating the tree pits; well mixing the tree pit filling with the unpolluted soil excavated on the spot or borrowed soil, and filling the mixture into the tree pits; and finally filling with the undersoil or borrowed soil. On the basis of the prior art, ingredients of the filling are changed, so that planted plants are easy to survive and can successfully live through the transitional period, and the basis for remediation later is laid.
Description
Technical field
What the present invention relates to is the method for a kind of repairing heavy metal pollution mining area soil.
Background technology
At present, the green reparation of heavy metal pollution mining area soil is mainly the plantation heavy metal accumulation plant in the heavy metal pollution mining area, through the absorption of enriching plant; Reach the purpose of reparation, yet, in the quite high area of heavy metal concentration; The survival rate of enriching plant can not get guaranteeing that tracing it to its cause is that plant needs a phase buffer after being transplanted to the contaminated area, if direct transplanting is to the heavily contaminated area; Even high enriching plant is not if the chance that can not get cushioning still can adapt to new environment.
Summary of the invention
The present invention is directed to existing deficiency the method for a kind of repairing heavy metal pollution mining area soil is provided.
The present invention realizes above-mentioned purpose through following method.
The method of a kind of repairing heavy metal pollution mining area soil adopts whole ground, fish scale pit, different levels soil pile up separately when digging pit, and table soil separates with subsoil, and pollution-free soil is subsequent use; In excavating good tree well, insert the table soil that digs out when excavating tree well earlier; Pollution-free soil that then tree well filler and original position is dug out or soil moved in to improve the original mix to be inserted in the tree well, inserts subsoil or soil moved in to improve the original again, the long 40-60 of described tree well centimetre, wide 40-60 centimetre, dark 50-70 centimetre; Soil in the tree well is made up of top layer, intermediate layer and bottom; Skin depth is 5-15 centimetre, and underlayer thickness is 5-15 centimetre, and intermediate layer thickness is 20-40 centimetre; The top layer is subsoil or soil moved in to improve the original, and the intermediate layer is that pollution-free soil or the soil moved in to improve the original that filler and original position are dug out evenly mixes, and bottom is table soil or soil moved in to improve the original, and the filler of each tree well input is a compoiste fertilizer; Described compoiste fertilizer is made up of the composition of following weight ratio: potassium sulphate 25-40 part, ammonium sulfate 30-35 part, high calcium clay 2-4 part; Diammonium phosphate 20-25 part, fulvic acid 10-15 part, soluble chitosan 1-4 part; Organic waste 50-60 part, micro-4-7 part, perlite 5-10 part; Vermiculite 3-6 part, fenaminosulf 1-3 part, tpn 2-4 part.
Described organic waste is: one or several mixtures of branch, dry branches and fallen leaves, wood chip, peat, municipal sludge;
Described trace element is Cu, Fe, Mn, B, the Mo mixture of equivalent.
The weight of said filler accounts for the soil of tree well and the 20-30% of filler gross weight.
Compoiste fertilizer preferably is made up of the composition of following weight ratio: 32 parts of potassium sulphates, 33 parts in ammonium sulfate, 3 parts of high calcium clays, 22 parts of diammonium phosphate; 13 parts of fulvic acids, 2 parts of soluble chitosans, 55 parts of organic wastes, 5 parts of trace elements; 7 parts of perlites, 5 parts of vermiculites, 2 parts of fenaminosulf, 3 parts of tpns.
Beneficial effect
The present invention has the following advantages:
(1) the present invention changes the composition of filler on the basis of existing technology, makes the plant of being planted become alive easily; Successfully tide over phase buffer, for reparation afterwards lays the first stone, specifically; Using increasing the soil organic matter of filler of the present invention improved soil physico-chemical property and will be got positive effect, set up fenaminosulf and tpn; Under the prerequisite that increases the soil organic matter, reduced the probability of plant infection damage by disease and insect; Various fertilizer and perlite, vermiculite are carried out reasonable formula, and scientific formulation is reasonable, wide accommodation; Fertilizer efficiency is powerful lasting; This season availability is high, and perlite, vermiculite in the prescription have obvious improved effect to the soil texture, and various plant transplantation survival rates are increased substantially;
(2) method of planting of the present invention is excavated planting pit for adopting whole ground, fish scale pit, utilizes to put soil or soil moved in to improve the original and mixes with filler and carries out the hillside fields tree planting.This method of planting is simple, has the sapling survival rate of raising and growth rate, has rehabilitating soil and vegetation, reduces the effect of water and soil loss.
