Problems solved by technology

[0002] Seaweed is rich in nutrients, and there are dozens of active substances, including seaweed polysaccharides, betaine, endogenous hormones (plant auxin, gibberellin, zeatin, etc.), phenolic compounds, Mannitol, etc., most of these active ingredients exist in the cell wall of seaweed, and it is difficult to be absorbed and utilized by plants when applied directly. The active ingredients are extracted, and the extraction method has a great impact on the content of active substances and nutrients in the product
[0003] At present, most seaweed fertilizer manufacturers use chemical methods to produce seaweed fertilizers, mainly heating with strong acid and strong alkali to break the walls of seaweed cells. The biggest defect of this method is that strong acid and strong alkali will destroy the activity of nutrients in seaweed , resulting in a great loss of active ingredients of seaweed, which ultimately affects the use effect of seaweed fertilizer products

Abstract

The invention relates to an active seaweed fertilizer and a production method thereof. The preparation method comprises the steps of digestion, enzymolysis, post-treatment and the like. The production method is characterized in that the digestion of weak base is performed before complex enzymes are added, so that large damages on active substances in seaweeds can not be caused, and the preliminary extraction of the seaweeds can be facilitated, so that the dosage of the complex enzymes can be reduced. The seaweed fertilizer product is rich in alginic acid, gibberellin, zeatin and the other active substances, can effectively promote the growth and development of plants and improve the plant yield, and meanwhile greatly keeps the natural adverse resistance ingredient glycine betaine, phenol compounds and the like in the seaweeds, so that the improvement of the stress resistance of the plants can be facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of fertilizer production. More specifically, the present invention relates to a method for preparing active seaweed fertilizer from natural seaweed, and also relates to the active seaweed fertilizer. 【Background technique】 [0002] Seaweed is rich in nutrients, and there are dozens of active substances, including seaweed polysaccharides, betaine, endogenous hormones (plant auxin, gibberellin, zeatin, etc.), phenolic compounds, Mannitol, etc., most of these active ingredients exist in the cell wall of seaweed, and it is difficult to be absorbed and utilized by plants when applied directly. The essence of seaweed fertilizer is the natural active substance rich in seaweed itself. The active ingredients are extracted, and the extraction method has a great influence on the content of active substances and nutrients in the product. [0003] At present, most seaweed fertilizer manufacturers use chemical methods...
