Description
Technical field
The present invention relates to compound manure field, be specifically related to a kind of long-acting modified urea-formaldehyde resin coated slow-release compound manure.
Background technology
In modern agricultural production, the figure of the composite fertilizer that is seen everywhere, it has, and nutrient content is high, minor component is few, utilization rate of fertilizer is high, the advantages such as convenient are used in storage, in promotion higher yield of crops stable yields, play important role.Slow-release compound fertilizer is a kind of important classification in composite fertilizer, the research emphasis of Ye Shi China Growth of Chemical Fertilizer Industry, its slowly-releasing principle is the hydrophobic substance at fertiliser granulates Surface coating thin layer, thus the nutrient of inside is discharged in soil slowly, constantly to farm crop supply nutrient, effectively raise the utilization ratio of fertilizer.But existing slow-release compound fertilizer also exists certain shortcoming, be mainly manifested in nutrients ratio relatively fixing, be difficult to the different demands meeting all kinds of soil and all kinds of crop; Slow release effect is not fully up to expectations, does not mate, thus reduces fertilizer efficiency, affect plant growth with crop growth demand, causes the underproduction reduction of income.
Summary of the invention
The object of the invention is to provide the slow-release compound fertilizer of a kind of low cost, efficient, environmental protection, and to achieve these goals, the technical solution used in the present invention is as follows:
A kind of long-acting modified urea-formaldehyde resin coated slow-release compound manure, it is characterized in that, this fertilizer is made up of the raw material of following weight part: 1250-2000 order diatomite 10-15, ammonium phosphate 10-12, bicarbonate of ammonia 12-15, calcium superphosphate 8-10, flaxseed meal powder 6-8, corn cob 4-6, rapeseed meal 8-10, Chinese medicine slag 4-5, bamboo bits 2-4, agarose 3-5, Tutofusin tris 1-3, disodium ethylene diamine tetraacetate 2-4, urea-formaldehyde resin emulsion 12-15, nilox resin acid potassium 1-2, sodium laurylsulfonate 0.2-0.3, polymeric amide 2-3, Potassium Iodate 1-2, tricalcium phosphate 3-4, Zinc Gluconate 2-3, auxiliary agent 4-5,
Auxiliary agent is made up of the raw material of following weight part: poultry feather 12-15, the sulphuric acid soln 30-35 of 30-40%, Sodium hydroxide q. s, M-Zyme 0.15-0.2, Cuprocitrol 1-2, manganese citrate 1-2, zinc citrate 1-2, medical stone fine powder 20-22, water glass 5-6, preparation method is: first poultry feather is passed through washing, pulverize after high-temperature sterilization, drop in sulphuric acid soln, hydrolysis 15-18h, appropriate sodium hydrate regulator solution pH value is added to 6.5-7.0 in the hydrolyzed solution obtained, and be heated to 50-60 DEG C, add M-Zyme, after enzymolysis 12-15h, add Cuprocitrol, manganese citrate, zinc citrate, after stirring reaction 2-3h, add water glass again, continue to stir 30-40min, finally add medical stone fine powder again, dry after stirring, and grind 40-50min, obtain.
Described urea-formaldehyde resin emulsion solid content is 35%-50%.
Described one long-acting modified urea-formaldehyde resin coated slow-release compound manure, its production stage is as follows:
(1) pulverize after corn cob, rapeseed meal, Chinese medicine slag, the mixing of bamboo bits, then add flaxseed meal powder and appropriate water carries out fermentative processing, fermentation is to for subsequent use after becoming thoroughly decomposed completely;
(2) mix with waiting the water of weight part by diatomite, grinding 20-30min, making diatomite slurry, add Potassium Iodate, Zinc Gluconate, disodium ethylene diamine tetraacetate subsequently, after stirring completely, mixture anhydrates drying, makes diatomite coating material;
(3) agarose, sodium laurylsulfonate are mixed with appropriate deionized water, be heated to 90-100 DEG C, be stirred to material dissolve completely dispersion for subsequent use, subsequently polymeric amide, nilox resin acid potassium are mixed with appropriate dimethylbenzene, be stirred to after it dissolves dispersion completely, add urea-formaldehyde resin emulsion, agarose solution, stir 20-30min with the rotating speed of 3000-3500 rev/min, make slow release coating agent for subsequent use;
(4) other leftover materials are mixed with step (1), (2) gained material; drop into granulation in tablets press; and at slow release coating agent prepared by obtained particle surface spraying process (3), the particle after coating, through warm air drying, room temperature cooling, gets product.
Beneficial effect of the present invention is: formula Raw wide material sources, take full advantage of raw material common in daily life production, reduce growth cost, improve the single fixing phenomenon of conventional composite fertilizer nutrient; Production technique utilizes diatomite adsorb mutually with raw materials such as Potassium Iodate, Zinc Gluconate, disodium ethylene diamine tetraacetate, reach the chelating covered effect to trace element, prevent the too early invalid loss of nutrient; With the slow release coating agent that agarose, polymeric amide and urea-formaldehyde resin emulsion are mixed with, fertility release persistent high efficiency; Composite fertilizer prepared by the present invention utilizes the urea-formaldehyde resin emulsion slow release coating agent of diatomite and modification to be formed dual coated to nutrient, nutrient not easily runs off, fertilizer efficiency is more lasting, can meet needed for omnidistance plant growth, and spoiled soil does not balance, to environment toxicological harmless, effectively planting benefit can be improved.
