Objectives: This study aimed to examine the changes in ingredients according to its cultivation method by examining the content of saponin and non-saponin components of ginseng. Methods: Ginseng saponin component analysis was compared and reviewed using the high-performance liquid chromatography method, and acidic polysaccharide component was measured using the carbazole sulfuric acid method. Results: The comparative analysis of ginseng saponin content of 4 and 6 years old fresh ginseng showed the following results. According to the cultivation method, upland field cultivation fresh ginseng showed higher average content of crude saponin than paddy field cultivation fresh ginseng. Whereas, paddy field cultivation fresh ginseng showed higher average content of total saponin than upland field cultivation fresh ginseng. Ginsenoside Rb1 showed higher content of paddy field cultivation fresh ginseng than upland field cultivation fresh ginseng in 6 years old ginseng. However, it showed higher content of upland field cultivation fresh ginseng than paddy field cultivation fresh ginseng in 4 years old ginseng. Additionally, ginsenoside Rg1 showed higher content of paddy field cultivation fresh ginseng than upland field cultivation fresh ginseng in 6 years old ginseng, whereas upland field cultivation fresh ginseng showed higher content of paddy field cultivation fresh ginseng in 4 years old ginseng. The effect on the content of ginseng saponins and acidic polysaccharides according to paddy field and upland field cultivation methods is considered to be small. Conclusions: The paddy field cultivation method, which is more efficient in production cost due to depletion of farmland and long-distance cultivation, is considered to be an economical cultivation method.

A study was made to clarify the topographical. and Physical characteristics of ginseng field in terms of soil science and to find the relationship between soil characteristics and ginseng growth, as well as yield of ginseng roots Forty nine farmer's red ginseng field of ginseng growing area were chosen for this study and investigated for two years. The results obtained were as follow. 1. Ginseng fie1ds with high yield which represent the more than 1.8kg of ginseng root per 3.2m2 were found in soil series of Bancheon, Yeongog, Weongog, etc. whose texture were the clay loam to clay soil. On the other hand, ginseng field with low yield were observed in soil series of seogto whose texture was loamy soil with high content of gravels. 2 Soil of ginseng field with high yield had higher content of clay. silt soil moisture and soil pore as compared with soils of low yields. These soil characteristics were positively correlated with stem length stem diameter and root weight of ginseng plsnt and negatively correlated with rate of missing plant 3. The adequate ranges of soil 3 phase from high yield ginseng field were 40 to 50% of solid Phase, 22 to 35% of liquid phase, 25 to 35% of gaseous phase in top soil and 45 to 55% of solid phase. 28 to 30% of liquid phase. 15 to 20% of gaseous phase in subsoil respectively.

Field and laboratory works were conducted to Investigate the life history, ginseng damage and chemical control effect of the field slug, Deroceras varians A. Adams. D. varians laid eggs from April to June, but a small number of eggs were also found from July to September in the field. Most young slugs grew through the slimmer months to maturity by October. overwintered beneath the moist soil surface, and began feeding and egg-laying in the following April. indicating that D varians have a life cycle in a year. Damage of ginseng plants by D. varina occurred mainly from late April to mid May in the 3rd to 5th year ginseng fields with rice-straw mulching. It seems that this damage is caused by the adults in oviposition periods and related to rice-straw mulching of ginseng fields. In the experiment, ethoprop 5% granule and metaldehyde 6% bait showed relatively high effectiveness in the control of D. varians adults. Bordeaux mixture was more effective when the chemical was sprayed after infestation of the slug than before the infestation and when the 6-12 mixture was used.

Interrelation between environmental influences on soil microorganisms and it's effect on disease development in ginseng (Panax ginseng C.A. Meyer) field were studied to obtain a preventive measures against the root rot of ginseng caused by soil-borne pathogens in soil in three major Korean ginseng producing areas such as Kumsan, Goesan and Poonggi. Populations of actinomycetes were relatively high in fall season from September to November. Their numbers were highly populated in healthy plot in field than replanted disease field of ginseng, whereas ratio of Trichoderma spp to actinomycetes increased in healthy plot of field indicating the higher numbers of Trichoderma spp pressented in healthy plot field. The numbers of propagules of Trichoderma spp generally increased in early summer through early fall season. Their numbers were also highly populated in the healthy plot of fields. The contents of organic matter and phosphate in healthy plot of field were somewhat high, and phophate/organic matter ratio and Mg content were high in diseased replanted field. All of the soil samples showed a weak acidic pH from 4.5 to 4.7. Soilmoisture content was increased during winter season and it did not show any significant changes curing the growing period, showing 24.6% in healthy plot in field and 19.5% in deseased plot in field respectively. Soil temperature was highest in July and August and lowest in January and February.

인삼의 답전윤환재배에 있어서의 문제점을 파악하는 한편 답전윤환 재배지 토양의 이화학적 특성과 인삼의 생육 및 수량을 조사하며 논에서의 인삼연작재배의 안전성 기작을 구명하여 인삼의 답전윤환재배를 위한 기초를 확립하고자 본 실험을 수행하였던 바 그 결과를 요약하면 다음과 같다. 1. 금산지방에서의 답전윤환 인삼재배시 가장 심각한 문제점은 벼의 재배후에 토양에 잔류하는 무기염류의 과다였다. 2. 밭재배지에 비하여 답전윤환 인삼재배지에서 유기물함량과 CEC 그리고 가리를 위시한 각종 양이온의 함량이 높은 경향이었다. 3. 답전윤환 초작지와 재작지에서의 3년생 및 4년생 인삼의 경엽생육은 밭초작지 인삼의 생육과 뚜렷한 차이가 없었으나 이들에 비해 밭재작지 인삼의 경엽생육은 현저하게 떨어졌다. 또한 답전윤환 재배지에서는 황병의 발생이 많았으며 땅강아지가 우점해충이었다. 4. 답전윤환 초작지와 재작지에서의 4년생 인삼근의 생육 및 간당 근수량은 밭초작지 인삼의 생육 및 수확량과는 뚜렷한 차이가 없었으나 이들에 비해 밭재작지 인삼근의 수량은 현저한 감소를 나타내었다. 5. 답전윤환재배시 인삼의 재배후에 4년정도 벼를 재배한 다음 다시 인삼을 재배하여도 인삼에 연각장해현상이 뚜렷하게 나타나지 않았으며 또한 근부병의 발생도 심하지 않아 비교적 안전한 재작이 가능하였다. 6. 답전윤환지에서 재배된 4년생 인삼의 조-Saponin 및 개별 Saponin함량은 관행의 방법으로 재배된 인삼과 전혀 차이가 없었다. 7. 정상답에 비하여 인삼재배답 토양의 비옥도가 대체로 약간 저조한 경향이었으나 수도의 생육 및 수량에는 전혀 영향을 미치지 않았다.

국내 산양삼과 인삼 종자의 형태적 형질과 안정성 동위원소를 비교하였다. 산양삼 10개 산지와 인삼 2개 산지에서 종자를 채집하여 종자의 길이, 폭, 두께, 그램당 립수를 측정하였으며, 탄소, 질소 안정성 동위원소비를 분석하였다. 산양삼 종자의 형태적 형질과 안정성 동위원소비는 지역간에 중복되는 변이를 나타냈다. 금산지역의 산양삼과 인삼을 비교한 결과, 산양삼 종자는 인삼과 비교하여 유의하게 크기가 작고 무게가 가벼웠으며, 질소 동위원소비는 산양삼 종자에서 낮았다. 유사한 지역 환경에서 산양삼과 인삼 종자는 형태적으로 구분할 수 있었고, 산양삼 종자의 질소 동위원소비는 경작 유형을 반영하였으나, 지역간 절대적 비교는 할 수 없었다.

땅강아지에 의한 인삼의 피해가 1984~1991년에 야외 및 실내에서 조사되었다. 인삼의 땅강아지 피해는 주로 2년근(2년생) 포장에서 5~6월(춘기)에 발생하였고 성주의 야외 밀도가 높은 9~10월(추기)에는 피해가 거의 인식되지 않았다. 실내 및 강실에서, 2년근의 추기 피해는 뚜렷이 감소하였는데 인삼의 직경과는 무관하였으며, 3년근은 전혀 식해되지 않았다. 토양경도는 땅강아지 성충에 의한 인삼의 피해에 영향을 미치는 것으로 보였다.

1993~1999년에 인삼 포장 내 약제 사용을 최대한 줄일 수 있는 해충과 쥐의 방제법을 연구하였다. 인삼포장에서 참검정풍뎅이 성충을 방제하는데 있어 약제를 산란기에 포장 주변에 처리하는 것은 인삼포장 내 처리와 동일한 방제 효과를 보였다. 땅강아지 성충 피해는 약제를 포장 주변에 처리하였을 때 뚜렷이 감소하였다. 누런방아벌레 유충은 포장 내에 감자를 묻을 경우 효과적으로 유인되었다. 가루깍지벌레는 포장 내에서의 확산이 매우 늦어 발생 초기에 효과적으로 방제할 수 있을 것으로 기대된다. 쥐의 피해는 포장 내에 지진파를 발생하는 쥐퇴치기를 설치후 정지되 었다.

Growth of ginseng and physical properties of soil were compared with bed height in experimental plots of sand loam for four year and clay loam soil for three year old ginseng plants, respectively. Field survey was also carried out to compare yield and soil physical properties with bed height in the same fold of six years old ginseng fields. High yield of ginseng root was observed at high bed both in the experimental plots and field survey as well. The rate of rusty root was significantly reduced at high bed. Soil porosity increased but soil hardness decreased at high bed.

In order to clarify an effect of seedling weight on the growth pattern of ginseng, seedlings ranged from 0.4g plant to 1.8g plant were transplanted, and then the characters of 5- and 6-year-old ginseng were investigated. The characters of root and leaf, such as length and diameter of main root, root weight, leaf area, and leaf dry weight of 5- and 6-year-old ginseng originated from large seedlings were superior as compared with those from small seedlings, and percentage of missing plant was increased with the increase of seedling weight. There were, however, no significant difference in stem length, stem dry weight, number of seeds per plant and number of palmate leaves and leaflets per plant in 5- and 6-year-old ginseng and these characters were not affected by the weight of seedings transplanted. Root field per unit area was higher in seedings of above 0.6g/plant than in small seedlings.
