Description
Technical field
The present invention relates to soil conditioner field, more particularly, to a kind of saline-alkali soil modifying agent and preparation method thereof.
Technical background
Salt-soda soil is a species of salt aggregation, refers to that the salinity contained by inside soil has influence on the normal life of crop
Long, according to UNESCO and food and agricultural organization's incomplete statistics, the area in whole world salt-soda soil is 9.5438 hundred million hectares,
Wherein China is 99,130,000 hectares.The formation of China's alkaline earth and alkali-affected soil, it is most of accumulative relevant with Carbonates In Soil,
Thus basicity is universal higher, and serious salt affected soil regional plant can hardly survive.Various saline alkali soils are all one
Formed under fixed natural conditions, its essence formed is mainly various ease of solubility salts and makees horizontal direction and Vertical Square on ground
To redistribute so that salinity collection salt area upper soll layer build up, influence saline-alkali soil formation it is main
Factor has：Weather conditions, geographical conditions, the soil texture and underground water, the influence in river and seawater, cultivation management it is improper etc..
Salinization of soil makes soil physico-chemical property be deteriorated, and the life condition of crop, forest and herbage degenerates, and is mainly manifested in：Soil
Earth content of organic matter relative reduction, Soil nutritional condition is deteriorated, and soil physical property is bad, and soil microbial activity is by saline and alkaline
Suppression, the soil liquid directly poisons crop cell, plant growth is bad to be caused to be short of seedling, the underproduction, death.In a word, soil is saline and alkaline
Change the edaphic condition that damage to crops depends on for existence, and the growth of misfortune and crop, cause crop to be short of seedling or dead, so as to hinder agriculture
The development of industry production, the salinization of soil is the important limiting factor of local developing agricultural economy.
In the case where current environment protects the requirement with recycling economy, find a kind of saline and alkaline using discarded object or Resource recovery progress
The technical method of ground improvement is the key point that the field is badly in need of breaking through.
At present, the technology improved on alkaline land soil has many methods, and prior art is as authorized public number
The B of CN 101624523 Chinese invention patent, discloses a kind of saline-alkali soil conditioner, this method is by aluminum sulfate, sulfuric acid
Ferrous ammonium and magnesium sulfate are matched in specific proportions to be formed, with preparing simple advantage, but it can not significantly reduce soil
PH value, it is impossible to enough organic matters are improved for salt affected soil, the inventive method formula does not contain water-loss reducer, thus can not prevent salt
The dehydration of alkaline earth earth, it is impossible to from root change salt-soda soil attribute, because rather than a kind of efficient saline-alkali soil modifying agent,
It is unworthy promoting.
The content of the invention
It is an object of the invention to provide a kind of efficient, environmental protection saline-alkali soil modifying agent and preparation method thereof.
The present invention is directed to the problem of being mentioned in background technology, and the technical scheme taken is：Saline-alkali soil modifying agent and its
Preparation method, it is constituted and its parts by weight are：650-700 parts of ecological organic fertilizer, 200-220 parts of trophic factors, water-loss reducer 12-15
Part, 37-40 parts of aluminum sulfate, 45-50 parts of sulphur, 10-12 parts of ardealite, 3-4 parts of polyvinyl alcohol, 3-5 parts of functional oligopeptide, it is organic
Eco-fertilizer not only provides the organic matter needed for improvement salt-soda soil, moreover it is possible to provide organic acid to reduce the pH value of alkaline land soil；Have
Humus in machine fertilizer can strengthen the retentiveness of soil with water-loss reducer, make loosing soil, increase porosity, trivalent aluminium ion
Exchange energy effectively reduces calcium, magnesium, potassium, the content of sodium plasma, and alkaline land soil total salt content is reduced from root,
Improve soil property.
Microorganism used therefor buys enterprise with it：Colloid bacillus cereus, Xingtai Si Beite bio tech ltd.
Saline-alkali soil modifying agent and preparation method thereof, its preparation method comprises the following steps：
The preparation of fermented cow dung：Weigh 200-250 parts of cow dung, 10-15 parts of weathered coal, 20-30 parts of alcohol slag, 40-45 parts of turf,

Degree lower uniform stirring mixing produces soil conditioner in 30-45 minutes；The amino acid sequence of functional oligopeptide is：
SCASRCKARRCRARRCGYFGKRCICKCFRC；Cow dung, furfural dregs in function conditioner contain abundant organic matter, make soil
Earth is loose, increases porosity；Cow dung, furfural dregs in function conditioner, synthesize humus, humus is with protecting in salinized soil
Aqua can strengthen the retentiveness of soil, and sulphur is that a kind of acid compound can also reduce soil pH value, multi-functional conditioner
The aluminum sulfate of middle addition is hydrolyzed to sulfate ion and aluminium ion in soil, aluminium ion replacement ability be more than divalence sun from
Son, base cation such as calcium ion, magnesium ion, potassium particle, the sodium ion of salt-soda soil colloid surface are by trivalent aluminium ion replacement to soil
In earth solution, make base cation with irrigation water leaching to substratum, thus reduce alkaline land soil total salt content, feature is few
Peptide can form complex compound with the trace element ion in solution, and then be absorbed by root system of plant, help lend some impetus to plant growth,
The salt content in soil can also be reduced simultaneously.
Described water-loss reducer is polyacrylamide or acrylate polymer or starch-polyacrylate acid salt graft polymers
Or carboxymethyl cellulose crosslinked body or acrylate acrylamide copolymer, high polymer water-loss reducer Water-saving effect preferably, and
It is environmentally friendly.
Described trophic factors is that urea, diammonium hydrogen phosphate, zinc sulfate, ammonium molybdate weight ratio are pressed into 55-57:39-40:4-
5:1 mixing, nutritional ingredient is added in proportion can play due effect and not waste.
Compared with prior art, the advantage of the invention is that：1）Raw material cow dung, weathered coal used in the inventive method,
Alcohol slag, turf, flat mushroom edible fungi residue, furfural dregs are all the accessory substance or discarded slag charge of industrial and agricultural production, not only price
It is cheap, and the full utilization of resource is realized, protect environment；2）Ecological organic fertilizer provides organic matter, organic acid and is conducive to
The soil property of saline-alkali soil is improved, alditol slag, sulphur can reduce the pH value of soil；3）The trivalent aluminium that aluminum sulfate hydrolysis are obtained from
Son has very strong replacement ability, effectively reduces the total salt content of alkaline land soil, functional oligopeptide can with solution
Trace element ion formation complex compound, and then absorbed by root system of plant, plant growth is helped lend some impetus to, therefore this modifying agent is one
Plant environmentally friendly, efficient saline-alkali soil modifying agent.
