Abstract
The invention relates to a method for co-producing a macroelement and medium element 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 medium elements, heating and stirring the materials until the macroelement fertilizers and the medium elements 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
The present invention relates to a kind of production method utilizing seaweed extracted liquor coproduction a great number of elements moderate-element type Water soluble fertilizer.
Background technology
It is still strong acid, highly basic high temperature and high pressure extraction that the Sargassum liquid main flow extracting method of alga fertilizer is prepared by China, and this extracting mode not only breaks up the effective ingredient in Sargassum, and produces low with safety in utilization.The method utilizing microorganism enzymolysis and extraction also achieves some progress, but owing to enzymolysis time is long, causes that extraction efficiency is too low, it is impossible to meet the market demand.Currently also have method strong acid, highly basic high temperature and high pressure extraction combined with enzymolysis, although saved extraction time, but in strong acid, highly basic high temperature and high pressure extraction process still can to a certain extent to Sargassum in effective ingredient damage.
Summary of the invention
The technical problem to be solved is to provide a kind of production method utilizing seaweed extracted liquor coproduction a great number of elements moderate-element type Water soluble fertilizer.Active component in Sargassum is combined by the method with a great number of elements, moderate-element, can improve crop disease-resistant, resistance, improves crop yield.
In order to solve above-mentioned technical problem, the present invention by the following technical solutions:
A kind of production method utilizing seaweed extracted liquor coproduction a great number of elements moderate-element type Water soluble fertilizer, it is characterised in that according to following
Step carries out:
1), fresh Sargassum is cleaned standby, or dry seaweed be dipped to fresh Sargassum moisture consistent state and clean standby, the alternate products that this step obtains is called A product；
2), water, organic solvent and product A are added separately in reactor, pull an oar in the lump；
3), beaten and added wetting and penetrating agent after slurry, soaked 12～72 hours at 20～45 DEG C；
4), low-temp low-pressure Distillation recovery part organic solvent: vapo(u)rizing temperature is 45～65 DEG C, and distillation pressure is-0.5～-1.2Mpa；
5), filter pressing obtain Sargassum slag and filtrate, described filtrate is seaweed extracted liquor；
6), described seaweed extracted liquor, macroelement fertilizer and moderate-element being mixed, heated and stirred is dissolved completely, and the product after spray drying is and utilizes seaweed extracted liquor coproduction a great number of elements moderate-element type Water soluble fertilizer；
Wherein the mass ratio of A product, water, organic solvent and wetting and penetrating agent is 5～30:10～85:10～85:0.01～0.1;, seaweed extracted liquor, a great number of elements and moderate-element mass ratio be 40～77:20～45:3～20.
Described organic solvent is the two or more of a kind of or arbitrary proportion in ethanol, ether, methanol and ethyl acetate.
Described wetting and penetrating agent is dodecylbenzene sodium sulfonate, sodium lauryl sulphate, alkylphenol polyoxyethylene, sorbitan fatty acid ester-20, sorbitan fatty acid ester-30, sorbitan fatty acid ester-80, polyoxyethylene 20 sorbitan monolaurate-20, polyoxyethylene 20 sorbitan monolaurate-40, polyoxyethylene 20 sorbitan monolaurate-60, polyoxyethylene 20 sorbitan monolaurate-80, fatty alcohol-polyoxyethylene ether-3, fatty alcohol-polyoxyethylene ether-4, fatty alcohol-polyoxyethylene ether-5, fatty alcohol-polyoxyethylene ether-7, fatty alcohol-polyoxyethylene ether-9, fatty alcohol-polyoxyethylene ether-15, fatty alcohol-polyoxyethylene ether-20, a kind of or arbitrary proportion in fatty alcohol-polyoxyethylene ether-23 and dimethyl-silicon wet goods two or more.
Described macroelement fertilizer is the two or more of a kind of or arbitrary proportion in carbamide, ammonium sulfate, PHOSPHORIC ACID TECH.GRADE potassium dihydrogen, PHOSPHORIC ACID TECH.GRADE ammonium dihydrogen, potassium sulfate, potassium chloride and potassium nitrate;Described moderate-element is the two or more of a kind of or arbitrary proportion in Magnesium sulfate heptahydrate, four water-calcium nitrate, ethylenediamine tetraacetic acid disodium magnesium salt, calcium disodium chelate and seven water magnesium nitrates.
Described Sargassum refers to: a kind of or arbitrary proportion in Thallus Laminariae (Thallus Eckloniae), Thallus Porphyrae, Thallus Laminariae (Thallus Eckloniae), opotism and Entermorpha two or more.
In step 5), pressure filter selects filter cloth aperture to be 800～4500 orders.
In step 6), heated and stirred temperature controls at 40～65 DEG C.
The present invention has following Advantageous Effects:
1, in the present invention, Sargassum liquid adopts low temperature, Low Voltage Pure physics to extract, it is ensured that Sargassum effective ingredient is not destroyed.
2, seaweeds appearance has the protecting film of one layer of thickness; prevent external substance from invading; so simple water or organic solvent extract at normal temperatures and pressures can be very slow; the present invention adds wetting and penetrating agent can make the contact area of water and organic solvent and Sargassum increase; rapid solution breaks through described protecting film at normal temperatures and pressures; thus reaching the purpose of rapid extraction, therefore it is more convenient for the application of heavy industrialization.
3, the present invention adopts the extracting method that water and organic solvent combine, and reduces cost than simple organic solvent extraction.
4, the present invention adopts the extracting method that water and organic solvent combine, and adds the compatibility of product, meets the requirement of modern agriculture (water droplet filling).Because such as simple organic solvent extraction, it is possible to extract can not be dissolved completely in water, and product compatibility is poor, it is impossible to meets agricultural modernization (water droplet filling) requirement.
5, a great number of elements, moderate-element effective ingredient in Sargassum is combined by the present invention, can significantly improve that crop is degeneration-resistant, disease resistance.
6, the present invention is entirely water-soluble meets modern agriculture demand.
