Problems solved by technology

[0006] The technical problem mainly solved by the present invention is aimed at the defects that currently common amino acid chelated fertilizers are mostly produced by acid-base hydrolysis, the equipment is complicated, the cost is expensive, and the fertilizer efficiency is low due to the chelation of a single amino acid and a single trace element. A method of using ginger and buffalo milk to provide trace elements, extracting compound amino acids from discarded fish bones and fish viscera, and performing chelation reaction under slightly acidic conditions to finally obtain fertilizers
The amino acid chelate in the fertilizer prepared by the invention is rich in types, which effectively solves the defect of single component of traditional amino acid micro-fertilizers, and has high fertilizer efficiency, which is 3 to 4 times that of ordinary amino acid micro-fertilizers, and has broad application prospects

example 1

[0021] Take fresh ginger and grind it in a mortar, wrap it with gauze and squeeze out the juice, collect the ginger juice, then take the buffalo milk and pour it into a pot to boil, when it is cooled to 80°C, pour the hot water milk into the In ginger juice, stir evenly, seal with plastic wrap, let it stand for 5 minutes until it solidifies to get the compound trace element milk jelly, and set aside; collect discarded fish bones and fish viscera, first mix fish bones and water at a mass ratio of 1:10 Afterwards, simmer for 3 hours, filter and remove the fish bones to obtain fish bone soup, then rinse the collected fish viscera with deionized water for 3 times and then chop to obtain minced fish. The mass ratio of minced fish and pomelo peel is 10:1 After mixing, knead into balls and repeatedly beat 200 times to obtain hair gel fish balls; immerse the above hair gel fish balls in fish bone soup according to the mass ratio of 1:10, simmer for 4 hours, filter and remove the filter...

example 2

[0024]Take fresh ginger and grind it in a mortar, wrap it with gauze and squeeze out the juice, collect the ginger juice, then take buffalo milk and pour it into a pot to boil, when it cools down to 81°C, pour hot water milk into In ginger juice, stir evenly, seal with plastic wrap, and let it stand for 6 minutes until it solidifies to get the compound trace element milk jelly, which is ready for use; collect discarded fish bones and fish viscera, first mix fish bones and water at a mass ratio of 1:10 Then simmer for 4 hours, filter and remove the fish bones to obtain fish bone soup, then rinse the collected fish viscera with deionized water for 4 times and chop to obtain minced fish. The mass ratio of minced fish and pomelo peel is 10:1 After mixing, knead into balls and repeatedly beat 230 times to obtain hair gel fish balls; immerse the above hair gel fish balls in the fish bone soup according to the mass ratio of 1:10, simmer for 5 hours, filter and remove the filter residu...

example 3

[0027] Take fresh ginger and grind it in a mortar, wrap it with gauze and squeeze out the juice, collect the ginger juice, then take buffalo milk and pour it into a pot to boil, when it is cooled to 82°C, pour the hot water milk into the In ginger juice, stir evenly, seal with plastic wrap, let it stand for 8 minutes until it solidifies to get the compound trace element milk jelly, and set aside; collect discarded fish bones and fish viscera, first mix fish bones and water at a mass ratio of 1:10 Afterwards, simmer slowly for 5 hours, filter and remove the fish bones to obtain fish bone soup, then rinse the collected fish viscera with deionized water for 5 times and chop to obtain minced fish, and mix the minced fish and grapefruit peel in a mass ratio of 10:1 After mixing, knead into balls and repeatedly beat 250 times to obtain hair gel fish balls; according to the mass ratio of 1:10, immerse the above hair gel fish balls in fish bone soup, simmer for 6 hours, filter and remo...

Abstract

The invention relates to a preparation method of a composite amino acid chelated trace element fertilizer and belongs to the technical field of fertilizer preparation. Ginger protease in ginger juice and casein in high-butterfat-content buffalo milk are subjected to reaction at high temperature to be solidified within short time to obtain frozen milk rich in trace elements such as iron, zinc and calcium, soup is made with fish bones, fish viscera are beaten to be colloidal, the fishbone soup is stewed slowly, various kinds of amino acid are infiltrated and blended mutually under the thermal drive, centrifugation is conducted to obtain composite amino acid extracting liquid, and the composite amino acid and the trace elements are chelated, so that the charge of the complex ion in the fertilizer tends to be neutral, the fertilizer can reach to the roots of crops quickly by avoiding cation exchange in soil and is easy to absorb, and the fertilizer efficiency is improved. The amino acid chelate in the fertilizer prepared by the method has rich varieties, so the defect that the traditional amino acid micro-element fertilizer has single component is effectively solved; the fertilizer has high fertilizer efficiency which is 3 to 4 times that of the common amino acid micro-element fertilizer, and has wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of a compound amino acid chelated trace element fertilizer, which belongs to the technical field of fertilizer preparation. Background technique [0002] At present, the trace element fertilizers used in my country are mostly inorganic sulfates and chlorides. After these fertilizers are applied to the soil alone or mixed with other fertilizers, the nutrients will often be fixed or degraded into insoluble salts, resulting in low or even complete utilization of micro-fertilizers. invalidated. Even if some trace elements such as ferrous iron are sprayed on the leaves, they will be quickly oxidized to high-valent iron, which is difficult to meet the needs of crop growth. [0003] The fertilizer efficiency of chelated micro-fertilizers is 2 to 5 times that of inorganic micro-fertilizers. In recent years, foreign countries have mostly used EDTA, HEDTA, etc. as chelating agents to produce chelated micro-fertilize...
