Description
Technical field
The present invention relates to technical field of fertilizer production, specifically a kind of high concentration organic-inorganic compound fertilizer granulating agent.
Background technique
The organic fertilizer content of organic matter is high, and nutrient necessary to 16 kinds needed for crop is complete, is gone out with organic fertilizer production
Agricultural product it is full of nutrition best in quality, and crop anti-adversity is strong, is almost not necessarily to applying pesticides, but since nutrient is outstanding
It is that the N-P-K content that crop demand mostly and in soil lacks is very low, it is difficult to meet the needs of crop high yield.
Inorganic composite fertilizer N-P-K content is very high, and application ensuing crop yield significantly promotes or even double, but is free from
Organic matter, chronic administration, soil aggregate structure destroy, and ecological functions are degenerated, and crop anti-adversity is poor, easily sick, easy to be non-irrigated, easy to be flooded and easy
Early ageing, deterioration in quality are even very poor.
It will be apparent that the advantage and disadvantage complementarity of organic fertilizer and inorganic composite fertilizer is very strong, raw material and the production of organic fertilizer will be produced
The organic-inorganic compound fertilizer that the raw material mixture manufacturing of inorganic composite fertilizer goes out, can will meet simultaneously crop high-quality high yield
It needs, the fact is also such.
But the organic materials of organic fertilizer and inorganic material its attribute of production inorganic composite fertilizer are produced completely on the contrary, two
Person is combined together the difficult of granulation, and is that nitrogen, phosphorus, potassium and the content of organic matter are higher, and the difficulty of granulation is bigger.This is just
It is that last century the nineties agricultural technology circle and Minister Agriculture of China just advocate development organic-inorganic compound fertilizer, and have even to this day
Machine inorganic complex fertilizer is also without the basic reason as main fertilizer, that is, third generation mainstream fertilizer.
Summary of the invention
When above-mentioned existing production compound organic and inorganic fertilizer, nitrogen, phosphorus, potassium and the content of organic matter are higher, and the difficulty of granulation is got over
Greatly.
The purpose of the present invention is to provide a kind of high concentration organic-inorganic compound fertilizer granulating agents, according to parts by weight, institute
State granulating agent include 2-9 parts of six meta-acid sodium phosphate, 1-8 parts of potassium fulvate.
In the technical solution of the application, six meta-acid sodium phosphates are white powder crystal, are a kind of important industrial chemicals, easily
It is dissolved in water, there is very strong hygroscopicity, and generates viscosity after moisture absorption, in 150-480 DEG C of high temperature, viscosity is increased, and is a kind of
High-temperature adhesives, hardening by cooling are shunk, and the organic materials and inorganic material of high concentration organic-inorganic compound fertilizer can will be produced
It is tightly bonded together, form dense granule: six meta-acid sodium phosphates are a kind of polymer of molecular weight larger (611.17), can be with
Microelement forms soluble complexes in calcium, magnesium, iron, manganese, zinc etc., itself is also the very high a large amount of members of phosphorus pentoxide content
Attainment point.
The potassium fulvate is that had by agriculture and forestry organic waste materials such as stalk, sawdust, sugar residues through the macromolecule that microbial fermentation is formed
Machine object is also biochemical fulvic acid potassium.Its content of organic matter 67% or so, nitrogenous 2-4%, 11-13% containing potassium oxide, phosphorous 1%
Left and right, potassium fulvate is the powdery organic matter of 100-200 mesh, soluble easily in water, has very strong hygroscopicity, wet at 50 DEG C or more
There is larger viscosity under thermal environment, granulating can be bonded with the organic materials and inorganic material of production organic-inorganic compound fertilizer,
Lower than 40 DEG C and it is following when curing shrinkage.
Six meta-acid sodium phosphates are inorganic compounds, and bonding granulating plays a role larger under damp and hot high temperature (180 DEG C) environment,
And potassium fulvate is a kind of uncertain organic compound of component, bonds granulating under damp and hot lower temperature (50-80 DEG C) environment
It plays a role larger.That is, potassium fulvate larger, and six meta-acid in dryer that is bonded into granule effect in pelletizer
The effect that sodium phosphate is bonded into big grain is larger.
Six meta-acid sodium phosphates are both high-efficiency binder, and a kind of very high inorganic complexing of phosphorus pentoxide containing inorganic nutrients
Agent, and potassium fulvate is both high-efficiency binder, and one kind contains the very high organic complexing agent of organic matter.Both materials,
Middle microelements of calcium, magnesium, iron, manganese, zinc etc. in organic materials can be complexed under hygrothermal environment, form stable water-soluble complex
Object strengthens the argillification of its granulating, increases its particle rounding, consolidation, intensity, moreover it is possible to provide inorganic nutrients or organic feeding
Point, increase the effect of the content of inorganic nutrients N P and K and organic matter.Granulating agent is done with both materials, npk nutrient can be made
Total content reaches 40-50%, and the content of organic matter reaches 15-25%, when solving above-mentioned existing production compound organic and inorganic fertilizer,
Nitrogen, phosphorus, potassium and the content of organic matter are higher, the bigger defect of the difficulty of granulation.
Preferably, according to parts by weight, the granulating agent include 4-7 parts of six meta-acid sodium phosphate, 3-6 parts of potassium fulvate.
More preferably, according to parts by weight, the granulating agent includes 5.5 parts of six meta-acid sodium phosphate, potassium fulvate 5.5
Part.

Preferably, the granulating agent accounts for the 12% of high concentration organic-inorganic compound fertilizer total raw material weight ratio.
Preferably, the six meta-acids sodium phosphate is containing P2O5>=68% powder crystal.
Preferably, the fulvic acid is that acquirement is made containing K in biomass ferment2O mass fraction is 10-14%, mass containing N point
Number is the biochemical fulvic acid of 2-4%.
Preferably, the potassium fulvate is fine-powdered, and mesh number is 100-200 mesh.
More preferably, the mesh number of the potassium fulvate is 150 mesh.
Preferably, the application method of the granulating agent: by the six meta-acids sodium phosphate and the potassium fulvate by above-mentioned heavy
It measures number to be uniformly mixed, be then added by the 10-15% for accounting for high concentration organic-inorganic compound fertilizer total raw material weight ratio, mixing is equal
Granulating agent is added after even to be granulated, and screening process is carried out to its product, granularity rejected product carries out crushing to again return to again making
In grain machine, after qualified products drying and naturally cool to after room temperature up to high concentration organic-inorganic compound fertilizer.
Preferably, the six meta-acids sodium phosphate and the potassium fulvate account for high concentration organic and inorganic compound by above-mentioned parts by weight
The 10-15% of complex fertilizer material total raw material weight ratio is separately added into, and granulating agent is added after mixing and is granulated, and sieves to its product
Divide processing, granularity rejected product crush again and again returned in pelletizer, after qualified products drying and is naturally cooled to normal
Up to high concentration organic-inorganic compound fertilizer after temperature.Granulation process is using conventional prilling.
Six meta-acid sodium phosphates and potassium fulvate are uniformly mixed by above-mentioned parts by weight, then by accounting for organic-inorganic compound fertilizer
Total material 10-15% weight ratio is added, and enters pelletizer after mixing and is granulated, or six meta-acid sodium phosphates and potassium fulvate are pressed
It is metered by the 10-15% difference for accounting for organic-inorganic compound fertilizer, enter pelletizer after mixing and be granulated, it is produced later
