Embodiment 1

[0027] An amino acid organic liquid fertilizer comprises the following components in parts by weight: 90 parts of chicken feathers, 4 parts of glucose, 4 parts of biogas slurry, 15 parts of macroelements, 1 part of microelements and 1 part of chelating agent.

[0028] Among them, the macroelement is a mixture of urea and potassium dihydrogen phosphate in a weight ratio of 1:2; the trace element is copper sulfate; the chelating agent is ethylenediaminetetraacetic acid.

[0029] Biogas slurry is prepared by the following method: chicken manure and water are mixed in a weight ratio of 3:1, added to a biogas digester, then fermented at 37°C for 15 days, filtered, and the filter residue is removed. The obtained filtrate is biogas slurry.

[0030] The preparation method of above-mentioned amino acid organic liquid fertilizer, comprises the following steps:

[0031] (1) adding glucose into the biogas slurry, mixing evenly, and fermenting in a closed container at a fermentation temper...

[0036] Among them, the macroelement is a mixture of urea and potassium dihydrogen phosphate in a weight ratio of 1:2; the trace element is zinc sulfate; and the chelating agent is ethylenediamine di-o-phenylacetic acid.

[0037] The biogas slurry is prepared by the following method: mix chicken manure and water at a weight ratio of 5:2, add it to a biogas digester, then ferment at 30°C for 15 days, filter, and remove the filter residue, and the obtained filtrate is biogas slurry.

[0038] The preparation method of above-mentioned amino acid organic liquid fertilizer, comprises the following steps:

[0039] (1) adding glucose into the biogas slurry, mixing evenly, and sealing the fermentation at a fermentation temperatu...

Embodiment 3

[0043] An amino acid organic liquid fertilizer comprises the following components in parts by weight: 110 parts of chicken feathers, 6 parts of glucose, 6 parts of biogas slurry, 20 parts of macroelements, 1 part of microelements and 1 part of chelating agent.

[0044] Among them, the macroelement is a mixture of urea and potassium dihydrogen phosphate in a weight ratio of 1:2; the trace element is ferrous sulfate; and the chelating agent is ethylenediaminetetraacetic acid.

[0045] The biogas slurry is prepared by the following method: mix chicken manure and water at a weight ratio of 5:2, add it to a biogas digester, then ferment at 40°C for 10 days, filter, and remove the filter residue, and the obtained filtrate is biogas slurry.

[0046] The preparation method of above-mentioned amino acid organic liquid fertilizer, comprises the following steps:

[0047] (1) adding glucose into the biogas slurry, mixing evenly, and sealing the fermentation at a fermentation temperature o...

Abstract

The invention discloses amino acid organic liquid fertilizer and a preparation method thereof. The amino acid organic liquid fertilizer is prepared from the following components in parts by weight: 90to 110 parts of poultry feather, 4 to 6 parts of glucose, 4 to 6 parts of biogas slurry, 15 to 20 parts of macro elements, 1 to 5 parts of trace elements and 0.8 to 1.5 parts of chelating agent. Thepreparation method comprises the following steps: adding the glucose into the biogas slurry, fermenting in a closed manner to obtain a fermented solution; then adding the poultry feather into the fermented solution, fermenting in a closed manner to prepare an amino acid solution, then adding the chelating agent, macro elements and trace elements into the amino acid solution to react, finally cooling to the room temperature, thus obtaining the amino acid organic liquid fertilizer. The amino acid organic fertilizer is prepared by adopting microorganisms to ferment the poultry feather. By adopting the preparation method, no racemization effect is produced, the environment is not polluted, the production cost is low, the obtained amino acid is high in biological activity and low in content oftoxic and harmful articles; and meanwhile, the amino acid organic liquid fertilizer provided by the invention is easier to absorb by crops, so that the resource waste can be reduced.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to an amino acid organic liquid fertilizer and a preparation method thereof. Background technique [0002] my country is a big agricultural country, and the use of chemical fertilizers ushered in a new round of growth in my country's crop production. At the same time, the negative effects of chemical fertilizers are increasingly being discovered. The abuse of chemical fertilizers and unreasonable application methods are becoming more and more serious. In recent years, the input of chemical fertilizers in my country is not directly proportional to the output of production, resulting in waste of resources and extremely serious pollution. Taking nitrogen as an example, the loss rate of nitrogen in my country is as high as 40% and is increasing year by year. Most of the excess nitrogen exists in different soil layers in the form of nitrate and nitrite, which po...
