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, distillation recovery part of the organic solvent at a temperature of 45°C, the filter press uses a 1000-mesh filter cloth for pressure filtration, and the resulting filtrate, urea, industrial grade potassium dihydrogen phosphate and disodium zinc edetate are in a mass ratio of 50:31 :16:3 mixing, heating to 55°C, stirring and dissolving, spray drying, and the dried product 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. Add alkylphenol polyoxyethylene ether and polyoxyethylene sorbitan monolaurate-60 as wetting and penetrating agent, soaked dried kelp, dried Enteromorpha, water, alcohol, ether, alkylphenol polyoxyethylene The mass ratio between vinyl ether and polyoxyethylene sorbitan monolaurate-60 is 4:2:25:60.97:8:0.01:0.02, soaked at 25°C for 60 hours, at a negative pressure of 0.7Mpa, the temperature Part of the organic solvent was recovered by distillation at 50°C, and the filter press was filtered with a 1200-mesh filter cloth. Disodium ferrous diamine tetraacetate is mixed according to the mass ratio of 51:20:15:10:2:2, heated to 45°C, stirred and dissolved, spray-dried, and the dried product is the product of the present invention. ...

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 of the organic solvent is recovered by distillation, and the filter press uses a 1400-mesh filter cloth for pressure filtration. The resulting filtrate, urea, industrial grade potassium dihydrogen phosphate, disodium zinc edetate and disodium manganese edetate are in accordance with the quality Mix at a ratio of 51:30:15:2:2, heat to 50°C, stir and dissolve co...

Abstract

The invention relates to a production method for co-production of a macroelement and microelement type water-soluble fertilizer by utilizing seaweed extracts. Fresh seaweed or dry seaweed is washed and added into a reaction kettle containing mixture of water of a certain mass and an organic solvent according to a certain mass ratio, high-speed stirring and pulping are performed (dry kelp needs to be pulped after being soaked and expanded), a wetting penetrating agent of a certain mass is added after the pulping, and soaking and extraction are performed; after the soaking for a period of time at a certain temperature, part of organic solvent is recycled through low-temperature low-pressure distillation, seaweed residue and the seaweed extracts are obtained finally through a filter pressing mode, the seaweed extracts and macroelement fertilizer and microelements are heated and stirred to be dissolved completely and undergo spray drying, and the obtained product is the product. The product combines fertilizer and effective ingredients of seaweed and has a remarkable effect on improving crop stress resistance and disease resistance; in addition, the product is all water-soluble and can meet the requirements on modern agriculture.
