Embodiment 1

[0021] Kelp slag and distilled water were mixed at a mass ratio of 1:20, stirred with a magnetic stirrer at 100 rpm for 10 minutes, then centrifuged at 8000 rpm for 5 minutes, and the supernatant was removed after centrifugation; the above process was repeated 3 times, and freeze-dried. After pretreatment, mix the kelp slag and distilled water with a mass ratio of 1:30, place it in the reactor, add enzyme according to the mass ratio of kelp slag and enzyme 100:1, adjust the pH to 4.5, stir at 100 rpm, and stir for 5 minutes Finally, the stirring speed was adjusted to 50 rpm, and the entire enzyme biocatalytic conversion reaction process was 3 hours, and the temperature was controlled at 45°C; 15 minutes after the start of the reaction, the strategy of continuously adding kelp residue and enzyme was adopted, cellulase and β- The glucosidase is mixed at a mass ratio of 1:1; the added kelp slag and enzyme are mixed at a mass ratio of 5:1, and the kelp slag and enzyme mixture are c...

Embodiment 2

[0023] Kelp slag and distilled water were mixed at a mass ratio of 1:6, stirred with a magnetic stirrer at 100 rpm for 10 minutes, then centrifuged at 8000 rpm for 5 minutes, and the supernatant was removed after centrifugation; the above process was repeated 3 times, and freeze-dried. After pretreatment, mix the kelp slag and distilled water at a mass ratio of 1:10, place it in the reactor, add enzyme according to the mass ratio of kelp slag and enzyme 10:1, adjust the pH to 6.5, stir at 200 rpm, and stir for 15 minutes Finally, the stirring speed was adjusted to 150 rpm, and the entire enzyme biocatalytic conversion reaction process was 3 hours, and the temperature was controlled at 65°C; 30 minutes after the start of the reaction, the strategy of continuously adding kelp residue and enzyme was adopted, cellulase and β- The glucosidase is mixed at a mass ratio of 5:1; the added kelp slag and enzyme are mixed at a mass ratio of 100:1, and the kelp slag and enzyme mixture are c...

Embodiment 3

[0025] Kelp slag and distilled water were mixed at a mass ratio of 1:10, stirred with a magnetic stirrer at 100 rpm for 10 minutes, then centrifuged at 8000 rpm for 5 minutes, and the supernatant was removed after centrifugation; the above process was repeated 3 times, and freeze-dried. After pretreatment, the kelp slag and distilled water are mixed at a mass ratio of 1:20, placed in the reactor, and the enzyme is added according to the mass ratio of kelp slag and enzyme of 40:1, the pH is adjusted to 6.0, the stirring speed is 150 rpm, and stirring is carried out for 10 minutes Finally, the stirring speed was adjusted to 100 rpm, and the entire enzyme biocatalytic conversion reaction process was 3 hours, and the temperature was controlled at 60°C; 30 minutes after the start of the reaction, the strategy of continuously adding kelp slag and enzymes, cellulase and β- The glucosidase is mixed at a mass ratio of 2:1; the added kelp slag and enzyme are mixed at a mass ratio of 20:1...

Abstract

The invention discloses a preparation method of grape special purpose seaweed fertilizer. The preparation method utilizes sodium alginate production enterprise by-product kelp slag as a raw material, builds a raw material pretreatment method and develops a bio-refining technology for two-step catalytic conversion of kelp slag based on an enzyme. Through the establishment of substrate and enzyme feeding strategy, substrate inhibition is reduced, high concentration substrate system enzyme efficient catalytic conversion is realized, high concentration seaweed fertilizer is prepared, recycling use of kelp processing wastes and protection of the environment are realized, a kelp industry chain is extended and the kelp processing technology and seaweed fertilizer production level are improved. The preparation method innovates a seaweed fertilizer preparation mode, utilizes kelp production enterprise by-products as raw materials, realizes waste recycling, improves seaweed resource utilization efficiency, protects the environment, reduces a seaweed fertilizer production cost, improves a yield of grapes after application, has strong practicability and can be easily industrialized. The seaweed fertilizer is a pure natural product, does not product pollution, can be degraded, satisfies industrial demands and is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of chemical industry. Background technique [0002] Kelp is a large marine brown algae plant that grows in low-temperature seawater, and belongs to seaweed plants. Kelp Phaeophyceae, Kelpaceae. The sporophytes are large, brown, flat and band-shaped, up to 20m long. It grows in the sea with low water temperature. The northern coast of China and the coasts of Zhejiang and Fujian are extensively cultivated, and its output ranks first in the world. Rich in mineral elements such as alginate and iodine, it can be used as industrial raw materials such as iodine, alginate, and mannitol. Its fronds can be used as medicine. Kelp has many biological functions such as lowering blood fat, lowering blood sugar, regulating immunity, anticoagulation, anti-tumor, detoxifying and anti-oxidation, and is one of the most commonly eaten vegetables. Kelp is processed into various vegetable. [0003] Kelp slag refers to the ...
