Embodiment 1
[0034] An amino acid concentrated liquid fertilizer, including the formula of the following components:
[0035] Protein powder water solution 3500kg,
[0036] Enzyme bacteria 100kg,
[0037] 25kg brown sugar,
[0038] Urea 500kg,
[0039] Potassium sulfate 200kg,
[0040] Monoammonium phosphate 300kg.
[0041] In the amino acid concentrated liquid fertilizer, the mass percentage concentration of the protein powder water solution is 3.5%. The total nutrient (N+P2O5+K2O) in the amino acid concentrate liquid fertilizer is ≥15%. The amino acid in the amino acid concentrate liquid fertilizer is ≥5%. The humic acid in the amino acid concentrate liquid fertilizer is ≥3%. The total number of beneficial viable humic acid bacteria in the amino acid concentrated liquid fertilizer is ≥7×107 / ml.
[0042] A preparation method of amino acid concentrated liquid fertilizer includes the following steps:
[0043] a. Add enzyme bacteria and brown sugar to the protein powder water with a concentration of 3...
Embodiment 2
[0048] An amino acid concentrated liquid fertilizer, including the formula of the following components:
[0049] Protein powder water solution 3500kg,
[0050] Enzyme bacteria 100kg,
[0051] 25kg brown sugar,
[0052] Urea 500kg,
[0053] Potassium sulfate 200kg,
[0054] Monoammonium phosphate 300kg.
[0055] A preparation method of amino acid concentrated liquid fertilizer includes the following steps:
[0056] a. Add enzyme bacteria and brown sugar to the 3.5% protein powder water solution and mix well;
[0057] b. Ferment for 8 days, stir 3 times a day, add potassium sulfate and monoammonium phosphate and stir evenly, ferment for another 9 days, stir 2 times a day;
[0058] c. Add urea and stir evenly, filter to obtain concentrated amino acid liquid fertilizer.
[0059] In step c, when no fermented foam appears in the mixed liquor, add urea water boiled with boiling water and cooled to normal temperature and stir evenly. The mass ratio of urea to water is 3:10.

[0066] Potassium sulfate 200kg,
[0067] Monoammonium phosphate 300kg.
[0068] A preparation method of amino acid concentrated liquid fertilizer includes the following steps:
[0069] a. Add enzyme bacteria and brown sugar to the 3.5% protein powder water solution and mix well;
[0070] b. Fermentation for 6 days, stirring 2 times a day, then adding potassium sulfate and monoammonium phosphate and stirring evenly, then fermenting for another 10 days, stirring 2 times a day;
[0071] c. Add urea and stir evenly, filter to obtain concentrated amino acid liquid fertilizer.
[0072] In step c, when no fermented foam appears in the mixed liquor, add urea water boiled with boiling water and cooled to normal temperature and stir evenly. The mass ratio of urea to water i...
