Embodiment Construction

[0035] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0036] A preparation method of compound seaweed fertilizer, comprising the following steps:

[0037] (1) Pretreatment: first collect fresh wild pine knotweed, sugar kelp, sand algae, carnetella and fucus, then wash repeatedly with clean water to remove impurities, clean and mix to obtain mixed algae, and squeeze the mixed algae Dehydrate to a water content of 40-45%; freeze the dehydrated mixed algae at -25°C for 4 hours, take it out and thaw it at room temperature, and first use a tissue grinder to crush it to 60-80 mesh, and then use a colloid mill to crush it to 200-250 mesh Obtain the mixed algae powder; finally add water to the mixed algae powder according to the material-to-water ratio of 1:0.45, mix and stir to make a homogenate;

[0038] (2) Enzyme extraction: first add 2.0-2.5g / L exo-β-1,4 glucanase and 1.5-2.5g / L cellobiohydro...

Abstract

The invention belongs to the technical field of seaweed fertilizer, and more specifically relates to a preparation method of a composite seaweed fertilizer, and the composite seaweed fertilizer. The preparation method comprises following steps: 1, pretreatment; 2, enzyme extraction; 3, microorganism extraction; and 4, fertilizer preparation. The preparation method is capable of maintaining the effective active ingredients of seaweed as much as possible, and increasing extraction ratio of the effective ingredients greatly.

Description

technical field [0001] The invention belongs to the technical field of seaweed fertilizer, and in particular relates to a preparation method of a compound seaweed fertilizer and the compound seaweed fertilizer. Background technique [0002] Seaweed is a lower cryptogamous plant that grows in the ocean. It is rich in proteins, amino acids, inorganic salts, vitamins, alginate and a small amount of enzymes, plant hormones, polyphenols and polysaccharides and other physiologically active substances. After biochemical treatment, it can be used as a new type of fertilizer, which has the functions of increasing production, reducing diseases, reducing drug residues, and improving flavor. [0003] The technical difficulty of using seaweed to produce seaweed fertilizer is mainly to retain the macroelements, trace elements, cytokinin, gibberellin, Active ingredients such as cytokinins, polyphenol compounds and antibiotics. At present, the domestic seaweed fertilizer production proces...
