Embodiment 1

[0070] Embodiment 1: the production of a kind of seaweed liquid fertilizer

[0071] The steps of the production method are as follows:

[0072] This example uses the kelp obtained after extraction of alginic acid kelp Slag, using the method described in this manual to analyze its kelp The slag contains 2% alginic acid and 38% organic matter based on its dry weight.

[0073] A, according to the weight ratio of kelp slag and water 1:5, said kelp slag is added to the water, fully stirred and mixed;

[0074] B, using concentrated hydrochloric acid to adjust the pH of the mixed solution obtained in step A to 6.8;

[0075] C. Add a compound enzyme to the mixture obtained in step B according to the amount of the compound enzyme being 0.05% of the weight of the kelp slag, and perform enzymatic hydrolysis at a temperature of 32° C. for 24 hours.

[0076] The compound enzyme is 30 parts by weight of cellulase sold by Sukehan (Weifang) Bioengineering Co., Ltd., 30 parts by weight...

Embodiment 2

[0080] Embodiment 2: the production of a kind of seaweed liquid fertilizer

[0081] The steps of the production method are as follows:

[0082] In this example, the residue obtained after extracting alginic acid from Sargassum was used, and the Sargassum residue contained 3% alginic acid and 40% organic matter by dry weight based on the analysis method described in this manual.

[0083] A, according to the weight ratio of sargassum and water 1:1, the sargassum residue is added to the water, fully stirred and mixed;

[0084] B, using concentrated hydrochloric acid to adjust the pH of the mixed solution obtained in step A to 7.2;

[0085] C. Add a compound enzyme to the mixture obtained in step B according to the amount of the compound enzyme being 0.5% of the weight of the sargassum residue, and carry out enzymatic hydrolysis at a temperature of 30° C. for 28 hours.

[0086] The compound enzyme is composed of 10 parts by weight of cellulase sold by Sukehan (Weifang) Bioengine...

Embodiment 3

[0090] Embodiment 3: the production of a kind of seaweed liquid fertilizer

[0091] The steps of the production method are as follows:

[0092] In this example, the residue obtained after extracting mannitol from Ascophyllum nodosum was used, and the Ascophyllum nodosum residue was analyzed by the method described in this manual to contain 2.8% alginic acid and 30% organic matter based on its dry weight.

[0093] A, according to the weight ratio of the Ascophyllum leaf algae residue and water 1:3, add the described Ascophyllum leaf algae residue into the water, fully stir and mix evenly;

[0094] B, using concentrated hydrochloric acid to adjust the pH of the mixed solution obtained in step A to 7.0;

[0095] C. Add a compound enzyme to the mixture obtained in step B according to the amount of the compound enzyme being 0.4% of the weight of the Ascophyllum leaf algae residue, and carry out enzymatic hydrolysis at a temperature of 35° C. for 25 hours.

[0096] The compound en...

Abstract

The invention relates to a method for producing a sargassum liquid fertilizer with sargassum residues. The method comprises the following steps such as mixing of the sargassum residues and water, pH value adjustment of concentrated hydrochloric acid, enzymolysis and separation of complex enzyme and the like. According to the method, the bioactivator and part of nutrient substances remained in the sargassum residues are further extracted for preparing a liquid fertilizer, so that the problem of seawood processing enterprises that the sargassum residues contaminate the environment is solved, the sargassum residues are recycled, the economic benefit of the enterprises is improved, and a new way for comprehensive utilization of sargassum residues is developed. Furthermore, the sargassum liquid fertilizer can improve the photosynthesis speed of vegetable crops, can promote the growth of the vegetables, and improves the output of the vegetable crops obviously.

Description

【Technical field】 [0001] The invention relates to the technical field of fertilizer production. More specifically, the present invention relates to a method for preparing seaweed liquid fertilizer from seaweed residue. 【Background technique】 [0002] my country has a long coastline, a large area of ​​shallow sea, and rich marine resources. There are about 800 species of seaweed that have been recorded, among which large species such as brown algae, red algae, green algae and a small amount of blue algae are economically valuable. So far, seaweed has shown great development potential and economic value in the fields and scope of food, marine medicine, animal feed, organic fertilizer, cosmetics and bioenergy. During the processing and utilization of seaweed, especially after the extraction of mannitol, alginate, iodine and other substances, due to the limitations of the existing process conditions, these components cannot be completely extracted, and the remaining part remain...
