specific Embodiment 1

[0026] (1) Preparation of seaweed powder active carrier

[0027] Select 10kg of seaweed residue after extracting seaweed gum, carrageenan, and agar gum as raw material, and put it into a calcification tank for calcification. Add hydrochloric acid with a concentration of 1% by weight to make its pH value reach 5, then add 6% calcium chloride solution by weight to make it flocculate completely, and remove the excess calcium chloride and hydrochloric acid solution in the calcified flocs with clear water Rinse well; dehydrate the calcified floc to obtain a dehydrated solid with a water content of 65%; crush the dehydrated solid into a seaweed powder active carrier with a particle size within the range of 4 mesh to 10 mesh for future use.

[0028] (2) Preparation of seaweed mixture

[0029] Wash 5kg of fresh kelp with fresh water, pulverize it with a pulverizer, freeze it at a low temperature for 6 hours, add 15kg of ethanol solution with a concentration of 70% by weight, mix it a...

[0032] (1) Preparation of seaweed powder active carrier

[0033] Select 10kg of seaweed residue after extracting seaweed gum, carrageenan, and agar gum as raw material, and put it into a calcification tank for calcification. Add hydrochloric acid with a concentration of 1.5% by weight to make its pH value reach 5, then add 10% calcium chloride solution by weight to make it flocculate completely, and use clear water to dissolve the excess calcium chloride and hydrochloric acid solution in the calcified flocs Rinse well; dehydrate the calcified flocs to obtain dehydrated solids with a water content of 75%; crush the dehydrated solids into seaweed powder active carriers with particle sizes ranging from 4 mesh to 20 mesh for future use.

[0034] (2) Preparation of seaweed mixture

[0035] Wash 5kg of fresh kelp with fresh water, pulverize it with a pulverizer, freeze it at a low temperature for 4 hours, add 15kg of ethanol solution with a concentration of 80% by weight, mix it an...

[0038] (1) Preparation of seaweed powder active carrier

[0039] Select 10kg of seaweed residue after extracting seaweed gum, carrageenan, and agar gum as raw material, and put it into a calcification tank for calcification. Add hydrochloric acid with a concentration of 2% by weight to make its pH value reach 5.5, then add 8% calcium chloride solution by weight to make it flocculate completely, and remove the excess calcium chloride and hydrochloric acid solution in the calcified flocs with clear water Rinse well; dehydrate the calcified flocs to obtain dehydrated solids with a water content of 60%; crush the dehydrated solids into seaweed powder active carriers with particle sizes ranging from 15 mesh to 20 mesh for future use.

Abstract

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.

Description

technical field [0001] The invention relates to a preparation method of fertilizer, in particular to a preparation method of seaweed biological long-acting fertilizer using seaweed as raw material. Background technique [0002] Seaweed fertilizer has been developed so far, and its effect mainly depends on the processing technology and method of seaweed. In terms of extraction process, similar foreign products mainly use hot water to extract dry or wet seaweed, and sometimes need to add sodium carbonate or potassium hydroxide for hydrolysis, such as alkaline hydrolysis, high temperature or high pressure dehydration, etc. But these traditional extraction processes seriously destroy some active components of seaweed or reduce the content of active components therein. In recent years, a large number of various "seaweed fertilizers" have emerged on the market. However, some of these products contain very low seaweed ingredients, and the fertilizer effect is not long-lasting. Ac...
