Description
Technical field
The invention belongs to farmland site remediation technology fields, and in particular to a kind of soil conditioner and its method of administration.
Background technique
Most of cadmium exists all in the form of greenockite in nature, but with the continuous development of society, cadmium is extensive
Applied to nuclear industry, battery industry, electroplating industry, plastics industry etc..Some scientists study discovery soil cadmium content both at home and abroad
It is exceeded, it will lead to agricultural output and quality decline, limit the sustainable development of planting industry.Animal and most people are come
It says, diet intake is the primary approach of cadmium exposure.The World Health Organization provides that human body is 1ug/ to the maximum permissible intake (MPI) of cadmium
(Kgd), various countries also all define the limitation index of the cadmium content in cereal crops.
In the research that Environmental Cadmium Pollution damages human health, general artificial urine cadmium is the important indicator of interior exposed cadmium.People
The dosage of contained cadmium can lead to people's death up to 0.35-0.50g in vivo.Cadmium has larger harm to human body, can by respiratory system and
Digestive system, which enters human body, leads to slow poisoning and acute poisoning.Cadmium is classified as tool by 20th century United Nations Environment Programme (UNEP)
There are the dangerous chemicals of global meaning.
Therefore it provides a kind of soil conditioner processing passivation chromium is necessary.
Summary of the invention
The purpose of the present invention is to provide a kind of soil conditioners, can effectively inhibit the migration of heavy metal in soil,
The heavy metal being passivated in soil, farmland site remediation effect is obvious, effectively facilitates rice absorbing microelement.Moreover, raw material is simple
Single, improvement soil significant effect.
The present invention also provides a kind of method of administration of soil conditioner.
Specific technical solution of the present invention is as follows:
A kind of soil conditioner, the raw material including following parts by weight：
0-50 parts of calcareous fertilisers, 0-30 parts of fertiliser containing magnesium, 0-40 parts of potash fertilizer, 5-50 parts of siliceous fertilizer, 5-10 parts of humic acid and attapulgite
5-10 parts.
Preferably, the calcareous fertilisers include dolomite dust, calcium oxide, conch meal, potassium feldspar, land plaster, zeolite powder, calcium carbonate
Or one or more of calcium hydroxide.
The conch meal refers to shell by the smashed powder of high-temperature calcination, and 95% main component is calcium carbonate.
Preferably, the fertiliser containing magnesium includes dolomite dust, magnesia, magnesia, magnesium chloride, magnesium hydroxide, dolomite containing magnesium
Or one or more of magnesite.
The main component of the magnesia is magnesia, using magnisite as raw material, is forged at a temperature of 800~850 DEG C
It burns, is a kind of air-setting cementing material of fine-powdered.
Preferably, the potash fertilizer includes potassium feldspar, potassium dihydrogen phosphate, sylvite, carnallite, kainite, anhydrous potassium magnesium
One of alum, polyhalite, leonite, picromerite or potassium water glass are a variety of.
Preferably, the siliceous fertilizer includes flyash, red mud, trisiloxanes, disiloxane, polysiloxanes, sodium metasilicate or water
One of glass is a variety of.
The flyash is the fine ash that catching is got off from the flue gas after coal combustion, and flyash is the master of coal-burning power plant's discharge
Want solid waste.
The red mud is that aluminium industry extracts the waste residue being discharged when aluminium oxide.
The humic acid water solubility content of humic acid (butt) >=60%, granularity are 20-120 mesh.
The attapulgite granularity is 100-200 mesh.
The commercially available acquisition of above-mentioned all material, or can be obtained according to producer's self-condition by prior art preparation.
The preparation method of above-mentioned soil conditioner is：Each raw material is uniformly mixed through batch mixer according to formula ratio, crosses 100 mesh
Sieve to get.
A kind of method of administration of soil conditioner provided by the invention, specially：By soil conditioner spreading to be processed
Upper soll layer, then according to turn over agitating mode by soil to be processed together with the conditioner of spreading thereon turn over stirring 2-3 times, turn over
Turning depth is 18-25cm.
Further, the soil conditioner dosage is applied according to 100-200Kg/ mus.
Further, application soil conditioner is sowed again after handling soil 6-10 days.
It is right based on agricultural land soil and two aspect of crops provided by the present invention for administering in the formula of farmland site remediation
Heavy metal substance is passivated, to reduce cadmium content in crop and fruit.Improve soil pH value, cation exchange capacity (CEC) (CEC) etc.
Physicochemical property, by heavy metal in soil from, to not converting using state, reducing its activity and migration in the soil using state
Property, to reduce the biological toxicity of heavy metal-polluted soil and reduce its migration and accumulation in crop products.Firstly, institute
With soil conditioner in alkalinity, soil pH value can be effectively improved, the migration of heavy metal can be reduced.Secondly, containing a large amount of in formula
Calcium ions and magnesium ions, calcium ions and magnesium ions easily form competitive Adsorption with cadmium ion, facilitate crop and reduce absorption to cadmium, while calcium and magnesium is
The indispensable element of crop, the calcium ions and magnesium ions in formula can be sustained in agricultural land soil, and sustainable release calcium ions and magnesium ions improve agriculture
Field fertility persistently acts on crop；Again, attapulgite is contained in formula, attapulgite is porous structure, has huge ratio
Surface area, easily absorption passivation cadmium ion, obstruct absorption of the crop to cadmium；4th, contain humic acid in formula, it is mixed with potash fertilizer
Afterwards, it is easily absorbed by crops, has the function of fertilizer synergistic, improvement soil, stimulation plant growth, improvement agricultural product quality etc., in addition,
Humic acid also has preferable suction-operated to cadmium, can effectively reduce effective cadmium in soil；5th, it is appropriate in formula to joined
Siliceous fertilizer, siliceous fertilizer have important trophism to crop, are conducive to the photosynthesis for improving crop, and enhancing crop supports pest and disease damage
Anti- ability improves the lodging tolerance of crop, effectively prevents the root rot of crop, plays the role of improving crop quality, crop field
Each position silicon concentration in top increases, therefore silicon promotes crop overground part cadmium concentration to reduce in the Energy Deposition of crop overground part.
Compared with prior art, a kind of soil conditioner raw materials for production of offer of the invention are mostly natural minerals composition,
Inexpensive, materials are easy.The soil conditioner of production contains calcium, magnesium, potassium, siliceous fertilizer etc., and effective activation simultaneously supplements soil because of acid
Change the nutrients such as fixed calcium, phosphorus, potassium, can achieve the effect of balance fertilizing in use.The production of this soil conditioner
Mode is simple, it is easy, with the prospect being widely popularized.
