Abstract
The production method of amino acid trac eelement chelated silicon fertilizer includes the following steps: utilizing waste protein and excess hydrochloric acid or sulfuric acid to make hydrolysis, and chelating trace element to form amino acid trace element chelate, then adding water quench dregs or yellow phosphorus dregs to make waste acid activate silicon fertilizer and make amino acid chelate and silicon fertilizer attain the optimum pH value and obtain optimum fertilizer efficiency. Said invented amino acid trace element silicon fertilizer features low cost and good yield-increasing effect.
Description
The present invention relates to amino-acid trace element chalted silicon fertilizer and production method thereof.
Siliceous fertilizer is continue N, P, the later the fourth-largest plant essential element of K, and China lacks the soil area of silicon above half according to investigations.Effect of increasing production to scarce silicon area siliceous fertilizer is very obvious.Patent announcement number is 88104650.Chinese patent, utilize Na
2SiO
3Be used for farm crop as efficient siliceous fertilizer, it is few to have a consumption, good effectiveness.But because Na
2SiO
3The production cost height fails big area to promote the use of.Patent announcement number 1056863. " production methods of siliceous fertilizer " utilize sandstone, Wingdale, coal and mineralizer to calcine through fragmentation, the levigate again siliceous fertilizer that forms.This siliceous fertilizer major ingredient is CaSiO
3,, be difficult to by plant absorbing because of water insoluble.Domestic most producer utilizes siliceous Water Quenching Slag, yellow phosphorus slag, flyash etc. as raw material, promptly uses as siliceous fertilizer after dried, crushed.But because silicon majority wherein is with CaSiO
3Exist, be difficult to be dissolved in water, the fertilizer efficiency effect is slow, and effect of increasing production is not obvious.Chinese patent application number be 991145371.2 inventions with Water Quenching Slag as amino acid whose neutralizing agent, make the amino-acid chelate of production reduced in and expense, effectively save production cost.But its objective is the production amino-acid chelate, is not to be purpose to produce siliceous fertilizer, and the Water Quenching Slag consumption is few.
The objective of the invention is to utilize the acidic solution behind the proteolysis, be used for the activation treatment that siliceous fertilizer is produced once more, reach the purpose of " one acid dual-purpose ".
When proteolysis, need with a large amount of strong acid (HCl, H
2SO
4) as catalyzer, after hydrolysis finishes, then will be with in a large amount of alkali and remove spent acid, add and micro-ly just can reach higher chelation percent.And deacidification needs to add a large amount of alkali, has not only increased cost, and produces unwanted inorganic salt of farm crop such as NaCl.The present invention is used to activate siliceous fertilizer with the spent acid of protein hydrolysate, both can save siliceous fertilizer with acid, can reduce neutralization alkali in the amino-acid chelate production process again, and real is " one acid dual-purpose kills two birds with one stone ".Bring the trace element fertilizer of chelating type simultaneously at the siliceous fertilizer activatory.Because the siliceous fertilizer ratio is big, this is as solid, and disintegration is a powder behind the Water Quenching Slag chance acid-respons, has reduced crushing process.The amino acid trace element chelated thing that generates with active silicon fertilizer as carrier and dispersion agent.
The present invention is realized by following technical scheme.
With various depleted protein is raw material, hydrochloric acid with 25～33% or 20～40% sulfuric acid are hydrolyzed, and the weight ratio of discarded albumen and strong acid is 1: 1.5～5 during hydrolysis, after hydrolysis finished, the oxide compound or the inorganic salt that add trace element carried out chelatropic reaction.The inorganic salt that add are to serve as according to calculating with amino acid whose content in the solution, and the mole number of the trace element of adding is 40～70% of an amino acid mole number.Because trace element chelation percent under acidic conditions is lower, so acid chelating liquid is sprayed into siliceous fertilizer bed blending disacidifies such as Water Quenching Slag, ageing 1～2 day is placed in the back that stirs, and is amino acid trace element chelated thing required for the present invention.
The invention has the advantages that:
1, the used acid of the present invention catalyzer that is protein hydrolysate is again the activator during siliceous fertilizer is produced, and has realized " one acid dual-purpose ", has saved cost greatly.
2, oven dry was a great problem during amino-acid trace element was produced, and conventional drying plant can't reach the oven dry purpose, adopt spray drying device can better solve dry problem, but expense was too high.The present invention adopts the siliceous fertilizer raw material not only to make neutralizing agent but also make sorbent material, and the amino-acid trace element chalted silicon fertilizer of generation is loose not to lump, and gets final product with the usual way oven dry, if granulation promptly can be dried after the first granulation, has simplified drying course, has saved drying plant.
3, amino acid trace element chelated thing is few as the base manure consumption, uses separately, and consumption is difficult to grasp, and adds to use homodisperse difficult in other fertilizer, and amino acid trace element chelated in addition thing is easy to the moisture absorption, to disperseing to bring bigger difficulty.The present invention is mixed with amino-acid chelate and siliceous fertilizer with spray pattern, mixed after wherein acid and siliceous fertilizer play priming reaction, make siliceous fertilizer both play the effect of neutralizing agent, play the good action of dispersion agent and carrier again.
4, Water Quenching Slag is a particulate state, after handling with amino acid trace element chelated liquid, is the fine powder material through the reaction disintegration, has reduced pulverizing, mechanical milling process, has saved expense.
5, the fertilizer of the present invention's production shows that through agricultural experiment its effect of increasing production not only is better than equivalent single amino acid trace element chelated fertilizer, and is higher than both stimulation ratio sums.Illustrate that amino acid trace element chelated thing and activation siliceous fertilizer have good synergy.
