Embodiment 1

[0030] Wash the leftovers of kelp with tap water, then soak them in tap water for 24 hours, during which the water is changed every 3 hours; the leftovers after soaking are chopped with a knife (width: about 0.5 cm, length: about 5 cm), and the broken kelp is cleaned by colloid Grind to crush. The pulverized kelp 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 40 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 10% bleaching powder solution at a mass ratio of 1:5, oscillate in a shaker, press 100 rpm After shaking for 10 minutes, the rotation speed was adjusted to 50 rpm, the temperature was controlled at 30°C, and the shaking time was 24 hours. After shakin...

Embodiment 2

[0033] Wash the leftovers of kelp with tap water, then soak them in tap water for 24 hours, during which the water is changed every 3 hours; the leftovers after soaking are chopped with a knife (width: about 0.5 cm, length: about 5 cm), and the broken kelp is cleaned by colloid Grind to crush. The pulverized kelp mud and distilled water are mixed at a volume ratio of 1:20, and the suspension is processed by a high-pressure homogenizer; the working conditions of the homogenizer are: pressure 60 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 40% bleaching powder solution at a mass ratio of 1:15, oscillate in a shaker, press 200 rpm After shaking for 30 minutes, the rotation speed was adjusted to 150 rpm, the temperature was controlled at 50° C., and the shaking time was 48 hours. After t...

Embodiment 3

[0036] Wash the leftovers of kelp with tap water, then soak them in tap water for 24 hours, during which the water is changed every 3 hours; the leftovers after soaking are chopped with a knife (width: about 0.5 cm, length: about 5 cm), and the broken kelp is cleaned by colloid Grind to crush. The pulverized kelp 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 50 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: wash 4 times with distilled water, place in a beaker, mix kudzu root slag and 25% bleaching powder solution at a mass ratio of 1:10, shake in a shaker, press 150 rpm After shaking for 20 minutes, the rotation speed was adjusted to 100 rpm, the temperature was controlled at 40°C, and the shaking time was 36 hours. After the shaki...

Abstract

The invention discloses a preparation method of a seaweed fertilizer; a kelp leftover material is used as a raw material, through a colloid mill and high pressure homogenizer combined pretreatment method and a pueraria root residue immobilization method of an enzyme, an obtained seaweed homogenate is subjected to biocatalytic conversion by an immobilized enzyme two-step enzymatic hydrolysis process, and the objective that seaweed polysaccharide and proteins are respectively degraded into seaweed oligosaccharides and polypeptides is realized; finally, a continuous production process for preparing the seaweed fertilizer by kelp enzymatic hydrolysis based on a continuous flow stirring tank type reactor is established, an enzymatic hydrolysate is centrifuged to obtain a supernatant and a kelpresidue, the supernatant is subjected to film falling evaporation into a concentrated liquid, and an ultrafiltrate is a seaweed liquid fertilizer; the kelp enzymatic hydrolysis residue, oil tea cakesand the like are co-fermented into a solid organic fertilizer, and the purpose of kelp whole-cell utilization is achieved. The kelp resource utilization efficiency is improved, the kelp processing technology and the seaweed fertilizer production level are improved, the repeated and continuous use of the enzyme is realized, the consumption of the enzyme is reduced, the production cost of the seaweed fertilizer is reduced, and the product is good in quality, pure natural, pollution-free and 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...
