Description
Technical field
The invention belongs to the chemurgy technical field.
Background technology
At present, " nitrogen phosphorus potassium " two elements or three element compound fertilizer both at home and abroad, it is the product that grows up in the 60 to 70's of twentieth century, technology falls behind, the nutritive element dullness, this formula fertilizer of life-time service can make crops " partial eclipse " and easily worm is easily sick, causes grain yield to be in the situation of stagnation for a long time.Moreover because a large amount of phosphorus potassium that use in the fertilizer formula, it is general that China's phosphorus ore and potassium ore resources are burst day by day, on average satisfies dimensions of market every year less than 15%.Raw material in great shortage progressively strengthens the cost of production composite fertilizer, reduced the original just very meagre profit of manufacturer on the one hand, also increased the weight of the peasant economy burden on the other hand indirectly.For alleviating this situation; promote agricultural development; fundamentally alleviate the very heavy and catastrophic pressure that the exploitation of Mineral resources excess load brings; the protection Mineral resources are rationally utilized; maintaining ecological balance; improve grain yield, just must seek a kind of economical and practical, reserves abundant, the significant chemical element of fertilizer efficiency replaces the effect of phosphorus potassium element in fertilizer formula.For this reason, in recent decades, during both at home and abroad scientist is in continuous exploration always and strives to find.For example, countries such as the relatively advanced U.S. of foreign agriculture science and technology, Japan, Russia and Germany, from their invention disclosed patent, though the new composite fertilizer prescription of various organic or inorganic things is arranged, but till now, also there is not one to relate to the prescription that nano material and sea-water extract fertilizer (MgO) are used in composite fertilizer.Fill a prescription from the existing domestic and international patent new fertilizer of announcing, though to fertilizer quality, nutritive element has certain improvement, and its compositional refinements amplitude is little, so effect of fertilizer is also all not obvious.
Prior art and present technique further contrast are as follows:
The diammonium phosphate produced in USA and the diammonium phosphate of domestic production are present universally recognized high-quality two element compound fertilizers.Its composition (1) is the H by 12-80% (content calculates with P=A+B=100%)
2PO
4(2) close granulation in the reaction of the liquefied ammonia of 90-98% (content calculates with H=A+B=100%) and make, its effective constituent P that mainly contains is 45%, and containing N is 18%, compares with present technique, and the chemical element of wherein mainly filling a prescription is widely different.
Also have Russia, Canada and the plain composite fertilizer of domestic high concentration ternary of generally producing, its component thing (1) is ammonium chloride or the ammonium sulfate by 20-60% (content calculates with A+B=100%); (2) calcium superphosphate of 12-20% (content calculates with A+B=100%) or high density H
2PO
4(referring to that P content is about 90%), form by spraying or disk granulation.Its compound composition is 15% (total content P, P, the K=A+B+C=45%) that N, P, K respectively account for total content, compare with present technique, wherein N content is starkly lower than prescription of the present invention, wherein P, K content are higher than 1-2 of the present invention doubly, and it does not contain nano material and MgO and other trace element, with component thing of the present invention different resolutely differences is arranged.
Patent CN1036004A discloses " making method of the plain composite fertilizer of a kind of rare earth multicomponent ".Its component thing is: phosphoric acid dichloro potassium 40% (calculating with weight), urea 8% (weight meter), boric acid 8% (weight meter), zinc sulfate 8% (weight meter), sal epsom 8% (weight meter), manganous sulfate 7% (weight meter).Copper sulfate 6% (weight meter), ferrous ammonium sulphate 5% (weight meter), rare earth nitrate 0.30% (weight meter), multitudinous sugared 0.80% (weight meter), bran propylhomoserin 0.47% (weight meter), citric acid 2% (weight meter), vitaminB10 .4% (weight meter), Mierocrystalline cellulose 1% (weight meter), casing coupling peace 0.02% (weight meter), naphthylacetic acid 0.01% (weight meter), prescription remove biphosphate potassium, sal epsom has a bit similar to the present invention, but do not have what essence to link to each other.What use in the present invention prescription is nanometer potassium primary phosphate and nanometer sal epsom, with it in essence difference is arranged.Moreover, its employed rare earth base mateiral, composition and performance from the trace element of originating, contain, be as different as light from darkness with utilization nano material and sea-water extract fertilizer (MgO) among the present invention, and it only is used as rare earth, and trace element uses, and the present invention extracts nano material from rare earth, and is used as that the major ingredient of component thing in the composite fertilizer uses, and this point is apparent in view.
In addition, patent CN1082534A discloses with " manufacture method of the multiple-element long active composite fertilizer of k extracted from sea water with kieselguhr ".It is to add old halogen to isolate sal amarum in bittern, analyzes carnallitite from old halogen, dissolves the carnallitite powder then, with potassium element in the diatomite adsorption decomposed solution, and preparation nitrogen phosphorus, production composite fertilizer.Its production method is primarily aimed at potassium, and extracts MgO and mixture among the present invention from mineral fertilizers obtained from sea water (bittern), replaces the effect of phosphorus potassium, produces nano super composite fertilizer, and the production technique difference is arranged, and extracts component thing difference.In addition, its patent formulation is not identical with the present invention's prescription yet.
As for number of patent application 94108836.7 " is carrier is made compound iodine fertilizer with marine alga iodine method with diatomite ", its method mainly is based on diatomite, add marine alga iodine, produce it and contain compound iodine fertilizer, though have near local with the present invention, but with the present invention based on nano material, be the super composite fertilizer that main body is produced multielement, full nutrition, high fertilizer efficiency with compounding substances such as MgO in the sea-water extract fertilizer, all not from production technique to extraction component thing.
Patent CN117286A discloses " a kind of silicon-calcium-magnesium compound fertilizer ", and its main production raw material is waste steel slag 85-92 part, potassium element 8-15 part, wherein silicone content is 13.5 ± %, Mg content 12 ± %, phosphorus content 8 ± 0.5%, potassium content 10-12%, moisture content＜0.5%, pH value 12.It and the present invention have very big difference from the component thing of filling a prescription.
At present, there is not a family to adopt nano material production and manufacturing composite fertilizer both at home and abroad.Fertilizer element lacks inherent sfgd., and the fertilizer nutritive element is less, concentrates fertilizer time of releasing, release rate is fast, discharges to run off manyly, and the fertilizer efficiency utilization ratio is low, causes crops " hour be unable to finish, grow up eat less than ".A large amount of nitrogen phosphorus potassium and nutrient loss have promptly been wasted resource, man power and material among space and rivers and lakes, polluted air and environment again, also cause the crops underproduction simultaneously.
Summary of the invention
