Description
Technical field
The present invention relates to Water soluble fertilizer field, be specifically related to the sub-Water soluble fertilizer of a kind of instant micelle with and preparation method thereof.
Background technology
Water soluble fertilizer (WaterSolubleFertilizer) is a kind of multielement compound fertilizer that can be dissolved in water completely, relative to traditional granular compound fertilizer and slow-release fertilizer, due to Water soluble fertilizer have instant, specific absorption is high, instant effect, without residue, use the remarkable advantages such as convenient, obtains swift and violent development.Especially in order to reach, water saving, joint are fertile, the object of saving of labor, the fertigation of water-fertilizer integral, spray in fertilising agriculture production progressively to promote and come.Therefore require more and more higher to Water soluble fertilizer to the rapid dissolution of fertilizer.
Major part fertiliser compounds raw material all has water-soluble, if urea, ammonium sulfate, ammonium chloride, monoammonium phosphate, potassium primary phosphate, diammonium phosphate, potassium sulfate, Repone K, saltpetre, potassium magnesium sulfate, calcium chloride, magnesium sulfate etc. are all the raw materials that Water soluble fertilizer is selected.But in fertigation, use the urea of single compound, phosphate fertilizer and potash fertilizer etc., easily cause the harm that salt density is too high, therefore need Water soluble fertilizer to contain abundant many nutrients.But in the process for preparation of many nutrients; due to different chemical fertilizer raw material potential of hydrogen difference, containing impacts such as crystal water; usually acid-base reaction, replacement(metathesis)reaction, hydrolysis reaction can be there is; intergranular point of contact forms solid and connects brilliant bridge; cause fertilizer agglomeration, deliquescence, even produce insolubles, fertilizer efficiency reduces.As Chinese invention patent CN102010273A discloses a kind of water-soluble chemical fertilizer, consist of: the vitriol of the urea of 20-45 weight part, the phosphate cpd of 20-79 weight part, 20.5-48 weight part, the borax of 0.1-1.5 weight part, seven water ammonium molybdates of 0.1-2 weight part and the polyacrylate compound of 0.5-15 weight part.Directly composite Water soluble fertilizer very easily reacts to each other, thus impact stores, water-soluble and fertilizer efficiency; Chinese invention patent publication number CN102731190A discloses a kind of water-soluble fertilizer, by different components mixture: fulvic acid potassium 0.8-8.4%; Potassium primary phosphate 3.8-12.5%; Water glass 1.9-9.8%; Repone K 1.8-12.6%; Calcium chloride 0.8-3.6%; Copper sulfate 0.025-0.115%; Boric acid 0.05-0.29%; Zinc sulfate 0.06-0.28%; Manganous sulfate 0.03-0.18%; Water 56.5 ~ 75.5%, has prepared the Water soluble fertilizer with compound nutritional.This invention mainly take into account the component of different element, but after so complicated compound mixture, the possibility that causing reacts occurs precipitation is very big, and water glass and calcium ion very easily form Calucium Silicate powder insolubles, thus cause fertilising plugging, and fertilizer efficiency obviously reduces.
In order to avoid the defect of mixture Water soluble fertilizer, by chemosynthesis by the raw material of various nitrogenous, the nutrient such as phosphorus, potassium under the control conditions such as certain temperature, potential of hydrogen, obtain entirely water-soluble compound crystal Water soluble fertilizer through chemical reaction Crystallization Separation such as dissolving, crystallisation by cooling.As Chinese invention patent publication number CN102701824A discloses a kind of production method of macroelement Water soluble fertilizer, the method in a wet process phosphoric acid and ammonia neutralizes, filters, then dissolve in ammonium nitrate, saltpetre, Repone K, through condensing crystal, drying and obtain macroelement Water soluble fertilizer.Compared with the Water soluble fertilizer of producing with simple physical mixture, chemosynthesis Water soluble fertilizer outward appearance is good, lower water-insoluble and foreign matter content can be guaranteed, but the Water soluble fertilizer constituent content obtained is limited, especially cannot by moderate-element configuration wherein, chemosynthesis Water soluble fertilizer, owing to being the even more heterogeneous eutectic reaction of two-phase, three-phase, defines comparatively complicated double salt, solubleness in water is low, dissolution rate slow, and the nutrient of N P and K cannot configure according to demand.In addition, chemosynthesis Water soluble fertilizer is the reactive crystallization again to existing chemical fertilizer raw material, pollute large, cost is high, be difficult in large Tanaka's large-scale promotion.
Moreover if the water-soluble rear plant of Water soluble fertilizer can not absorb in time, the nutrients such as solubility nitrate radical, potassium ion then can permeate the ground, and not only cause fertilizer efficiency to lose, and can pollute underground water.Therefore, along with the application of water-soluble hypertrophy amount, how improving fertilizer efficiency and preventing fertilizer efficiency to run off also becomes the key of lifting Water soluble fertilizer utilization ratio and quality.Because Water soluble fertilizer is not only containing macroelement, also containing moderate-element and trace element, in order to make up the defect of moderate-element and trace element easy deposition invalidation in Water soluble fertilizer, common way is in advance by moderate-element and micro-complexing, as Chinese invention patent publication number CN101544520 discloses a kind of water-soluble solid organic complexation micro-element fertilizer and production method thereof, the soluble salt of micro-Cu, Zn, Fe, B, Mn, Mo, by organic complexing agent EDTA and citric acid, is carried out complex reaction by the method.Not only cost is high for the metal ion of complexing, and EDTA is different from the Acidity Range that metal ion forms stable comple, as Ca2+, Mg2+ will in alkaline ranges, and Zn2+, Ni2+, Cu2+ etc. will in acid ranges, therefore have higher impact to the environment used, adaptability is poor.
According to above-mentioned, by the Water soluble fertilizer of direct mixture because potential of hydrogen between different compound is different, containing impacts such as crystal water, usually acid-base reaction, replacement(metathesis)reaction, hydrolysis reaction can occur, cause being difficult to storing, insolubles increases, fertilizer efficiency reduces; And by the Water soluble fertilizer of chemosynthesis, owing to being complex salt crystal, crystallization condition is harsh, be difficult to the double salt configuring Different Nutrients, and cost is high, solubleness is low, is difficult to large-scale popularization and uses.
