Description
Technical field
The present invention relates to microbial manure technical field, specifically a kind of bio-feritlizer and its processing with water retaining function
Technique.
Background technique
Agricultural is the basic industry in China, always in occupation of important position in national economy, three China during the last ten years
Grain-production achieves significant growth.However, chemical fertilizer is excessively used for a long time and also brings ring while increasing grain yield
The problems such as border pollution, soil hardening, Soil degradation, ecological degeneration and quality of agricultural product decline.It is also made in addition, chemical fertilizer is excessively used
It being reduced at chemical fertilizer utilization ratio, agricultural cost is caused to increase, productivity effect reduces, and China's chemical fertilizer utilization ratio is 30% or so at present,
And the developed countries such as USA and Europe and Japan are generally 60% or more.
In ten big countermeasures of China's ecological environmental protection clearly advocate to promote " ecological agriculture ", preserve the ecological environment and
Agricultural land soil pushes the production of pollution-free healthy food, and guarantee has sufficient amount organic matter to return to soil, to promote the ecosystem
Middle biological cycle reaches holding and enhancing soil fertility and bioactivity purpose.Microbial bacterial agent can play prevent disease and
It is nontoxic to people and animals, it is the preferred means of production of high-quality Agricultural product without pollution.With the quick hair of China's modern agriculture
Exhibition, especially green organic agricultural cultivated area constantly expands, and specified microorganisms bacterium is dissolved into fertilizer, produces pair
The beneficial and full-featured fertilizer product of soil becomes the emphasis that current fertilizer production enterprise develops.
Microbial manure typically refers to a kind of particular product containing active microorganism bacterium, is applied in agricultural production, makees
Object can obtain fertilizer effect, and during the generation of this effect, the active microorganism bacterium that contains in product can will be in soil
The elements decomposition and inversions such as nitrogen, phosphorus, the potassium of certain for example invalid states of the nonabsorbable substance of crop have at what can directly be absorbed by crop
The nutriments such as nitrogen, phosphorus, the potassium of effect, and plant stimulatory material matter, antibiotics etc. are generated in its metabolic process, so as to improve work
Object nutrition condition reduces pest and disease damage, promotes crop robust growth, achieve the purpose that volume increase.There was only these in microbial manure
In the case that beneficial microbial bacteria is in vigorous breeding, metabolism, the conversion of substance and the formation ability of beneficial metabolites
Carry out, therefore, in microbial manure beneficial microorganism number of viable and vigorous vital movement be its validity basis and
Prerequisite.
Water is indispensable substance in microbial nutrition, it is not only a kind of nutriment or microbial cell
Primary chemical composition.Water is the good solvent of nutriment and metabolite, and nutriment and metabolite are all to pass through dissolution
Cell is entered and left with being dispersed in water.Water is the medium that various biochemical reactions are able to carry out in cell, and participates in many biochemistry
Reaction, so microorganism optimum is lived in a humid environment, in dry soil, microorganism can only be in the dormant state
Survival is maintained, this is also the microbial manure reason not good enough in arid area validity.
The method that the existing fertilizer with water-holding slow-release function largely uses physics to blend, is by high hydroscopic resin
It is directly mixed with the fertilizer such as microbial inoculum and nitrogen, phosphorus, potassium, a kind of high effect microorganism seed such as Patent No. 96120571.7 is raw
Long promotor, and application No. is 200710156464.1 multifunctional additive for greening seedling growth substrate.Above two fertilizer
Material is directly to mix high hydroscopic resin with microbial bacterial agent.Since high hydroscopic resin is granular solids, with microbial bacteria
Agent specific gravity is different, and water-absorbing resin itself has high-hydroscopicity energy, and the method that the two is directly admixed is difficult to be uniformly mixed, be unfavorable for
Microorganism growth, high hydroscopic resin are also difficult to play a role, and directly affect the using effect of fertilizer.
