Abstract

The invention belongs to the field of seaweed fertilizer and particularly relates to a preparation method of compound seaweed fertilizer. The preparation method comprises the processes of pretreatment, enzymolysis, microbiological treatment, drying and the like. According to the preparation method provided by the invention, fresh raw materials are treated in a low-temperature frozen-breaking manner, so that the active ingredients of seaweed can be effectively protected and the prepared compound seaweed fertilizer can be full of nutriments; by adoption of such a manner that a plurality of enzymes are combined, the macro-molecular sugar and protein ingredients in a seaweed homogenate can be effectively degraded and the extraction efficiency of soluble matters in the seaweed can be improved; and the compound seaweed fertilizer is prepared by utilizing enzymolysis compound microorganisms through fermentation, so that the active ingredients of the seaweed can be retained to the greatest extent, the efficacy of the compound seaweed fertilizer can be improved, and the relatively good application prospect can be achieved.

Description

technical field [0001] The invention belongs to the field of seaweed fertilizer, and in particular relates to a preparation method of compound seaweed fertilizer. Background technique [0002] Seaweed is a general term for marine algae such as kelp, seaweed, wakame, and agarose. It is an algae that grows in the sea and is a cryptogamous plant in the plant kingdom. Many species of algae generate energy through photosynthesis. There are many types of seaweed, including brown algae, red algae, and green algae. Common brown algae include macrophylla, sargassum, and fucus. Brown algae in seaweed are rich in polysaccharides, such as: algin, fucoidan and kelp starch, etc. These polysaccharides are lacking in many land plants. Alginate is a block linear polymer composed of two monomers, mannuronic acid and guluronic acid. It has gel, chelating and hydrophilic properties, and it can change some soil properties through these properties. properties, it can be used as a soil condition...
