A kind of disposable employed high-efficiency sustained-release composite basal fertilizer
Technical field
The present invention relates to compound manure field, be specifically related to a kind of disposable employed high-efficiency sustained-release composite basal fertilizer.
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 disposable employed high-efficiency sustained-release composite basal fertilizer, it is characterized in that, this fertilizer is made up of the raw material of following weight part: 1250-2000 order diatomite 10-15, cow dung does 15-18, paddy bran 8-10, urea 20-22, monoammonium phosphate 15-18, calcium superphosphate 8-10, vegetable jelly 2-3, gelatin 1-3, basalt powder 1-2, Repone K 10-12, black earth 6-8, copper sulfate 1-2, zinc sulfate 2-4, Lignum Pini Nodi pine needle 4-5, pre-gelatinized tapioca (flour) 12-15, polyvinyl alcohol 6-8, glycerine 4-5, high-active zinc oxide 0.1-0.2, magnesium sulfate 3-5, Ovum crusta Gallus domesticus 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 disposable employed high-efficiency sustained-release composite basal fertilizer, its production stage is as follows:
(1) pulverize after dry for cow dung, paddy bran, Lignum Pini Nodi pine needle, Ovum crusta Gallus domesticus mixing, add appropriate water, carry 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 copper sulfate, zinc sulfate, magnesium sulfate subsequently, after stirring, mixture anhydrates drying, makes diatomite coating material;
(3) by vegetable jelly, gelatin, polyvinyl alcohol, pre-gelatinized tapioca (flour), glycerine mixing, add in appropriate deionized water, and be heated to 40-60 DEG C, be stirred to mixture to dissolve disperse completely, add high-active zinc oxide more subsequently, continue dispersed with stirring 1-2h, 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 sprinkling step (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, improve the single fixing phenomenon of conventional composite fertilizer nutrient, and production cost is controlled; Medium trace element production technique utilizing diatomite necessary with plant growths such as copper sulfate, zinc sulfate, magnesium sulfate adsorbs mutually, reaches certain covered effect, to prevent the too early invalid loss of nutrient; With the slow release coating agent that the mixed raw materials such as vegetable jelly, gelatin, polyvinyl alcohol, pre-gelatinized tapioca (flour) are standby, have excellent coated slow-release controllability, fertilizer efficiency release is continual and steady, and can be degradable, harmless to soil; Composite fertilizer prepared by the present invention utilizes diatomite and slow release coating agent to be formed dual coated to nutrient, fertility high-efficient and lasting, disposable employedly can meet needed for plant growth, the crop yield of planting and quality all have a certain upgrade, and greatly simplify planting link.
