Abstract
The compounded fertilizer is produced through dissolving chitin in water solution of glacial acetic acid at 85 deg.c, adding hydrogen peroxide to degrade for 5 hr, filtering and adding amino acids, zinc sulfate, magnesium sulfate and boric acid in certain weight proportion to obtain the compounded fertilizer. It contains chitosan oligomer in 0.001-30 wt%, amino nitrogen in 0.01-20 wt%, Zn, B and Mg in 0.001-20 wt% and amino acids in 0.1-60 wt%. The present invention has the advantages of obvious resistance raising effect, obvious plant growth promoting effect, combined fertilizer and pesticide effects and capacity of improving crop quality.
Description
Technical field
The present invention relates to a kind of preparation method of composite fertilizer.
Background technology
Chitin oligosaccharide is a kind of small molecules, and is water-soluble, can be absorbed by human body, animal, plant body, and inhibiting rates such as the common bacteriosis of plant, mildew are reached more than 90%, makes plant play the egodefense effect, suppresses growth of pathogenic bacteria; Can also promote the activation of vegetable cell, the stimulating plant growth does not have so far with the fertilizer of chitin oligosaccharide as substrate.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of preparation method of composite fertilizer is provided.
Technical scheme of the present invention is: a kind of preparation method of composite fertilizer is characterized in that: chitin or chitosan are dissolved temperature control with acid, the molecular chain that adds hydrogen peroxide or enzyme brisement chitin or chitin, degraded 0.5-12 hour, and filtered, add amino acid, zinc sulfate, sal epsom, boric acid.
The present invention has the following advantages: disease-resistant, degeneration-resistant, the promotes growth effect is remarkable, reaches combination of pesticide and fertilizer, can improve the resistance against diseases of plant, improves crop quality, promote plant-growth.
Embodiment
Embodiment: a kind of preparation method of composite fertilizer, with 10 kilograms of chitins, with the glacial acetic acid aqueous solution dissolving of 200 kilogram 2% (concentration expressed in percentage by weight, down together), stir, temperature is controlled at 85 ℃, adds 4 kilogram 30% hydrogen peroxide oxidation, degrades 5 hours, filter, add 6 kilograms of amino acid, 5 kilo sulfuric acid zinc, 4 kilo sulfuric acid magnesium, 8 kilograms of boric acid, get finished product, chitin is respectively 10 with the part by weight of acid and hydrogen peroxide: 1-8: 0.1-8; The weight ratio scope of chitin and amino acid, zinc sulfate, magnesium nitrate and boric acid respectively is 10: 1-10: 1-10: 1-10: 1-15; Chitin oligosaccharide content 0.001-30% (concentration expressed in percentage by weight, down together); The content of amino nitrogen is 0.01-20%; The total amount of zinc, boron, magnesium is 0.001-20%; Amino acid 0.1-60%.
Claims (1)
1, a kind of preparation method of composite fertilizer is characterized in that: chitin or chitosan dissolved with acid, and temperature control, the molecular chain of adding hydrogen peroxide or enzyme brisement chitin or chitin was degraded 0.5-12 hour, filtered, and added amino acid, zinc sulfate, sal epsom, boric acid.
