Abstract

The invention discloses a method for preparing biocontrol active liquid seaweed fertilizers, and belongs to the technical field of agricultural bio-fertilizers. The method includes the steps that degummed seaweed dregs are subjected to ultrasonic treatment to obtain a first sample, and then compound enzymes are added into the first sample to carry out reacting; solid-liquid separation is carried out on enzymolysis reactants, and enzymatic hydrolysate is collected; finally, water-soluble chitosan with the degree of deacetylation larger than 90% and water-soluble chitosan oligosaccharide with the molecular weight ranging from 2,000 to 3,000 are added into the enzymatic hydrolysate, and the composite liquid fertilizers are prepared. As the degummed seaweed dregs are subjected to ultrasonic treatment, the structures of fibers can be changed under the acoustic cavitation effect of ultrasonic waves, amorphous regions of the fibers are enlarged accordingly, following enzymatic hydrolysis can be efficiently carried out easily, and the reaction speed and the reaction yield are increased. The oligomerization chitosan and seaweed dreg extract are compounded, the advantages of the two kinds of raw materials are complemented, the fertilizers are more complete in function and higher in fertilizer effect, and the fertilizers prepared with the method are novel seaweed biocontrol fertilizers having the treatment function, the disease preventing function and the nursing function at the same time.

Description

technical field [0001] The invention relates to the technical field of agricultural biological fertilizers, in particular to a preparation method of biocontrol active liquid seaweed fertilizer. Background technique [0002] In addition to being edible, seaweed also has great industrial value. At present, the processing of large seaweed mainly involves the production of alginate, agar gum and carrageenan. The industrial extraction process of seaweed, especially alginate, produces a large amount of waste residue Emissions can cause problems such as environmental pressure. In the solid residue of the seaweed gum industrial extraction process (hereinafter referred to as degummed seaweed residue), it contains a large amount of components such as cellulose, hemicellulose, lignin, protein and trace elements after detection and analysis. The specific component detection results are shown in Table 1 As shown in Table 2, the protein amino acid analysis results of degummed seaweed res...
