인삼에 기생하는 해충을 억제하는 석회유황합제를 응용하되 피해를 줄이고 효과를 증진시키는 석회유황합제 복합체를 적용하고자 했다. 특히, 석회유황합제는 휴면기에만 사용하였으나 석회유황합제 복합체를 응용하여 인삼의 병해가 가장 많은 여름 장마기 전후에 사용이 가능한 것으로 나타났다. 묘삼재배에서 석회유황합제에 첨가한 복합제별 비교는 주당 무게 평균값 기준으로 했을 때 KHCO₃ > NaHCO₃ > MgSO₄ 순으로 좋은 결과를 보였다. 또한 생육상태 및 근장에서 묘삼으로 조건도 갖추고 있었다. NaHCO₃를 이용한 희석비율 효과는 석회유황합제 200배 희석액에 중탄산나트륨를 첨가한 것이 주당 무게가 가장 많이 나왔으며 체형도 좋은 것으로 나타났다. 또한, 석회유황합제 복합제 처리간격별 비교는 주당 무게 평균값 기준으로 20일 > 30일 > 40일 > 10일 순을 보였다. 5년근 인삼에 미치는 석회유황합제 복합체의 효과에 대한 현장 시험에서도 석회유황합제에 첨가한 복합제별 비교는 주당 무게 평균값 기준으로 했을 때 NaHCO₃가 좋은 결과를 보였다. 무처리구와는 큰 차이를 보였으나 처리구 상호 간에는 큰 유의차는 없었다. 처리 농도 효과도 근중으로 보았을 때 석회유황합제 200배 희석액에 중탄산나트륨를 첨가한 것이 주당 무게가 가장 많이 나왔으며 체형도 좋은 것로 나타났다. 석회유황합제복합체 5년생 인삼의 생육에 미치는 석회유황합제 복합체의 영향은 주당 무게 평균값 기준으로 20일 > 30일 > 40일 > 10일 순으로 나타났다. 따라서 묘삼과 5년근 인삼의 해충 방지에는 석회유황합제에 복합체 재료로 중탄산나트륨(KHCO₃)을 이 용하여 200배 이상 희석하여 예방용으로 장마전에 20일 간격으로 2~3회 살포하면 효과가 큰 것으로 나타났다.

This research was conducted to investigate the influence of various organic substrates on growth and yield of ginseng seedling grown organically in the closed plastic house. The pH and EC of substrates used for organically ginseng cultivation ranged 5.93~6.78 and 0.03~0.15 dS/m respectively. The concentrations $NH_4$-N and $NO_3$-N respectively was 14.01~68.63 mg/L, 5.60~58.83 mg/L. The average quantum of the closed plastic house was range from 10 to 16% of natural light. In July and August, the maximum temperature of the closed plastic house did not exceed 30 and the average temperature was maintained within 25 lower than the field because air conditioning ran. The PPV-1 and PPV-2 bed soil substrates produced higher stem length, stem diameter, shoot fresh weight and leaf area than those of conventional culture. In PPV-2 bed soil substrates, root fresh weight and root diameter was the highest. The root fresh weight of PPV-2 bed soil substrates in closed plastic house was maximum 25% heavier than the conventional cultivation. The results of this experiment will be utilized for making new substrate application for organic ginseng culture in the plastic house.

Purpose: Using agricultural machinery was not easy in the conventional shading structure, specified as a standard facility by standard cultivation methods for ginseng. Thus, this study designed the new types of facility allowing machine access by modifying the conventional type. Methods: Two types of facility (i.e. wide roof type and long & short roof type) were designed and installed in an experimental site to evaluate its growing environments and applicability of riding-type cultivator. Results: From the results of incoming light measurement, all three types (i.e. two new types and a conventional type) of shading structures blocked the incoming light after 9:00 am. The temperature distribution inside the new types was similar with the one in the conventional type, so the growth of ginseng was in good condition in all three types of facility. The riding-type cultivator was operated well with the low speed first gear of 0.13 m/s in the new types. However, a long & short typed roof needs to be raised 18 cm height in order to use the cultivator. Conclusions: With the results of this study, the new types of roof can be used in the ginseng farm in that they satisfied the growing environments for ginseng and the needs for agricultural mechanization.

It is well-known that cultivated wild Panax ginseng has anti-inflammatory effect. However, a comparative study on cultivation period vs biofunctionality is currently lacking. In this study, 70% ethanol extracts of 3-years (yrs)-, 5-yrs-, or 7-yrs-old cultivated wild ginseng were evaluated for their inhibitory effects on RAW264.7 murine macrophages. Specifically, the production of pro-inflammatory cytokines (interleukin-6 [IL-6] and tumor necrosis factor-alpha [TNF-${\alpha}$]), the expression of surface proteins (CD80, CD86, and MHC-II), and the phagocytic properties were investigated. RAW264.7 cells were induced by 500 ng/mL of lipopolysaccharide (LPS) and treated with 0.1, 1, and 10 ppm of samples. LPS-induced IL-6, TNF-${\alpha}$ and surface proteins in all samples were down-regulated in a dose-dependent manner. Both IL-6 and TNF-${\alpha}$ were significantly reduced at 10 ppm of the 7-yrs-old sample compared to 10 ppm of 3-yrs- and 5-yrs-old samples. CD80 and CD86 were also reduced at 10 ppm of all samples, and there was no difference among samples. The phagocytosis has no difference except in 10 ppm of 3 yr-old sample. The results suggest that cultivated wild ginseng extract has anti-inflammatory effect without decreasing phagocytosis.

This study was performed to investigate the effects of sowing density and number of seeds sown on the emergence rate and growth characters of Panax ginseng C. A. Meyer under direct sowing cultivation in a blue plastic greenhouse. Ginseng seedlings, derived from seeds sown directly at different densities (90, 108, 135, and 162 seeds per $162m^2$), were cultivated in sandy loam soil within a blue plastic greenhouse. In contrast to the emergence rate, which decreased with an increase of sowing density, number of survival plant showed an increasing trend. Interestingly, the emergence and number of survival plant were significantly enhanced when 2 or 3 seeds were sown per hole compared with when one seed was sown per hole. Growth of the aerial parts of ginseng were not markedly influenced by sowing density or the number of seeds sown. However, chlorophyll content (SPAD values) increased with an increase in sowing density. Root parameters, such as root length, diameter, and weight, and the number of lateral roots decreased with an increase in sowing density, but were not noticeably influenced by the number of seeds sown. Total saponin content was the highest in the treatment plot containing 135 seeds. Similarly, the content of each ginsenoside was also tended to be higher in this treatment than in other treatment plots. On the basis of the results obtained in this study, it was possible to determine the optimal sowing density and seed number for the direct sowing cultivation of ginseng in blue plastic greenhouse.

Background: Panax ginseng Meyer has widely been used as a traditional herbal medicine because of its diverse health benefits. Amounts of ginseng compounds, mainly ginsenosides, vary according to seasons, varieties, geographical regions, and age of ginseng plants. However, no study has comprehensively determined perturbations of various metabolites in ginseng plants including roots and leaves as they grow. Methods: Nuclear magnetic resonance ($^1H$ NMR)-based metabolomics was applied to better understand the metabolic physiology of ginseng plants and their association with climate through global profiling of ginseng metabolites in roots and leaves during whole growing periods. Results: The results revealed that all metabolites including carbohydrates, amino acids, organic acids, and ginsenosides in ginseng roots and leaves were clearly dependent on growing seasons from March to October. In particular, ginsenosides, arginine, sterols, fatty acids, and uracil diphosphate glucose-sugars were markedly synthesized from March until May, together with accelerated sucrose catabolism, possibly associated with climatic changes such as sun exposure time and rainfall. Conclusion: This study highlights the intrinsic metabolic characteristics of ginseng plants and their associations with climate changes during their growth. It provides important information not only for better understanding of the metabolic phenotype of ginseng but also for quality improvement of ginseng through modification of cultivation.

Objective: The aim of this study was to find risk factors in cultivating ginseng based on risk assessments and suggest safety measures for main risks. Background: Safety education and training is one of the practical and effective methods to prevent occupational accidents and injuries. In agricultural sector, there are few contents of safety education as compared to other industries. Especially, farm work has different cultivation characteristics according to the crops, so it needs special education materials for each crop. Among the various types of crops, ginseng contains various risk factors due to its long cultivating period and unique environment. Therefore, safety education material specified for ginseng is necessary to improve ginseng farmers' safety. Method: Risk assessment for cultivating tasks of ginseng was carried out through data obtained from various methods (site survey, interview, literature survey). To improve objectivity, the risk assessment was applied with 3-criteria (researcher estimate, interview, previous research results). Finally, the three high-risk tasks were selected and safety measures for those tasks were provided. Results: Three tasks, such as 'Mounting, maintenance and removing supports', 'Pest control' and 'Harvest', were selected as risky tasks among total tasks. (1) In 'Mounting' and maintenance and removing supports', the farmers found to be exposed to the risks of musculoskeletal disorders and accidents related to operating the tablet machine. (2) In 'Pest control', agrichemical poisoning, musculoskeletal disorders and hyperthermia were main risks. Finally, (3) In 'Harvest', the farmers are mainly exposed to the possibility of accidents of agricultural machines and risks of musculoskeletal disorders. Thus, it needs to apply appropriate safety measures to those risky tasks, such as safety guidelines, convenience equipment, protective kit, and so on. Conclusion: This study can be used as basic data for agricultural safety and expected that it would be useful for further study. In addition, the results of the research will be produced in the form of animation, which will enhance the safety consciousness for aged farmers. Application: The result of this study can be used in developing safety education materials for ginseng farmers which is essential to prevent occupational accidents and injuries among ginseng farmers.
