Embodiment 1

[0030] Wash the sargassum with tap water, then soak it in tap water for 18 hours, and change the water every 2 hours during this period; chop the soaked sargassum with a knife (width: about 0.5 cm, length: about 5 cm), crushed sargassum Pulverized by colloid mill. After crushing, the sargassum mud and distilled water are mixed at a volume ratio of 1:2, and the suspension is processed by a high-pressure homogenizer; the working conditions of the homogenizer are: pressure 15 MPa, cycle times 3 times, flow rate 1000 liters / hour, room temperature. Pueraria slag pretreatment method produced in the production process of kudzu root powder: wash 3 times with distilled water, put it in a beaker, mix kudzu root slag and 3% bleaching powder solution at a mass ratio of 1:1, oscillate in a shaker, press 200 rpm After shaking for 2 minutes, the rotation speed was adjusted to 40 rpm, the temperature was controlled at 40°C, and the shaking time was 12 hours. After shaking, the kudzu root resi...

Embodiment 2

[0033] Wash the sargassum with tap water, then soak it in tap water for 18 hours, and change the water every 2 hours during this period; chop the soaked sargassum with a knife (width: about 0.5 cm, length: about 5 cm), crushed sargassum Pulverized by colloid mill. After crushing, the sargassum mud and distilled water are mixed at a volume ratio of 1:5, and the suspension is processed by a high-pressure homogenizer; the working conditions of the homogenizer are: pressure 30 MPa, cycle times 5 times, flow rate 1000 liters / hour, room temperature. Pueraria slag pretreatment method produced in the production process of kudzu root powder: wash 5 times with distilled water, put it in a beaker, mix kudzu root slag and 10% bleaching powder solution at a mass ratio of 1:5, shake in a shaker, press 300 rpm After shaking for 10 minutes, the rotation speed was adjusted to 40 rpm, the temperature was controlled at 40°C, and the shaking time was 12 hours. After shaking, the kudzu root residu...

Embodiment 3

[0036] Wash the sargassum with tap water, then soak it in tap water for 18 hours, and change the water every 2 hours during this period; chop the soaked sargassum with a knife (width: about 0.5 cm, length: about 5 cm), crushed sargassum Pulverized by colloid mill. After pulverization, the sargassum mud and distilled water are mixed at a volume ratio of 1:4, and the suspension is processed by a high-pressure homogenizer; the working conditions of the homogenizer are: pressure 20 MPa, cycle times 4 times, flow rate 1000 liters / hour, room temperature. Pueraria slag pretreatment method produced in the production process of kudzu root powder: Rinse 4 times with distilled water, put in a beaker, mix kudzu root slag and 8% bleaching powder solution at a mass ratio of 1:3, oscillate in a shaker, press 250 rpm After shaking for 6 minutes, the rotation speed was adjusted to 80 rpm, the temperature was controlled at 50°C, and the shaking time was 18 hours. After shaking, the kudzu root r...

Abstract

The invention relates to a seaweed fertilizer preparation method taking gulfweed as a raw material. Seaweed homogenate is prepared from the gulfweed by a combined colloid mill and high-pressure homogenizer pretreatment method and a radix puerariae slag immobilization method of an enzyme, and subjected to biological catalysis conversion by a two-step enzymolysis technology of the immobilized enzyme; an objective of degrading algal polysaccharides and proteins into seaweed oligosaccharide and polypeptide respectively is achieved; finally, a continuous production technology of preparing a seaweedfertilizer by gulfweed enzymolysis based on a continuous flow mixing tank reactor is established; a supernate and a gulfweed residue are obtained by centrifuging enzymolysis liquid; the supernate issubjected to falling film evaporation to form concentrated liquid; an ultrafiltrate is the seaweed liquid fertilizer; the kelp enzymolysis residue, an oil tea cake and the like are fermented to form asolid organic fertilizer; and the purpose of full cell utilization of the gulfweed is achieved. According to the method, the gulfweed resource use efficiency is improved; a gulfweed processing technology is improved; a seaweed fertilizer production level is raised; the repeated and continuous use of the enzyme is achieved; the consumption of the enzyme is reduced; the production cost of the seaweed fertilizer is lowered; a product is good in quality and all natural; and no pollutants are degradable.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a preparation method of seaweed fertilizer. Background technique [0002] Seaweed fertilizer is a bio-fertilizer made of seaweed as the main raw material and scientifically processed. The main components are natural biologically active substances extracted from seaweed that are beneficial to plant growth and development, and seaweed absorbed from the ocean and enriched in the body. Mineral nutrients, including seaweed polysaccharides, phenolic polymers, mannitol, betaine, plant growth regulators (cytokinins, gibberellins, auxin, and abscisic acid, etc.) and nitrogen, phosphorus, potassium, and Iron, boron, molybdenum, iodine and other trace elements. In addition, in order to increase the fertilizer efficiency and the chelating effect of the fertilizer, a proper amount of humic acid and trace elements are also dissolved. [0003] Compared with traditional fertilizers, sea...
