Problems solved by technology

[0002] The mainstream extraction method of seaweed liquid for preparing seaweed fertilizer in my country is still strong acid and strong alkali high temperature and high pressure extraction. This extraction method not only destroys the active ingredients in seaweed, but also has low production and use safety.
The method of using microbial enzymatic hydrolysis extraction has also made some progress, but due to the long enzymatic hydrolysis time, the extraction efficiency is too low and cannot meet the market demand
At present, there is also a method of combining high-temperature and high-pressure extraction with strong acid and strong alkali with enzymatic hydrolysis. Although the extraction time is saved, the active ingredients in seaweed will still be damaged to a certain extent during the high-temperature and high-pressure extraction process of strong acid and strong alkali.

Embodiment 1

[0028] Add the washed fresh Enteromorpha enteromorpha into a reaction kettle filled with water and alcohol for beating. After beating, add sorbitan fatty acid ester-20 and alkylphenol polyoxyethylene ether as a wetting and penetrating agent, Fresh Enteromorpha, water, alcohol, alkylphenol polyoxyethylene ether, and sorbitan fatty acid ester-20 are in a mass ratio of 20:15:64.96:0.02:0.02, soaked at 20°C for 72 hours, and placed in a negative pressure of 0.5 Mpa, distill and recover part of the organic solvent at a temperature of 45°C. The filter press uses a 1000-mesh filter cloth for pressure filtration. The obtained filtrate, urea and potassium humate are mixed according to the mass ratio of 50:45:5, heated to 40°C and stirred to dissolve completely. Finally, spray drying, the product after drying is the product of the present invention.

Embodiment 2

[0030] Mix the washed dried kelp and dried Enteromorpha into dry seaweed in proportion, soak until the water content of fresh kelp is consistent with that of fresh kelp, add it to a reaction kettle filled with water, alcohol and ether, and beat together. Alkylphenol ethoxylates and polyoxyethylene sorbitan monolaurate-60 are added as wetting penetrating agents, soaked dried kelp, enteromorpha, water, alcohol, ether, alkylphenol polyoxyethylene The mass ratio between ether and polyoxyethylene sorbitan monolaurate-60 is 4:2:25:60.97:8:0.01:0.02, soaked at 25°C for 60 hours, under negative pressure 0.7Mpa, temperature 50 Part of the organic solvent is distilled and recovered at ℃, and the filter press uses a 1200-mesh filter cloth for pressure filtration. The obtained filtrate, urea, industrial grade ammonium dihydrogen phosphate, potassium humate and potassium fulvic acid are in a mass ratio of 65:20:10:3 : 2 mixed, after being heated to 45 ℃ of stirring and dissolving completel...

Embodiment 3

[0032] Add the washed fresh kelp into a reaction kettle filled with water, alcohol, ethyl acetate and ether for beating, and add sodium dodecylbenzenesulfonate and alkylphenol polystyrene as a wetting and penetrating agent after beating. Oxyethylene ether, sorbitan fatty acid ester-60 and simethicone oil, fresh kelp, water, alcohol, ethyl acetate, ether, sodium dodecylbenzenesulfonate, alkylphenol polyoxyethylene ether, lost Sorbitan fatty acid ester-60 and simethicone oil according to the mass ratio of 18:18:20:15:28.96:0.01:0.01:0.01:0.01, soak at 30°C for 46 hours, under negative pressure 1.0Mpa, temperature 55°C Part organic solvent is reclaimed under distillation, and the filter press adopts 1400 mesh filter cloths to carry out pressure filtration, and gained filtrate, urea, technical grade potassium dihydrogen phosphate, nitrohumic acid and sodium humate are according to mass ratio 60:25:10:2: 3. Mix, heat to 50°C, stir and dissolve completely, then spray dry, and the dr...

Abstract

The invention relates to a method for co-producing a humic acid containing water-soluble fertilizer by utilizing a seaweed extract. The method comprises the following steps: washing fresh or dried seaweeds, adding the fresh or dried seaweeds to a reaction kettle containing a mixture of a certain mass of water and organic solvents according to a certain mass ratio, stirring the materials at a high speed for pulping (the dried seaweeds need to be soaked to swell and then are pulped), adding a certain mass of wetting and penetrating agents after pulping, soaking and extracting, recovering part of the organic solvents through low temperature and low pressure distillation after soaking at a certain temperature for a period of time, finally obtaining seaweed residues and the seaweed extract through filter pressing, mixing the seaweed extract with macroelement fertilizers and humic acid containing organic matters, heating and stirring the materials until the macroelement fertilizers and the humic acid containing organic matters are completely dissolved and carrying out spray drying, thus obtaining the product. The method has the beneficial technical effects that combining the fertilizers with active ingredients of the seaweeds, the product has obvious effects on improvement of the stress resistance and disease resistance of crops; and besides, being fully water-soluble, the product can meet the requirements of modern agriculture.

Description

technical field [0001] The invention relates to a production method for jointly producing humic acid-containing water-soluble fertilizer by using seaweed extract.
