      • 全南地方에 分布하는 新干拓地 土壤의 理化學的 特性에 關한 調査 硏究

        孫寶均 순천대학 새마을연구소 1986 새마을硏究論文集 Vol.2 No.-

        An investigation was carried out to determine the morphological and physico-chemical characteristics of the newly reclaimed marine soil distributed in Chonnam area and the number of experimented soil samples was 1,303. Results showed that the majority of soil series in these regions surveyed were Poseung Kwanghwal and Podu, whereas Yulpo, Pori and Jeonbug series were slightly distributed. Much groundshells was mostly found in uncultivated polderland. In the chemical properties by cultivation system, the average contents of Ex.-K.Ex.-Ca, Ex.-Mg, Av.-SiO_2, soil pH and CEC in the polderland were in order of uncultivated polderland>cultivated polderland>mature polderland, while on the other, the average contents of soil organic matter, Ac.-P_2O_5 and Av.-Zn were in reverse order. In comparison of the chemical properties with different regions, the average contents of soil organic matter, Av.-P_2O_5 and EX.-Ca in the southern coastal region were higher than those of the northwestern coastal region, and, in the concentration of Sodium chloride and soil pH value, vice versa

      • 니켈 촉매에 의한 동백유의 수소화에 관한 연구

        안호근,손보균,임한진 순천대학교 공업기술연구소 1998 工業技術硏究所論文集 Vol.12 No.-

        The reaction conditions were investigated to prepare the hardened oil with suitable properties from Camellia japonica oil by catalytic hydrogenation in batch reactor at atmosphere. The nickel-based catalysts were used, and the hydrogenation activity of the catalyst was measured as iodine value. The commercial Pricat-9920 catalyst was highly active. The hydrogenation rate over Pricat-9920 catalyst was increased with increasing reaction temperature to 180℃, but decreased over 180℃ because the dissolution of hydrogen in the oil was difficult at high temperature. Also, the rate depended on the amounts of catalyst used, the flow rate of hydrogen, and agitation rate, which were deeply related to the diffusion of hydrogen in the pore of the catalyst. The hardened oil with melting point 30~40℃ was obtained at reaction time 4~6hr, reaction temperature 180℃, the amounts of catalysts 0.2%Ni(w/v), and the flow rate of hydrogen 50cc min^(-1). The relationship between iodine value and melting point was linear, so the iodine value could be easily estimated from the melting point.

      • 南部 畓地帶에서 發生하는 올챙이고랭이(Scirpus juncoides Roxb.)의 雜草生態的 硏究

        許祥萬,金晋鎬,孫寶均 順天大學校 1984 論文集 Vol.3 No.1

        This study on the occurrence, regeneration and reproduction of the problematic weed, Scirpus juncoides Roxb., in the paddy field in the southern area was carried on for 12 months in order to investigate the various adaptability. The results obtained are as follows: 1. In O₂condition, a slightly insufficient condition treated by 0.02mm polyethylene film was the most favorable for germination. 2. In temperature, the more favorable condition for the germination of S.juncoides Roxb. seed was 35℃, 30℃, 25℃ in order, and the emergence rate of their stumps was high from 20℃ to 30℃. 3. In light intensity, germinating rate of S.juncoides Roxb. seed was higher in shade conditions than in perfect exposure, and so was the emergence rate of stump. 4. In light quality, germinating rate of S.juncoides Roxb. seed was high in order of black, yellow, green, and colorless film, while the emergence rate of stump was high in green film treatment. 5. In hydrogen-ion concentration of soil, the most optimun pH value for germination was 5.7, while in the extemely acid and alkaline soil, the growth was checked after the sixth week. 6. The emergence rate of stump was high in order of 3g, 4g, 5g, 2g, 1g in stump weight. 7. Initial growth of S.juncoides Roxb. shoot at two weeks after its cutting depended on underground nutrition. 8. Regeneration vigour of S.juncoides Roxb. shoot became dull since a growth period, and only one cutting after 25, May was enough to control S.juncoides Roxb. 9. Cutting of S.juncoides Roxd. shoot in the lagvegetative period around the end of May did not affected its regrowth. 10. In soil moisture content, the number of flower-bud was more in 100% saturated condition than in 80% saturated. In the submergence condition, 2cm water flooded depth was the most favorable for flower-bud formation of S.juncoides Roxb. 11. There was no constant tendency in soil condition and poor aeration condition was well adapted to S.juncoides Roxb. 12. As the shade rate increased, the flower-bud formation of S.juncoides Roxb. was suppressed. 13. The flower-bud formation of S.juncoides Roxb. was increased in yellow polyethylene film treatment. 14. with the MPK fertilizer level increased, the number of flower-bud was rapidly increased.

        산국의 수량과 유효성분에 대한 NPK의 효과

        이경동,양민석,정연규,손보균,조주식,이성태,김필주 한국농화학회 2003 Applied Biological Chemistry (Appl Biol Chem) Vol.46 No.2

        본 연구는 3요소(N-PO_2O_5-K_2O)처리가 산국(Chysanthemum boreale M.)의 수량과 유효성분에 미치는 효과를 조사하여 효과적인 재배시스템을 개발하고자하였다. 처리구는 무처리, NPK(250-160-160), NK(250-0-160), PK(0-160-160kg/ha)의 5처리로 설정하여 산국을 재배한 결과, 건물수량은 NPK처리구가 PK처리구에 비하여 4.0배의 증수가 있었으며, 다른 처리구보다 무기이온의 흡수율, 생육 및 수량에서 NPK처리구가 가장 우수하였다. 식용으로 많이 쓰이는 꽃의 주요 아미노산은 proline, glutamic acid과 aspartic acid이였고, 다른 처리구들에 비하여 NPK처리구가 높은 함량을 보였다. 혈압강하효과가 우수한 cumambrin A는 PK처리구에 비하여 NPK처리구가 6.2배의 증수효과가 있었다. NK처리구는 NP처리구보다 cumambrin A의함량을 높이기 위해서는 인산의 시용보다 칼리의 시용이 더 요구되며, 야외포장에서의 인산과 칼리의 적정 시비량의 설정이 필요하다고 판단된다. To establish the fertilization condition to increase the productivity of Chrysanthemum boreale M. with high quality, the effects of three nutrients (N, P, K) on the yields and the effective components were investigated in the pot scale. NPK was applied by chemical fertilizers with N-P_2O_5-K_2O = 250-160-160 kg/ha as a main treatment, and NP (N-P_2O_5 = 250-160 kg/ha), NK (N-KO = 250-160 kg/ha), and PK (PO_2-KO_5 = 160-160 kg/ha) treatments were settled as comparison. Dry yields of C. boreale M. was increased significantly to 4 fold higher by nitrogen. Nitrogen increased apparently plant growth and inorganic nutrient uptake. In the flower, which is most useful and edible part as a herbal medicine, main amino acids were glutamic acid and aspartic acids, and the total content was increased significantly by three elements of application. In addition, the content of cumambrin A, which is known to have the effect of blood-pressure reduction, was increased source to 6.2 times by nitrogen higher than that in PK treatment. Potassium was more effective in biosyndiesis of cumatnbrin A than phosphorus, but the biological pathway was not clear, still.

        인삼 재배 예정지의 Arbuscular 균근균(AMF) 번식체 밀도 향상

        손보균(Bo-Kyoon Sohn),진서영(Seo-Young Jin),김홍림(Hong-Lim Kim),조주식(Ju-Sik Cho),이도진(Do-Jin Lee) 한국토양비료학회 2008 한국토양비료학회지 Vol.41 No.3

        대학 부속농장의 밭 토양을 선정하여 토양 중 AMF 밀도 향상과 토양 물리성 개선을 위하여 기주 작물로서 겨울작물인 보리와 호밀, 여름작물인 수단 그라스와 콩을 재배하는 작부체계 유형별로 AMF 밀도 변화와 토양특성을 조사하였다. 재배작물의 생산량은 겨울작물 중 호밀을 재배한 포장 (3,045.3 kg 10a<SUP>-1</SUP>)이 가장 높았으며, 호밀 재배 후 여름작물 중 수단그라스를 재배한 포장 (2,756.8 kg 10a<SUP>-1</SUP>)과 보리를 재배한 후 콩을 재배한 포장 (1,628.3 kg 10a<SUP>-1</SUP>) 순으로 건물 생산량을 보였다. 유기물 함량에서는 큰 변화는 인정되지 않았으나 입단화율은 보리를 재배한 포장이 45.7%, 호밀을 재배한 후 수단그라스를 재배한 포장에서 45.1%로 높아졌다. 포자밀도는 겨울작물을 재배한 포장이 전체적으로 증가하는 경향을 보였고, 여름작물은 수단그라스를 재배한 포장에서 건토 1g당 64개로 콩을 재배한 포장보다 증가하였다. AMF 외생균사 길이는 겨울작물이 건토 1 g당 1.5∼2.0 m 수준이었으며, 여름작물은 수단그라스를 재배한 포장이 건토 1 g당 2.6∼2.9 m, 콩을 재배한 포장이 건토 1 g당 1.7∼2.2 m 수준으로 대조구보다 높게 나타났다. 토양 중 Glomalin 함량은 작물을 재배한 포장이 대조구보다 높은 함량을 나타내었다. 그 중에서도 보리를 재배한 후 이어 콩을 재배한 포장에서 건토 1 g 당 1.7 mg로 가장 높게 나타났다. 이상의 결과에서 인삼 재배 예정지의 토양관리를 위한 작부체계는 겨울작물의 보리를 재배한 다음 여름작물의 수단그라스를 재배하는 유형이 AMF 포자밀도 향상과 토양 물 리성 개선에 효과적인 것으로 밝혀졌다. This study was carried out to improve density of arbuscular mycorrhizal fungi (AMF) propagule and physiochemical properties of soil by planting crops at the preplanning field for ginseng cultivation. Winter crops, such as barley and rye and summer crops, such as sudangrass and soybean were cultivated in combination to improve AMF propagation and soil aggregation at the fields. Yield of harvested crops by plating with winter or/and summer crops was 3,045 kg 10a<SUP>-1</SUP> of the only rye cultivation, 2,757 kg 10a<SUP>-1</SUP> of sudangrass cultivation in combination with rye growing (rye/sudangrass) and 1,628 kg 10a<SUP>-1</SUP> of soybean cultivation in combination with barley growing (barley/soybean), respectively. Soil aggregation rate was improved by cultivation with barley (45.7%) and with rye/sudangrass (45.1%), respectively. The density of AMF spores in soil was increased slowly by cultivating with winter crops. In summer crops cultivation system, density of AMF spores at sudangrass cultivated field was 64.0 spores g<SUP>-1</SUP> dried soil and it was higher than that at soybean cultivated field. External hyphae length (EHL) was 1.5~2.0 m g<SUP>-1</SUP> air-dried soil at winter crops cultivated field. However, in summer crops cultivation systems, EHL was 2.6~2.9 m g<SUP>-1</SUP> airdried soil at sudangrass cultivated field and was 1.7~2.2 m g<SUP>-1</SUP> air-dried soil at soybean cultivated filed, showing these were higher than those in non-cultivated field (control). Glomalin content of soil cultivated with crops was higher than that of control soil. Especially, the highest glomalin content was shown to 1.7 mg g<SUP>-1</SUP> air-dried soil in the barley/soybean cultivation systems. These results suggested that the most effective soil management to improve AMF propagule density and soil physical properties by planting crops system was cultivating sudangrass followed by barley at the preplanning fields for ginseng cultivation.

        전남지역 인삼재배 토양의 Arbuscular 균근균 분포 특성

        손보균(Bo-Kyoon Sohn),진서영(Seo-Young Jin),이도진(Do-Jin Lee) 한국토양비료학회 2008 한국토양비료학회지 Vol.41 No.3

        전남지역 인삼재배지의 토착 Arbuscular 균근균 (AMF)의 분포와 감염특성을 파악하기 위해 곡성, 영광, 영암, 해남 지역을 대상으로 58개 지점의 토양과 인삼 시료를 채취하여 조사하고 AMF 밀도와 토양특성을 조사하였다. 조사지역의 전체 평균 포자밀도는 건토 1 g당 3.4∼5.9개의 분포를 보였으며, 재배 연수 3년근 재배지까지는 포자밀도가 다소 증가하는 경향을 보였고, 자연상태 토양 중의 AMF 포자밀도는 건토 1 g 당 6.3∼14.7개로서 인삼재배지 보다 포자밀도가 높았다. 포자크기별 분포는 직경 45∼106㎛ 범위에 74.3% 정도가 포함되었으며, AMF의 감염 양상은 Paris-type이 주를 이루었다. 평균 감염율은 영암지역의 재배지에서 64.4%로 높게 나타났으나 그밖의 지역은 40∼50%범위를 보였다. 조사지역의 근권토양 중 AMF 외생균사의 길이는 건토 1 g당 0.5∼4.4 m 범위로서 인삼의 재배연수가 증가함에 따라 외생균사(external hyphae)의 양이 많아지는 것으로 파악되었다. This study was carried out to investigate the distribution characteristics, colonization patterns of arbuscular mycorrhizal fungi (AMF) at Ginseng- cultivated fields in Jeonnam province including Gokseong, Yeonggwang, Yeongam and Haenam area. Average density of AMF spores in all of analyzed areas was in the range of 3.4~5.9 spores g<SUP>-1</SUP> air-dried soil and spore density in the soil was increased gradually up to Ginseng cultivated fields grown for 3 years. However, AMF spore densities in the marginal field soil were 6.3~14.7 spores g<SUP>-1</SUP> air-dried soil and it was higher than those in Ginseng-cultivated field soils. A 45~106 in diameter of AMF spores by size was dominant (74.3%) in Ginseng cultivated fields. AMF colonization association type in Ginseng roots was a Paris-type. Average rates of AMF infection ranged from 40% to 50%, while 64.4% of AMF infection occurred in Yeongam area. External hyphae length (EHL) in the rhizosphere soil of Ginseng cultivated field was in the range of 0.5~4.4 m g-1 air-dried soil and the hyphae quantity was gradually increased proportional to increment of Ginseng cultivation years.
