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

[0015] 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, distillation and recovery of 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 60:35:5, and after stirring and dissolving completely, it is Product of the present invention.

Embodiment 2

[0017] 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 mix, after stirring and dissolving completely, be product of the prese...

Embodiment 3

[0019] 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. After mixing and stirring and dissolving completely, it is the product of t...

Abstract

The invention relates to a production method for co-producing humic-acid-containing liquid water-soluble fertilizer with seaweed extract. Fresh or dry seaweed is cleaned and added into a reaction kettle containing a mixture of a certain mass of water and organic solvent according to a certain mass ratio, the mixture is stirred at a high speed to be pulped (the dry seaweed needs to be pulped after being soaked to be expanded), then a certain mass of wetting penetrating agent is added, soaking and extracting are performed, part of the organic solvent is recovered through low-temperature low-pressure distilling after soaking is performed for a while at certain temperature, finally, seaweed residues and the seaweed extract are obtained through filter pressing, the seaweed extract and a large amount of element fertilizer and humic-acid-containing organic matter are stirred to be completely dissolved, and the humic-acid-containing liquid water-soluble fertilizer is obtained. The fertilizer and effective components of the seaweed are combined to remarkably improve stress resistance and disease resistance of crops; in addition, the product is completely soluble in water and can meet requirements of modern agriculture.
