最近 全國的으로 高調되어가고있는 水稻의 早植動向을 改良法으로 改革시키는 일은 米穀의 安定多收와 展開的 營農改善에 奇與할 수 있는 最大의 技術改革의 하나라고 生覺된다. 京畿道를 中心으로 하는 安城地域의 水稻早植裁培에 適應할 수 있는 育苗型을 究明하기 爲하여 實驗硏究한 結果를 要約하면 다음과 같다. (1) 早期(植)裁培에 使用할 育苗型은 一般的으로 포리에치렌 被??保溫折衷苗垈보다 優秀하였다. (2) 極早期裁培區(3.20)에서는 田苗垈가 苗의 生育이 優秀하고 品種間에는 普通晩生種인 農林29號보다 陸羽 132號가 健苗였다. (3) 標準早期裁培區(4.1)에서는 苗垈型에 큰 差異가 없으며 品種間에도 큰 差異가 없으므로 이 地方에서 4月1日 以後에 播種한다면 管理가 不便하고 費用이 많이드는 田苗垈보다 保溫折衷苗垈도 損失이 없고 早晩의 品種間에도 큰 差異가 없는것으로 推察된다. (4) 準早期裁培區(4.20)에서는 田苗垈보다 保溫折衷苗垈區에서가 苗의 生育이 良好했고 早晩의 品種間에는 普通晩生種인 農林29號가 早生種인 陸羽133號에 比해서 健苗였다. (5) 乾物重/草長의 값이 큰것일수록 移秧後 1株의 最高分??數가 增加하였으며 極早期裁培區에서는 田苗垈, 準早期裁培區에서는 保溫折衷苗垈에서 이 數値가 높았다. 또한 早晩의 品種間에도 前者는 早生種 後者는 晩生種이 값이 높았다. Recently the early transplanting cultivation of rice crops which is widespread in south Korea, may be considered to bring about a technical renovation of the methods of rice growing that will be able to contribute to the steady prolific yield of rice and improved managment of paddy field. The purpose of the present study is to investigate the type of nursery bed by the seed time for the early transplanting tin the An Sung-Kun central areas of he Kyung Ki-Do. were conducted to be set up and are summarized as follows. (1) Nursery beds for the ultra early transplanting of rice culture, generally the upland nursery beds with polyethylen sheet convert are superior than semi -hot nursery beds with polyethylen sheet cover. (2) In the ultra early sowing plot (March 20th ), upland nursery beds are superior than Semi -hat nursery beds nd the early maturing variety You -Ku No 132 could be produced healthy seeding than the common late maturing variety Nong -Rim No 29. (3) In the standard early sowing plot (April 1St). there were no significant difference in seed growing by the styls of nursery beds and varieties. If the sowing may be conducted at this rigion after April 1st, Semi - hot nursery bed are by no means inferior to comprison with the growing on upland beds which is inconvenient and much expendes. there were no significant differences for growing between two varieties are observed. (4) In he quasi - early sowing plot (April 20 th ). semi- hat nusery beds produced healthy seeding than those of upland nursery beds. Common late maturing variety Nong -Rim No 29 produced better healthy seeding than the early maturing variety You -Ku No. 132 (5) when the value of the dry weight of seedling lenght are high much tillered its seedling after transplanting this value are high on uplanad nursery beds in the ultra early sowing plot and on semi - hat nursery beds in the quasi -early sowing plot also early maturing variety in the quasi -early sowing plot showed high values of this figure.

馬鈴薯의 塊莖形成肥大에 關한 硏究

This experiment was conducted with general process of tuberization and its relation to plant growth in order to investigate morphological observation on the tuber development of potato plant at the national An-Sung agricultural Jurnior College from 1982-1984. The results obtained are summarized as follows: 1) It is generally known that morphological observation on the tuberization of the potato plant, namely relation of environmental conditions, high-temperature supply, soil temperature and length of day light period. 2) According to an observation of growth process of the material plant, the process of tuberization was divided 4 periods as already reported "solon elongation period," "tuber formation period," tuber enlargement period" and "tuber completion period." 3) In short, an investigation was made to trace the developmental change of larger and smaller tubers during "tuber enlargement" and "tuber completion period". What is here called "larger tubers" denotes those tubers which were comparatively larger at successive stage of planes growth. The so-call "smaller tubers" are those which were as constant as possible in weigh during every succive stage, weighing 30-40 grame. 4) The results so far mentioned induce one to conclude that, in the potato plant, which physiological character is regulated a periodical factor during the process of tuberization. It has been suspected that the cause of differentation of tuber, in the same potato plant, into different weigh is either quantitative difference of growth rate in tuber enlargement period or a difference in growth stopping stage. The author should like to support the former, because, as my research has proved, the change in composition is regulated essentially by a periodical factor. 5) At least the mother tuber in potato relates of very great to first growth of aerial part till a stage of changing point of growth-rate and before tuber enlargement period, and afterthat the mother tuber stores water till its callapse, but the watter storage is suppose to be only a phonomena with secondary significance among roles of mother tuber. 6) The stolon emerges extrophy from the node of subterrenean main stem at once after germination. The writer described that the emergence of stolon would be induced by the differentation of flower organ in the growing point of the terrestrial main stem. The vascular bundle of stolon develops weakly and scarcely in comparison with the main stem.

沓裏作栽培의 滯水時期別 濕害가 大麥의 生育과 收量에 미치는 影響

This experiment was conducted to determine the effect of various soil in "excess-moisture injury " levels on top and root growth of barley and its yield. Barley(variety Su-Won No.18) was grown on a diluvial clay loan soil at Plant beeding farm (Pot cultivation) in every season during 2 years (1982-1983) at the experimental farm of National An-Sung Agricultural Juniot College. I investigated the relation between the growth times the stage of moisture, by keeping the water below the surface of the soil into pot by 10cm, for 7 days every 5times treatment immediately after sowing. In order to fine out some morphological characteristics of root growth related to the resistance of excess-moisture injury. I have undertaken to charify the mechanism of "excess-moisture injury in barley cultivation of drained paddy field soil. the result of this experimental showed that the harm done to the growth and the harvest was remarkable result in this studies are summariged as following 5 stages (infant-nursery-bed period, tilling-peak period, very-young-head forming period, expensione growth period and sprouting period) (1)Excess-moisture injury in winter:- The visual symptoms of excess-moisture injury appear already, thought gradually, in January, when the soil moisture is too high and probably the oxygen supply to the root is restricted, for example in case of barely plant stunted in growth and shows yellowish or brownish color leaves followed by drying of terminal portions of the leaves. The root system becomes more restricted and less fibrous, dark in color and its growth is suspended. Anatomical observation showed that the brownish color of the injured root, especially at the root tips, is attributed the necrotic change in the rot cells. Another change in the injured root is the cospicuous ligification in stele and endodermal cells of the root, and also the same phenomena goes on step by step in the cortical and epidermal cells including root-hairs. It became clear that the stiffness of the injured root may be ascribed to the lignification of the root tissues. But, in this season even wet in wet soil, any physical and chemical changes which may affect the plant growth were not seen, this may be due to the low temperature (around 5℃) of the soil in which the microbial activities are restraind and the subsequent maintenance of high redox-potentials of the soil. so the injury of this period mainly due to the poor aeration around the root, regardless of the changes of soil conditions. (2) Execess moisture-injury in spring and summer:- When the temperature of the soil rises up to 8-10℃ or higher, then all of a sudden plants come to be seriously injured. That is, the stunted growth, yellowish or brownish green color of young leaves and withering of older leaves are notable features at the time. The root system developed poorly: Seminal roots were injured showing necrotic changes and the crown roots stoped their growth owing to the death of their tips, and rapid lignification of the root cells was recognized as described. In this period, besides the necrotic changes or lignification of the root, inorganic iron was detected abundantly in rot tissues, particularly at the root tips, while in the healthy ones such substance could not be seen. If the temperature rises furthermore, black depositions are seen here and there on the surface or inner parts of the roots. This deposition was confirmed to be the product of Fe^++ and S" coming separately into the roots from the wet soil. Author recognized the essential differences between the characteristics of the soil in this period from those of the soil in winter. That is, the soil in this period shows low redox-potentials and Fe^++ and S" are formed to such an extent as seems harmful to the plant. It was also ascertained that those harmful imgredients will intrude casily into the root tissue and act as poisons within it. Beside necrotic change of lignification of the root cell, histological change occurs in the root, namely the formation of intercellulary cavities due to the Lysigenous rupture or dissolution of the cortical cells. (3) Resistance of plant against high soil moisture and the degree of development of air conducting system:- According to the present investigation, Author reached to the conclusion that, in the barley plant which has a strong resistance against excess moisture, the oxygen needed for root respiration will be mainly sent from the leaf via stem 10 the root, whereas in the weak plant, oxygen is supplied directly to the root from the air in the soil. And the tolerability of plant to anaerobic condition of the soil may be attributed to the degree of transporting power of oxygen from the top to the root. The structural differences seen in conducting tissues between upland and swamp plant, especially in the cortex of the root, strongly endorse the above view. Namely, in the submersion the air conducting tissues are well developed and consequently air transporting power from the aerial part to the root seems to be superior to the latter. (4) Tolerability of plant to the high moisture of the soil and the redox-potentials of the soil:- Author testified that the lowering of redox potentials of the wet soil around the roots leads to low potentials of the root cells, and in the case of barley, this promotes the lignification of the root cells, and the resulted lignin defends the intrusion of reduced poisoning ingredients. According to the above fact, Author came to the conclusion that the lignification in the root as in barley root or the formation of intercellular spaces in the cortex of plant root may have to be considered a "Adaptation" against the unfavourable circumstances such as poot aeration around the root. (5) In over-moist soil conditions, plant diminishes the water absorbing power. It was considered that the withering and etiolation of leaves in wet soil, are partly due to the weakened absorbing power of nutrient water. Furthermore author tested the changes of activities of Oxydation Reduction enzymes (Fe-Enzymes) such as Peroxydase and catalase in the roots of barley which were grown in overmoist soil, and ascertained that the activities of oxydase was declined, on the contrary, the activities of catalase was promoted. The change of activities of such enzymes in the roots are presumed to lower the redox-potentials of the root cells, and the lowering of redox-potentials in likely to accelerate the lignification of the tissues. (6) According to the experimention all the plants Examined, regardless of upland and swamp plants, withered when they are left under strongly reduced soil conditions, though the duration is notable different. Substantial differences were not therefore found about the mechanism of the injury between upland and swamp plant. As far as Author experiment concerned, "excess=moisture injury" did not occur, if the osil around the toots has 30 percent or more air spaces, even much decomposable organic matter existed in the soil. This also was ascertained in the field. (7) On way of the present experiment, author found that in Juncaceae or Iridaceae, which have remarkable tolerability against excess moisture, root hairs are strongly lignified. With this lignified root hair, the meaning of its existence is not yet clear as it was not studied thoroughly. But it was ascertained that lignification of root-hairs also occurs in barley like the plants just mentioned, when they are put under swamp conditions. This presumed to be a strengthening of excess-moisture tolerability, that is a kind of adaptation of the plant which are originally weak against excess moistured soil conditions.

This studies were conducted to define the effect of the orginal scripture and the chiness classics which were Chun-Bu-Kyongs and Jo-Wha-Kyong since the beginning of the world. this experiment were carried out in the principles of harmony and the wonders of nature which were inquire in to the principles of the cosmic duel forces (Tai-Geuk) from prehistoric times to the present, the results obtained are Summarized as follow: 1. In the beginning was the word and the word was with God and the word was God, all things were made through him and without him was not anything made that was made in him was life and the life was the light of men. the light Shines in the darkness and the darkness has not overcome it. 2. The first man was from the earth, a man of dust. the Second man is from heaven as was the man of dust, So are those who are of the dust and is the man of heaven. So are those who are of heaven just as we have borne the image of the man of dust we shall also hear the image of the man of heaven. 3. For as woman was made from man, So man is now born of woman and all things from God. for man was not made from woman but woman from man neither was man created for woman but woman for man nevertheless in the God. woman is not independent of man nor man of woman. 4. Th Lord God formed the man from the dust of the ground and breathed into his nostrils the breath of life and the man became a living being. this is the account of the heaven and the earth. 5. In the beginning God created the heavens and the earth. now the earth was formeless and empty, darkness was over the surface of the deep and the spirit God was hovering over the water. 6. God said let there be light and there was light and he saparated the light from the darkness God calld the light day and the darkness the called night. God saw that light was good. 7. god said let there be an expanse between the water to separate water from water. So God made the expanse and separated the water under the expanse from the water above it. and God called the expanse sky. 8. God said let the water under the sky be gathered to one place and let dry ground appear and God called the dry ground land and the gathered waters be called seas and God sow it was good. 9. God said let there be light in the expanse of the sky to separate the day from the night and let them serve as signs to mark season and days and years and let them be light in the expanse of the sky to give light on the earth and it was so. 10. God made two great light the greater light to govern the day the lesser light to govern the night. he also made the stars. God set them in the expanse of the sky to give light on the earth, to govern the day and the night and to separate light from darkness. 11. God said let us make man in our image in our likeness and he created man in his own image, in the image of God. he created him male and female he created him. and God blessed them and said to them. to fruitful and increase in number fill the earth and subdue it. thus the heavens and the earths were completed in all their vast array.

본 연구에서는 1200℃의 저온에서 침상형 뮬라이트를 합성하고, 이러한 침상형 뮬라이트를 생성하는 메카니즘을 관찰함과 동시에 메카니즘을 활용한 제어된 미세구조를 가진 뮬라이트를 합성하고자 하였다. Al원으로 사용되는 원료로서는 Al(OH)_3를 사용한 경우가 Al_2O_3를 사용한 결과보다 더욱 발달된 휘스커상의 뮬라이트를 얻을 수 있었다. 각 온도구간에서 열처리한 시편은 미세구조 관찰과 상분석을 통하여 플루오르토파즈와 휘스커상의 뮬라이트의 생성을 관찰하였으며, 토파즈상을 거쳐간 휘스커 뮬라이트의 생성은 하나의 토파즈 상에서 여러 방향으로 휘스커상의 뮬라이트가 성장되는 것을 관찰할 수 있었다. 1200℃에서 생성된 휘스커상의 뮬라이트는 [001] 방향으로 성장하였으며, (110)면의 면간거리는 5.34Å이었다. 과량의 Al(OH)_3를 참가하였을 경우 기존의 8:7:4 원료조합보다 11:7:4의 경우에 조대한 단일상의 휘스커 뮬라이트를 관찰할 수 있었으나, 그 이상의 Al(OH)_3의 첨가는 미반응 Al_2O_3로 인하여 단일상의 뮬라이트를 얻지 못하였다. Whiskered mullites were synthesized at relatively low temperature of 1200℃, and mullite forming mechanism was studied in this experiment. Al(OH)_3 as a raw materials was better in getting whiskered mullite than Al_2O_3. Microstructure and phase analysis were done for the specimens heat treated at various temperatures. It was found that the synthesized mullite had grown to [001] direction, and that the distance of (110) plane was 5.34Å. Al(OH)_3 addition resulted in larger mullite whisker than normal 8:7:4 ratio, but excessive Al(OH)_3 didn't affect the growth of mullite whisker.

보리의 濕害에 關한 硏究

沈一用 안성산업대학교 1985 論文集 Vol.17 No.-

地下水位의 高低에 依한 여러 가지 土壤濕害가 보리의 生育 및 收量에 미치는 影響을 調査하기 爲하여 4年間에 걸쳐서 皮?? 水原18號 使用한 pot實驗結果를 要約하면 다음고 같다. ① 主要生育時期의 滯水處理回數가 보리의 生育 및 收量形質에 미치는 影響에서는 보리의 生育中 어느 時期에 處理하여도 滯水處理를 當한 區는 無處理區에 比하여 生育은 顯著히 抑制되었으며 處理回數가 增加하면 할수록 生長은 점점 더 抑制當했다. 特히 穗孕期의 被害가 가장 컸으며 다음은 伸張期 및 出穗期의 順으로 收量減少를 招來했으며 5日間의 出穗遲延을 招來하게 되었다. ② 滯水處理에 依한 보리의 濕害는 冬季의 濕害보다도 生育이 旺盛한 春季의 濕害가 더 크게 出現되었으며 營養生長期보다도 生殖生長期에서 더 크게 生長 및 收量이 激減되었다. ③ 主要 生育時期別 滯水處理 日數가 보리의 生育 및 收量에 미치는 影響에서는 處理日數의 多少에 따라 增減의 差가 發生하였으며 보리 一生中에 穗孕期에 가장 被害가 컸고 幼苗期때가 가장 被害가 輕하게 出現되었다. ④ 地下水位의 高低가 보리의 生育 및 收量에 미치는 影響에서는 地下水位가 10cm區에서 被害가 最大로 出現되었으며 다음은 20cm, 30cm 및 40cm區의 順으로 生育 및 收量의 被害가 漸次로 輕減되었으며 6日間의 出穗遲延을 招來하게 되었다. ⑤ 地下水位의 高低에 依한 보리의 成分分析 結果에서는 亞酸化鐵(Fe^++)망간등이 地上部인 莖葉보다도 地下部인 根에 더욱 많이 含有되었으며 窒素燐酸 等은 根보다도 莖葉에서 더 많이 含有되었다. 따라서 土壤의 酸化還元電位(Eh)는 地下水位가 낮을수록 낮게 나타났다. ⑥ 滯水處理에 依하여 濕害를 當한 區는 無處理區에 比하여 地上部의 莖葉이 靑綠色이었던 것이 黃褐色으로 變했으며 地下部인 根端細胞도 乳白色에서 暗褐色으로 漸變하면서 及其也는 黑褐色으로 變하게 되어 濕害樣象이 더욱 크게 出現하게 되었다. ⑦ 地下水位가 낮을수록 滯水處理에 依한 地下水位가 높은 곳에 比하여 葉綠素의 含量이 增加되었으며 더욱 靑綠色을 나타내고 있었으며 呼吸作用 및 光合成量도 增加되고 있었다. 따라서 根活力도 더욱 旺盛하게 作用하였으며 氣孔의 開閉運動이 活潑히 作用하고 있었다. ⑧ 滯水處理에 依한 地下水位의 高低差에 따라 土壤內의 質的變化를 招來케 되었으며 其 結果 pH 및 Eh의 低下는 地下에서 크게 作用되었다. 따라서 根에 木化가 進行하게 되었으며 地下水位 10cm 區에서 가장 크게 나타났고 다음은 20cm, 30cm 및 40cm 區의 順으로 根의 木化(lignification)가 漸漸 더 激甚하게 進展되면서 及其也는 根의 壤死를 招來시키고 있음이 鏡檢에서 나타나고 있었다. ⑨ 滯水處理에 依하여 濕害를 當한 區는 無處理에 比하여 初期生育은 旺盛한 便이었으나 어느 限度를 지나면 漸次로 生育이 衰退하게 되며 生育 및 收量이 漸減되어지고 있었다. ⑩ 滯水處理에 依해 濕害發生의 主因은 土壤內의 通氣不良에 따른 酸素供給이 不圓滑해짐으로써 土壤內의 質的變化를 招來케 되므로 因하여 有害한 還元生産物의 生成과 炭酸gas의 生成등이 根의 生育에 被害를 주게 되었으며 이것들이 根에 吸收됨으로써 根에 木化(lignification)가 進行하게 되면서 結局은 壤死(Necros)하게 되었다(사진 10) This experiment was conducted to determine the effects of various soil in excess-moisture injury upon the underground watter level of barley and studies on the damage due to excessive watter in the soil of barley cultivated on the plastic pot in every season during 1982 to 1985. the results obtained are summarized as follow: (1) From the studies on the effects of times of sub-mersion on the vegetative growth and yield characters, the following results were obtained, the barley plants were damaged sub-merged soil during plats growth, the degree of damage was increased as the times of watter sub-mersion were increased, especially the plants which were sub-merged during head sprouting period were severely damaged and next severe damage was occured when plants in expension growth period and heading period were sub-merged. (2) The excessive watter damage due to sub-mersion was greater during the winter season than during the spring season, the plant growth was greatly retarted and yield was also highly reduce when plants were sub-merged during reproductive growing period compare to the plants sub-merged during vegetative period. (3) From the studies on the effects of days of watter sub-mersion during the growing periods, the following results are obtained the plants growth were greatly retarded as the days of watter sub-mersion extended and the most severe damage was observed when the plants in gead sprouting period were sub-merged, the lightest damage was observed when the plants infantnursury-bed period were sub-merged. (4) Ffrom the studies on the effects of under-ground watter levels on barley growth and yields, the following results were obtained, the damage due to the underground watter levels was least in 10cm of watter levels, the degree of damage was in the order of 20cm, 30cm and 40cm. (5) The leaf and stem color of plants subjected to excessive brown and-the roots color changed to from white cleam color to dark brown. (6) Under condition of high under-ground watter level the Fe^++ and Mn was higher in the root and N.Pand K were found more in the stems and leves, the soil Eh was low when the underground watter level was low. (7) The chlorophyll contant was increased as the under-ground watter levels get higher, the same was true for the respiration and photosynthesis rate therefore the root activities and stomato opening were greatly influenced by the under-ground watter levels.
