Description
Technical field
The present invention relates to the fertilizer science technical field relevant, a peptide species humic acids chelating slow-release fertilizer is provided especially with plant nutrition.
Background technology
At present, the farm crop wheat of China, corn, paddy rice, rape, flowers etc. are used the composite fertilizer or the compound fertilizer of single nitrogenous fertilizer or only nitrogenous phosphorus potassium mostly on fertilizer uses.Above-mentioned fertilizer nutrition is single; And do not have slow-release function, use the back and decompose comparatively fast, have only on a small quantity to be absorbed by crop; Utilization rate of fertilizer is only between 25%～35%; All the other nutrients volatilize or are run off by rain-out, thereby cause the pollution of rivers water nutrition, serious harm environment and people health.In addition, above-mentioned fertilizer has very big lethal to seed and young shoot thereof, and the peasant has to repeatedly apply fertilizer.At first need before seeding crops, in soil, apply sowing again behind the base fertilizer, treat that plant growth initial stage and middle and later periods topdress again, not only time-consuming but also effort received the restriction of rainwater simultaneously easily.In order to solve above problem, it is high that people are seeking a kind of fertilizer efficiency always, and only need the disposable slow-release fertilizer that applies.
Summary of the invention
The object of the present invention is to provide a peptide species humic acids chelating slow-release fertilizer,, neither need apply fertilizer to the subsoil in advance, the novel fertilizer of the feature of environmental protection of a kind of saving of work and time that need not again to topdress again to reach when not reducing fertilizer efficiency.
Polypeptide humic acids chelating slow-release fertilizer provided by the invention; It is characterized in that: this slow-release fertilizer by following composition by weight forming 95～110 parts in Repone K, 170～185 parts of monoammonium phosphates, 15～25 parts in bicarbonate of ammonia, 240～260 parts in ammonium sulfate, 260～280 parts in urea, 80～95 parts of humic acidss, 35～45 parts of boron calcium powders, 3～8 parts of Zinc Sulphate Heptahydrates, 5～30 parts of amino acid/11s, 2～5 parts of Sodium Molybdate Dihydrates, 1～5 part of sequestrant, 8～15 parts of polypeptide sustained release dosages, 3～8 parts of coating agent.
Preferred composition proportion is: 100 parts in Repone K, 180 parts of monoammonium phosphates, 20 parts in bicarbonate of ammonia, 250 parts in ammonium sulfate, 275 parts in urea, 90 parts of humic acidss, 40 parts of boron calcium powders, 5 parts of Zinc Sulphate Heptahydrates, 20 parts in amino acid, 3 parts of Sodium Molybdate Dihydrates, 2 parts of sequestrants, 10 parts of polypeptide sustained release dosages, 5 parts of coating agent.
Wherein, the chemical formula of Sodium Molybdate Dihydrate is Na
2MO
4.2H
2O; The preferred alpha amino acid of amino acid; Described sequestrant is a hydroxy ethylene diphosphonic acid; Described polypeptide sustained release dosage is following composition by weight composition: 6～10 parts of Dyhard RU 100s, 3～5 parts of Resorcinol, 44～55 parts in zeolite, 30～50 parts of humic acidss; Described coating agent is following composition by weight composition: sulphur 40-50 part, paraffin 30-40 part, sterilant 6-10 part, additive 5-10 part, and sterilant wherein is a Bordeaux mixture, staple is a copper sulfate, white lime; Additive is a pigment, but in purple, light green, bright red, the light yellow or bright orchid of pigment selection one or more.
In the polypeptide humic acids chelating slow-release fertilizer provided by the invention, sequestrant is a kind of organic substance, it can with some unsettled divalent-metal ion, as: iron, manganese, zinc or the like form stable " inner complex ".All oxidized or easy in water easily be the sedimentary farm crop fertilizer of chemical reaction, usually need make their form stable chelate with sequestrant, be beneficial to the crop absorption utilization.The most significantly example is exactly the protection that ferrous ion often need use sequestrant, just can avoid oxidized or deposited phenomenon takes place, and known iron ion one of must obligato important trace element during to be farm crop breed.Therefore, sequestrant has become in the fertilising control, is worth the title complex of use, and its importance can not be ignored; The polypeptide sustained release dosage helps the slow release of nitrogenous fertilizer, is applicable to that the plant growth stage is between 100～135 days, i.e. the corn of Inner Mongol and the Northeast, paddy rice; One deck sulphur coating that the coating agent is wrapped in urea surface, its coating layer is made up of bag sulphur layer, sealing ply (paraffin-coal tar), face powder layer.In current coated fertilizer, sulfur coated urea is one type of very important coated fertilizer, is particularly useful for a lack of sulfur soil, and it can provide plant-growth needed sulphur nutritive element, can also sterilization, improve soil permeability.
The polypeptide humic acids provided by the invention concrete preparation technology who closes slow-release fertilizer that stings is following:
---Repone K, monoammonium phosphate, bicarbonate of ammonia, ammonium sulfate, urea, humic acids, boron calcium powder, Zinc Sulphate Heptahydrate, amino acid, Sodium Molybdate Dihydrate are mixed stirring in proportion process powder;
---above-mentioned powder sent into the tablets press granulation after, make composite fertilizer through oven dry, cooling, screening;
---sequestrant, polypeptide sustained release dosage, coating agent on the surfaces coated of above-mentioned composite fertilizer; Form the coating of one deck 0.1～0.2mm; The coating material is a permeable material; Can be diffused into inside through permeable membrane through the certain hour water molecules, cause coating to break by means of the inside and outside hydraulic pressure difference, the nutrient of the inside has just discharged then.
Traditional chemical fertilizer executes that nutrient has just discharged in the soil, and the later stage must apply fertilizer again, and is time-consuming, take a lot of work, require great effort.And the slow-release fertilizer among the present invention only needs disposable executing to get final product in the ground, and slow-release fertilizer discharges the nutrient that does not have coating in earlier stage, and the later stage discharges the nutrient of coating, makes crop not take off fertilizer in the phase in whole growth.In addition, added sequestrant among the application, the trace element in its ability chelating soil makes robust plant, and disease resistance is strong.
Polypeptide humic acids chelating slow-release fertilizer provided by the invention; Have following advantage: economy, saving of work and time, preparation method are simple; And the performance with environmental protection, the automatic release of this fertilizer nutrition and the demand of crop match, and fertilizer utilization ratio reaches more than 65%; And fertilizer efficiency period is long, use the back soil in the nutrient survival rate still can reach more than 35% after 3 years.
