Description
Technical field
The present invention relates to fertilizer field, more particularly to a kind of alkaline land modifying agent and preparation method thereof.
Background technology
Alkaline land modifying agent nutrient comprehensively, can improved soil, improve the soil compaction caused using chemical fertilizer.Improve
Soil physical and chemical property, strengthens soil water-retaining, fertilizer conservation, the ability of fertilizer.Beneficial microbe in alkaline land modifying agent enters soil
Form mutual symbiosis Relationship With Proliferation afterwards with Soil Microorganism, suppress harmful bacteria growing and be converted into beneficial bacterium, phase interaction
With, to mutually promote, play the synergy of colony, beneficial bacterium produces substantial amounts of metabolite during growth and breeding, promotes
The decomposition and inversion of organic matter, directly or indirectly can provide various nutrition and pungent for crop, promote and regulate and control crop life
It is long.Soil porosity, penetrating exchangeability and plant survival rate is improved, increases beneficial bacterium and edaphon.Meanwhile, in crop
The advantage profitable strain of root growth can suppress harmful pathogen procreation, strengthen the degeneration-resistant resistance against diseases of crop, reduce continuous cropping crop
Disease index, year after year apply can alleviate significantly continuous cropping obstacle.Environmental pollution is reduced, to people, animal, Environmental security, nontoxic, is one
Plant environment-friendly type fertilizer.
Alkaline land modifying agent is, according to rhizosphere soil microecology and plant battalion physiological principle, to be lived with multifunctional microbial
Property bacterium (nitrogen-fixing bacteria, phosphate solubilizing bacteria, B. mucilaginocus) be core, with fertilizer type organic matter as carrier, then be equipped with a small amount of inorganic support
Point and trace element process with pollution-free, nuisanceless, be suitable to produce the new-type fertilizer of pollution-free food.This new fertilizer
Material can draw to crop rhizosphere soils and be implanted with beneficial microorganism dominant group, reach infertile field strong sprout, growth-promoting to crops fertilizer again
Diseases prevention and the purpose of good quality and high output.According to the requirement of Ministry of Agriculture's alkaline land modifying agent professional standard (NY/T798-2004), effectively
Number of viable have to be larger than 2,000 ten thousand/gram, total nutrient (N+P2O5+K2O) and have to be larger than 6%.Ensure high number of viable,
The support material for accounting for product formula ratio 70%-80% is the principal element for affecting number of viable.Produce in the market saline and alkaline
Ground modifying agent product mainly has following problem：
1st, it is main by the use of turf or humic acid as organic carrier.Contain substantial amounts of organic matter, C/N in turf and humic acid
Than meeting the life condition of microorganism, the number of viable of microorganism is ensure that.But turf and humic acid belong to mineral matter, by state
The restriction of family's resource, a large amount of exploitations can destroy ecology, and apply in soil it is difficult to dissolve, organic matter therein and humic acid are very
Difficult to be affected fertilizer efficiency by crop utilization, while the price of turf and humic acid also goes up year by year, the production cost of product is also year by year
Improve.
2nd, product forms are mainly based on powdery.Drying due to containing viable bacteria in alkaline land modifying agent, in granulation process
Number of viable is had a great impact, and as turf and humic acid belong to mineral state Organic Ingredients, after granulation, is more difficult to dissolving,
Grain affects the quality and effect of product.But northern many place arable lands belong to machine sowing, and powder product cannot be used, so not particle
Change, directly influence using in a large number and promoting for product.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of life of the particle alkaline land modifying agent for not affecting biologically active
Product method, while providing a kind of new raw material for producing alkaline land modifying agent of safety and environmental protection, it is saline and alkaline that the method is produced
