Description
Technical field
The invention belongs to novel organic fertilizer preparation fields, and in particular to a kind of eutrophy organic fertilizer for adding phosphorus potassium breeze
Preparation method.
Background technique
Organic fertilizer is the fertilizer based on carbon containing that plant and animal residues are passed through to fermentation maturity, and N-P-K content is generally
4-7%, for improving soil fertility, providing plant nutrient, raising crop quality.To meet crops nutrient demand, organic fertilizer
Usage amount is generally large.
Industrial crops are larger to the demand of N P and K, more than the supply of soil and organic fertilizer, thus often in organic fertilizer
Except apply nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, phosphorus potash fertilizer or its compound fertilizer, or direct application effective N P and K containing appropriate amount is organic
Compound fertilizer, wherein nitrogenous fertilizer is usually ammonium salt, urea, and choice is smaller.The phosphate fertilizer, potash fertilizer or phosphorus potash fertilizer, mixed organic manure
Contained available phosphorus potassium, no matter quick-acting or sustained release, long-acting, generally all by extracting or special processing, processing, use cost are usual
It is higher, wherein rapid available phosphorus potassium contained by quick-acting phosphate fertilizer, potash fertilizer, phosphorus potash fertilizer or mixed organic manure, if fertilizer leads to without appropriate preparation
It is often all easy to run off, utilization rate is lower, needs to apply every year and even apply repeatedly in 1 year.Also, in mixed organic manure effectively
The cost of phosphorus potassium usually accounts for the larger specific gravity of cost of material, often more than half, thus reduce available phosphorus potassium in organic fertilizer
Cost is an important technological problems of this field.
China possesses middle-low grade phosphorus abundant, potassium mineral aggregate resource, during producing high level phosphate fertilizer, potash fertilizer,
The procedure of processing by higher costs such as flotation, calcining, dissolutions is generally required, while generating large quantity of exhaust gas, waste water, needs to handle
Ability qualified discharge also generates a greater amount of tailings and needs to store up or fill, storage pad of the tailing in addition to occupying large area
Ground is also easy to generation environment pollution especially water pollution, and wherein there is also rainy season Dam Break Problems for tailing dam, while tailing is generally also
Containing some phosphorus or potassium, end can be utilized.
Thus, it in recent years, for ground phosphate rock, potassium breeze, develops controlled micro crystallization processing, be modified, and direct or compound is used as
The technology of fertilizer is reduced the crystallite dimension and its distribution of miberal powder by micronization, improves the specific surface area and activity of miberal powder, from
And the dissolution rate of phosphorus, potassium composition is improved, including instant, sustained release phosphorus, the dissolution rate of potassium composition and benefit during arable farming
With rate and fertilizer efficiency.The controlled micro crystallization processing, is a kind of new technology for developing and using mid low grade phosphate rock and insoluble potassium mine, mainly
It is that, crushing, ball milling the methods of broken by height are finally handled phosphorus ore, potassium mine to -200 mesh, or even -400 mesh.
Since phosphorus ore, the broken of potassium mine raw material, crushing, controlled micro crystallization processing, modified process flow are short, operation is easy, throwing
Money is few, mainly physical process, thus prepared controlled micro crystallization phosphate fertilizer, cost is relatively low for potash fertilizer, uses efficiency-cost ratio height.The technology pair
Phosphorus ore, the requirement of potassium mine raw material grade are lower, to the of less demanding of mineral aggregate sorting；To the utilization rate of powder raw material up to 100%, nothing
Tailing discharge.
In recent years, organic fertilizer research and the application for adding controlled micro crystallization ground phosphate rock are more, add the organic of controlled micro crystallization potassium breeze
Fertilizer research and application it is less, while add controlled micro crystallization ground phosphate rock, controlled micro crystallization potassium breeze organic fertilizer research and application it is more rare,
Reason is that the activation of potassium breeze and potassium dissolution are more much more difficult than ground phosphate rock.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of preparation side of eutrophy organic fertilizer for adding phosphorus potassium breeze
Method.The present invention makes phosphorus by bonding, embedding by the way that miberal powder crystallite to be activated to ground phosphate rock and potassium breeze ultra-fine grinding, and further
Organic matter is combined closely in potassium breeze, microorganism fungus kind and the organic matter that can ferment, fermentation, fermenting is made.
The present invention adds the preparation method of the eutrophy organic fertilizer of phosphorus potassium breeze, includes the following steps:
(1) thin by phosphorus ore material ultra-fine grinding to -200 mesh or more, it is by potassium mineral aggregate ultra-fine grinding to -600 mesh or thinner, then press quality
Be uniformly mixed than 1-10:5, or after phosphorus ore material, potassium mineral aggregate 0.5-10:5 in mass ratio are mixed common superfine microcrystal activate to-
600 mesh are thinner, obtain the phosphorus potassium mine superfine powder of crystallite activation；
(2) by the phosphorus potassium mine superfine powder addition 1-5m% in step (1) in attapulgite, starch, polyvinyl alcohol
It is one or more, and mix；
(3) mixture in step (2) is incorporated to organic matter in can ferment organic matter and/or fermentation by 1:2-5 dry ratio, is mixed
It is even, so that phosphorus potassium mine superfine powder is attached on organic particle surface or is buried and is overlying in organic particle；
(4) mixture water content in step (3) is adjusted to 40-60m%, fermented 15-60 days, dry to water content 30m% hereinafter,
Or granulating and drying is to water content 30m% hereinafter, the eutrophy organic fertilizer of addition phosphorus potassium breeze is made.
In step (1), when potassium mine used includes mainly or mainly the raw material of the higher hardness such as potassium feldspar, preferably by phosphorus
Mineral aggregate, potassium mineral aggregate carry out ultra-fine grinding respectively, wherein potassium mineral aggregate ultra-fine grinding to -1000 mesh (particle outer diameter all < 13 μm) or
It is thinner preferably, more preferably by potassium mineral aggregate ultra-fine grinding to -2000 mesh (particle outer diameter whole < 6.5 μm), phosphorus ore material ultra-fine grinding
To -400 mesh (particle outer diameter whole < 38 μm) or thinner preferably；Ground phosphate rock, potassium breeze after ultra-fine grinding, specific surface area
The preferred 0.1-0.5:1 of ratio, powder method for detecting specific area are air permeability method；Ground phosphate rock, potassium breeze after ultra-fine grinding press matter
Prepared organic fertilizer fertilizer efficiency is preferable when amount is than 1-2:5 ratio mixing.
It, can be by phosphorus ore material, potassium mineral aggregate when potassium mine used includes mainly or mainly the raw material of the higher hardness such as potassium feldspar
0.5-2:5 mixing and processing extremely -600 mesh in mass ratio, prepared organic fertilizer also can reach preferable fertilizer efficiency, wherein at mixture
Reason is more preferable to -1000 mesh.
When potassium mine used be mainly or it is main comprising containing muscovite etc. compared with soft raw material when, it is excellent in addition to crushing respectively
Choosing is with phosphorus ore co-grinding to -600 mesh or more carefully.
