본 발명은 굴패각을 이용한 완효성 피복비료 및 그 제조방법에 관한 것으로서, 더욱 상세하게는 고온에서 소성처리하여 굴껍질 자체의 칼슘을 킬레이트화시킨 굴패각 껍질 분말에 일정량의 아미노산 중화액과 질소(N-NO3, N-NH3), 인(P2O5) 및 칼륨(K2O) 중에서 선택된 분체 비료원료, 미량요소 및 미생물 성분을 함유시키고 볼 모양으로 조립한 후 키토산 등의 기능성물질로 코팅 처리함으로써, 종래 굴패각을 이용한 경우 단순히 석회대용물질과 토양개량제로만 사용되었던 것과는 달리, 토양 개량제로서의 효과 뿐만 아니라 각 작물에 맞게 입자를 선별하여 어떠한 작물(수도작, 산림, 과수 등)이든 시비 기준에 맞게 비료로도 사용할 수 있어 농산물의 고품질 향상과 농가 소득 증대에 기여하고, 키토산 유산염 수용액으로 코팅되어 식물 병원균에 대한 향균활성, 식물 활성제작용 및 칼슘 흡수 촉진작용 등의 다양한 생리활성을 나타내는 굴패각을 이용한 완효성 피복비료 및 그 제조방법에 관한 것이다.The present invention relates to a slow-acting coating fertilizer using oyster shells and a method of manufacturing the same, and more particularly, a certain amount of amino acid neutralization liquid and nitrogen (N-NO3) in oyster shell shell powder chelated calcium of the oyster shell by firing at high temperature In the case of using conventional oyster shell by containing powder fertilizer material selected from N-NH3), phosphorus (P2O5) and potassium (K2O), microelements and microorganisms, assembling them into balls and coating them with functional materials such as chitosan. Unlike simply used as a lime substitute and soil improver, it can be used as fertilizer to meet the fertilization standards of any crops (manure crops, forests, fruit trees, etc.) by selecting particles for each crop as well as its effect as a soil improver. 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.

굴패각 껍질은 바다에서 서식하는 굴 껍질을 원료로 하는 것으로, 어촌 등 해안가에서 다량으로 생산되며, 주로 폐기물로서 인식되어 그대로 방치되고 있다.Oyster shells are made from oyster shells inhabiting the sea, and are produced in large quantities in coastal areas such as fishing villages.

따라서, 이렇게 해안가에서 방치되고 있는 굴패각 껍질을 활용하기 위한 방법이 일부 진행되고 있으며, 국내의 일부 업체에서는 굴패각 껍질을 이용하여 패화석 비료를 생산가동 중에 있다. 그러나, 현재 국내외적으로 굴껍질 패화석을 재활용하는 비료화 사업에서의 기술공정은 단순히 수거단계, 세척단계, 소성단계(300∼500 ℃), 분쇄단계, 선별단계, 그리고 포장단계의 공정을 거쳐서 제조되어 이러한 공정을 거쳐 생산된 패화석 비료는 단지 석회 대용물질과 토양개량제로만 활용되기 때문에 시비방법이 한정되어 있고, 석회분말과의 가격경쟁력에서 뒤지기 때문에 판로에 문제가 있어 생산업체에서는 경영의 어려움은 물론이고 폐기물 자원의 재활용에도 여전히 문제점으로 남아 있다.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.

따라서, 본 발명의 목적은 종래 굴패각 껍질이 제한적으로 사용되었던 문제점을 해결하기 위한 방안으로, 굴패각 껍질을 고온에서 소성처리하여 굴껍질 자체의 칼슘을 킬레이트화시켜 굴패각 껍질 분말을 얻은 후에, 일정량의 아미노산 중화액과 질소(N-NO3, N-NH3), 인(P2O5) 및 칼륨(K2O)의 비료원료, 미량요소, 미생물 성분 및 식물추출액을 첨가시키고, 볼 모양으로 조립하여 키토산 등의 기능성물질로 열을 가하면서 안개 분사시켜 코팅 처리함으로써, 토양 개량제로서의 효과 뿐만 아니라 수도작, 산림, 과수 등의 비료로서의 효과도 우수하며, 키토산 유산염 등의 코팅으로 식물 병원균에 대한 향균활성, 식물 활성제작용 등 다양한 생리활성을 나타내는 새로운 공법의 굴패각을 이용한 완효성 피복비료와 그 제조방법을 제공하고자 한다.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.

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.

특히, 본 발명에서는 상기 조성을 갖는 킬레이트화된 굴패각을 이용함으로써, 킬레이트화된 CaO가 물을 흡수하여 Ca(OH)2의 수용성이 되기 때문에 식물의 칼슘에 대한 흡수촉진작용이 증강되는 효과를 나타내게 된다.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. .

이러한 본 발명에 따른 굴패각을 이용한 완효성 피복비료를 그 제조방법에 의거하여 설명하면 다음과 같다.When described according to the method for producing a slow-effective coating fertilizer using the oyster shell according to the present invention.

먼저, 첫 번째 과정은 원료투입 및 저장과정을 수행한다. 이를 위해 굴양식장에서 얻은 굴패각 원료를 800∼1,200 ℃의 고온탑 내화 건조기에서 3∼4 시간 동안 소성시켜 킬레이트화된 칼슘 원료를 얻은 다음, 이를 저장탱크 내에 투입하여 저장한다. 이때, 트럭으로 입고되는 원료와 벌크백으로 입고되는 원료로 구분된다. 본 발명에서는 굴패각 껍질을 40 ∼ 80 중량%로 사용하며, 이때 석회분말과는 달리 과잉 사용하여도 토양장애가 없는 것이 특징이다.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.

상기 과정 다음으로 수행하는 선별공정에서는 상기에서 분리된 큰입자(괴정)(6메쉬 이상)를 햄머 분쇄기를 이용하여 제품입자(6 ∼ 12메쉬 크기)보다 작게 부수는 공정으로서, 분쇄된 제품은 미정(12메쉬 이상 크기)과 함께 혼합공정으로 재공급한다. 그리고, 선별공정에서 분리된 제품 입자를 정량공급기 및 충격선(Impact-line) 유량계(Flow meter)를 이용하여 공정 생산 베이스 만큼 일정량 배출시키고 나머지는 입자 형성을 위하여 혼합공정으로 재공급한다.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.

실험예Experimental Example

상기와 같이 제조된 완효성 피복비료와 굴패각 분말비료와의 토양개량제와 비료로서의 효능에 대해서 비교해 보았다. 즉, pH 5.5인 사질 산성토양에 패화석 분말비료 4ton/ha, 완효성 피복비료 1ton/ha를 시비하여 일반계 품종인 동진벼의 어린묘를 6월 5일 기계 이양하여 난괴법으로 3회 반복하여 수행한 결과, 공시 재료인 패화석 분말의 pH는 8.5, 완효성 피복비료는 pH가 12.5로서 패화석 분말 보다 완효성 피복비료가 알칼리성이 높기 때문에 질소의 과잉 흡수를 억제하고 인산의 비효를 높여 주는 효과가 나타났으며, 질소량을 늘려 증수가 되고 과다 시비로 문제가 되는 병충해나 도복이 경감되어 안전 생산이 가능하였다.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.

또한, 완효성 피복비료인 경우, 킬레이트화된 CaO에 의해서 식물의 잎과 줄기가 빳빳하게 자라므로 햇빛을 아래쪽의 잎까지 골고루 받게 하여 광합성 작용을 원활하게 하고, 첨가된 광합성 세균에 의하여 식물활성제 작용이 뛰어 나며, 뿐만 아니라 기능성 물질인 키토산이 코팅되어 병충해에 대한 항균작용을 한다. 그리고, 킬레이트화된 CaO가 물을 흡수하여 Ca(OH)2의 수용성이 되기 때문에 식물의 칼슘에 대한 흡수촉진작용이 증강된다.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.

따라서, 완효성 피복비료와 패화석 분말비료를 논토양에 시비한 결과, 벼 수확량은 패화석 분말비료 보다 완효성 피복비료인 경우 11%의 증수효과를 나타내었다.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.

또한, 유목인 배 과수원에 완효성 피복비료와 패화석 분말비료를 시비한 결과, 완효성 피복비료가 패화석 분말비료에 비해 수확시기가 1주일 가량 빨랐으며, 상품의 질도 훨씬 뛰어났다.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.

이상에서 설명한 바와 같이, 본 발명의 굴패각을 이용한 완효성 피복비료는 새로운 공법의 신기술로서 제조한 완효성 피복비료로서 단순히 석회대용물질과 토양개량제로만 사용되는 기존제품과는 달리, 토양 개량제로서의 효과도 있지만 작물에 맞게 입자를 선별하여 어떤 작물(수도작, 산림, 과수 등)이든 시비 기준에 맞게 비료로도 사용 할 수 있으므로 농산물의 고품질 향상과 농가 소득 증대에 기여할 것으로 기대된다. 또한, 신공법의 기술에 의한 피복비료는 키토산 유산염 수용액으로 특수 제조되었기 때문에 식물 병원균에 대한 향균활성과 식물 활성제작용 및 칼슘 흡수 촉진작용 등의 다양한 생리활성을 나타내는 피복비료이며 강한 흡착성에 의한 피복막 형성으로 생기는 보습성이나 유연 사상성 등의 지속효과가 매우 높을 것으로 기대된다.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.
