Technical field
The present invention relates to field of Environment Protection.It is more particularly related to a kind of Novel ring soil conservation
Earth heavy metal renovation agent and preparation method thereof.
Background technology
While the fast developments such as modern industrial or agricultural, the situation of heavy metal pollution of soil is the most increasingly
Severe.Its administering method is a lot, and biological restoration is just receiving publicity with its unrivaled advantage,
Have a extensive future.But it is to be solved that biological restoration still suffers from many problems, as hyperaccumulative plant is inhaled
The mechanism receiving heavy metal is not also studied clear.All these, all hinder the big rule of biological restoration
Mould is applied.
Heavy metal pollution of soil refers to the pollution that heavy metal in soil excessive buildup causes.Polluted Soil
The heavy metal of earth includes bio-toxicity significant element such as Cd, Pb, Hg, Cr, As, and
There are element such as Cu, Zn, Ni of certain toxicity.This kind of pollution range is wide, persistent period length,
Pollute hidden, cannot be biodegradable, soil degradation will be caused, under Crop yield and quality
Fall, and by runoff, leaching loss contaminating action surface water and groundwater.Excess heavy metal will be to planting
Thing physiological function produces harmful effect so that it is nutritional disorder.Hydrargyrum, arsenic can suppress nitrification in soil,
Ammonifying bacteria is movable, hinders Nitrogen supplying.Heavy metal can be enriched with by food chain and generate toxicity
Higher methyl compound, poisons food chain biology, finally at people's cylinder accumulation, endangers the mankind
Healthy so that the approaching needs of this environmental issue solves.
