Description
Technical field
The invention belongs to soil conditioner preparation field, and in particular to a kind of preparation method of multifunction soil improver.
Background technology
In recent years, due to the shortage of water resource, irrational utilization and irrational farming, China's desertification of land is increasingly
Seriously, long-term irrational use chemical fertilizer is added, the disadvantages such as soil hardening, soil fertility decline, ecological disruption are even more caused.
Soil texture is easy for causing soil liquid manure to be lost in seriously, so as to reduce fertility, greatly hindered once destruction
The benign cycle that ecological environment is produced with agriculture forest and husbandry.Therefore, how to keep soil quality and increase soil fertility to become
Focus of concern.Soil conditioner is used in soil, agricultural production crisis, conditioned soil can be alleviated to a certain extent
Earth structure, strengthens the gas permeability of soil.
Current soil conditioner has four species：Natural amendments, artificial synthesized soil modifying agent, natural synthetic copolymer
Modifying agent and biological modification agent.Natural amendments are divided into inorganic material and organic materials, wherein inorganic material master by feedstock property
To include natural minerals（Lime stone, montmorillonite, gypsum, vermiculite, perlite etc.）And inorganic solid waste（Flyash etc.）；Have
Machine material mainly includes machine solid waste（Paper mill sludge, city sewage and sludge, domestic waste, crop material, pulse family
Green manure and feces of livestock and poultry etc.）, naturally extract high-molecular compound（It is polysaccharide, cellulose, resin glue, tannic acid, humic acid, wooden
Element etc.）With organic matter material（Peat, charcoal etc.）.Artificial synthesized soil modifying agent is to simulate the artificial synthesized high score of natural amendments
Sub- organic polymer.Study both at home and abroad and the artificial synthesized soil modifying agent of application has polyacrylamide, polyvinyl alcohol resin, gathered
Vinyl alcohol, polyethylene glycol, Lauxite etc., wherein polyacrylamide are the artificial synthesized soil improvement that researcher pays close attention to the most
Agent.Natural synthetic copolymer modifying agent mainly include humic acid-polyacrylic acid, cellulose-acrylamide, Starch-acrylamide/
Propylene acrylonitrile, zeolite/attapulgite-acrylamide, lignosulfonate-vinyl acetate etc..Biological modification agent includes some business
Biocontrol agent, microbial inoculant bacterium, mycorhiza, aerobic heap tea making, earthworm of industry etc., wherein it is clump branch bacterium that research application is more
Root.Above soil conditioner all has preferable reclamation result, but function is all relatively simple, or with water-holding property,
Organic matter is provided, decomposed or providing microorganism, it is impossible to which synthesis reaches multi-functional improved effect.
Patent No. ZL201210074181.3 inventor's woods Hamming etc. has invented a kind of water-loss reducer of geobiont enzyme
Preparation method, although water-loss reducer made from this method has effects that retain water and nutrients, because it mainly make use of biology
Enzyme easily occurs to go bad as main component, is difficult storage and transport.
Patent No. ZL00106098.8 Chinese patent literature disclose it is a kind of water suction, function of fertilizer retention are played to plant,
Promote the soil conditioner of plant growth, it is by polyacrylamide resin, silicate magnesium powder, urea and silica sand stone carrier filler
Composition, this soil conditioner improves the effective percentage of fertilizer, reduced while soil water sorption, fertilizer conservation is solved the problems, such as
Invalid loss.But this soil conditioner is a kind of physical mixing, the nutrient added is also easy to run off, and is only fitted
For thirsty fields, for other kinds of soil（Such as acid, alkalescence or the soil of heavy metal pollution）Then effect is not good.
The Chinese patent literature of Application No. 200910193692.5 disclose a kind of heavy metal contaminated soil conditioner and
Plant and chemistry combined remediation method, the modifying agent are the composition comprising red mud and white lime, and the plant and chemistry
Chemical method in combined remediation method is that pH value regulation is carried out to soil, and phytoremediation is that plantation energy crop and ultraproduct are tired
Plant etc. is adsorbed to the heavy metal in soil, so as to play improved soil characteristic, the heavy metal that gradually reduces in soil contains
The effect of amount, is finally reached the purpose of rehabilitating soil, improves the efficiency of phytoremediation.But this soil conditioner is in fact
A kind of ground caustic, it is main to play regulation soil pH value, the effect of removing heavy metals is can be only achieved with reference to the suction-operated of plant, and
And this soil conditioner does not possess water conservation and fertilizer conservation performance, also only for single land type on effective object,
The soil of heavy metal pollution is suitable only for, for can not then be played comprehensive improvement result by multiple contaminated land.
Therefore, invent a kind of multi-functional and to can be suitably used for polytype contaminated soil modifying agent be very urgent
's.
