Abstract
The present invention relates to a preparation method of foliage fertilizer. It is made up by mixing quickly-acting azophoska, humic acid and amino acid mixture powder, cation EDTA complex microfertilizer and anion trace elements. Said invention provides its formula composition and its preparation method, and adopts gelatin alkaline hydrolysis method to prevente the amino acids from repolymerizing when it is dewatered, and adopts the mixing process of amino acid and human acid to form film and drying process, so that it can obtain obvious yield-increasing effect.
Description
Technical field
The present invention relates to the agricultural fertilizer manufacturing, specifically relate to a kind of preparation method of agricultural foliage fertilizer.
Background technology
Foliage fertilizer is a kind of new-type fertilizer, sprays foliage fertilizer and have the increase crop yield on farm crop, improves quality of agricultural product, reduces the chemical fertilizer usage quantity, and the enhancing farm crop are cold-resistant, the effects such as ability of drought resisting.Existing foliage fertilizer mainly is divided into four big classes: 1, multielement micro-fertilizer; 2, the little fertilizer of amino acid; 3, macroelement nitrogen phosphorus potassium adds trace element; 4, humic acid fertilizer.The each have their own effect of this four classes fertilizer, everybody wants this four classes fertilizer is combined in a kind of foliage fertilizer.But because phosphate radical PO
4 3-All can not stably coexist as with in a kind of solution with humic acids with divalent cationic microgel fertilizer (Zn, Mn, Fe, Cu), so up to now, and the practice report of the foliage fertilizer that rolls into one of no-trump trace element, quick-acting nitrogen phosphorus potassium, amino acid, humic acids.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, and a kind of preparation method who integrates the foliage fertilizer of trace element, quick-acting nitrogen phosphorus potassium, amino acid, humic acids is provided.
The objective of the invention is to realize by following measure:
The preparation method of foliage fertilizer, be to be quick-acting nitrogen phosphorus potassium the 60-65% of gross weight, humic acids and amino acid mixing powder account for the 15-20% of gross weight, positively charged ion EDTA complexing zinc fertilizer, EDTA complex copper fertilizer, EDTA complexing iron fertilizer, EDTA complexing manganese fertilizer sum and negatively charged ion trace element boric acid and ammonium molybdate sum, the two summation is the 15-20% of gross weight, stirs after the mixing, after ball mill is handled, 90% reaches 60 orders, is foliage fertilizer;
Humic acids and the preparation of amino acid mixing powder, be that gelatin is dissolved in the 80-100 ℃ of hot water, add KOH, heat 80-100 ℃ of alkaline hydrolysis, stirred 15-30 minute, gelatin: KOH: water weight ratio is 100: 5-7: 400-500, take out supernatant liquid, with the common film drying of humic acids pressed powder, amino acid solution: the humic acids weight ratio is 100: 200-300;
The preparation of the little fertilizer of EDTA complexing:
1. EDTA complexing zinc fertilizer
EDTA is water-soluble, and add KOH and zinc oxide, EDTA: KOH: ZnO: water is heavy
Amount is than being 100: 30-35: 20-25: 400-500, pH be at 4.5-5.5, supernatant liquid
Spraying drying;
2. EDTA complex copper fertilizer
EDTA is water-soluble, add KOH and CuO, temperature 80-100 ℃, stirred 1 hour, EDTA: KOH: ZnO: water weight ratio is 100: 30-35: 15-20: 400-500, pH be at 4.5-5.5, the supernatant liquid spraying drying;
3. EDTA complexing iron fertilizer
EDTA is water-soluble, add KOH and FeSO
47H
2O stirs EDTA: KOH: FeSO
47H
2O: water weight ratio is 100: 30-35: 40-45: 400-500, pH be at 4.5-5.5, the supernatant liquid spraying drying;
4. EDTA complexing manganese fertilizer
EDTA is water-soluble, add KOH and MnCO
3, temperature 80-100 ℃, stirred EDTA: KOH: MnCO 1 hour
3: water weight ratio is 100: 30-35: 25-30: 400-500, pH be at 4.5-5.5, the supernatant liquid spraying drying;
Positively charged ion EDTA complexing zinc fertilizer, EDTA complex copper fertilizer, EDTA complexing iron fertilizer, EDTA complexing manganese fertilizer sum: negatively charged ion boric acid, ammonium molybdate sum raw material usage ratio are 4-8: 1, in positively charged ion EDTA complexing zinc fertilizer, EDTA complex copper fertilizer, EDTA complexing iron fertilizer, EDTA complexing manganese fertilizer, the little fertilizer of complexing more than two kinds is arranged, and usage ratio is random;
Quick-acting nitrogen phosphorus potassium are the raw materials more than three kinds in Tripotassium phosphate, monoammonium phosphate, diammonium phosphate, four kinds of raw materials of urea, and usage ratio is random.
Raw material:
Quick-acting nitrogen phosphorus potassium: commercially available industrial first grade comprises Tripotassium phosphate, monoammonium phosphate, diammonium phosphate, urea;
Gelatin; Be meant and contain the industrial first grade of aminoacids complex more than 80%.
EDTA: ethylenediamine tetraacetic acid (EDTA);
Foliage fertilizer product index: nitrogen phosphorus potassium 〉=50%, trace element 〉=2%, amino acid 〉=3%, humic acids 〉=8%.
The present invention has following advantage compared to existing technology: the present invention adopts the positively charged ion way of complex protection in advance; through positively charged ion zinc; copper; iron; manganese forms EDTA zinc with the EDTA complexing respectively; EDTA copper; EDTA iron; EDTA manganese; just can avoid reacting with phosphate radical and humic acids; having solved phosphate radical and humic acids all can not stably coexist as with in a kind of solution with divalent cationic microgel fertilizer; simultaneously; amino acid of the present invention adopts gelatin alkaline hydrolysis method; amino acid regroups when avoiding dewatering; take to mix with the humic acids pressed powder; carry out common film drying, the foliage fertilizer that makes surpasses the standard of Ministry of Agriculture's regulation solid foliage fertilizer: nitrogen phosphorus potassium (N+P
