Embodiment 1

[0037] A method for fermenting low-value marine fish to produce amino acid foliar fertilizer includes the following steps:

[0038] a) Pulping: The low-value sea fish is cut into pieces after its head is removed, and water of 1 times its weight is added, and then it is pulped to obtain low-value sea fish paste;

[0039] b) Sterilization: Sterilize the low-value sea fish paste with chlorine gas while stirring at a low speed of 4 rpm; the amount of chlorine in the low-value sea fish paste during sterilization is 100 mg / L;

[0040] c) Removal of odor: heat the sterilized low-value marine fish paste at 70°C for 50 minutes, stir at 4 rpm during heating, and then filter out the water to obtain low-value marine fish dry matter, and use water to remove the low-value marine fish dry matter Wash 5 times, and then add water that is twice the weight of the dry matter of low-value marine fish to prepare low-value marine fish treatment slurry; after preparing the low-value marine fish treatment sl...

Embodiment 2

[0051] A method for fermenting low-value marine fish to produce amino acid foliar fertilizer includes the following steps:

[0052] a) Pulping: The low-value sea fish is cut into pieces after its head is removed, and 2 times the weight of water is added, then pulping, to make low-value sea fish paste;

[0053] b) Sterilization: Sterilize the low-value sea fish paste with chlorine gas while stirring at a low speed of 5 rpm; during the sterilization process, the amount of chlorine in the low-value sea fish paste is 120 mg / L;

[0054] c) Removal of odor: heat the sterilized low-value marine fish paste at 5°C for 60 minutes, stir at a low speed of 5 rpm during heating, and then filter out the water to obtain low-value marine fish dry matter. Wash 6 times, and then add water twice the weight of the low-value marine fish dry matter to prepare low-value marine fish treatment slurry; after preparing the low-value marine fish treatment slurry, adjust the pH value of the low-value marine fish ...

Embodiment 3

[0065] A method for fermenting low-value marine fish to produce amino acid foliar fertilizer includes the following steps:

[0066] a) Pulping: The low-value marine fish is cut into pieces after its head is removed, and 4 times the weight of water is added, followed by pulping to obtain low-value marine fish paste;

[0067] b) Sterilization: Sterilize the low-value sea fish paste with chlorine gas while stirring at a low speed of 6 rpm; the amount of chlorine in the low-value sea fish paste is 140 mg / L during the sterilization process;

[0068] c) Removal of odor: Heat the sterilized low-value marine fish paste at 85°C for 70 minutes, stir at 6 rpm while heating, and then filter out the water to obtain the low-value marine fish dry matter. Use water to remove the low-value marine fish dry matter. Wash 7 times, then add 4 times the weight of low-value marine fish dry matter to prepare low-value marine fish treatment slurry; after preparing the low-value marine fish treatment slurry, a...

Abstract

The invention relates to the technical field of fertilizer preparation, and discloses a method for producing an amino acid foliar fertilizer by low-value sea fish fermentation. The method comprises the following steps of pulp preparation, sterilizing, removal of foreign odor, preparation of an enzyme preparation, enzymolysis, deactivating, compounding and the like, wherein the enzyme preparation is prepared by compounding protease and an inorganic mineral carrier, so that the enzymolysis efficiency is higher; the low-value sea fishes are thoroughly decomposed, and can be easily absorbed by crops. The preparation method has the characteristics that a small amount of waste is produced, so that the pollution to environment is avoided; the efficiency is higher. The amino acid foliar fertilizer prepared by the method has the characteristics that the compounding is reasonable, the enough nutrient matters are contained, and the like; because the amino acid foliar fertilizer has better affinity with foliage, the amino acid foliar fertilizer can stay for a long time on the vegetable foliage, and the nutrient matter in the foliar fertilizer can be fully absorbed by the foliage.

Description

Technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a method for fermenting low-value marine fish to produce amino acid foliar fertilizer. Background technique [0002] Liquid protein fertilizer is a crop fertilizer made from waste animal and plant protein. Liquid protein fertilizers usually contain a large number of biological peptides, particularly rich in amino acids, and contain a variety of macroelements, trace elements, vitamins, etc. This fertilizer can improve the disease resistance and resistance of plants by means of synergistic effects with other effective ingredients. It can improve the quality of crops and promote plant growth. It is a new type of environmentally friendly animal and plant protein fertilizer. Amino acid foliar fertilizer is one of the main fertilizers in liquid protein fertilizers. [0003] my country is a large marine country, and the fishing and processing of marine aquatic products is quit...
