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 modified acroleic acid coating Synergistic 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, castor shell 5-6, rapeseed meal 10-12, Chinese medicine slag 4-5, bamboo bits 5-6, Zinc Gluconate 2-4, ferrous sulfate 3-4, Sulfothiorine 2-3, ethylene glycol dimethacrylate 6-8, corn bran 10-12, Repone K 8-10, urea 12-15, diammonium phosphate 20-25, vinasse 8-10, sodium lauryl sulphate 1-2, vinylformic acid 12-15, become thoroughly decomposed ight soil 12-15, analysis for soybean powder 2-3, zinc acetate 2-4, sodium acetate 1-2, 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 a kind of modified acroleic acid coating Synergistic slow release compound manure, its production stage is as follows:
(1) castor shell, rapeseed meal, Chinese medicine slag, corn bran, vinasse are mixed rear pulverizing, consider to be worth doing with bamboo, analysis for soybean powder mixes, add appropriate water and carry out fermentative processing, for subsequent use to material after becoming thoroughly decomposed completely;
(2) mixed with waiting water of weight part by diatomite, grinding 20-30min, makes diatomite slurry, add Zinc Gluconate, ferrous sulfate, zinc acetate subsequently, mix and blend 20-30min, stirs and terminates rear mixture and to anhydrate drying, make diatomite coating material;
(3) vinylformic acid being mixed with waiting the deionized water of weight part, adding sodium lauryl sulphate, be stirred to after material dissolves dispersion completely, heated solution is to 60-80 DEG C, add ethylene glycol dimethacrylate, sodium acetate again, abundant stirring reaction 1.5-2h, makes 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 production cost, improve the single fixing phenomenon of conventional composite fertilizer nutrient; Production technique utilizes diatomite have the nutrient of promoter action to adsorb mutually with Zinc Gluconate, ferrous sulfate, zinc acetate etc. to plant growth, carry out effectively coated, prevent the invalid release of nutrient and loss; With the slow release coating agent that the raw material reaction such as vinylformic acid, ethylene glycol dimethacrylate is made, there is excellent coated slow-release controllability, make crop in growth cycle, absorb enough nutrients; The slow release coating agent that composite fertilizer prepared by the present invention utilizes diatomite and modified acroleic acid to prepare is formed dual coated to nutrient, make fertilizer efficiency more lasting, improve the utilization ratio of fertilizer, Crop nutrient is more abundant, thus effectively raises the seed output and quality of crop.

(2) mixed with waiting water of weight part by diatomite, grinding 20-30min, makes diatomite slurry, add Zinc Gluconate, ferrous sulfate, zinc acetate subsequently, mix and blend 20-30min, stirs and terminates rear mixture and to anhydrate drying, make diatomite coating material;
(3) vinylformic acid being mixed with waiting the deionized water of weight part, adding sodium lauryl sulphate, be stirred to after material dissolves dispersion completely, heated solution is to 60-80 DEG C, add ethylene glycol dimethacrylate, sodium acetate again, abundant stirring reaction 1.5-2h, makes 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.
