Abstract
The invention discloses a powdery phosphorus fertilizer as well as a preparation method and a using method thereof. The preparation method is characterized by comprising the following steps: uniformly mixing magnesium ammonium phosphate, an easily-soluble phosphorus fertilizer and an acidifier; and grinding and screening the mixture, so that the granularity of the screened materials is smaller than 150 meshes. The screened powdery fertilizer coats seeds or other granulated fertilizers. Compared with the prior art, the powdery phosphorus fertilizer has the advantages that the applied range of magnesium ammonium phosphate is expanded, and the fertilizer applying efficiency of the magnesium ammonium phosphate is improved.
Description
Technical field
The present invention relates to a kind of powdery phosphate fertilizer and preparation method and using method, belong to chemical fertilizer manufacture, soil agrochemistry field.
Background technology
First, by magnesium ammonium phosphate slow-release fertilizer phosphorous, nitrogenous, that contain the waste water reclamation such as magnesium, conventionally with powdery form, sell and use.In the use procedure of powdered acid ammonium magnesium, dust is large, but also have cannot machine fertilising, cannot with the problem such as other fertilizer blending.It is not high that this causes the magnesium ammonium phosphate of recovery to be worth, and even because find no market, and become with magnesium ammonium phosphate sediment method, processes phosphorous, nitrogenous, to contain the waste water treatment plant of the waste water such as magnesium burden.
Secondly, magnesium ammonium phosphate is a kind of slow release fertilizer, and it is insoluble in water, so can not burn root.In addition,, even if rain in torrents, magnesium ammonium phosphate can not outflow with water as traditional processable nitrogenous fertilizer, phosphate fertilizer yet.This loss not only significant wastage nitrogenous fertilizer, phosphate fertilizer, and the nitrogen phosphoric running off caused widespread pollution from the overuse of fertilizers and pesticides in rural area, is one of arch-criminal who causes freshwater lake eutrophication.
On the other hand, magnesium ammonium phosphate can slowly be dissolved by the organic acid of plant root exudation (citric acid, matrimony vine acid, oxalic acid etc.).In whole breeding time, plant all can secrete organic acid by root system, and in the time of vegetative growth phase and reproductive stage, secretory volume is especially many.And plant needs the stage of nutrient in a large number, be mainly also to nourish and grow and two stages of reproductive growth, so dissolve in organic acid solubility in citric acid fertilizer, can provide nutrient for plant.
Comprehensive above 2 known, after applied once magnesium ammonium phosphate, nutrient seldom runs off, and can provide the time of infertility from germinateing to yielding positive results required nitrogen, phosphorus, magnesium nutrient for crop.
Finally, the fertilizer efficiency of magnesium ammonium phosphate is between 3-8 month, and fertilizer efficiency is long, but after in being manured into soil, may occur in a short time the problem of fertilizer deficiency.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is for a kind of powdery phosphate fertilizer and preparation method and using method are provided.The method on seed and other other granulated fertilizers, expands the range of application of magnesium ammonium phosphate by parcel powdered acid ammonium magnesium.
Realizing object of the present invention can be by taking following technical scheme to reach:
A kind of powdery phosphate fertilizer, each components based on weight percentage, it is characterized in that: powdery phosphate fertilizer is mixed by magnesium ammonium phosphate, processable phosphate fertilizer, souring agent, obtain mixture, wherein magnesium ammonium phosphate 51-92%, processable phosphate fertilizer 5-41%, souring agent account for the 2-8% of mixture total weight amount, grind and sieve mixture, make the raw meal particle size after screening be less than 150 orders, obtain powdery phosphate fertilizer.
A preparation method for powdery phosphate fertilizer, each components based on weight percentage, is characterized in that comprising the steps:
A, magnesium ammonium phosphate, processable phosphate fertilizer, souring agent are mixed, obtain mixture, wherein magnesium ammonium phosphate 51-92%, processable phosphate fertilizer 5-41%, souring agent account for the 2-8% of mixture total weight amount;
B, grinding are also sieved mixture, make the raw meal particle size after screening be less than 150 orders, obtain powdery phosphate fertilizer.
In step a, described magnesium ammonium phosphate is six water magnesium ammonium phosphates or a water magnesium ammonium phosphate.
In step a, described processable phosphate fertilizer is calcium superphosphate, double superhosphate, monoammonium phosphate or diammonium phosphate.
In step a, souring agent is that one or two or more kinds in sulphur, ammonium sulfate, ammonium chloride, brown coal, gibberic acid, citric acid, Sodium Pyrosulfite, oxysuccinic acid, oxalic acid, succsinic acid, acetic acid, butyric acid, formic acid, valeric acid, lactic acid, pyruvic acid, propanedioic acid, tetronic acid, fumaric acid, amino acid is by the mixture of any ratio.
In step a, add as required the dispersion agent that accounts for processable phosphate fertilizer weight 0.01-30%, dispersion agent is methylene radical benzyl sodium naphthalene sulfonate or sodium methylene bis-naphthalene sulfonate.
In step a, add as required the hydrophober that accounts for processable phosphate fertilizer weight 0-10%, hydrophober is stearic acid or sodium stearate.
In step a, add as required the crystalline substance control agent that accounts for processable phosphate fertilizer weight 0-4%, brilliant control agent is benzyl naphthalene sodium sulfonate, sodium dibutyl naphthalene sulfonate, two butyric acid di-sec-octyl sodium sulfonate or methyl sodiosul foaliphatates.
A using method for powdery phosphate fertilizer, is wrapped in above-mentioned powdery phosphate fertilizer on seed or other granulated fertilizers.
Powdery phosphate fertilizer accounts for the 0.1-2.0% of seed or other granulated fertilizer gross weights.
Add as required the parcel promotor of the 0-25% that accounts for powdery phosphate fertilizer gross weight, parcel promotor is vegetables oil, resin or wax.
Beneficial effect of the present invention is:
The present invention, by magnesium ammonium phosphate is mixed with processable phosphate fertilizer, has solved the problem of using initial stage phosphoric undersupply.
The present invention, by magnesium ammonium phosphate is mixed with souring agent, reaches simulating plant root system secretion organic acid effect.Seed is grown into ripe plant, be through through sprouting stage and seedling stage, but these two stage plant secretion organic acid scarce capacities, so a little less than absorbing energy the force rate maturation plant of nutrient.Add appropriate organic acid, on the one hand can activate the nutritive element in powdery phosphate fertilizer, on the other hand can activating soil in original nutritive element, thereby can improve the absorbed dose of nutrient.
The present invention, by adding anti-caking agent (comprising dispersion agent, hydrophober, brilliant control agent) prevention powdery phosphate fertilizer caking, improves service efficiency.
The present invention wraps up by interpolation that promotor has guaranteed can not separate out in parcel and cargo transport process or the problem such as precipitation, improves service efficiency.
In sum, the technology of the present invention compared with prior art, has expanded the range of application of magnesium ammonium phosphate, has improved the fertilising efficiency of magnesium ammonium phosphate.
