Abstract
A compound silicon fertilizer particularly containing soluble silicic acid and silica gel is prepared by the reaction of water-quenched slags or molten glass compound from blast furnace with sulfuric acid tog enerate a matter containing soluble silicic acid, silica gel, calcium salt, magnesium salt and aluminium salt and mixing it with agricultural fertilizer, and features low cost, more nutrients necessary for plant, quick taking its action and loosening soil.
Description
The invention belongs to silicon composite fertilizer and production method thereof, particularly contain composite fertilizer of mensuration dissolubility silicic and silica gel and preparation method thereof.
At present, though China's widespread production and use compound manure, great majority all are only nitrogenous, phosphorus, potassium, and the nutrient that contained plant needs is complete inadequately.In recent years, a large amount of research and facts have proved, silicon, calcium, magnesium elements also are the key elements of plant-growth, therefore China has the fertilizer that some areas are brought into use siliceous fertilizer and contained silico-calcium magnesium, but these fertilizer all belong to late effect property fertilizer, and its fertilizer efficiency is quite slow, and it is higher that cost seems relatively, and can make the hardening soil, therefore be difficult for popularizing.
The purpose of this invention is to provide a kind of silicon composite fertilizer and production method thereof, its technology is simple, and cost is lower, contains elements such as soluble silicon, calcium, magnesium, aluminium and nitrogen, phosphorus, potassium, and nutrition is more complete.
Technical scheme of the present invention is as follows:
The raw material that this silicon composite fertilizer adopts is the blast furnace water quenching slag of metal smelting or the resultant and the farming fertilizer of melten glass body fertilizer and sulfuric acid reaction, contain 5～20% mensuration dissolubility silicic and silica gel (SiO2.nH2O) in the composite fertilizer that mixes, 2～12% soluble calcium salt (CaSO4.2H2O), 1～10% solubility magnesium salts (MgSO4.7H2O), 1～5% aluminum soluble salt (Al2 (SO4) 3.xH2O).Mix the agricultural fertilizer that adds and to adopt the fertilizer that is rich in nitrogen, phosphorus, potassium, as urea, ammonium nitrate, vitriolate of tartar, Repone K, phosphorus ammonium and organism.
The processing step of producing this silicon composite fertilizer is: (1) gets the blast furnace water quenching slag or the melten glass body fertilizer of metal smelting, and is with its oven dry, levigate to 80～100 orders; (2) in the complex acid groove vitriol oil (d=1.84) is slowly injected water, prepare required concentration (50～90%), take advantage of heat to stir with slag and carry out chemical reaction, the consumption of slag calculates with the basicity of its detection; (3) resultant of reaction is stacked ageing 7～10 days, the check free acid according to the adaptation situation of farm crop to pH value, neutralizes with alkaline fertilizer; (4) according to the needs of farm crop, in mixing tank, add farming fertilizer, trace element and plant-growth regulator, mix, molding, granulating, packing.
In the reaction process that makes sulfuric acid and slag, should on the calculating consumption basis that sulfuric acid participates in reacting fully, add 0.2～0.5%, so that make chemical reaction complete.After the reaction of sulfuric acid and slag, the agricultural fertilizer that mixes add nitrogenous, phosphorus, potassium can adopt urea, ammonium nitrate, vitriolate of tartar, Repone K, phosphorus ammonium and organism.When being prepared into compoiste fertilizer if add organism, organism should be earlier and slag mix while and sulfuric acid reaction.
The blast furnace water quenching slag of metal smelting is generally passed into disuse, or be utilized to prepare cement, price is quite cheap, wherein be rich in a large amount of water-fast SiO2, CaO, MgO, Al2O3, after adding sulfuric acid, can be converted into soluble SiO2.nH2O, CaSO4.2H2O, CaSO4.1/2H2O, MgSO4.7H2O, Al2 (SO4) 3.xH2O etc. contains the compound of crystal water, thereby become the available nutrient of solubility, be equipped with nitrogenous again, phosphorus, the fertilizer of potassium and other trace element and plant-growth regulator, it is comprehensive just can to become contained composition, obvious results composite fertilizer.Wherein element silicon can play the support cell walls, prevents paddy rice generation rice blast and damping-off, prevents the plant lodging, increases the effect of output; Calcium constituent is the important element that forms cell walls, can prevent the lodging of plant, makes plant seed full, increases output; The magnesium elements plant generates the indispensable element of chlorophyll, and the chlorophyll abundance can help the absorption of nutritive substances such as nitrogen, phosphorus, potassium, prevents the albinism of plant.
Complex acid process the vitriol oil slowly being injected water can produce heat, and the sulfuric acid after the dilution can produce heat again when reacting with slag, and fierce thermopositive reaction meeting produces evaporation, therefore should add into some dilute sulphuric acids than calculating consumption.Because the generation of evaporation and crystal water compound, moisture contained in the product that finally obtains is not many, thus do not need to be dried processing, thus can reduce equipment, simplify technology, further reduce cost.
In sum, the present invention can make full use of cheap water granulated slag, with better simply technology and less equipment, prepare the composite fertilizer of containing more soluble silicon, calcium, magnesium, aluminium element, make the nutrition in the fertilizer comprehensive, it is very fast to use fertilizer efficiency, and product cost is lower, has simultaneously also opened up another wide approach except that manufacturing cement for the blast furnace water quenching slag.
Below, according to several specific embodiments of the present invention, it is further described.
Embodiment 1: the tealeaves composite fertilizer special
(1) it is levigate to 100 purpose water granulated slags to get 450～650Kg, and its oven dry is stand-by; (2) in the complex acid groove, the vitriol oil of 125 liters of d=1.84 is slowly injected 180Kg water, be made into dilute sulphuric acid, take advantage of heat to stir and carry out chemical reaction with slag; (3) resultant of reaction is stacked ageing 7～10 days, the check free acid is neutralized to PH=5～6 with the alkaline fertilizer fused(calcium magnesium)phosphate, obtains work in-process; (4) mix in following ratio and agricultural fertilizer and trace element in mixing tank, 488Kg work in-process, 237Kg urea, 125Kg monoammonium phosphate, 120Kg vitriolate of tartar and 30Kg contain the trace element of zinc, boron, copper, rare earth, last molding, granulating, packing.
