Problems solved by technology

Although the inactivation treatment can serve the purpose of preservation and storage, because the high temperature treatment will inevitably damage the active ingredients of seaweed, and kill the active enzymes that can promote the growth of crops, reducing the fertilizer efficiency

preparation example Construction

[0036] First, the present invention provides a kind of preparation method of the liquid fertilizer that has active enzyme, seaweed full price nutrition, comprises the steps:

[0037] (1) Utilizing a compound enzyme to enzymatically hydrolyze seaweed at a first temperature to obtain a seaweed enzymolysis solution;

[0038] (2) Filtrate the seaweed enzymolysis solution at a second temperature to obtain a seaweed clear liquid; wherein, the second temperature is lower than the first temperature, and the complex enzyme cannot carry out enzymatic reactions;

[0039] (3) Concentrating the seaweed supernatant to obtain a concentrated supernatant; and

[0040] (4) adding acid protease to the concentrated supernatant, and then adjusting the pH of the concentrated supernatant to 6.5-7.0 to prepare the liquid fertilizer.

[0041] First of all, the present invention inhibits the activity of the enzyme remaining in the enzymolysis solution through low temperature treatment. At the second ...

Embodiment 1

[0071] S11:

[0072] Soak the collected seaweed in clear water to remove impurities in the seaweed and reduce its salt content, then fish out the seaweed and crush it, add water 4 times the quality of the seaweed to the crushed seaweed, and mix well to obtain Seaweed slurry for enzymatic hydrolysis.

[0073] Add the composite enzyme (in composite enzyme, the enzyme activity ratio of cellulase, pectinase, protease and amylase that is made up of cellulase, pectinase, protease and amylase to be 6:1.5 in described seaweed pulp :1:0.8), after mixing evenly, carry out enzymatic hydrolysis at 42°C, after compound enzyme enzymatic hydrolysis, the seaweed slurry becomes a mixed liquid mixed with seaweed enzymatic hydrolysis products and compound enzymes, which is the seaweed enzymatic hydrolysis solution.

[0074] The enzymatic hydrolysis process is a conventional process in the art, and will not be described in detail here.

[0075] S12:

[0076] At 10° C., the seaweed enzymolysis ...

Abstract

The invention relates to liquid fertilizer having an active enzyme and full nutrients of seaweed and a preparation method thereof. The preparation method comprises (1) carrying out enzymolysis on seaweed through compound enzymes at a first temperature to obtain a seaweed enzymatic hydrolysate, (2) filtering the seaweed enzymatic hydrolysate at a second temperature to obtain a clear seaweed liquid, wherein the second temperature is lower than the first temperature and the compound enzymes cannot undergo an enzymatic reaction at the second temperature, (3) concentrating the clear seaweed liquid to obtain a concentrated clear liquid, and (4) adding an acidic protease into the concentrated clear liquid and adjusting the pH of the concentrated clear liquid to 6.5 to 7 so that the liquid fertilizer is obtained. The preparation method realizes long-term preservation without high temperature inactivation treatment, does not damage the active enzyme and nutrients in the seaweed and ensures full nutrients of seaweed and active enzyme in the liquid fertilizer.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a liquid fertilizer with active enzymes and seaweed full-value nutrition and a preparation method thereof. Background technique [0002] Seaweed is a rich source of marine organisms, widely used in food, industrial raw materials, and herbal medicines. Seaweed has been used in agriculture and livestock production for centuries. Seaweed fertilizer is a new type of pure natural, non-toxic and side-effect fertilizer. It contains rich non-N organic matter and a certain amount of amino acids, proteins and micronutrients, and also contains seaweed polysaccharides, alginic acid, and alginic acid unique to marine organisms. Unsaturated fatty acids and mineral elements such as zinc, bromine and iodine, which are rare in terrestrial plants, and rich in vitamin C and B 1 , B 2 , B 12 , D, E, K and other nutrients have the functions of increasing crop yield, improving quality and enha...
