Abstract
The present invention discloses a compound-film multielement compound fertilizer with high efficiency and a preparation method thereof. The compound fertilizer contains various medium and trace elements of nitrogen, phosphorus, potassium, sulphur, etc., rare earth, gibberellin, Huolisu, etc.; the preparation method comprises the steps that parts of the components are firstly granulated, and the rest components are dissolved to form a thick liquid which is sprayed on product particles; finally, a film coating agent is used for film coating, and a finished product is obtained by drying and sieving. The product of the present invention has the advantages of strong adaptation, good nutritional quality and obvious yield increasing effect.
Description
The present invention relates to a kind of fertilizer, a kind of multi-element high-effect composite fertilizer of more specifically saying so
Fertilizer commonly used has urea, sulphur ammonium, carbon ammonium, normal superphosphate, Repone K, trace element fertilizer etc., because China is vast in territory, various places soil soil property difference, demand to various elements is also different, and general peasant is for applying fertilizers scientifically, rational application of fertilizers is not familiar with, and not only chemical fertilizer can not get effective utilization, and influences the growth of farm crop and the improvement of soil property.
The objective of the invention is to improve comprehensive nutrition, adapt to wide multiple film multi-element high-effect composite fertilizer.
The objective of the invention is to be achieved through the following technical solutions.
A kind of multiple film multi-element high-effect composite fertilizer is characterized in that by following component (weight) formulated: urea 21kg zinc sulfate 0.5kg MAP or Diammonium phosphate (DAP) 544kg ferrous sulfate 0.5kg potassium sulfate or potassium chloride 417kg ammonium molybdate 0.01kg Cosan 2kg boric acid 2kg rare earth 2kg manganese sulfate 0.5kg copper sulphate 0.5kg coating agent 4kg phosphoric acid 2kg gibberellin 5g Huolisu 3kg
The component prescription of first type product of the present invention is: urea 21kg zinc sulfate 0.5kg MAP or Diammonium phosphate (DAP) 544kg ferrous sulfate 0.5kg potassium sulfate or potassium chloride 417kg ammonium molybdate 0.01kg Cosan 2kg boric acid 2kg rare earth 2kg manganese sulfate 0.5kg copper sulphate 0.5kg coating agent 5kg phosphoric acid 2kg gibberellin 5g Huolisu 3kg
By the product of above-mentioned formulation, nitrogenous 10%, phosphorous 25%, contain potassium 25%, suitable farm crop are used as base manure.
B-mode product component recipe ratio of the present invention: urea 315kg zinc sulfate 0.5kg MAP or Diammonium phosphate (DAP) 360kg ferrous sulfate 0.5kg potassium sulfate or potassium chloride 305kg ammonium molybdate 0.01kg Cosan 3kg boric acid 3kg rare earth 3kg manganese sulfate 0.5kg copper sulphate 0.5kg coating agent 4kg phosphoric acid 2kg gibberellin 5g Huolisu 3kg
By the product that above-mentioned prescription makes, nitrogenous 18%, phosphorus 18%, potassium 18% is fit to the farm crop base and topdresses.
The component prescription of the present invention's third type product is: urea 290kg zinc sulfate 0.5kg MAP or Diammonium phosphate (DAP) 327kg ferrous sulfate 0.5kg potassium sulfate or potassium chloride 300kg ammonium aluminate 0.01kg Cosan 5kg boric acid 8kg rare earth 4kg manganese sulfate 0.5kg copper sulphate 0.5kg coating agent 10kg phosphoric acid 2kg gibberellin 5g Huolisu 2kg
By the product that above-mentioned prescription makes, nitrogenous 15%, phosphorus 15%, potassium 15% is fit to the farm crop base and topdresses, and effect is obvious especially.
The component prescription of fourth type product of the present invention is: urea 250kg zinc sulfate 0.5kg MAP or Diammonium phosphate (DAP) 320kg ferrous sulfate 0.5kg potassium sulfate or potassium chloride 320kg ammonium molybdate 0.01kg Cosan 4kg boric acid 4kg rare earth 4kg manganese sulfate 0.5kg copper sulphate 0.5kg coating agent 8kg phosphatase 24 kg gibberellin 5g Huolisu 4kg
By the product that above-mentioned prescription makes, nitrogenous, phosphorus, potassium are 16%, and nitrogen, phosphorus, potassium element content belong to international type, and crucial part is exactly to increase the essential trace elements of farm crop, adapts to wide.
The preparation method of multiple film urea-S-P-K fertilizer may further comprise the steps:
1, monoammonium phosphate or diammonium phosphate and vitriolate of tartar or Repone K are mixed the batch mixing granulation of prewetting;
2, rare earth, SULPHUR POWDER, Plant hormones regulators,gibberellins, vigor element, copper sulfate, zinc sulfate, ferric sulfate, ammonium molybdate, boric acid, manganous sulfate are added phosphoric acid liquid, suitable quantity of water fully mixes, and is dissolved into the liquid magma, on the spray product particle;
3, the urea powder to the said products granulation wrap up;
4, agent of dryness coating and product particle are mixed, the rotation of rolling makes the agent of dryness coating be wrapped in the particulate appearance;
5, dry, screening.
Second step such as phosphoric acid, water and rare earth additive summation weight ratio is: 2kg: 50kg: 2kg compares with prior art, product of the present invention is applied to farm crop, instant effect, fertilizer efficiency is long, can strengthen the crop photosynthesis effect, promotes the increase of sugar part and VITAMIN, improve output, improve the crop alimentary quality, make the agricultural-food listing early, quality is good.And because product moisture content of the present invention is low, uniform particles, intensity is big, is convenient to artificial, machinery or aircraft big area fertilising operation.
By embodiment the present invention is further described.
Embodiment:
Present embodiment component prescription is: urea 315kg zinc sulfate 0.5kg MAP or Diammonium phosphate (DAP) 360kg ferrous sulfate 0.5kg potassium sulfate or potassium chloride 305kg ammonium molybdate 0.01kg Cosan 3kg boric acid 3kg rare earth 3kg manganese sulfate 0.5kg copper sulphate 0.5kg coating agent 4kg phosphoric acid 2kg gibberellin 5g Huolisu 3kg
It is standby earlier monoammonium phosphate or diammonium phosphate to be processed into powder shape of uniform size; carry out the metering of continuity prescription by micro-processor controlled computer weighing belt respectively with vitriolate of tartar or Repone K; utilizing the belt transfer machine ceaselessly raw material to be sent in the mixing granulator again mixes; simultaneously with rare earth; SULPHUR POWDER; various trace elements; Plant hormones regulators,gibberellins; vigor plain adding phosphoric acid liquid and 100 kg of water fully stir; mixed dissolution becomes the liquid magma; by spraying on the raw material of 10: 100 preset proportion in mixing granulator; the dyanainic friction that ceaselessly revolves by means of mixing granulator; magma is prewetted to raw material; produce viscosity; promote the granulating type; form the viscosity small-particle of φ 1-2 millimeter; utilize conveyor ceaselessly to be sent to rotary drum granulator, the urea powder that will process again directly is transferred in the rotary drum granulator by conveyor by the metering of computer weighing belt sticky particle is wrapped up.The coating agent is by the metering of computer weighing belt, utilizing conveyor to be sent in the coating special machine mixes for the last time with product dry, screening, roll by means of the not stall of rotary drum coating machine is moving, make the coating agent outside the particle of product, form one deck coating gradually.
After warm air drying, screening, chilled product dispatch from the factory after being up to the standards, packing.
