Embodiment 1

[0017] 1) Preparation of fish protein degradation solution;

[0018] Select 600kg of frozen tuna skin, after thawing at normal temperature, put it into the degradation kettle; pump 100kg of clean tap water; put in concentrated sulfuric acid until the pH is 3.0-4.0; heat up to 121°C, 0.121MPa, high temperature and high pressure for 8-10h for acidolysis;

[0019] After cooling and reducing the pressure, the feed liquid is pumped into the plate frame for filtration, and the filtrate is the prepared tuna protein degradation liquid.

[0020] 2) Preparation of seaweed degradation solution;

[0021] Select 500kg of fresh kelp, put it into the reaction kettle, pump 100kg of clean tap water; put in potassium hydroxide to adjust the pH to 10-11; heat up to 121°C, 0.121MPa, high temperature and high pressure for 8-10h for alkaline hydrolysis;

[0022] After cooling and reducing the pressure, the feed liquid is pumped into a horizontal centrifuge for filtration, and the filtrate is conce...

Embodiment 2

[0028] 1) Preparation of fish protein degradation solution;

[0029] Select 500kg of frozen Spanish fin viscera and put it into the degradation kettle; pump 300kg of clean tap water; put in 1kg of protease, use concentrated sulfuric acid until the pH is 6.0-7.0; heat up to 45°C, degrade at room temperature for 18 hours for enzymolysis;

[0030] The feed liquid is pumped into a horizontal centrifuge for filtration, and the filtrate is the prepared mackerel protein degradation liquid.

[0031] 2) Preparation of seaweed extract;

[0032] Select 500kg of fresh sargassum, put it into the reaction kettle, pump 100kg of clean tap water; put in concentrated sulfuric acid to adjust the pH to 3-4; heat up to 121°C, 0.121MPa, high temperature and high pressure for 8-10h for acidolysis;

[0033] After cooling and reducing the pressure, the feed liquid is pumped into the plate frame for filtration, the filtrate is concentrated 3 times by three-effect concentration, and the concentrated li...

Embodiment 3

[0039] 1) Preparation of fish protein degradation solution

[0040] Select 600kg of frozen cod skin, after thawing at room temperature, put it into the degradation kettle; pump 100kg of clean tap water; put in potassium hydroxide until the pH is 10.0-11.0; heat up to 121°C, 0.121MPa, high temperature and high pressure for 8-10h for alkaline hydrolysis;

[0041] After cooling and reducing the pressure, drop in an appropriate amount of phosphoric acid to adjust the pH to neutral, pump the feed liquid into the plate frame for filtration, and the filtrate is concentrated twice through the three-effect concentration tower, which is the prepared cod protein degradation liquid.

[0042] 2) Preparation of seaweed degradation solution

[0043] Select 600kg of fresh Enteromorpha, put it into the reaction kettle, pump 50kg of clean tap water; put in potassium hydroxide to adjust the pH to 10-11; raise the temperature to 121°C, 0.121MPa, high temperature and high pressure for 8-10h for al...

Abstract

The invention provides a preparation method of alga and fish protein biological bacterial manure. The preparation method is characterized in that raw materials of a degradation solution, decomposed products and the like of living bodies, dry products and the like of marine alga and one or several raw materials of fish skin, fish flesh, fish viscera, fish bone and the like of marine fishes are utilized; the degradation solution prepared in methods of enzymolysis, acidolysis, alkaline hydrolysis and the like is supplemented by one or several raw materials of humic acid, turf, bentonite, talcum powder, montmorillonite powder and the like; one or more of bacterial solution and bacterial powder of microorganism strains like bacillus stains of bacillus subtilis, bacillus amyloliquefaciens and the like, saccharomyces strains of saccharomyces cerevisiae and the like, lactobacillus strains of lactobacillus bulgaricus and the like are compounded to be prepared into the fish protein biological bacterial manure.

Description

technical field [0001] The invention relates to a preparation method of seaweed fish protein microbial fertilizer. Background technique [0002] With the continuous development of agricultural production in our country, related technologies such as planting, agricultural machinery, chemical fertilizers, and pesticides have continued to improve. Due to the extensive use of chemical fertilizers in my country's agricultural production in the early stage, serious consequences such as soil fertility decline, compaction, and soil-borne diseases have been caused. At present, the area of ​​domestic land use tends to be tense, the area of ​​agricultural production land is shrinking, the area of ​​land acidification, salinization, and desertification is increasing year by year, and the area of ​​high-quality agricultural land is continuously decreasing. [0003] In recent years, my country has vigorously advocated the use of organic fertilizers, green fertilizers, and microbial ferti...
