Description
Technical field
The present invention relates to a kind of biological organic fertilizer, more particularly to a kind of biological organic fertilizer for improving Cadmium Pollution in Soils, belong to
Agricultural technology field.
Background technology
Heavy metal in soil is mainly derived from parent soil material and mankind's activity, and the activity of the mankind mainly includes industrial and mining enterprises
The waste water and gas and waste residue of discharge, a large amount of of sewage irrigation and agricultural chemicals and chemical fertilizer use etc..
Murder by poisoning of the heavy metal in soil to plant and the pollution level to environment, on the one hand with the content of heavy metal in soil
It is relevant, it is on the other hand relevant with heavy metal element form present in soil.Existing forms of the heavy metal in soil are different,
Its biological effectiveness also makes a big difference.And biological effectiveness of the heavy metal in soil depends primarily on heavy metal in soil
The content of middle available state.The form of heavy metal in soil can be divided into exchangeable species, carbon according to its existence form in soil
Hydrochlorate reference state, Fe-Mn oxide, organic matter reference state and residual form.Wherein, the heavy metal of exchangeable species is very active, to ring
Border conversion is sensitive, is easily released also easily to react and is converted into other forms, is easily absorbed for crop；Carbonate combine state
Heavy metal to pH sensitive, pH value is easily released in soil when declining, and may cause the secondary pollution to environment.Ferrimanganic
Oxidation state is easily influenceed by soil pH value and Eh values, can be discharged under the reducing conditions；Organic matter reference state be heavy metal-polluted soil and
Various organic substance chelatings form in soil, and release process is slow, and residual form heavy metal is present in clay lattice more, with sinking
Product thing combination is most firm, can not be extracted with general extracting method, and his activity is minimum, and validity is also minimum.
At present, the approach for administering heavy metal pollution of soil both at home and abroad mainly removes heavy metal from soil, Yi Jigai
Become valence state and form of the heavy metal in soil, reduce its migration and biological effectiveness in the environment.The former is mainly applicable
In the serious soil of heavy metal pollution, the latter is primarily adapted for use in the light, soil of moderate heavy metal pollution.Administer and restorative procedure has
Chemical restoration, Agro-ecology recovery technique, bioremediation technology, solidification recovery technique, combined remediation technology etc..Such as：It is blunt
Agent is added in soil, is complexed with soil, is precipitated, absorption, ion exchange and a series of redox reaction, is subtracted
The mobility of few heavy metal and the bioavilability of heavy metal contaminants, reach reparation purpose.Conventional passivator includes lime
Property material, organic fertilizer, Carbon Materials, clay mineral, phosphorated material and agricultural wastes etc..
Wherein, Carbon Materials include a kind of highly stable carbonaceous organic matter such as charcoal, activated carbon, in alkalescence and with big
Micro-pore to be measured, while there is substantial amounts of surface negative charge, larger specific surface area, abundant carboxyl is contained on its surface, phenolic hydroxyl group,
The materials such as lactone group oxygen-containing functional group, heavy metal can be adsorbed.Therefore, it is manured into soil abundant suction using charcoal in the prior art
Attached heavy metal element and improved soil physicochemical character.But charcoal content containing mineral nutrient is low, its direct nutrient effect is that have
Limit, therefore charcoal will be mixed with fertilizer and applied, such fertilizer eliminates the defects of charcoal nutrient is low, and charcoal assigns fertilizer
The complementation of nutrient slowly-released performance and synergy.
But use charcoal to be mixed with bio-feritlizer and apply Shortcomings：First, influenceed after charcoal mixes with bio-feritlizer
The release of fertilizer and absorbed, reduce utilization rate；Secondly, the service life of charcoal is shorter, needs in use for some time
Change, not only practical operation bothers, also portable to take away bio-feritlizer；In addition, the use of charcoal is easily caused soil hardening, lead
Cause regeneration difficult.
