Abstract
The invention provides the pelletizing additives of a kind of nitrogen, phosphorus, potassium compound fertilizer, its composition comprises the powder shape alpha-semi water plaster stone (CaSO of common blending
41/2H
2O) and the powder shape inhale the ammonia inorganics, inhaling the ammonia inorganics is to select one or more arbitrarily from wilkinite, zeolite powder, sepiolite and diatomite.Its proportioning is: alpha-semi water plaster stone: 40～60% (weight), inhale the ammonia inorganics: 60～40% (weight).The particulate state made through extruder grain of blending is multiple fertile mutually for this pelletizing additives and powder shape bicarbonate of ammonia, phosphoric acid salt and Repone K, has that bicarbonate of ammonia is difficult for decomposing, caking; Nitrogen, phosphorus, potassium content proportioning are fit to the plant-growth needs, advantages such as nutrient length time of releasing.
Description
The present invention relates to a kind of pelletizing additives for remixed fertilizer.
A kind of magnesium ammonium phosphate (MgNH of 2% that is used to be not less than is disclosed in English Patent 896,284
4PO
4) or secondary magnesium phosphate (MgHPO
4) as additive, add the method that bicarbonate of ammonia improves the anti-caking of bicarbonate of ammonia and reduces the bicarbonate of ammonia natural decomposition.Bicarbonate of ammonia is meeting natural decomposition ammonification, carbonic acid gas and water: NH in air
4HCO
3→ NH
3+ CO
2+ H
2O.Valuable nitrogen has been lost in this decomposition, and ammonia makes the transporter unhappy, and moisture content easily makes the bicarbonate of ammonia caking.The secondary magnesium phosphate and the ammonia react that add generate six water magnesium ammonium phosphate (MgNH
4PO
46H
2O), absorb bicarbonate of ammonia and decomposed the NH that emits
3And H
2O.The bicarbonate of ammonia particle surface can be suppressed to decompose by one deck magnesium ammonium phosphate parcel, and particle is freely rolled, and can not lump.But this method does not satisfy agricultural to be gone up granular nitrogen, phosphorus, the multiple fertile needs of potassium.The magnesium oxide powder, monoammonium phosphate that disclose the common blending of a kind of usefulness in Chinese patent 85100516 are as additive, add the method that evenly is blended into nitrogen, phosphorus, the multiple fertilizer of potassium ternary in bicarbonate of ammonia and the Repone K, this method is to generate magnesium ammonium phosphate six hydrates: MgO+NH with magnesium oxide and monoammonium phosphate
4H
2PO
4+ 5H
2O → MgNH
4PO
46H
2The free-water that O, bicarbonate of ammonia decomposite becomes crystal water and is fixed in the magnesium ammonium phosphate double salt, and the double salt of generation is wrapped in the ammonium bicarbonate crystal surface, suppresses bicarbonate of ammonia and decomposes.But magnesium ammonium phosphate six hydrates solubleness in water and diluted acid that this method generates very little (" phosphate fertilizer and multiple fertilizer " magazine 1989 the 3rd phase the 12nd page) sees the following form:
25 ℃, dissolving gram number in the 100ml solution
Therefore, solubility P in the multiple fertilizer that makes of this method
2O
5Content less, do not reach solubility P in the multiple fertilizer of nitrogen, phosphorus, potassium of national Specification
2O
5The requirement of content 〉=40% has influenced the absorption of plant phosphate fertilizer.In addition, this multiple fertilizer is powdery, fails to satisfy agricultural and goes up the multiple fertile needs of particulate state.
The purpose of this invention is to provide the pelletizing additives for remixed fertilizer that a kind of suitable agricultural, gardening are used, this pelletizing additives and powder shape bicarbonate of ammonia, phosphoric acid salt and the Repone K multiple fertilizer of particulate state made through extruder grain of blending mutually have that bicarbonate of ammonia is difficult for decomposing, caking in air; Nitrogen, phosphorus, potassium content proportioning are fit to the plant needs, and fertilising is convenient, advantages such as nutrient length time of releasing.
The present invention is achieved in that this pelletizing additives for remixed fertilizer composition comprises the powder shape alpha-semi water plaster stone (CaSO of common blending
41/2 H
2O) and the powder shape inhale the ammonia inorganics, inhaling the ammonia inorganics is to select one or more arbitrarily from wilkinite, zeolite powder, sepiolite and diatomite.Consisting of of this pelletizing additives: alpha-semi water plaster stone: 40～60%(weight), inhale the ammonia inorganics: 60～40%(weight).Inhaling ammonia inorganics the best is wilkinite, zeolite powder.When suction ammonia inorganics was wilkinite, this pelletizing additives consisted of: alpha-semi water plaster stone: 40～60%(weight), and wilkinite: 60～40%(weight).When suction ammonia inorganics was zeolite powder, this was made feed additives and consists of: alpha-semi water plaster stone: 40～60%(weight), and zeolite powder: 40～60%(weight).When suction ammonia inorganics was sepiolite, this pelletizing additives consisted of: alpha-semi water plaster stone: 40～60%(weight), and sepiolite: 60～40%(weight).When suction ammonia inorganics was diatomite, this pelletizing additives consisted of: α-half water cream: 40～60%(weight), and diatomite: 60～40%(weight).The powder particle diameter of the powder shape alpha-semi water plaster stone of this pelletizing additives and suction ammonia inorganics is 60～100 microns.This pelletizing additives and powder shape bicarbonate of ammonia, phosphoric acid salt and Repone K blending mutually; make compounded fertilizer of granulated through the Squeezinggranulator extruder grain; it consists of: pelletizing additives: 2～15%(weight); bicarbonate of ammonia: 50～72%(weight), phosphoric acid salt and Repone K: 13～44%(weight).The particle diameter of the compound fertilizer of making through the Squeezinggranulator extruder grain is 2.5～8 millimeters.
Principle of the present invention is: one of unsettled important factor of bicarbonate of ammonia is to contain free-water, has only free-water is removed, and could improve its stability.By alpha-semi water plaster stone (CaSO
41/2 H
2O) and inhale the pelletizing additives that the ammonia inorganics forms and have cellular cavity structure, its specific surface area reaches 500 meters
2More than/the gram, the surface has very big adsorptive power, thereby water and ammonia are had the intensive absorption property, and free-water and ammonia in the bicarbonate of ammonia are adsorbed.Thereby improved the multiple fertile stability of bicarbonate of ammonia.
In addition, pelletizing additives of the present invention and water generate the double salt of band crystal water, have reduced free water content in the multiple fertilizer, have also improved the multiple fertile stability of bicarbonate of ammonia.
Pelletizing additives of the present invention and ammonium bicarbonate complex mixed fertilizer material after the ageing cooling, form harder solid bridge through the Squeezinggranulator extruder grain in the particle, multiple fertile surface-area reduces greatly, has reduced the volatilization of ammonia-state nitrogen.Also increased the stability of bicarbonate of ammonia granular compound fertilizer.
The double salt of the brilliant water of the band that pelletizing additives of the present invention and water generate can not influence the solubility P in monoammonium phosphate or the diammonium phosphate
2O
5Content.
The present invention has overcome bicarbonate of ammonia easily decomposition in air in the prior art, and the magnesium ammonium phosphate six hydrates solubleness in water that generates in the powdered modified multiple fertilizer is less, does not reach solubility P
2O
5The defective of 〉=40% national standard.
Nitrogen in the multiple fertilizer of the granulated ammonium bicarbonate that this pelletizing additives for remixed fertilizer is made, phosphorus, potassium content can be mixed with various special-purpose fertile by the needs of farm crop fertilising, and purposes is wider.
Now the invention will be further described in conjunction with the embodiments.
