Description
Technical field
The present invention relates to ammonium polyphosphate chelate fertilizer of the cash crop such as a kind of melon beans, fruit tree and preparation method thereof.
Background technology
Ammonium polyphosphate is a kind of poly-phosphate containing N and P, by its polymerization degree can be divided into oligomeric, in poly-and high poly-3 kinds, its polymerization degree more highly water-soluble is less, otherwise then water-soluble larger.Can be divided into crystallization shape and amorphous by its structure, crystal form ammonium polyphosphate is long-chain shape water-insoluble salt.The general molecular formula of ammonium polyphosphate is (NH
4)
(n+2)p
no
(3n+1), when n is 10-20, for water-soluble; When n is greater than 20, it is insoluble.
Early 1970s, the U.S. develops with commodity phosphoric acid by wet process (54%P
2o
5, massfraction) and produce ammonium polyphosphate basal liquid fertilizer.China not yet has the enterprise of professional production ammonium polyphosphate fertilizer at present, its proterties, composition and production method remain in dispute, it is generally acknowledged as fertilizer ammonium polyphosphate it should is that short chain is entirely water-soluble, comprise the multiple ammonium polyphosphates such as ammonium phosphate, tripolyphosphate ammonium and four ammonium polyphosphates, the ammonium polyphosphate that the polymerization degree is higher, chain is longer only has a small amount of existence; Separately have data introduction, the agricultural ammonium polyphosphate polymerization degree is generally 5-18, and solvability is good, is the principal item of liquid fertilizer.Agricultural ammonium polyphosphate only has to survive on a small quantity in China and does not form commodity selling.
In the report about ammonium polyphosphate chelate fertilizer, mention in CN 102584488 A and prepare micro-element liquid chelating fertilizer with polypeptide-ammonium polyphosphate, but wherein ammonium polyphosphate is used to provide nitrogenous source, phosphorus source, do not serve as sequestrant, in addition, trace element is EDTA form, and this form is also not easy absorbed by crops, and cost is also higher; Also have in some patents, the polymerization degree of ammonium polyphosphate is not high, and does not meet water miscible requirement, and stable not.
Summary of the invention
The present invention is directed to above deficiency, provide a kind of ammonium polyphosphate chelate fertilizer and simple method for preparing, this fertilizer technique is simple, proportioning science, be applicable to very much foliage-spray and the fertigation of the crops such as watermelon, cowpea, granulated sugar tangerine, tangerine orange, banana, also can add in macroelement fertilizer as solid and liquid dosage form.
The present invention seeks to be achieved through the following technical solutions:
A kind of ammonium polyphosphate chelate fertilizer, the weight part of each raw material is:
Preferably, in described ammonium polyphosphate, the mass percent of N is greater than 24%, P
2o
5mass percent be greater than 45%, the polymerization degree is greater than 10.
Preferably, described ammonium polyphosphate is greater than 40g/100mL the solubleness of 25 DEG C.
Preferably, nitrocalcite is four water-calcium nitrate, and zinc sulfate is Zinc Sulphate Heptahydrate
Another object of the present invention is, provides the preparation method of described a kind of ammonium polyphosphate chelate fertilizer, comprises the steps:
(1) add ammonium polyphosphate according to formula, after being dissolved in water, add nitric acid adjust ph to 5.5-6.0, temperature controls at 60 DEG C ~ 70 DEG C;
(2) add nitrocalcite, magnesium sulfate, manganous sulfate, zinc sulfate and ferrous sulfate successively, temperature controls at 40 DEG C ~ 50 DEG C, stirs 20-30min;
(3) after reaction terminating, add dehydrated alcohol, inner complex is separated out, dry, obtain solid ammonium polyphosphate inner complex;
(4) solid ammonium polyphosphate inner complex is mixed with ammonium molybdate, boric acid and saltpetre, obtain the finished product.
Described formula is:
Preferably, described drying is 100 DEG C ~ 120 DEG C vacuum-dryings.
Present invention also offers the described application of a kind of ammonium polyphosphate chelate fertilizer in the foliage-spray and fertigation of crop.
Present invention also offers the application in macroelement fertilizer as solid or fluid additive of described a kind of ammonium polyphosphate chelate fertilizer.
Reaction principle: in the present invention, water-soluble poly ammonium phosphate molecular formula is:
NH is hydrolyzed in acid (nitric acid) environment
3h
2o and polyphosphoric acid, and in polyphosphoric acid molecule-PO
3h-functional group can provide lone electron pair to metal ion, thus and Ca
2+, Mg
2+, Zn
2+, Mn
2+, Fe
2+form ligand inner complex;
Key problem in technology of the present invention is also it must is add nitrocalcite, magnesium sulfate, manganous sulfate, zinc sulfate and ferrous sulfate successively, this is because the ability of each adsorption of metal ions lone electron pair has dividing, with Ca of power
2+, Mg
2+, Mn
2+, Zn
2+, Fe
2+order strengthen successively; By controlling addition sequence, by magnetic agitation, suspension can be made to become clear soln; Simultaneous temperature controls at 40 DEG C ~ 50 DEG C, facilitates each metal ion and forms ligand inner complex, improve medium trace element stability, be more conducive to Crop.
The advantage that the present invention has relative to prior art and beneficial effect.
(1) ammonium polyphosphate (polymerization degree is greater than 10) related in the present invention is entirely water-soluble, and the inner complex of formation can be fully water-soluble.
(2) by controlling addition sequence, the chelate fertilizer in the present invention is stablized, and for zinc element, chelation percent is 79.8%, 30 days rate of fall-off be 3.3%, 180 days rate of fall-off is 5.8%; Meanwhile, make energy consumption low, chelatropic reaction can be realized at lesser temps; During Fertilizer application, convenient and swift molten water is fast, and nutrient collocation is rationally, obviously remarkably productive than the EDTA chelate fertilizer of same nutrient.The N of nitre state is provided while nitre acid for adjusting pH.
(3) sequestrant of domestic current use is mostly organic compound, and mainly based on EDTA, sugar alcohol, amino acid, xanthohumic acid, only a few uses mineral compound and polymkeric substance; Ammonium polyphosphate is a kind of inorganic polymer fertilizer inherently, and for crop provides nitrogenous source, phosphorus source, chelating cost is low, and technical process is simple.
