Description
Technical field
The invention belongs to the technical field of agricultural fertilizer, more particularly to a kind of functional fertilizer of energy repairing heavy metal in soil
Material.
Background technology
With modern society and the quick and extensive development of industry, a large amount of waste water, waste gas, solid waste are produced therewith
The modern industrialization pollutant such as thing, causes to have a strong impact on to human society and Global Ecological.And among these especially with soil pollution most
For protrusion, because soil also brings up the mankind while carry the mankind.Heavy metal pollution of soil is the one of modern industrial society
Big disastrous effect, first contaminated soil, and then polluted source；Secondly by biological chain, it is enriched with plant, animal and the mankind.Plant,
Special crops, are animal and the main food source of people, therefore plant is the initial victim of heavy metal pollution of soil, by
It is also the main undertaker that heavy metal pollution of soil is caused harm in the presence of bioconcentration.Heavy metal pollution of soil is caused harm plant
The principle of thing is that root system of plant is absorbed can produce toxic action after the heavy metal in soil to the eubolism of itself,
Such as absorption of the activity of influence metabolic enzyme, the transhipment of the other mineral elements of interference and the necessary element of influence etc..Due to plant
Eubolism is interfered, and can not obtain from soil must nutrient, directly result in root system and be damaged, yield and
Quality is affected, and plant life cycle shortens, or even premature death.Due to there is the weight in biological chain, soil in nature
Metal can be enriched in animal and human body with food chain transport, in turn resulted in and caused harm.If the heavy metal in soil can not
Remove effectively and in time, eventually seriously endanger the development of human society.In consideration of it, heavy metal pollution of soil just increasingly by
To the concern of people, the Significant Problems of Eco-environment faced as the whole society, research of the associated restoration with administering field is also existing
The emphasis paid close attention to for scientific worker.For the sustainable development of modern agriculture, ensure food safety, heavy metal pollution of soil is repaiied
Multiple and improvement is the unavoidable reality of modern society.
It is currently applied to heavy metal-polluted soil reparation and the measure administered, from being divided into three kinds in nature：Physical method, chemistry side
Method and biological method.Physical method, mainly by way of electromagnetism, the mode of elution, the mode of soil removal and replacement.Electromagnetism transfer is removed
Heavy metal is to make heavy metal ion displacement either heavy metal is quickly volatilized using electric heating environment using electromagnetic environment, this
To having certain restriction using scale, and there is certain damage to soil.The mode of elution is to be transferred to heavy metal from solid phase
In liquid phase, the heavy metal in recycling liquid phase is relatively ripe, but the big consuming of quantities is more.The mode of soil removal and replacement is mainly
Polluted Soil layer depth is turned over or changed, but quantities is big and cures the symptoms, not the disease.Chemical method, mainly adds one in soil
The material of wherein heavy metal physicochemical property can be changed a bit so that heavy metal occur precipitation, absorption, redox etc. react or
Effect, so reduces mobility, absorbed power and the degree that causes harm of heavy metal in soil.Chemical method is also can not be thorough
Solution heavy metal pollution problem be only to change heavy metal because heavy metal is not separated exclusion by this method from soil
Existence in soil, if improper measures are it is also possible to cause secondary pollution.Biological method, mainly utilizes plant absorption
The characteristic of enriching heavy metal.Comparatively rehabilitation cost is relatively low for this method, is adapted to large-scale application, can produce good Ecological Effect
Should, but this method is time-consuming that longer, efficiency is relatively low, specific mechanism of action is fuzzy, useful plant exploitation is urgently to be resolved hurrily.On
The situation of heavy metal pollution of soil can be repaired and improve to a certain extent by stating several method mode, but shortcoming is also bright
Aobvious.So, it is with low cost, repair efficiently, measure is simple, the method that has good ecological environment benefit is that heavy metal-polluted soil is dirty
Dye is repaired and pursuing a goal for administering.
Soil is no longer suitably cultivated by after heavy metal pollution, unless heavy metal contaminants therein are eliminated, is otherwise
Make to have harvested, also can be the agricultural product of heavy metals exceeding standard, it is impossible on the dining table for entering people.And as a reparation huge sum of money
Category, individually progress soil remediation is no doubt feasible, but if rehabilitating soil be able to can be received while healthy food is harvested
Ecological benefits and economic benefit bumper harvests, here it is being worth the problem of research.
