Abstract

The invention discloses a crude amino acid fertilizer and a preparation method thereof. The crude amino acid fertilizer is prepared from raw materials in parts by weight as follows: 20-30 parts of poultry feather, 10-15 parts of human and livestock hair, 20-35 parts of kaolin, 70-100 parts of a 50% sulfuric acid solution, 20-30 parts of sodium bicarbonate, 30-50 parts of crop straw, 5-10 parts of limestone powder, 12-17 parts of trace elements, 12-15 parts of urea, 10-15 parts of ammonium dihydrogen phosphate, 14-20 parts of potassium nitrate, 4-5 parts of a binder and a required amount of water. Specifically, poultry feather as well as human and livestock hair is soaked with the sulfuric acid solution to obtain a crude amino acid solution, then the trace elements and nutrient elements including N, P and K are added for chelation, a product after chelation and a homogenate of the crop straw are mixed with kaolin, and finally, the granular fertilizer is prepared; waste is recycled, environmental pollution is prevented, and meanwhile, a small amount of amino acid is generated but has obvious action effects including slow release and adjustment of nutrient element absorption.

Description

A kind of crude amino acid fertilizer and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to a kind of crude amino acid fertilizer and preparation method thereof.

Background technology

The effect of amino acid in plant growth: 1, the Source Of Supply of organonitrogen nutrient, forms and repairs crop body tissue; 2, the sequestrant of metal ion, amino acid has the effect of complexation of metal ions, easily the moderate-element needed for crop and trace element (calcium, magnesium, iron, manganese, zinc, copper, molybdenum, boron, selenium etc.) are carried in plant materials, improve crop to the utilization ratio of various nutrient; (3) effect of endogenous hormones is had, adjustable plant-growth; (4) amino acid is promotor and the catalyzer of making the various enzyme of synthesis in object, to the metabolism of crop, promotes that plant growth plays an important role; (5) amino acid can strengthen the photosynthesis of crop; (6) be containing amino and carboxyl in the middle of amino acid whose molecule, crop inner salt soda balance can be regulated; (7) amino acid is physiologically active substance, has extremely important physiological function, can strengthen the anti-adversity of crop.

Amino acid fertilizer utilizes animal wool, skin, hoof tips, people's hair wastes and agriculture, pair, the proteinaceous tankage of fishery to generate kilnitamin through hydrolysis or fermentable, then with the inorganic nutrients chelating such as trace element or the fertilizer that mixes.Showing that its ecological benefits, economic benefit are all very remarkable through the application for many years on each crop of south China and the north, is a kind of well new-type fertilizer.

Fertilizer efficiency is good: according to test statistics result, and multiple amino acids mixes, its fertilizer efficiency higher than etc. the single amino acid of nitrogen quantity, also higher than etc. the inorganic nitrogenous fertilizer of nitrogen quantity, a large amount of amino acid improves the utilization ratio of nutrient with its synergistic effect.

Fertilizer efficiency block: the amino acid in amino acid fertilizer directly can be absorbed by the organ of crop, and (inorganic fertilizer, fertilizer need degraded, in photosynthesis Passive intake or osmotic absorption), use the later stage to see positive effect, crop jujube tree can be promoted simultaneously, shorten growth cycle.

Improve quality of agricultural product: amino acid fertilizer is amino acid and admixtion and amino acid complex etc. mainly, and organism accounts for certain proportion, thus can improve quality of agricultural product.As grain protein matter content increases; Cotton fiber is long, and quality is good;

Improve the ecological environment: execute fertilizer noresidue in the ground, soil physico-chemical property can be improved, improve preserve moisture and fertility and permeability.

Metabolic function strengthens, and resistance improves: strengthening crop physiology function is that stem stalk is sturdy, blade thickness, and leaf area expands, and chlorophyll increases, and functional period extends; Because photosynthesis improves, Dry matter formation and accumulation are accelerated, and crop can cross premature ripening, and also because the own vitality of crop strengthens, drought resisting, hot-dry wind tolerance, disease and insect resistance, lodging resistance improve, thus realize high and stable yields.
