The invention provides a method for preparing a segmented enzymatic hydrolysis seaweed extract, belonging to the technical field of fertilizer synergist preparation, comprising the following steps: (1) crushing the seaweed and adding it to a mixed solution of sodium carbonate and sodium bicarbonate for heat preservation and soaking; (2) After adjusting the pH, adding a compound enzyme to carry out enzymolysis, and separating the filtrate to obtain an extract; (3) Freeze-drying the extract to powder to obtain the seaweed extract; the present invention combines the advantages of alkaline hydrolysis and enzymolysis , the seaweed is extracted in stages to reduce the influence of extraction conditions on the activity of the extracted products, and at the same time to speed up the extraction efficiency. |
