Abstract

The invention discloses a method for producing an agricultural seaweed extracting solution by a physical and biological combination method and the seaweed extracting solution. The method comprises thefollowing steps of: (1) pretreatment: taking dry seaweed, and crushing the dry seaweed to 40-80 meshes to obtain seaweed meal; (2) wall breaking: mixing a keep-alive agent with seaweed meal, and carrying out physical wall breaking according to a weight ratio of the seaweed meal to the keep-alive agent of 1: (5-10) to obtain a mixture; (3) enzymolysis: taking alginate lyase, adding the alginate lyase into the mixture, and carrying out enzymolysis for 4-8 hours at the temperature of 35-55 DEG C; (4) inactivation: carrying out inactivation for 5-10 min at the inactivation temperature of 90-100 DEG C ; and (5) filtering and sub-packaging to obtain the seaweed extracting solution. The seaweed extracting solution is high in extracting rate and low in molecular weight of active ingredients, canbe absorbed by plants, keeps the activity of plant growth regulator substances, can be stored for a long time, and has the effects of promoting plant growth, regulating the ecological environment of soil, improving the utilization rate of fertilizers, resisting biological stress and abiotic stress and the like.

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...
