A kind of dual-sustained-release compound fertilizer containing Oleum Fructus Bruceae
Technical field
The present invention relates to compound fertilizer field, be specifically related to a kind of dual-sustained-release compound fertilizer containing Oleum Fructus Bruceae.
Background technology
In modern agricultural production, the figure of the compound fertilizer that is seen everywhere, it has, and nutrient content is high, accessory ingredient is few, utilization rate of fertilizer is high, the advantages such as convenient are used in storage, plays important role in terms of promoting higher yield of crops stable yields.Slow-release compound fertilizer is a kind of important classification in compound fertilizer, the research emphasis of Ye Shi China Growth of Chemical Fertilizer Industry, its slow release principle is the hydrophobic substance at fertiliser granulates Surface coating thin layer, thus internal nutrient is discharged in soil slowly, constantly supply nutrient to crops, effectively raise the utilization rate of fertilizer.But existing slow-release compound fertilizer there is also certain shortcoming, it is mainly manifested in nutrients ratio and is relatively fixed, be difficult to meet the different demands of all kinds of soil and all kinds of crop;Slow release effect is not fully up to expectations, does not mates with crop growth demand, thus reduces fertilizer efficiency, affects plant growth, causes the underproduction reduction of income.
Summary of the invention
Present invention aim at providing a kind of low cost, efficient, the slow-release compound fertilizer of environmental protection, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of dual-sustained-release compound fertilizer containing Oleum Fructus Bruceae, it is characterized in that, this fertilizer is made up of the raw material of following weight portion: 1250-2000 mesh kieselguhr 10-15, bagasse 8-9, humic acids 10-12, zinc citrate 4-6, potassium carbonate 18-20, carbamide 20-22, Pericarpium Trichosanthis 6-8, residue of monosodium glutamate 4-6, broken Semen Gossypii 3-5, grass meal 5-6, peat composed of rotten mosses 8-9, Pericarpium Granati 1-2, waste beer yeast slurry 10-12, pig manure 8-10, polyvinyl alcohol 10-12, dioctyl sodium sulfosuccinate 1-2, Carboxymethyl cellulose sodium 3-5, Oleum Fructus Bruceae 1-2, medical stone powder 2-4, poly-silicic acid iron sulfate 6-8, auxiliary agent 4-5;Described auxiliary agent is prepared by the raw materials in: vermiculite power 14-15, Borax 2-3, calcium amino acid chelate 1-2, manganese citrate 1-2, zinc citrate 1-2, methyl methacrylate 4-6, bacillus subtilis viable bacteria powder 2-3, organic chelated titanium 0.1-0.15, Ammonium persulfate. 1-2, water is appropriate, preparation method is: by vermiculite power, Borax is incorporated in water, stir, add organic chelated titanium, zinc citrate, methyl methacrylate, it is heated to 70-80 DEG C, stirring reaction 30-45 minute, it is cooled to 20-35 DEG C, add other residual components, stirring reaction 20-30 minute, cooling, drying.
Described a kind of dual-sustained-release compound fertilizer containing Oleum Fructus Bruceae, its production stage is as follows:
(1) after mixing homogeneously with residue of monosodium glutamate, grass meal after bagasse, Pericarpium Trichosanthis, broken Semen Gossypii, Pericarpium Granati being pulverized, adding appropriate water, at anaerobism normal temperature condition bottom fermentation 4-5d, fermentation material is standby;
(2) kieselguhr is mixed with the water waiting weight portion, grind 20-30min, make kieselguhr slurry, poly-silicic acid iron sulfate is added with stirring slurry limit, back, poly-silicic acid iron sulfate adds medical stone powder after adding, and stirs 10-15min, adds humic acids, after stirring, mixed material anhydrates dry, makes kieselguhr covering material;
(3) putting in appropriate deionized water together by polyvinyl alcohol, dioctyl sodium sulfosuccinate, Carboxymethyl cellulose sodium, Oleum Fructus Bruceae, stirring is completely dissolved dispersion to material, makes slow release coating agent standby;
(4) other leftover materials are mixed homogeneously with step (1), (2) gained material; put into pelletize in comminutor; and spraying slow release coating agent prepared by step (3) at prepared particle surface, the granule after peplos, through hot air drying, room temperature cooling, gets product.
The beneficial effects of the present invention is: raw material wide material sources in formula, take full advantage of material common during daily life produces, while reducing production cost, improve the single fixing phenomenon of conventional composite fertilizer nutrient;The heat produced during utilizing medical stone powder and poly-silicic acid iron sulfate in production technology and gas can promote kieselguhr and the good nutrition absorption in raw material, reach stable covered effect;The slow release coating agent obtained with the mixed raw material such as polyvinyl alcohol, Carboxymethyl cellulose sodium, has stable slow-release capability, and the Oleum Fructus Bruceae taste being wherein coated with is the most bitter, can protect fertiliser granulates to a certain extent;Compound fertilizer prepared by the present invention utilizes kieselguhr and slow release coating agent that nutrient is formed dual cladding, nutrient not easily runs off, fertilizer efficiency is the most lasting, crop each growth period desired nutritional can be met, and do not destroy ecological environment of soil, it is the compound fertilizer of a kind of novel green high-efficient, can significantly improve crop yield and quality in actual applications, increase economic efficiency.
Detailed description of the invention
