It contributes to the improvement of high quality and the increase of farm income, and it is coated with chitosan lactate aqueous solution, which is antibacterial against plant pathogen It relates to sex, coated slow release fertilizers and a method of manufacturing the same using the oyster shell showing various physiological activities such as a plant activator action and calcium absorption promoting effect.
    [3] Oyster shells are made from oyster shells inhabiting the sea, and are produced in large quantities in coastal areas such as fishing villages.
    [4] Therefore, some methods for utilizing the oyster shell shells that are left at seaside are in progress, and some companies in Korea are operating production of fossil fertilizers using oyster shell shells. However, at present, the technical process in the fertilizer business of recycling oyster shell fossils at home and abroad is manufactured through the process of simply collecting, washing, firing (300 ~ 500 ℃), grinding, sorting, and packing. Fertilized fertilizer produced through this process is limited to fertilizer method because it is used only as a substitute for lime and soil, and because of falling in price competitiveness with lime powder, there is a problem with the market, so it is not only difficult for the producers to manage. The recycling of waste resources still remains a problem.
    [5] Accordingly, an object of the present invention is to solve the problem that the conventional oyster shell shell was used in a limited way, after calcining the oyster shell shell at a high temperature to chelate the calcium of the oyster shell itself to obtain the oyster shell shell powder, a certain amount of amino acids Add neutralizing solution, fertilizer, trace elements, microorganisms and plant extracts of nitrogen (N-NO 3 , N-NH 3 ), phosphorus (P 2 O 5 ) and potassium (K 2 O), and assemble into balls By applying heat to functional materials such as chitosan and spraying them with fog, it is not only effective as a soil improver but also as a fertilizer for rice crops, forests, and fruit trees, and its antibacterial activity against plant pathogens by coating with chitosan lactate. To provide a slow-acting coating fertilizer using the oyster shell of the new method showing a variety of physiological activity, such as, plant activator action and its manufacturing method.
    [1] Figure 1 shows the manufacturing process of the slow-effective coating fertilizer using the oyster shell according to the present invention.
    [6] In the present invention, calcium chelated oyster shell powder 40 to 80% by weight, amino acid neutralization 1 to 15% by weight, nitrogen (N-NO 3 , N-NH 3 ) 5 to 20% by weight, phosphorus (P 2 O 5 ) 5-20 wt%, potassium (K 2 O) 5-20 wt%, B 2 O 3 0.01-1 wt%, MnO 0.1-5 wt%, iron (Fe) 0.1-5 wt%, chitosan 0.001-0.1 It is characterized by a slow-acting coating fertilizer using oyster shell containing the weight percentage, 0.001 to 0.1% by weight of microbial components and 0.5 to 1% by weight of the plant extract.
    [7] In addition, the present invention calcined oyster shell shell in a high temperature tower refractory drying furnace of 800 ~ 1200 ℃ for 3 to 4 hours to transform the calcium of the oyster shell itself by chelating, and then through the cooling process to prepare a powder of oyster shell, Neutralization liquid containing amino acid component and fertilizer, trace elements, microbial component and plant extract of nitrogen (N-NO 3 , N-NH 3 ), phosphorus (P 2 O 5 ) and potassium (K 2 O) And then mixed, and then assembled into a ball shape, including a method of producing a slow-effective coating fertilizer using a oyster shell coating treatment with a functional material.
    [8] The present invention will be described in more detail as follows.
    [9] The present invention uses a oyster shell shell Calcium chelate by firing at high temperature, a certain amount of amino acids and nitrogen (N-NO 3 , N-NH 3 ), phosphorus (P 2 O 5 ) and potassium (K 2 O) Fertilizer raw materials, trace elements (B 2 O 3 , MnO, Fe, etc.), microorganisms and plant extracts (a small amount of Mg, I, Fe, Ca, fiber, etc.) are added and then coated with functional materials such as chitosan The present invention relates to a slow-coat coating fertilizer to be treated and a method for producing the same.
    [10] Here, the chemical composition composition ratio (%) of the raw oyster shell as the raw material of the oyster shell is shown in Table 1 below, the specific gravity of the raw oyster shell is 1.0, the pH is 8.5. In addition, when the raw oyster shell shell is calcined for 3 to 4 hours in a high temperature tower refractory drying furnace of 800 ~ 1200 ℃, chelated oyster shell is obtained. At this time, the chemical composition of the chelated oyster shell (%) is shown in Table 2, the specific gravity is 0.5 and the pH is 12.5.
    [11]
    [12]
    [13] In particular, in the present invention, by using the chelated oyster shell having the above composition, since the chelated CaO absorbs water and becomes Ca (OH) 2 water-soluble, the effect of promoting absorption of calcium to plants is enhanced. .
    [14] When described according to the method for producing a slow-effective coating fertilizer using the oyster shell according to the present invention.
    [15] First of all, the first process carries out the raw material input and storage process. To this end, oyster shell raw materials obtained from oyster farms are calcined for 3 to 4 hours in a high temperature tower refractory dryer at 800 to 1,200 ° C. to obtain chelated calcium raw materials, which are then stored in a storage tank. At this time, it is divided into raw materials received by trucks and raw materials received by bulk bags. In the present invention, the oyster shell shell is used at 40 to 80% by weight, and unlike lime powder, there is no soil obstacle even when used excessively.
    [16] The next step is to perform the raw material grinding process, which is 5 to 20% by weight of oyster shell raw material chelated calcium stored in the storage tank and nitrogen (N-NO 3 , N-NH 3 ) added in the next process, phosphorus (P 2 O 5 ) 5 to 20 wt%, potassium (K 2 O) 5 to 20 wt%, B 2 O 3 0.01 to 1 wt%, MnO 0.1 to 5 wt%, iron (Fe) 0.1 to 5 wt%, microorganisms In order to uniformly mix 0.001 to 0.1% by weight of the component and 0.5 to 1% by weight of the plant extract to make a single particle, it is pulverized into a bao-mill and fed to the raw material auxiliary tank. The microorganism component used in the present invention is a photosynthetic bacterium (Rhod Bact.), Which is used to supply insoluble phosphoric acid that cannot be absorbed by the root of the plant, and is used at 0.001 to 0.1% by weight. desirable.
    [17] Then, the mixing process is carried out through the weighing process of each added component, and the seed (SEED) which recycles the neutralized liquid (amino acid), powder fertilizer raw material, trace element and microbial ingredient raw material which is quantitatively supplied according to the composition of each product. Mix evenly with and paddle mixer to produce a moist product of about 10% moisture.
    [18] The next process is to perform the granulation process of rotating particles in the drum-type granulator to make the particles, which is about 10% of the moisture, and this process is also based on the mixing process and the size and granulation state of the process. It is an important process that directly affects the product.
    [19] It is a drying process to be performed after the above process, in which the assembled wet product of about 10% moisture is heat-exchanged with hot air (400-500 ° C.) heated by direct heating bunker-C oil in a co-current rotary dryer. The water is evaporated so that the water in the water becomes 1 to 2%.
    [20] Then, the oyster shell powder prepared through the drying process is put into a drum type granulator and rotated to perform mist spraying of chitosan, which is a functional material, by applying heat of 120 ° C.
    [21] In the case of a product heated at a temperature of 90 to 100 ° C. during the drying process, the primary cooled product is first cooled to 70 to 80 ° C. using air at room temperature in a parallel rotary cooler. Using a vibrating sieve, three stages are separated according to the particle size into the following lumps, products, and undetermined to perform the sorting process according to the purpose. The tuber shows a size of 6 mesh or more (large particles over 6 mesh bodies, 3.35 mm or more), and the product is 6-12 mesh sizes (6 mesh bodies pass through and 12 mesh bodies, and 3.35 to 1.7 mm size). Particles), and undetermined indicates a size of 12 mesh or more (small particles passing through the 12 mesh body, which is 1.7 mm or less).
    [22] In the sorting process performed after the above process, the separated large particles (lumps) (6 mesh or more) are broken into pieces smaller than the product particles (6-12 mesh size) using a hammer grinder, and the milled product is undecided. Resupply to the mixing process with (> 12 mesh size). Then, the product particles separated in the sorting process are discharged by a certain amount as a production base using a fixed-quantity feeder and an impact-line flow meter, and the rest are re-supplied to the mixing process to form particles.
    [23] The next process is to finally cool the product by using air at room temperature so that a certain amount of discharged product can be packaged in a rotary cooler.
    [24] When the secondary cooling is completed in the above, the product is transferred to the elevator and stored in the product cycle, and if necessary, the product is weighed with a packing machine based on a 20 kg unit, and put into a polyethylene (PE) or polypropylene (PP) bag. It is loaded, glued or machined, and loaded onto pallets.
    [25] In addition, after performing a dust collecting step of removing pollutants (dust, ammonia, etc.) in the exhaust gas generated by the dryer below the pollution standard value using a dust collector, the dust in the exhaust gas is collected by centrifugal force, and the collected dust is collected. The present invention is completed by supplying the car cooler.
    [26] Hereinafter, the present invention will be described in detail based on the following examples, but the present invention is not limited thereto.
    [27] Example
    [28] The oyster shell raw material obtained from the farm was calcined for 3 to 4 hours in a high temperature tower refractory dryer at 800 to 1,200 ° C. to obtain a chelated calcium raw material, and then the raw materials (excluding chitosan) were weighed and mixed as shown in the following Table 1 to obtain 10% moisture. The wet product, which is internally and externally, was directly heat-exchanged in a drum-time granulator and heat-exchanged with heated hot air (400-500 ° C) to evaporate the moisture so that the moisture in the product would be 1-2%.
    [29] Then, the obtained solids were introduced into a drum type granulator and rotated, while chitosan as a functional substance was heated at 120 ° C., and mist was sprayed to rotate the granulator over 10 minutes until the contents were formed by chitosan.
    [30] After the coating was finished, when the heat of the product was completely cooled during the drying process, the screening process was carried out to separate the three stages into a lump, product, undecided, etc. to perform the screening process according to the purpose. Here, the lump is a size of 6 meshes or more (large particles over 6 mesh bodies, 3.35 mm or more), and the product is 6-12 mesh sizes (6 mesh bodies pass through and 12 mesh bodies, 3.35 to 1.7 mm). Microparticles | fine-particles), and undetermined | determine represents the size of 12 meshes or more (small particle which passes through 12 mesh bodies, and it is 1.7 mm or less).
    [31] The product produced in this way should have an initial dissolution rate of nitrogen (30 ℃, political dissolution in water within 24 hours) of 50% or less.
    [32]
    [33] Experimental Example
    [34] The effectiveness of the soil-improving agent and fertilizer of the above-described slow-acting cover fertilizer and oyster shell powder fertilizer was compared. In other words, fertilized powdered fertilizer 4ton / ha and slow-covered fertilizer 1ton / ha were fertilized in sandy acidic soils with pH 5.5. The pH of the crushed fossil powder, which is a test material, was 8.5, and the pH of the efficacious coating fertilizer was 12.5. The efficacious coating fertilizer had a higher alkalinity than that of the crushed fossil powder. Increasing the amount of water was increased, and the pests and robes that were problematic due to excessive fertilization were alleviated and safe production was possible.
    [35] In addition, in the case of a slow-covering fertilizer, the leaves and stems of the plant grow rapidly by the chelated CaO, so that the sunlight is evenly distributed to the lower leaves to facilitate the photosynthesis action, and the phyto-activator action is caused by the added photosynthetic bacteria. It is excellent, as well as the functional material chitosan is coated to act as an antibacterial against pests. In addition, since the chelated CaO absorbs water and becomes Ca (OH) 2 soluble, the absorption promoting action of calcium is enhanced.
    [36] Therefore, as a result of fertilizing the fertilizer coating fertilizer and crushed fossil powder fertilizer on paddy soil, rice yield was increased by 11% for the efficacious fertilizer coating fertilizer than the crushed powder fertilizer.
    [37] In addition, as a result of fertilizing the fertilized pear orchard and the sintered powder fertilizer, the sorghum coated fertilizer was harvested about one week earlier than the foliated powder fertilizer, and the quality of the product was much better.
    [38] As described above, the slow-acting coating fertilizer using the oyster shell of the present invention is a slow-acting coating fertilizer prepared as a new technology of the new method, unlike the existing products that are simply used as a substitute for lime and soil improver, but also has an effect as a soil improving agent Particles can be sorted according to the requirements, such as crops, forests, orchards, which can be used as fertilizers to meet fertilization standards. In addition, the coating fertilizer by the technique of the new method is a coating fertilizer that exhibits various physiological activities such as antibacterial activity, plant activator action and calcium absorption promotion action against plant pathogens because it is specially manufactured with chitosan lactate aqueous solution. It is expected that the lasting effects such as moisturizing and flexible filamentation will be very high.
