본 발명의 실시에서 참나무 목초액을 증류하고 정제하여 타르 성분을 완전히 제거한 목정수와 반응시키는 산화칼슘은 이미 패화석으로 생산된 제품(농림부 고시 제96-96호, 비료공정규격)을 사용하여도 되나, 저렴한 비용으로 대량 생산하기 위하여 양계 또는 굴양식 부산물인 계란 껍질이나 굴껍질을 사용하였다.In the practice of the present invention, distilled and purified oak vinegar solution and calcium oxide reacted with wood purified water completely removed from the tar component may be used already manufactured products of calcite (Ministry of Agriculture, Notice No. 96-96, fertilizer process standard). Egg shells or oyster shells, which are by-products of poultry or oyster farming, are used for mass production at low cost.
이 때, 산화칼슘을 얻기 위한 연소 전과 연소 후의 계란 껍질과 굴 껍질에 함유된 칼슘량은 표 2 및 3과 같다.At this time, the amounts of calcium contained in egg shells and oyster shells before and after combustion to obtain calcium oxide are shown in Tables 2 and 3.
상기 표에서 알 수 있듯이, 식물에 직접 이용될 수 있는 수용성 형태의 칼슘이 연소전 보다 연소 후에 약 140배 이상 증가한 반면 가용성 형태나 전량의 칼슘은 1.2∼1.6 배 정도 증가하는데 그쳤다.As can be seen from the table, the water-soluble form of calcium that can be directly used in plants increased about 140 times after combustion than before combustion, while the soluble form or total amount of calcium increased only by 1.2-1.6 times.
목정수와 계란칼슘 또는 굴칼슘의 반응물은 50℃의 열풍건조기로 건조시키지 않고 실온에서 건조시켜도 되는데, 10시간 이상이 소요되기는 하나 비료 성분량에는 차이가 없었다.The reactants of wood crystal water and egg calcium or oyster calcium may be dried at room temperature without drying with a hot air dryer at 50 ° C., although it takes more than 10 hours, there is no difference in the amount of fertilizer.
또한, 이렇게 건조된 입자는 특별한 분쇄기를 사용하지 않아도 쉽게 분쇄되는데, 이와 같은 방법으로 계란칼슘이나 굴칼슘 1,000g을 목정수 1,000㎖를 반응시키면 약 1,300∼1,400g의 목정분말을 얻을 수 있었다.In addition, the dried particles are easily pulverized even without using a special grinder. In this way, when 1,000 g of egg calcium or oyster calcium are reacted with 1,000 ml of wood water, wood powder of about 1,300 to 1,400 g was obtained.
상기와 같이 제조된 목정분말에 함유된 형태별 칼슘 함량은 표 4 및 5에서 보는 바와 같다.The calcium content of each type contained in the wood powder prepared as described above is as shown in Tables 4 and 5.
즉, 계란칼슘과 굴칼슘을 목정수와 반응시키면 반응전보다 가용성 형태나 전량의 칼슘은 1∼2% 정도 증가하는 반면 수용성 형태의 칼슘은 6∼7% 정도나 증가하였다.In other words, when the egg calcium and oyster calcium were reacted with Moksu water, the soluble form and the total amount of calcium increased by 1 to 2%, while the water soluble form increased by 6 to 7%.
한편, 계란칼슘 및 굴칼슘과 목정수 반응물의 물에 대한 pH는 표 6에서 보는 바와 같이 거의 비슷한 값을 나타내어 pH 차이가 거의 없었다.On the other hand, the pH of the water of the egg calcium, oyster calcium and wood jeongsu water reactant showed almost similar values as shown in Table 6, there was almost no pH difference.
상기와 같이 제조된 목정분말은 다량의 칼슘이 함유되어 있는데, 이 칼슘을 추출하여 액상칼슘비료를 만들었다.The wood grain powder prepared as described above contains a large amount of calcium, which was extracted to form a liquid calcium fertilizer.
즉, 계란껍질을 이용한 목정분말 또는 굴목정분말을 이용하여 수용성 칼슘이 17% 이상인 액상칼슘비료(농림부 고시 제96-96호, 비료공정규격)를 만들었다.That is, liquid calcium fertilizer (notified by the Ministry of Agriculture and Forestry No. 96-96, fertilizer process standard) having 17% or more water-soluble calcium was made using wood powder or oyster wood powder using egg shell.
상기 실시예에 의하면 굴과 계란목정분말 1,000g을 사용하여 각각 약 2,000㎖와 2,600㎖의 액상칼슘을 얻을 수 있었다.According to the above embodiment, about 2,000 ml and 2,600 ml of liquid calcium were obtained using 1,000 g of oyster and egg wood powder, respectively.
굴목정분말의 경우 2차 반응이 완료된 후에 겔과 같은 상태로 되므로 계란목정분말의 경우보다 얻어지는 양이 적었다.In the case of the lumberjack powder, it was in a gel-like state after the completion of the secondary reaction.
이 여액에 함유된 수용성 칼슘(CaO)량은 굴목정분말의 경우 18.3%, 계란목정분말의 경우 18.7% 수준이었다.The amount of water-soluble calcium (CaO) contained in this filtrate was 18.3% for the wood grain powder and 18.7% for the eggwood powder.
한편, 농가에서 수경재배시 영양액을 조제하는데 이용하는 칼슘원을 목정분말에서 추출한 액상칼슘으로 대체할 수 있는지 조사하기 위해 기본 양액에 액상칼슘비료, Ca(NO3)2·4H2O, CaCl2·6H2O을 각각 칼슘이온(Ca2+) 농도가 200ppm 수준이 되도록 첨가하여 양액을 만들었다.On the other hand, in order to investigate whether the calcium source used to prepare nutrient solution for hydroponic cultivation in farmhouses can be replaced with liquid calcium extracted from wood powder, the liquid nutrient fertilizer, Ca (NO 3 ) 2 · 4H 2 O, CaCl 2 · 6H 2 O was added to the calcium ion (Ca 2+ ) concentration of 200ppm, respectively, to prepare a nutrient solution.
이때, 액상칼슘이 첨가되는 양은 굴목정분말에서 추출된 액상칼슘의 경우 30.58㎖/10ℓ, 계란목정분말에서 추출된 액상칼슘의 경우 31.94㎖/10ℓ이었다. 시금치, 배추, 열무, 보리 및 오이 등을 30일 동안 담수 수경재배한 결과, 사용한 칼슘원에 따라 작물의 생육상태에서 통계적인 차이가 없었다. 따라서 기존에 사용되고 있는 칼슘비료원을 새로 제조한 액상칼슘비료로 대체해서 사용해도 작물재배에는 무방하며 관주용이나 엽면시비용으로 사용하여도 효과적이다. 단지 액상칼슘비료는 강산성(pH 1.3)이기 때문에 양액의 pH 조절이 필요하다.At this time, the amount of added liquid calcium was 30.58ml / 10l for the liquid calcium extracted from oyster wood powder, 31.94ml / 10l for the liquid calcium extracted from egg wood powder. Freshwater hydroponic cultivation of spinach, Chinese cabbage, radish, barley and cucumber for 30 days showed no statistical difference in the growth of crops depending on the calcium source used. Therefore, it can be used for crop cultivation by replacing the existing calcium fertilizer source with newly prepared liquid calcium fertilizer, and it is also effective for irrigation or foliar cost. Only liquid calcium fertilizer is strongly acidic (pH 1.3), so it is necessary to adjust the pH of the nutrient solution.
상기 반응물의 분석은 전북대학교 농과대학 토양비료학 실험실과 기기 분석실에서 실시하였으며 그 방법은 다음과 같다.The reactants were analyzed in the soil fertilizer laboratory and instrument analysis room of the College of Agriculture Chonbuk National University, the method is as follows.
수용성 칼슘량은 시료 1∼2g을 물 100㎖에 넣고 환류 가열시킨 다음 냉각시키고 여과(No. 2. Toyo)하였다. 가용성 칼슘량은 시료 1∼2g을 0.5N HCl 200㎖와 혼합하고 30분 정도 가열하고 냉각시킨 다음 여과하였다. 총 칼슘량은 시료 2∼5g을 진한 HCl 30㎖와 진한 HCO310㎖와 혼합한 다음 30분간 가열하고 냉각시킨 다음 여과하였다. 이 여액을 유도결합프라즈마 분광기(Inductively Coupled Plasma Spectro- meter, Shimadzu, ICPS-7500, 일본)를 사용하여 정량 하였다.The water-soluble calcium amount was added to 1-2 g of the sample in 100 ml of water, heated to reflux, cooled, and filtered (No. 2. Toyo). The amount of soluble calcium was mixed with 200 ml of 0.5 N HCl, heated for about 30 minutes, cooled, and filtered. The total amount of calcium was mixed with 30 ml of concentrated HCl and 10 ml of concentrated HCO 3 after heating 2-5 g of the sample, followed by heating for 30 minutes, cooling, and filtration. This filtrate was quantified using an Inductively Coupled Plasma Spectrometer (Shimadzu, ICPS-7500, Japan).
또한, 액상칼슘제제에 함유된 칼슘량은 증류수로 적당히 희석한 다음 유도결합플라즈마 분광기로 측정하였으며, 반응물의 pH는 시료 5g을 증류수 50㎖와 혼합하고 1시간 동안 교반한 후 pH meter(Jenco, 1671, USA)를 사용하여 측정하였다.In addition, the amount of calcium contained in the liquid calcium preparation was properly diluted with distilled water and measured by an inductively coupled plasma spectrometer. , USA).
본 발명은 특별한 장치 없이도 간단·용이하게 양계 또는 굴양식 부산물인 계란껍질이나 굴껍질 및 기타 조개껍질 등을 사용하여 저렴한 비용으로 액상칼슘비료를 대량 생산할 수 있다.The present invention can easily and easily produce a large amount of liquid calcium fertilizer at low cost by using egg shells or oyster shells and other shells, such as poultry or oyster farming by-products, without a special device.
상기 액상칼슘비료는 산화된 계란칼슘 또는 굴칼슘보다 식물에 직접 이용될 수 있는 수용성 칼슘을 다량 함유하여 유효 칼슘의 흡수 효과가 매우 우수하며, 수경재배용, 관주용이나 엽면시비용으로 사용될 수 있다.The liquid calcium fertilizer contains a large amount of water-soluble calcium which can be directly used in plants than oxidized egg calcium or oyster calcium, and has an excellent effect of absorbing effective calcium, and can be used for hydroponic cultivation, irrigation or foliar cost.
또한, 본 발명은 인체에 해가 없고 토양 개량 및 병해 방지 효과가 있어 농약을 사용하지 않는 유기농법 또는 환경보존형 농법에 효율적으로 활용될 수 있다.In addition, the present invention is harmless to the human body and has an effect of improving the soil and preventing diseases can be effectively utilized in organic farming or environmental conservation farming methods do not use pesticides.
