Abstract
The invention discloses a kind of soil remediation method, comprise the following steps：（1）Contaminated soil is deep ploughed, the depth of deep ploughing is 30 40cm, then sets wide-and narrow-row, the 3m of wide row line width 2.5, the 1.5m of narrow row line width 1, the 2m of line-spacing 1.5；（2）Green grass, plant tendril are layered on wide-and narrow-row surface, and covering one layer of farm manure above；（3）The planting plants on wide-and narrow-row, keep the 1.5m of spacing in the rows 1 during plantation；（4）Earthworm is delivered into soil；（5）Deliver earthworm and collect earthworm after 30 40 days.The present invention is by the decomposition of microbe, plant heavy metal element excess accumulation, and the absorption of earthworm heavy metal element reaches the purpose of rehabilitating soil, and cost is low, and effect is good.
Description
Technical field
The invention belongs to pollutant process technical field, more particularly, to a kind of soil remediation method.
Background technology
It is excessive when being contained hazardous substance in soil, more than the self-purification capacity of soil, composition of the soil, structure and work(will be caused
It can change, though soil remediation method in the market is more, all more complicated, cost is higher.
The content of the invention
There is provided a kind of low soil remediation method of cost in order to overcome the deficiencies in the prior art by the present invention.
To achieve these goals, the present invention uses following technical scheme：A kind of soil remediation method, including following step
Suddenly：
（1）Contaminated soil is deep ploughed, the depth of deep ploughing is 30-40cm, then sets wide-and narrow-row, wide row line width 2.5-
3m, narrow row line width 1-1.5m, line-spacing 1.5-2m；
（2）Green grass, plant tendril are layered on wide-and narrow-row surface, and covering one layer of farm manure above；
（3）The planting plants on wide-and narrow-row, keep spacing in the rows 1-1.5m during plantation；
（4）Earthworm is delivered into soil；
（5）Deliver earthworm and collect earthworm after 30-40 days.
Contaminated soil is deep ploughed, the gas porosity of soil is improved, beneficial to the growth of microorganism, wide-and narrow-row, increase are set
The illuminating area of plant, lifts photosynthesis, green grass, plant tendril is layered on into wide-and narrow-row surface, and covering one layer of agriculture above
Family's fertilizer, green grass and plant tendril can be fermented in the presence of farm manure, be conducive to improving the nutrition condition of soil, beneficial to micro-
Biological growth, and microorganism can play a part of decomposing pollutant, the planting plants on wide-and narrow-row, by plant to a huge sum of money
Belong to the excess accumulation effect of element, the heavy metal element in soil can be transferred in plant, be easy to collect, delivered in soil
Earthworm was simultaneously collected after 30-40 days, by the absorption of earthworm heavy metal element, can be rich by the heavy metal in soil
Collect in earthworm body, be easy to collect, whole repair process cost is low.
Further, the farm manure is by the fermentation of poultry manure, stalk, haylage, straw and plant ash；It can show
Writing improves the nutrition condition of soil, is conducive to the growth of microorganism.
Further, the density for delivering earthworm is every mu of 20000-30000 bar；Deliver density larger, strengthen counterweight
Metal enrichment is acted on.
In summary, the decomposition of the invention by microbe, plant heavy metal element excess accumulation,
The absorption of earthworm heavy metal element reaches the purpose of rehabilitating soil, and cost is low, effect is good.
Embodiment
In order that those skilled in the art are better understood from the present invention program, to the technical side in the embodiment of the present invention
Case carries out clear, complete description.
Case one
A kind of soil remediation method, comprises the following steps：
（1）Contaminated soil is deep ploughed, the depth of deep ploughing is 30cm, then wide-and narrow-row be set, wide row line width 2.5m is narrow
The wide 1m of every trade, line-spacing 1.5m, heavy metal element is typically at soil higher depth in the presence of rainwater, can be by depth by deep ploughing
Place's contaminated soil is ploughed to surface, is set wide-and narrow-row to be beneficial to plant and is carried out photosynthesis.
（2）Green grass, plant tendril are layered on wide-and narrow-row surface, and covering one layer of farm manure above, specifically, the institute
Farm manure is stated by poultry manure, stalk, haylage, straw and plant ash ferment；Farm manure is covered in green grass, rattan of plant
Climing green grass and plant tendril can ferment in the presence of farm manure above, further improve the nutrition condition of soil, increase micro- life
The content of thing, and by the decomposition of microbe, reduce the content of Soil Microorganism.
（3）The planting plants on wide-and narrow-row, keep spacing in the rows 1m during plantation, plant can be long-pending by the excess of heavy metal element
Tired effect, heavy metal is collected out from soil and itself is stored in vivo, is easy to people to collect
（4）Earthworm is delivered into soil, the density for delivering earthworm is 20000 every mu, made by the absorption of earthworm heavy metal
With can be by heavy metal accumulation to earthworm body.
（5）Deliver earthworm and collect earthworm after 35 days, can be to being passed through hot-air in soil, in the effect of hot-air when collecting
Lower earthworm can climb out of out of soil, and then be convenient for people to be collected.
Case two
A kind of soil remediation method, comprises the following steps：
（1）Contaminated soil is deep ploughed, the depth of deep ploughing is 30cm, then wide-and narrow-row be set, wide row line width 2.5m is narrow
The wide 1m of every trade, line-spacing 1.5m, heavy metal element is typically at soil higher depth in the presence of rainwater, can be by depth by deep ploughing
Place's contaminated soil is ploughed to surface, is set wide-and narrow-row to be beneficial to plant and is carried out photosynthesis.
（2）Green grass, plant tendril are layered on wide-and narrow-row surface, and covering one layer of farm manure above, specifically, the institute
Farm manure is stated by poultry manure, stalk, haylage, straw and plant ash ferment；Farm manure is covered in green grass, rattan of plant
Climing green grass and plant tendril can ferment in the presence of farm manure above, further improve the nutrition condition of soil, increase micro- life
The content of thing, and by the decomposition of microbe, reduce the content of Soil Microorganism.
（3）The planting plants on wide-and narrow-row, keep spacing in the rows 1.5m during plantation, plant can be by the excess of heavy metal element
Summation, heavy metal is collected out from soil and itself is stored in vivo, is easy to people to collect.
（4）Earthworm is delivered into soil, the density for delivering earthworm is 30000 every mu, passes through the suction of earthworm heavy metal
Adduction, can be by heavy metal accumulation to earthworm body.
（5）Deliver earthworm and collect earthworm after 40 days, can be to being passed through hot-air in soil, in the effect of hot-air when collecting
Lower earthworm can climb out of out of soil, and then be convenient for people to be collected.
Obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
