Embodiment 1

[0030] Wash the hijiki with tap water, and then soak it in tap water for 72 hours, changing the water every 6 hours during this period; chop the hijiki after soaking with a knife (width: about 0.5 cm, length: about 5 cm), mince Hijiki is pulverized by a colloid mill. After crushing, Hijiki vegetable puree and distilled water are mixed at a volume ratio of 1:30, and the suspension is processed by a high-pressure homogenizer; the working conditions of the homogenizer: pressure 20 MPa, cycle times 3 times, flow rate 1000 liters / hour, room temperature conditions . 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 50% bleaching powder solution at a mass ratio of 1:16, shake in a shaker, press 220 rpm After shaking for 2 minutes, the rotation speed was adjusted to 40 rpm, the temperature was controlled at 35°C, and the shaking time was 48 hours. After shaking, the...

Abstract

The invention discloses a seaweed fertilizer preparation method taking sargassum fusiforme as raw material. The sargassum fusiforme performs the combined pretreatment method of a colloid mill and a high pressure homogenizer and the enzyme pueraria root residue fixation method; the acquired seaweed slurry is biologically catalyzed and transformed through the fixation enzyme two-step method enzymolysis technology, the algal polysaccharides and protein are respectively degraded to be alga oligosaccharides and polypeptide; finally, a continuous production technique of seaweed fertilizer prepared by sargassum fusiforme enzymolysis on the basis of a continuous flow mixing tank type reactor is established; through centrifugation of the enzymatic hydrolysate, the liquid supernatant and sargassum fusiforme residue are acquired; through falling film evaporation, the liquid supernatant is prepared to be concentration fluid; the ultra-filter fluid is seaweed fertilizer; sargassum fusiforme residueand the oil tea seed cake are fermented together to form solid organic fertilizer, thus the purpose of using full cells of the sargassum fusiforme is reached. The seaweed fertilizer preparation method has the advantages of improving the resource utilization efficiency of sargassum fusiforme, improving the sargassum fusiforme processing technology and seaweed fertilizer production level, realizingthe repeat and continuous use of enzyme, reducing the enzyme consumption, and lowering the production cost of the seaweed fertilizer; the product is good in quality, pure nature, and free from pollution 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...
