Description
Technical field
The present invention relates to chemical fertilizer field, more particularly to a kind of side of crystallization legal system industrial monoammonium phosphate coproduction special fertilizer for potatoes
Method.
Background technology
Potato also known as potato.It is one of Chinese five big staple foods, nutritive value is high, adaptive faculty is strong, yield is big, is the whole world
The third-largest important cereal crops, are only second to wheat and corn.The bad ammonia inspection content of potato is higher, and the profit that is easily absorbed by the body
With fat content is one thousandth or so.The content of mineral substances of potato is one to two times higher than general cereal crop, phosphorous outstanding
It is abundant.In organic acid, most to contain citric acid, malic acid takes second place, next has oxalic acid, lactic acid etc..Potato is to contain vitamin
The very abundant crop of type and quantity, especially vitamin C, per hectogram fresh sweet potato, content is up to 20 to 40 milligrams.But mesh
It is preceding due to devoting exclusive attention to output simply, the application of a large amount of pesticides, chemical fertilizer causes soil hardening, salination getting worse, the utilization of fertilizer
Rate is not high.And crystallize legal system industrial monoammonium phosphate mother liquor with enter system circulation use, metal ion especially iron from
The enrichment of son can be entrained to product with crystallization entrainment metal ion, influence if mother liquor is not further processed
The color and purity of product.And the expense of mother liquid disposal is also relatively high.
Invention content
Soil texture, controlling plant diseases, raising utilization rate of fertilizer, volume increase can be improved the object of the present invention is to provide a kind of
Increase matter, the method for cheap crystallization legal system industrial monoammonium phosphate coproduction special fertilizer for potatoes.
In order to solve the above technical problems, the side of crystallization legal system industrial monoammonium phosphate coproduction special fertilizer for potatoes of the present invention
Method, after the acceptable industrial monoammonium phosphate slurry in industrial phosphoric acid and ammonia and obtained by concentration is crystallized successively, centrifugation, gained
Filter cake is industrial monoammonium phosphate finished product, and the mother liquor of gained is added in reaction kettle, and element needed for potato is added into reaction kettle
Mixture is stirred continuously and reaction kettle is heated to 55~65 DEG C by the heating rate of 2~3.5 DEG C/min, by the mixed of reaction kettle
Slurry is closed to send to spray drying tower drying, the water content 2.5~3% of gained special fertilizer for potatoes.
Further, in industrial phosphoric acid and ammonia and the pH of the acceptable industrial monoammonium phosphate slurry of concentration gained is 3~3.8.
Preferably, P in mother liquor2O5Mass content be 25~42%, N mass content be 4.2~8.3%, SO4 2-Matter
It is 0.3~1.2% to measure the mass content that content is 2.5~4.3%, Ca.
Preferably, the mixture that element needed for potato is added into the reaction kettle is urea：Potassium sulfate=1：1.6~
33~46 parts of 2.7 base manure, borax：Zinc sulfate=0.8~1.5：2.3 4~8 parts of mixture, decomposed plant organic fertilizer 30
~52 parts, 3~8 parts of phosphogypsum dihydrate, 4~10 parts of potassium fulvate.
Further, the decomposed plant organic fertilizer is straw：Rape cake：Dregs of beans=5~8：2.5：1.3 straw
The mixture of stalk, rape cake and dregs of beans, the mixture are mixed with water after crushed, are added after EM bacteria agent through stirring evenly, are sent out
Ferment 10~15 days.
Using above-mentioned technical proposal, because potato is tuber crops, likes loose soil, lead in technical scheme of the present invention
Cross and can be effectively increased soil organic colloid using decomposed plant organic fertilizer, soil particle is cemented to crumb structure, soil water-retaining,
Fertilizer conservation and good permeability, and can effectively adjust the soil moisture；Because potato is to like potassium crop, the source of potassium is in the technical program
Potassium sulfate and potassium fulvate, wherein potassium fulvate not only also chelate constant and trace nutrient supplemented with potassium resource makes it preferably
It is utilized for plant, controlling plant diseases, enhancing Flood resistance, excitation plant microbiological activity, slow release fertilizer promote plant to battalion
The absorption of element is supported, soil texture is improved；Phosphogypsum dihydrate is a kind of cheap soil conditioner, while being given birth to for phosphorus compound fertilizer
The waste ardealite of production producer headache solves outlet；Use the mother liquor of crystallization legal system industrial monoammonium phosphate for raw material one side
The expense for reducing mother liquid disposal optimizes the system environments of crystallization legal system industrial monoammonium phosphate, is that potato is special on the other hand
Cheap phosphorus, nitrogen and ferro element are provided with fertilizer.
The beneficial effects of the invention are as follows：Using technical solutions according to the invention, raw material is easy to get, is cheap, not only can
Improve soil texture, can also controlling plant diseases, improve utilization rate of fertilizer, increasing of quality and production crystallization legal system industrial monoammonium phosphate connection
The method for producing special fertilizer for potatoes.
Specific implementation mode
The present invention is described further with reference to embodiment：
