최범렬,조재성,이종철,Choi, B.Y.,Jo, J.S.,Lee, J.C. 충남대학교 농업과학연구소 1976 Korean Journal of Agricultural Science Vol.3 No.1

만식재배(晩植栽培)에 알맞는 묘대양식별(苗垈樣式別) 육묘일수(育苗日數)를 구명(究明)코져 유신(維新)과 조생통일(早生統一)을 공시(供試)하여 6월(月) 25일(日)에 이앙(移快)하여 본(本) 시험(試驗)을 실시(實施)하였던바 다음과 같은 결과(結果)를 얻었다. 1. 비닐보온육묘(保溫陸苗)가 비닐보온절충묘(保溫折衷苗)에 비(比)하여 분얼수(分蘖數) 및 수수(穗數)가 많았으며 육묘일수간(育苗日數間)에는 육묘일수(育苗日數)가 긴 것일수록 많았다. 2. 유신(維新)은 묘대일수감응도(苗垈日數感應度)가 작아서 묘대양식(苗垈樣式) 불구(不拘)하고 육묘일수(育苗日數) 60일(日)에서도 불시출수(不時出穗)가 없었으나 조생통일(早生統一)은 비닐보온절충묘대(保溫折衷苗垈)에서 육묘일수(育苗日數) 50일(日) 이상(以上)에서 불시출수(不時出穗)가 나타났고, 비닐보온육묘(保溫陸苗)에서는 60일(日)까지도 불시출수(不時出穗)가 나타나지 않았다. 3. 불시출수(不時出穗)가 조장(助長)되지 않는 묘대환경하(苗垈環境下)에서는 조파(早播)에 의(依)하여 출수촉진(出穩足進)의 효과(效果)가 있었으며, 기중(其中) 조생통일(早生統一)이 유신(維新)보다 현저(顯著) 하였다. 4. 주당수수(株當穗數)는 비닐보온육묘(保溫陸苗)가 비닐보온절충묘(保溫折衷苗)보다 육묘일수(育苗日數)에 관계(關係)없이 증가(增加)되었다. 5. 수량(收量)은 양(兩) 품종(品種) 공(共)히 비닐보온육묘(保溫陸苗)에서 많았으며 육묘일수간(育苗日數間)에는 비닐보온절충묘(保溫折衷苗)에서는 40일묘(日苗) 비닐보온육묘(保溫陸苗)에서는 60일묘(日苗)에서 양(兩) 품종(品種) 공(共)히 증수(增收) 되었다. This experiment was carried out to determine the most adequate type and period of nursery for the late seasonal cultivation of the new varieties of rice, Yusin and Josaengtongil. The results obtained are summarized as follows: 1. Semi-hot up-land nursery was much effective for the increase of the number of tillerings and the roots of rise seedlings compared with the semi-hot low-land nursery. The number of tillerings and roots was increased in 60 days seedlings compared with 50 or 60 days seedlings. 2. The abnormal heading has not appeared at the variety Yusin at all. The seedlings of Josaengtongil grown over 50 days at the semi-hot low-and nursery showed the abnormal heading, but the abnormal heading was not checked out at the seedlings of same variety grown for 60 days on the semi-hot upland nursery. 3. On the nursery not to cause the abnormal heading, earlier seeding was much effective for the hastening of the heading time and the hastening effect of heading time by earlier seeding was significantly greater at the variety Josaengtongil than Yusin 4. The number of ears per hill was significantly increased in the seedlings from the semi-hot up-land nursery compared with the semi-hot low-land nursery. 5. When the growing period of rice seedlings was not considered, the semi-hot up-land nursery resulted in higher yield of rice than the semi-hot low-land nursery. Considering the growing periods of rice seedlings, 40 days seedlings showed high yield at the semi-hot low-land nursery, however, at the semi-hot up-land nursery, 60 days seedlings showed higher yield of rice.

최범열,박종성,김영래,김문규,조재성,김충수,Choi, B.Y.,Park, J.S.,Kim, Y.R.,Kim, M.K.,Jo, J.S.,Kim, C.S. 충남대학교 농업과학연구소 1975 Korean Journal of Agricultural Science Vol.2 No.1

재식위치(栽植位置)에 따른 인삼(人蔘)의 주요량적(主要量的) 형질(形質)의 변이(變異)를 구명(究明)하고 형질상호간(形質相互間)의 관계(關係)를 구명(究明)하기 위(爲)하여 4열(列) 6열(列) 및 8열재식포장(列栽植圃場)의 인삼(人蔘)을 조사분석(調査分析)하였던바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1. 지하부(地上部)의 생육(生育)(엽장(葉長), 엽폭(葉幅), 경장(莖長), 경태(莖太))은 6열(列) 및 8열구(列區)에서 도두 전열(前列)과 저조(低調)한 결과(結果)를 나타내었던 반면(反面) 지하부(地下部)의 생육(生育)(근경(根長), 근직경(根直徑), 근종(根種)은 전열(前列)에서는 오히려 우수(優秀)하였고 후열(後列)에서만 저조(低調)한 결과(結果)를 보였다. 그러나 4열구(列區)에서는 지하부(地上部) 및 지하부생육(地下部生育) 모두 전열(前列)에서 우수(優秀)하였고 후열(後列)에서는 현저(顯著)히 불량(不良)하였다. 2. 6열재식구(列栽植區)의 평균근중(平均根重)은 34.2g인데 비(比)해 8열재식구(列栽植區)는 18.2g으로서 전체수량은 6열재식구(列栽植區)가 8열재식구(列栽植區)에 비(比)해 현저(顯著)히 높았으며 품질(品質)도 좋았다. 3. 재식위치(栽植位置)의 차이(差異)에 따르는 변이(變異)는 8열재식(列栽植)의 경우(境遇)는 경태(莖太)가 가장 작은 변이(變異)를 보였고 근장(根長)이 가장 큰 변이(變異)를 보였는데 6열재식(列栽植)의 경우(境遇)에서는 엽폭(葉幅)이 가장 작은 변이(變異)를 보였고 경장(莖長)이 가장 큰 변이(變異)를 보였던 반면(反面) 4열재식구(列栽植區)에서는 엽장(葉長)에서 가장 작은 변이(變異)를 그리고 근중(根重)에서 가장 큰 변이(變異)를 보였다. 4. 각재식밀도(各栽植密度)에서 대체로 근중(根重)과 가장 높은 유의상관(有意相關)을 보였던 형질(形質)은 근직경(根直徑)이었으며 또한 근직경(根直徑)과는 경태간(莖太間)에서 높은 상관(相關)을 보였다. 5. 재식위치(栽植位置)에 따라하 각형질(各形質)에서 개체간의 변이정도(變異程度)는 현저(顯著)히 다른 경향(傾向)을 보였으며 형질(形質) 상호간(相互間)의 상계(相係)로 재식위치(栽植位置)에 따라 상관(相關)의 정도(程度)가 서로 다른 경향(傾向)을 보였다. This study was carried out to define the variations of important quantitative characters and correlations among them accoding to the planted location under the shadow by planting density. The results obtained are summarized as follows; 1. Growth of leaf and stem of 6 rows and 8 rows planting plots was decreased at front and back rows, but that of root was increased at front row and also decreased at back row. However, at 4 rows planting plots, front row was better for the growth of leaf, stem and root. 2. Average root weight of 6 rows planting plot was 34.29g but that of 8 rows planting plot was ]8.20 g. And total weight of root per unit area was increased and quality of ginseng was better in 6 rows planting plot compaired with 8 rows. 3. Variation by planting locations under the shadow was smallest in stem diameter and highest in root length at 8 row planting plot, but at 6 rows planting plot, that was smallest in leaf blade and greatest in stem length. However, in 4 rows plant ing plot, variation of leaf length was smallest and that of root weight biggest. 4. In all Planting densities, root weight was significantly correlated with root diameter and high correlation was recognized between root diameter and stem diameter. 5. Rate of variations of all characters among plant individuals was different by planting location and that of correlations between quantitative Characters too.

충남지방(忠南地方)의 답이용도(沓利用度) 제고(提高)를 위(爲)한 기초정보(基礎情報)를 얻기 위(爲)하여 충남(忠南)의 입지적(立地的)인 조건(條件)과 아울러 답이용현황(沓利用現況) 및 답이용도(沓利用度)의 제고(提高)를 조해(阻害)하는 요인(要人)을 분석(分析)하고 보다 생산성(生産性) 높은 작업(作業) 및 경종체계를 모색(摸索)하였던바 결과(結果)를 요약(要約)하면 다음과 같다. 1. 답전후작(沓前後作)을 기피(忌避)하는 일차적(一次的)인 원인(原因)은 논의 배수불량(排水不良)이었고 이차적(二次的)인 원인(原因)은 이앙기(移秧期)에 지장(支障)을 초래(招來)한다는 점(点)이었고 삼차적(三次的)인 원인(原因)은 노동력(勞動力) 부족(不足)이었다. 2. 답전후작(沓前後作)을 수행(遂行)하는 농가(農家)는 대부분영세농(大部分零細農)으로서 자가식량(自家食糧)을 대보를 위(爲)한 소규모재배(小規模栽培)가 많았으며 주작목(主作目)은 보리였다. 3. 충남(忠南)의 기조적(氣條的)인 조건(條件)을 고려(考慮)할 때 대체로 답전후작물(沓前後作物)의 수확기(收穫期)는 6월(月)10일(日)이 한계(限界)이며 수도(水稻)의 이앙기(移秧期)는 6월(月)25일(日)이 한계(限界)이다. 4. 답전후작(沓前後作)으로 보리를 파종(播種)할 경우(境遇) 경운전(耕耘前) 로타리살파(撒播)가 가장 능률적(能率的)이었을 뿐아니라 적은 경비(經費)가 소요(所要)되었다. 5 소득(所得)과 아울러 수확(收穫) 및 이앙작업소요기간(移秧作業所要期間)을 고려(考慮)할 경우(境遇) 일반적(一般的)으로 조생(早生)통일+올보리의 작부방식(作付方式)이 유리(有利)하였다. To obtain the informations on the checking factors of the effecient utilization of paddies in chungnam province and study on the effecient working system and high productive cropping system in paddies, the utilization state of paddies including environmental conditions were investigated at sample 1,500 farms. The results obtained are summarized as follows; 1. The difficulty of drainage in paddies was the most important factor checking the utility of paddies. Delayed transplanting of rice and lack of labour were also important checking factors on the efficient utilization of paddies. 2. The utilization of paddies was rather effecient at small size farms of which farmers were almost poor, and most of them cultivated barley for their own food. 3. Considering climatic conditions, pre-crops of rice must be harvested before June 10 tho and the marginal transplanting date of rice plant is June 25 th. 4. In case of planting barley as a post-crop after rice, the spread seeding by rotary before plowing was most efficient with lowest cost. 5. Considering rice cultivation, yield of barley and net income, the most efficient cropping system was "Josaengtongil + Olbori".
