Description
Technical field
The present invention relates to a kind of organic selenium-enriched liquid fertilizer and preparation method thereof, especially relate to a kind of amino acid whose selenium-enriched liquid fertilizer of organic selenizing and preparation method thereof that contains.
Background technology
The selenium element is decided to be the third-largest micronutrient health care element behind iodine, zinc by the World Health Organization and Chinese Medical Association.Medical research shows, many-sided functions such as that selenium has in human body is anti-oxidant, prevention canceration, toxin expelling, raising immunizing power have unique effect at aspects such as prophylaxis of tumours, cardiovascular and cerebrovascular diseases, diabetes, upper respiratory tract infection.In addition, the selenium element still is a lot of heavy metals as the toxinicide of lead, mercury, arsenic and nitrite, enjoys the good reputation of " anticancer king " and " natural toxinicide ".
Human body mainly comes as in the middle of the food the picked-up of selenium element, if (the 50-100 microgram is recommended to take in by NAS to take in the 50-200 microgram every day, the 50-400 microgram is recommended to take in by China Preventive Medicial Science Institute), just can bring into play above-mentioned effect, and China has the area more than 70% to lack selenium at present, the serious selenium that lacks in area more than 1/3rd is wherein arranged, and selenium content is very few in the common food, and daily food can't guarantee to take in every day the 50-200 microgram.
Farm crop are mended selenium, can improve the nutritional status of crop itself on the one hand, promote the growth of crop, improve output, can increase simultaneously the content of selenium element in the corresponding agricultural-food again, provide safe selenium-enriched food, can be described as a big exploit behave of current agriculture production to the mankind.
Farm crop are mended selenium, key is the production method and the application process of selenium fertilizer, it is the heat subject of studying now, existing selenium fertilizer production method Chinese patent literature shows nearly tens, summary is got up, the one, in fertilizer, directly add the mineral compound of selenium, as Chinese patent application number is 01113654.5 disclosed selenium-rich amino acid and production method thereof, directly add Sodium Selenite, this method can improve the selenium content of farm crop fruit, but there is great security risk in Sodium Selenite toxicity height in production and use, be exactly that inorganic selenium is reduced into easily and can not absorbs or the difficult material that absorbs in addition, cause specific absorption low; Two is exactly physics interpolation nanometer selenium in plant nutrition liquid, as No. 200410023389.8 disclosed fruits and vegetables class nanometer selenium nutrition regulating agents of Chinese patent, its shortcoming is that product can not long storage time, prolongation along with the product shelf-time, the nanometer selenium surface is because of electrostatic interaction, nanometer selenium is assembled and is assembled piece, thereby has lost the nano active of nanometer selenium, does not reach the crop assimilation effect of expection.
Summary of the invention
The object of the present invention is to provide a kind of production safe in utilization, the shelf lives is long, organic selenium-enriched liquid fertilizer of good absorbing effect and preparation method thereof.
Technical scheme of the present invention is:
Each component concentration of the present invention's organic selenium-enriched liquid fertilizer is: total animal ceratin hydrolysis amino acid 〉=10wt%, in selenium organic selenium total content 0.1-3wt%, tensio-active agent 2-3wt%, the required trace element zinc 〉=1.0wt% of plant, boron 〉=1.0wt%, Yu Weishui.
Described tensio-active agent can be polyoxyethylene nonylphenol ether, and the existence form of organic selenium is organic selenizing amino acid.
The preparation method of the present invention's organic selenium-enriched liquid fertilizer may further comprise the steps:: (1) raw material is handled: the screening of the dust impurity in the animal raw Keratin sulfate (for example people's hair wastes, poultry feather, pig hair tankage etc.) is removed, keep dry; (2) hydrolysis: animal ceratin is dropped into hydrolytic decomposition pot, according to the weight ratio of animal ceratin and water is that the ratio of 1:0.8-1.2 adds water, and adding strong acid (as sulfuric acid, hydrochloric acid etc.), regulating the pH value is 3.0 ± 0.5, be heated to 100-110 ℃, hydrolysis 10-12 hours interrupts the peptide chain of animal ceratin, and amino acid is free in the water; (3) dilute: hydrolyzed solution thin up to the total amino acid content that with total amino acid content after the hydrolysis is 26～32wt% is 17～19wt%, mixes; (4) decoloration and deodorization de-oiling fat and insoluble substance: the hydrolyzed solution after will diluting is put into bleacher, adds the activated carbon that is equivalent to hydrolyzed solution weight 5-8%, removes pigment, stink, grease and insoluble substance; (5) filter: the hydrolyzed solution after the decolouring is through pressure filter filtering activated carbon; (6) add selenium: in amino acid hydrolyticsolution, add the simple substance nanometer selenium powder that is equivalent to amino acid hydrolyticsolution weight 0.2-6wt%, be warming up to 55-60 ℃, be incubated 3-5 hour, and stir with 90-120r/Min speed, nanometer selenium and amino acid reaction generate selenium and amino acid whose organic compound, promptly organic selenizing amino acid; (7) neutralization: will contain the amino acid whose solution of organic selenizing and put into neutralization tank, and add neutralizing agent (for example caustic soda or soda ash solution etc.), adjusting the pH value of solution value is 5-6; (8) dilution dissolving: thin up is to each component concentration value: total amino acid 〉=10wt% of regulation in neutralizer, in selenium organic selenium total content 0.1-3wt%, add the tensio-active agent that is equivalent to total solution weight 2-3wt% simultaneously, and required convention amount trace element zinc and the boron of adding plant, make the zinc 〉=1.0wt% in the solution, boron 〉=2.0%; (9) filter once more, check then, measure, pack.
The present invention's organic selenium-enriched liquid fertilizer belongs to a kind of organic selenium-enriched liquid fertilizer made from biological synthesis process that contains various nutrient elements such as organic selenizing amino acid, zinc, boron, produce safe in utilization, can improve the assimilated efficiency of farm crop to selenium, improve disease-resistant worm, the fighting drought of farm crop, the ability of volume increase, have and mend selenium, improve the farm crop fruit quality, reduce the effect of heavy metal toxicity; Shelf lives can reach 3 years, never degenerates.
