Description
Technical field
The present invention relates to the preparation technology of the water soluble fertilizer of a kind of chelating amino acids calcium and magnesium, belong to fertilizer process technology neck
Territory.
Background technology
At present, China market circulation water-soluble fertilizer mainly have: a great number of elements water-soluble fertilizer, trace element water-soluble fertilizer,
Containing aminoacid water-soluble fertilizer, containing humic acid water-soluble fertilizer, potassium dihydrogen phosphate, microbiology class water-soluble fertilizer, also there is few part tool
There is the product of specific function.
Many include referring to be dissolved completely in water containing 6 series products water soluble fertilizers before including humic acid water-soluble fertilizer
Elements compounding type fertilizer, compared with the kinds such as traditional calcium superphosphate, granulated compound fertilizer, water soluble fertilizer has the most excellent
Gesture.Being mainly characterized by consumption few, easy to use, use cost is low, and Crop is fast, and nutritional labeling utilization rate is high.Water solublity
Fertilizer is a kind of quick action fertilizer, can be dissolved completely in water, directly can be absorbed by the root system of crop and blade face, uses
Liquid manure is with executing, fertile with water band, and its effective absorbance exceeds common chemical fertilizer more than one times, and fertilizer efficiency is fast, it is possible to resolve high-yield crop is quick
The nutritional need of trophophase.
Traditional compound fertilizer easily causes fertilizer loss, body eutrophication, destruction Soil structure.And Water soluble fertilizer is as novel
Environment-friendly type fertilizer, it is to avoid the shortcoming that conventional composite is fertile, and Water soluble fertilizer is easy to use, can spray, rush and execute, and knot can be filled with spray drop
Close and use, can water with soil, allow plant root comprehensive engagement to fertilizer；Can be entered by blade face pore plant with foliage-spray
Inside thing, improve fertilizer absorption rate；Can also drip irrigation and soilless culture, save irrigation water and also raise labour efficiency and improve
Utilization rate of fertilizer.Water soluble fertilizer also has the advantage not available for conventional composite fertilizer, i.e. can improve crop quality, the life of minimizing crop
Reason disease.
Prior art exist problem: 1) part fertilizer be use each raw material is prepared respectively after, be dried, finally mix
Arriving, the uniformity that technical problem is that mixing brought is bad, and using effect and exterior quality are the best；2) chelated microelement and
The elements such as calcium, magnesium, potassium use EDTA and chelate, and edta salt dissolubility in cold water is the best, during use, uses water dissolution
After concentration of fertilizer inconsistent, affect using effect, and chelating be abundant not, raw material availability is the highest.
Publication No. CN103467159B, entitled " a kind of Chelating state composite fertilizer with trace elements and preparation method thereof "
Patent of invention, the technical scheme of this patent is i.e. to chelate various trace elements by EDTA, i.e. there is the equal of aforesaid mixing
The even problem that property is bad and dissolubility is bad, it addition, the chelation percent of EDTA is not high enough, exist for trace element with alkalescence
After fertilizer-responsive, precipitation, in use, the problem of meeting plug nozzle occur.
And for example Publication No. CN102964175B, entitled " a kind of Composite amino-acid-containinwater-soluble water-soluble fertilizer and preparation side thereof
Method " patent of invention, the chelating of the program is carried out at normal temperatures, and chelation percent is not high enough, and raw material availability is the highest, and the time is relatively
Long, be not suitable for large-scale production.
Summary of the invention
Present invention seek to address that in prior art, the water solublity of fertilizer is bad, and because chelating is insufficient, in the process of use
Middle generation is precipitated, the technical problem of plug nozzle, it is provided that the preparation work of the water soluble fertilizer of a kind of new chelating amino acids calcium and magnesium
Skill, by improvement and specifically raw material and the setting of formula of processing step so that the dissolubility of fertilizer is good, and does not exist stifled
The technical problem of plug nozzle.
In order to realize foregoing invention purpose, technical scheme is as follows:
A kind of preparation technology of the water soluble fertilizer of chelating amino acids calcium and magnesium, it is characterised in that: comprise the following steps:
A. calcium is chelated
Adding aminoacids complex 300～500 parts and water 800～1200 parts in reactor, temperature controls at 70～80 DEG C, stirring
After 1～2h, after regulation pH to 8～9, continue stirring；
B. chelated magnesium
In the solution that step A obtains, add magnesium sulfate 150～300 parts, continue stirring 1～2h；
C. post processing
Reactant liquor step B obtained is concentrated, cool down, obtain after drying the water solublity fertilizer of described chelating amino acids calcium and magnesium
Material.
In order to the present invention is better achieved, in step A, described aminoacids complex is by fur, the compound ammonia of leather class hydrolysis
Base acid.
In step A, the reagent used by described regulation pH value is potassium hydroxide.
In step A, after described regulation pH to 8～9, at 70～80 DEG C, stir 30～45min.
In step B, the temperature of chelated magnesium is 85～95 DEG C.
In step C, described concentration refers to that it is 60～70% that reactant liquor is concentrated into concentration.
In step C, described dry mode is for being spray-dried；The moisture of dried fertilizer is less than 5%.
In the water soluble fertilizer of described chelating amino acids calcium and magnesium: calcium content >=7.0%, content of magnesium >=3.0%, aminoacid contains
Amount >=30.0%.
Beneficial effects of the present invention:
(1) with background technology, the patent of invention of Publication No. CN103467159B is compared, and the present invention uses compounded amino
Acid chelates calcium, magnesium ion, chelates compared to EDTA, and chelating amino acids is more stable；With in background technology
CN102964175B compares, and chelation percent improves 5～10%, and the chelating time is shorter；
In technique, mixing in the liquid state after chelating, then be dried, the uniformity of mixing is good, and fertilization effect and exterior quality are equal
Obtain effective raising；It addition, the dissolubility after product adds water is good, do not have the technical problem of density unevenness.
(2) utilize aminoacid to chelate calcium and magnesium except the good stability of chelating, moreover it is possible to make the nutritional labeling of fertilizer more
Abundant, amino can improve the activity of enzyme in crop body, promotes carbohydrate-modifying, photosynthesis and protein synthesis, carries
High crop yield, chlorophyll content in leaf blades, strengthen crop cold resistance very salt tolerant, disease-resistant, degeneration-resistant ability, make crop health raw
Long.
(3) in the water soluble fertilizer that the technique of the present invention prepares, calcium content >=7.0%, content of magnesium >=3.0%, aminoacid
Content >=30.0%.The main calcium-magnesium-containing of fertilizer of the present invention and aminoacid, according to crop needs, can make with other fertilizer
With, more convenient to use, flexible, compared to the fertilizer of chelating plurality of inorganic salt, specific aim is higher, and the utilization rate of fertilizer is more
High.
(4), in step A of the present invention, regulation reagent used by pH value is preferably potassium hydroxide, while regulation pH value, supplements
Potassium element, increases the fertilizer efficiency of fertilizer.
