Background technology
The nutritive element that provides one or more plant growths essential is provided fertilizer, with the product for agriculture that improves soil property, increases soil fertility, is one of basic substance of agriculture production.Existing fertilizer mostly is chemical fertilizer, and the N. P. K absorption utilization ratio of existing chemical fertilizer is generally lower, thereby so that crop yield improves limitedly, and residual fertilizer also causes soil compaction easily, if the soil that hardens run into that heavy rain washes away also can polluted source.
The present Research of main raw material(s) involved in the present invention is as follows:
Magnetite is the ore of oxide-based mineral magnetite, and main chemical compositions is Fe
3O
4, the tool ferromagnetism, property is crisp, and odorless is tasteless, often originates in magmatite, the metamorphosed rock.
The polyglutamic acid powder is a kind of special negatively charged ion nature polymkeric substance, is the homotype polymeric amide that is consisted of through the acid amides bond with between α-amido and the γ-carboxyl, and from 50,000 to 2 megadaltons of molecular weight do not wait.It is a kind of water-soluble, and biological degradation does not contain the biopolymer of toxicity, can use microbe fermentation method to make.Have superpower wetting ability and water retention capacity; overflow when flooding in soil; can form on plant root hair top layer thin film; the function that not only has protection root hair; the optimal transport platform of nutrient, moisture content and the intimate contact of root hair in the soil especially, dissolving, storage, conveying and absorption that can efficient raising fertilizer.Stop sulfate radical, phosphate radical, oxalate and metallic element to produce precipitating action, make the more effective absorption Soil Phosphorus of crop energy, calcium, magnesium and trace element.Promote the growth of crop root, strengthen disease resistance.Acid, alkali are had excellent surge capability, but active balance soil pH-value, the acid soil property of avoiding life-time service chemical fertilizer to cause.Can be in conjunction with the precipitation toxic heavy metal, to Pb
+ 2, Cu
+ 2, Cd
+ 2, Cr
+ 3, Al
+ 3, As
+ 4Deng toxic heavy metal splendid chelating effect is arranged, prevent that heavy metal from entering food chain.
Vermiculite belongs to silicate, is a kind of natural, nontoxic mineral substance, can expand under high temperature action.Because it has good cationic exchange and adsorptivity, can improve the structure of soil, improve ventilation property and the aquosity of soil, make acid soil become neutral soil; Vermiculite also can play shock absorption, hinders the rapid variation of pH value, fertilizer is slowly discharged in the plant growth medium, and can reduce the harm of excessively using fertilizer that crop is caused; Vermiculite also can provide to crop the elements such as Mn, Cu, Zn of the K, the Mg that self contain, Ca, Fe and trace.
Medical stone, main chemical compositions are inorganic silico-aluminates, are a kind of to biological nontoxic, harmless and have certain bioactive composite minerals.Almost contain the required whole major elements of animals and plants.Can see that by electron microscope a lot of holes are arranged on the medical stone, it is same 20000 times of measuring activated carbon that its surface-area reaches, and pigment, heavy metal, microorganism, chlorpromazine etc. are all had stronger adsorption.When dropping into medical stone in the water, can will decompose after the absorption such as the free chlorine in the water and impurity, organism, miscellaneous bacteria, and then the mineral substance in the make up water.
Summary of the invention
Technical problem to be solved by this invention is, a kind of solid fertilizer is provided, and this solid fertilizer can significantly improve plant to the absorption rate of nitrogen phosphorus potassium, to solve the low variety of issue that causes of existing fertilizer nitrogen phosphorus potassium specific absorption.
Technical scheme of the present invention is as follows:
A kind of solid fertilizer, it is characterized in that it is prepared from by the component of following part by weight: magnetite powder 0.1-0.2 part, polyglutamic acid powder 1-2 part, vermiculite power 15-25 part of activation, medical stone powder 250-350 part of activation, ammonium sulfate 350-430 part, diammonium phosphate or potassium primary phosphate 80-90 part, vitriolate of tartar 120-160 part;
The preparation method of the medical stone powder that wherein activates: medical stone powder is broken to the 200-350 order, is heated to 120 ℃, be incubated 4 hours; Wherein the preparation method of the vermiculite power of activation is with the medical stone powder of activation.
The preparation method of described solid fertilizer, it is characterized in that: after the medical stone powder of vermiculite power, the activation of activation and ammonium sulfate, diammonium phosphate or potassium primary phosphate, vitriolate of tartar are together put into stirrer and stirred, be delivered to granulator granulation, the oven dry fertiliser granulates gets granule fertilizer; Spray magnetite powder and the polyglutamic acid powder that dilutes in the lump through water during granulation.
The another kind of preparation method of described solid fertilizer, it is characterized in that: the vermiculite power of magnetite powder, polyglutamic acid powder, activation, medical stone powder and ammonium sulfate, diammonium phosphate or potassium primary phosphate, the vitriolate of tartar of activation are stirred in stirred pot, get powder fertilizer.
Positively effect of the present invention is:
1, fertilizer of the present invention can discharge hertzian wave for a long time, the warm active cells in deep layer position of electromagnetism wave energy infiltration plant body, thereby improve crop to the absorption rate of nitrogen phosphorus potassium, improve its output, and avoided the low and problem such as the soil compaction that causes, pollution of waterhead of common chemical fertilizer N. P. K absorption utilization ratio; In addition, the warm active cells of hertzian wave also can improve the immunizing power of plant, strengthens that crop is cold-resistant, the ability of fighting drought, disease resistance.
2, the trace element that all contains multiple Promoting plant growth in vermiculite, the medical stone, but when directly using medical stone as mineral manure, some activity and water-soluble lower nutritive ingredient can't be absorbed by crop, after adopting the inventive method with vermiculite, medical stone activation treatment, the emission of its beneficial element can be improved several times to tens times more than.
But 3, the absorption rate of fertilizer Effective Raise nitrogen phosphorus potassium of the present invention, significantly prolong fertilizer efficiency, thereby prevented soil compaction and nutrient element loss.Fertilizer of the present invention is applied to various crop and has all played beyond thought effect of increasing production, and concrete test example is asked for an interview the embodiment part.
