The invention relates to a method for preparing seaweed biological long-acting fertilizer. Seaweed dregs from which seaweed gum, carrageenan and agar are extracted are taken as an active carrier so as to turn waste into treasure, and a plurality of seaweed bio-active substances contained in seaweed extract and chelated-type nutritive elements or nutrients easily absorbed by plants are all wrapped up to form a slow-release system so as to ensure slow long-term release of fertilizer efficiency and provide plants with demand for nutrition throughout a growing season. The method extracts nutrient components in seaweed adopting a low-temperature extraction process, thereby ensuring that active components of the seaweed are not destroyed and increase the content of the effective nutrient components of products. The method adopts a special biochemical process, adds a multifunctional fermentation strain which has synergy and is formed mainly by compounding fungi, yeast, actinomycetes and bacterial beneficial microorganisms which are not mutually antagonistic and cooperate during fermentation, and effectively extracts biological nutrient components of the seaweed through a large amount of powerful biochemical reaction during reproduction. The seaweed biological long-acting fertilizer belongs to non-toxic pollution-free purely-natural seaweed bio-organic fertilizer.
