In the presence of magnetic agitation, in vinyon beaker, with the KOH solution of 2.5M 125ml with per minute The speed of 10ml titrates the Fe (NO of 0.5M 30ml3)3Solution, after KOH has all been titrated, the suspension that will be obtained is placed on 60 DEG C Aging 100 hours of constant temperature in baking oven;After being cooled to room temperature, the yellow mercury oxide for obtaining by 8000rpm/min centrifugations, Then precipitated with deionized water rinsing, the circulating repetition 6 times, 40 DEG C of dryings of the precipitation that will finally obtain, grinding can be received Rice goethite.The nanometer goethite of synthesis observes its pattern and particle chi with 200kV Flied emissions transmission electron microscope (TEM) Very little size, INSTRUMENT MODEL is JEM-2100F.Nanometer goethite is made suspension first, ultrasonic disperse 10min drops in suspension Continue dropwise addition on copper mesh, after drying to be repeated 3 times, then analyzed on TEM.As shown in figure 1, the nanometer goethite crystalline of synthesis Shape is all needle-like, and mean breadth shows that the mineral for synthesizing have good crystallization, meet in 14nm, the appearance of electronic diffraction circle The requirement of nano particle.The surface functional group of nanometer goethite is analyzed with NicoletiS10 Fourier infrared spectrographs, is such as schemed Shown in 2,891,795,638 and 3380cm-1Peak represent the vibration of Fe-OH and Fe-O, they can be with the hydrophobic table of wax coat Face is affine, extends the foliar fertilizer holdup time.
2. the preparation of amino acid hydrolyticsolution
In 80 DEG C of water-bath, lean pork stripping and slicing is put into triangular flask, is subsequently adding concentrated sulfuric acid hydrolysis, treat hydrolysis knot Triangular flask is taken out after beam, is imported in Plastic Drum after being cooled to room temperature, with the pH of KOH neutralizing hydrolysis liquid, it is finally reached 1, Then hydrolyzate is saved backup, the content of the amino acid for finally giving is 34.00g/L.
3. the preparation of the nanometer goethite-composite foliage fertilizer of amino-acid of different nanometer goethite additions
It is each in three vinyon beakers to add 1L amino acid hydrolyticsolutions, be added thereto to respectively 0.1g, 0.5g and The nanometer goethite of 1g, then excusing from death dispersion 20min, shaking table vibration 30min, that is, obtain the compound leaf of nanoneedle iron ore-amino acid Leaven.500 times are diluted when using.
4. the growth-promoting experiment of pair tomato
The pot experiment of tomato growth-promoting is in Jiangsu Province's solid organic castoff resource Hi-Tech Key Laboratory temperature Carried out in the greenhouse of room, experiment sets 8 treatment, and scheme is as follows:(1) CK, to spray deionized water as control;(2) G1, by 10ml/ Strain sprays the nanometer goethite suspension of the 0.1g/L of 500 times of dilution on the blade face of tomato;(3) G2, dilution is sprayed by 10ml/ plants The nanometer goethite suspension of 500 times of 0.5g/L is on the blade face of tomato;(4) G3, the 1g/ for diluting 500 times is sprayed by 10ml/ plants The nanometer goethite suspension of L is on the blade face of tomato;(5) A, by 10ml/ plants spray dilution 500 times amino acid hydrolyticsolution in kind On the blade face of eggplant;(6) AG1, is the acid hydrolysis of 0.1g/L by the 10ml/ plants of nanometer goethite concentration for spraying 500 times of dilution Liquid is on the blade face of tomato;(7) AG2, is the amino of 0.5g/L by the 10ml/ plants of nanometer goethite concentration for spraying 500 times of dilution Acid hydrolysis liquid is on the blade face of tomato;(8) AG3, is 1g/L's by the 10ml/ plants of nanometer goethite concentration for spraying 500 times of dilution Amino acid hydrolyticsolution is on the blade face of tomato.Each 10 repetition for the treatment of, soil 2kg is filled per basin, uses the nitrogen of equivalent, phosphorus, potassium Fertilizer.After after seedling replanting 2 weeks, start to spray foliar fertilizer, sprayed once every 6 days, after being repeated 5 times, determine the strain of tomato plant High, stem is thick, overground part dry weight and underground part dry weight.
As shown in figure 3, nanometer goethite concentration is significantly higher than for the fertilizer efficiency of the nanometer goethite-amino acid foliage fertilizer of 1g/L CK and singly apply the A treatment of amino acid foliage fertilizer;The addition concentration effect most preferably 1g/L of nanometer goethite, addition is During 0.1g/L and 0.5g/L, growth-promoting DeGrain.By scheme (2), (3), (4) nanometer goethite independent spraying test, Its result shows that the growth individually using nanometer goethite on tomato plant does not influence, with the CK treatment no significance differences of contrast It is different.
It is recognised that the illustrative embodiments that examples detailed above is used only for explanation inventive principle, but it is of the invention This is not limited only to, those skilled in the art can make various improvement and change in the case where real situation of the present invention is not departed from, these Improve and change falls within protection scope of the present invention.
