토양훈증제 처리가 2년생 인삼의 생육과 화학적 조성에 미치는 영향
안용준,김요태,김명수,최승윤 한국응용곤충학회 1981 한국응용곤충학회지 Vol.20 No.1
D-D외 3종의 토양훈증제를 인삼의 연작토에 15cm, 30cm 깊이로 처리하였을 때 2년생인삼의 생육과 화학적조성에 미치는 영향을 알아보기 위해서 본 시험을 실시하였다. 1980년 3월 7일 처리, 4월 1일 이식, 8월 19일에 채취하여 근, 경, 엽으로 나누어 일반 무기성분(N, P, K, Ca, Mg, Na, Fe, Mn, Zn)을 분석한바 그 결과는 다음과 같았다. 1. 훈증제처리가 2년생인삼의 지상하부의 생육을 촉진하였는데, 지하부 생체중의 경우 , 건물중의 경우 증가하였다. 2. 지상하부의 질소와 인산의 함량은 훈증제처리구에서 무처리구에 비하여 증가하였으나, a의 경우에는 오히려 감소하는 경향을 보였다. K의 경우에 있어서는 지하부에서는 함량이 감소하였으나, 지하부에서는 증가하였다. 3. 미량요소의 경우에 있어서는 Mn, Fe의 함량은 훈증제처리구에서 증가하였으나, Na, Zn의 함량에는 큰 영향을 미치지 못하였다. 4. 훈증제의 처리깊이(15cm, 30cm)에 따른 차이에서 보면 2년생인삼의 생육과 화학적조성에는 별다른 차이를 볼 수 없었다. These experiments were conducted to investigate some effects of the soil fumigants Dow-fume MC-2, Cylone, TeloneC-17, and D-D on the growth response of the Korea ginseng(two-year old), Panax ginseng C.A. Meyer, and the chemical composition of the plants. Fumigant treatment increased growth of roots, stems, and leaves. The increase of root growth rates ranging from 2.8 to in fresh weight and 8.1 to in dry weight were observed in the 2-year old ginseng plants grown in the old ginseng soil treated with the different soil fumigants. The chemical analysis of inorganic elements such as N, P, K, Ca, Mg, Na, Fe, Mn, and Zn was made for the roots, stems and leaves of the 2-year old plants. The increases or decreases of content of the elements were observed, and their contents of each of the elements were changed with the kind of fumigants, part of the plants, and soil depth of the fumigant treatments, but their changing tendencies were not steady.

This study was carried out to investigate the effect of different soil moisture contents on the growth and chemical constituents of burley tobacco and on the protein pattern in tobacco leaf. Height, stem diameter, and largest leaf length of tobacco droughted from 45 to 60 days after transplanting was not recovered by rewatered amount of water supply from 60 to 75 days after transplanting, but leaf width enlarged. Dry weight per unit leaf area and total nitrogen content showed high values in low soil moisture, but total alkaloid contents were not different according to soil moisture contents. Soil moisture content didn't effect on the protein pattern of middle and upper leaves, but lower leaves showed the mild color and fewer numbers of the protein bands than those of midd1e and upper leaves.
거세미나방 유충에 대한 Carbofuran·Diazinon혼합의 연합독작용
안용준,김요태,김홍진,최승윤 한국응용곤충학회 1980 한국응용곤충학회지 Vol.19 No.2
Carbofuran (2,3-Dihydro-2,2-Dimethyl-benzofuranyl methyl carbamate)와 Diazinon (0,0-Diethyl-0-(2-isopropyl-4-methyl-6-pyrimidinyl) phosphorothioate)을 10:0, 9:1, 8:2, 7:3, 6:4, 5, 5, 4:6, 3:7, 2:8, 1:9, 0:10의 비율로 혼합하여 거세미나방 3냉기유충의 가운데 가슴등판에 1.0μl씩 국소처리 하였을 때, 이들의 연합독작용을 평가하였다. Carbofuran Diazinon을 혼합하였을 경우 거세미 나방 3령기유충에 대해서 협력작용(Synergism)을 나타내었으며 Carbofuran과 Diazinon을 4.8 : 5.2의 비율로 혼합하였을 때 최대의 협력효과(Synergistic effect)를 얻을 수가 있었다. Some experiment were conducted to evaluate the joint toxic action of carbofuran(2,3-Dihydro-2, 2-dimethyl-benzofuranyl methyl carbamate) and diazinon (0.0-Diethyl-0-(2-isopropyl-6-methyl-e-pyrimidinyl)-0-thionophosphate) against 3rd-instar larvae of the common cutworm, Agrotis fucosa (Butler). Acetone solutions of carbofuran or diazinon or mixture of these two insecticides, were topically applied to the mesonotum of the insect in a constant volume of 1.0μl per larva by means of Burkard microapplicator. Joint toxic action of carbofuran and diazinon for 3rd-instar larva of common cutworm was synergistic. The maximum synergistic effect might be obtained when the ratio of carbofuran to diazinon was 4.8 : 5.2.

This study was carried out to develop a new stalk curing of the horizontal hanging method that would reduce the harvesting and curing labor, and improve its quality of cured leaf than the conventional stalk curing method in burley tobacco. The horizontal hanging stalk-curing method designed from 1988 was compared with the conventional method. The horizontal method shortened the curing Period for 7 days and reduced to 0.3%, while it occurred 9.4% in the vertical method. In the horizontal method, the quality of cured leaf improved 9%, but the contents of chemical components and physical properties were similar to those of vertical method. The labor of stalk-cut and loading in curing facility reduced 28% by the horizontal method. In harvesting and curing process, the horizontal method resulted 12% of labor saving as compared with the vertical method. Key words : horizontal hanging stalk-curing method, vertical method, stalk-curing.
