Abstract

The invention discloses a method for producing agricultural seaweed extract and the seaweed extract by a combined physical and biological method. The present invention comprises the following steps: 1) pretreatment: take dried seaweed, pulverize it to 40-80 meshes to obtain seaweed powder; 2) wall breaking: take a life-preserving agent, mix it with seaweed powder, physically break the wall, seaweed powder and life-preserving agent The weight ratio is 1:5-10 to obtain a mixture; 3) Enzymolysis: take alginate lyase and add it to the mixture, the enzymolysis temperature is 35-55°C, and the enzymolysis time is 4-8h; 4) Inactivation: The inactivation temperature is 90-100° C., and the inactivation time is 5-10 minutes; 5) Filtrate and subpackage to obtain seaweed extract. The seaweed extract of the present invention has high extraction rate, low molecular weight of active ingredients, can be absorbed by plants, maintains the activity of plant growth regulators, can be stored for a long time, has the functions of promoting plant growth, regulating soil ecological environment, improving fertilizer utilization rate, Resistance to biotic and abiotic stresses.

Description

technical field [0001] The invention belongs to the technical field of plant extracts, in particular to a method for producing agricultural seaweed extract by a physical-biological combination method and the seaweed extract. Background technique [0002] The ocean covers about 71% of the earth's surface area, accounts for 97% of the earth's total water volume, and is the largest resource treasure house on the earth. As the largest biological population in the ocean, seaweed contains a large number of highly active biomass components, including polysaccharides, proteins, mannitol, betaine, iodine, polyphenols, unsaturated fatty acids, sterols, terpenoids, mineral elements, poly Amines, plant growth regulators, vitamins, pigments, etc. have excellent biological activity and are not only widely used in many fields such as biomedicine, functional food, animal feed, and cosmetics, but also have important application value in ecological fertilizers. [0003] At present, the extra...
