Abstract

The invention discloses high-water-retention slow-release seaweed fertilizer and a preparation method thereof. The high-water-retention slow-release seaweed fertilizer comprises the following raw materials in parts by weight: seaweed, diatomite, carboxymethyl cellulose sodium, bentonite, chitosan, bean pulp, a dispersing agent, lauryl sodium sulfate, calcium superphosphate, methylcellulose and distilled water. The preparation method comprises the following steps: S1, performing washing, air drying and crushing on the seaweed, so as to obtain seaweed particles; S2, performing mixing and enzymolysis on the seaweed particles and other mixtures, so as to obtain a mixed solution; S3, centrifuging the mixed solution, collecting supernate, and performing fermentation; S4, preparing a membranous solution; S5, applying the membranous solution, so as to obtain a flexible glue piece; S5, laying a fermentation product into the flexible glue piece, so as to obtain the high-water-retention slow-release seaweed fertilizer. The fertilizer has the advantages that seaweed fertilizer is packaged in a membranous material, the membranous material, along with washing of rainwater or irrigation water, gradually releases the seaweed fertilizer into soil, and slow release is formed, so that a sower can reduce the applying frequency of the seaweed fertilizer during sowing.

Description

technical field [0001] The invention relates to the technical field of seaweed fertilizer, in particular to a slow-release seaweed fertilizer with high water retention and a preparation method thereof. Background technique [0002] The algal body is grass-green, tubular and membranous, clustered, with obvious main branches and slender branches, up to 1 meter high. The base is attached to the rock with a fixator, and grows on tidal flats and gravels in the mid-tidal zone. Due to global climate change, water eutrophication and other reasons, the green tide of the large marine alga Enteromorpha broke out. A large amount of Enteromorpha floats and gathers on the shore, blocking the waterway and destroying the marine ecosystem, seriously threatening the development of coastal fishery and tourism. Most types of marine products are widely distributed in oceans all over the world, and some species are found in brackish water or rivers. Also visible. It often grows on rocks or bog...
