Description
Technical field
Present invention relates particularly to heavy-metal contaminated soils to administer and recovery technique field, and in particular to a kind of environmental protection soil weight
Metallic stabilizer.
Background technology
China's Heavy Metals In Environment is more serious and universal, Heavy Metals In Environment not only influence crops and
The yield and quality of aquatic products, and it is related to air and quality of water environment, and the life of the mankind can be endangered by food chain and be good for
Health.It is between heavy metal different shape, different heavy metals and mutual with other pollutants in environment due to sources of heavy metal complexity
Effect, the complexity for generating various combined pollutions increases the difficulty studied heavy metal, and heavy metal is to animals and plants and human body
Harm have chronicity, potentiality and irreversibility.
Therefore, Heavy Metal Pollution Control technology will become in one period from now in the hot spot in heavy metal pollution field
Hold.In view of the above problems, China has carried out this respect research, in the hope of solving the problems, such as.Application publication number is：

CN201310677528.8 can be used to improve yield of the plants such as capsicum on heavy metal joint contaminated soil, Wu Fayou
Effect ground, which adsorbs the free heavy metal ion in soil, to be fixed, the acidity of sweetening of the soil.
2. heavy metal-polluted soil heavy metal-polluted soil renovation agent and its application-CN201310677304.7 to high pollution soil,
It can be used to improve the growing states and/or quality of the plants on heavy metal high pollution soil such as balsam pear, it equally can not be effective
Ground, which adsorbs the free heavy metal ion in soil, to be fixed, the acidity of sweetening of the soil.
3. heavy metal-polluted soil renovation agent and its application-CN201310200934.5, can chromium and/or cadmium in rehabilitating soil (and/
Or lead) pollution, improve the chromium and/or cadmium (and/or lead) residual of planted plant, and have the function of synergy, but
It is the acidity for being equally unable to sweetening of the soil, heavy metal or absorption in soil can not be made or be chelated or be degraded.
4. use in conjunction-the CN201310668985.0 of Agrotechnical formulation containing selenium and heavy metal-polluted soil renovation agent, can enhance
The effect of heavy metal-polluted soil renovation agent significantly reduces the content of the heavy metals such as the cadmium in plant (especially vegetable seeds), but not
Heavy metal in soil ion releasing can be prevented with the acidity of sweetening of the soil, while supplement the nutrition of crop needs, activating soil is anti-
Only it is passivated.
5. use in conjunction-the CN201310677949.0 of zinc selenium Agrotechnical formulation and heavy metal-polluted soil renovation agent, in addition to improving
Except plant products, additionally it is possible to enhance the effect of heavy metal-polluted soil renovation agent, significantly reduce in plant (especially vegetable seeds)
The heavy metals such as cadmium content, can not sweetening of the soil acidity, heavy metal or absorption in soil can not be made or be chelated or by
Degradation.
Various heavy passivation in soil can be stablized for this purpose, the present inventor provides one kind for soil of lying fallow, is reduced
Soil aciditiy, culture fertility, the heavy metal soil stabilizer for achieving the purpose that fertile soil, improveing soil property.
