Embodiment 1

[0019] Embodiment 1: A kind of alkaline hydrolysis seaweed liquid, comprises the raw material of following weight portion: 350 parts of natural seaweed slurry, 150 parts of potassium hydroxide, 400 parts of deionized water, 10 parts of EDTA, 25 parts of citric acid, 20 parts of phosphoric acid, 200 parts of urea share.

Embodiment 2

[0020] Embodiment 2: a kind of preparation method of alkaline hydrolysis seaweed liquid, comprises the steps:

[0021] (1) Seaweed pretreatment: cut the seaweed into 3-5cm lengths; soak the seaweed in 0.1% potassium hydroxide solution for desalination and color protection;

[0022] (2) Ultrasonic enzymatic hydrolysis: add water 10 times the mass of seaweed, and adjust the pH to 6.8-7.2; in terms of mass, add 2% of the mass of seaweed, 2% of cellulase and glucoamylase, and ultrasonicate at 60°C Auxiliary enzymatic hydrolysis for 3 hours, and natural seaweed slurry was obtained after filtration;

[0023] (3) Compounding: The natural seaweed slurry obtained in step (2) is mixed with potassium hydroxide, deionized water, EDTA, citric acid, phosphoric acid, and urea according to the above-mentioned compounding to obtain an alkali-hydrolyzed seaweed liquid.

Embodiment 3

[0024] Embodiment 3: the difference with embodiment 1 is:

[0025] An alkaline hydrolyzed seaweed solution comprises the following raw materials in parts by weight: 370 parts of natural seaweed slurry, 155 parts of potassium hydroxide, 400 parts of deionized water, 10 parts of EDTA, 25 parts of citric acid, 20 parts of phosphoric acid, and 180 parts of urea.

Abstract

The invention discloses alkali-hydrolyzed seaweed liquid and a preparation method thereof, the alkali-hydrolyzed seaweed liquid is prepared from the following raw materials in parts by weight: 330 to 370 parts of natural seaweed slurry, 140 to 160 parts of potassium hydroxide, 380 to 420 parts of deionized water, 8 to 12 parts of EDTA (Ethylene Diamine Tetraacetic Acid), 24 to 26 parts of citric acid, 10 to 25 parts of phosphoric acid and 180 to 220 parts of urea. The seaweed is subjected to a deep enzymolysis wall-breaking technology, so that the nutrition of the seaweed liquid sprayed on the crops is changed into the nutrition which is beneficial for the crops to absorb, and the technical problem of low utilization rate of the seaweed fertilizer is solved.

Description

technical field [0001] The invention relates to the technical field of seaweed, in particular to an alkali hydrolyzed seaweed liquid 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, which can increase crop yield, improve quality and enhance crop resistance to drought, cold and disease. [0003] Seaweed fertilizer production methods can generally be divided into chemical hydrolysis, physical extraction, enzymatic hydrolysis, biological fermentation, etc., as well as fertilizers that extract biologically active substances from waste in the seaweed industry and then scientifically prepare them. The commonly used physical extraction method is to use high temperature and low pressure cool...
