Description
Technical field
The present invention relates to fertilizer processing technique field, particularly relate to a kind of selenium rich strawberry fertilizer and preparation method thereof.
Background technology
Rare earth has Combined Physilogical Effects in plant growing process, both can solve soil trace element and lack problem, promote that again crop root is grown, and promotes Chlorophyll synthesis, improve photosynthesis, promote that crop root is grown, promote Chlorophyll synthesis, improve photosynthesis, promote the activity of enzyme, accelerate material to convert, improve the yield and quality of crop.But without chelating rare earth element, its crop absorption ratio is only a few one thousandth, and effect is excessively poor.Theoretical according to the coordinate bond of complex, this dvielement easily forms stable sequestration thing with some ligands.In fertilizer industry, the U.S. uses more for edetic acid (EDTA) and citric acid, EDTA all has stronger sequestration power to all of transition elements, but its price is high, manufacturing cost is high, and China was the most once advocating use humic acids as intercalating agent, production cost is made to decrease, but humic acids concentration is low, molecular weight is big, sequestration ability.Aminoacid is as ligand, in the case of without photosynthesis, directly participates in the albumen synthesis of body, compared with other intercalating agent, has more significant effect of increasing production to crops, manufacture the key technology that cheap aminoacids complex has become rare earth fertilizer to produce.
Molasses alcohol waste liquid be sugar refinery saccharified residues molasses be raw material, the high concentrated organic wastewater produced during fermenting and producing ethanol, wherein contain more organic substance, such as protein, sugar etc., if not being used and directly processing, not only result in the bigger wasting of resources, and can be because of the expense of load higher increase waste liquid of molasses alcohol.Therefore, molasses alcohol waste liquid is applied in the production of rare earth fertilizer has wide market prospect.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of selenium rich strawberry fertilizer and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of selenium rich strawberry fertilizer, is prepared by the raw materials in:
Molasses alcohol waste liquid 200-210, fallen leaves 5-6, Folium Pini 5-6, mushroom bran 30-31, Maifanitum 5-6, polyoxy starch 7-8, potassium fulvate 0.1-0.2, gibberellins 0.2-0.3, sodium selenite 0.01-0.02, the ethanol 400-410 of 95%, the sodium hydroxide solution 800-810 of 0.5mol/L, the hydrochloric acid solution of 1mol/L is appropriate, the sulfuric acid solution of 50% is appropriate, rare earth oxide 2-3, polyvinyl alcohol 4-5, CNT 0.2-0.3, cycloheptaamylose 0.2-0.3, tea polyphenols 0.1-0.2, microbial germ powder 1-1.2.
The preparation method of described selenium rich strawberry fertilizer, comprises the following steps:
(1) ethanol molasses alcohol waste liquid being added 95% and the sodium hydroxide solution of 0.5mol/L, centrifuging and taking supernatant after reacting 40 minutes, add the hydrochloric acid solution regulation pH to 4 of 1mol/L, sucking filtration, gained precipitation is dried;
(2) being mixed with rare earth oxide by step (1) gained material, the sulfuric acid solution adding 50% reacts 1 hour at 140 DEG C, is subsequently adding polyoxy starch, continues heating, is condensed into paste;
(3) by CNT and cycloheptaamylose mixed grinding 1 hour, then gained material being added appropriate deionized water ultrasonic disperse 2 hours, centrifugation, gained precipitate with deionized water washs 2-3 time, and at 75 DEG C, vacuum drying 24 hours, are ground into powder;
(4) polyvinyl alcohol is added the deionized water of 10 times, at 45 DEG C, constant temperature stirs swelling 3 hours, is then heated to 95 DEG C of stirring to polyvinyl alcohol and is completely dissolved, then adds step (3) gained material, tea polyphenols when temperature is down to 45 DEG C, it is sufficiently stirred for, obtains coating liquid;
(5) it is ground into powder after being calcined 10-15 minute at 700-800 DEG C by Maifanitum, obtains medical stone powder;Fallen leaves, Folium Pini, the regulation of mushroom bran mixing and water adding are reached 55-60% to water content, add microbial germ powder, heap vexed fermentation 25-30 days, the turning of 5-6 days period once, the raw material mixing granulation do not used with step (2) gained material and medical stone powder, above-mentioned technique, gained material is placed in electric drying oven with forced convection, dry to constant weight at 40 DEG C, the most uniformly spray coating liquid, be dried, to obtain final product.
nullThe invention have the advantage that the present invention uses molasses alcohol waste liquid as raw material,It is extracted protein therein,Again by protein and rare earth oxide mixing acid hydrolysis,Rare earth oxide is just added when protein is not hydrolyzed into aminoacid,Peptide bond chelating on the blank side chain with albumen of the track of rare earth ion,Accelerate aminoacid and depart from protein molecule,Aminoacid is shielded by the metal ion added simultaneously,Reduce amino acid whose thermal decomposition,Improve amino acid whose yield,Shorten the response time,Aminoacid improves Fructus Fragariae Ananssae quality with rare earth chelate fertilizer、Reduce persticide residue,And the present invention adds CNT in coating liquid,The mechanical strength of film can be improved,And CNT adds, and cycloheptaamylose is modified improves CNT dispersibility in water,The tea polyphenols added can introduce hydrophobic benzene radicals,Improve the hydrophobicity of film,So that water absorption rate declines,Improve the slow-releasing of film,In addition,The present invention is rich in selenium element,The Se content of the Fructus Fragariae Ananssae cultivated can be improved.
