Background : The production of healthy ginseng seedling is a critical part of growing 5-6-year-old fresh ginseng. Recently, for the problem of replant failure, it becomes more and more difficult to find first planted field for ginseng seedling cultivation. In this situation, This study was conducted to examine the possibility of seedling production practices of ginseng by utilizing the multi-beds cultivation system as a way to produce ginseng seedling stably. Methods and Results : This experiment was conducted by installing a 3-layed cultivation beds using 50㎜ sandwich panels. As the 1st and 2nd beds get insufficient amount of light, fluorescent lights were installed in 2 rows to further lighten up. And the 3rd bed used natural light. The bed soil used was formulated by mixing saprolite, yakto and peat moss. The control was cultivated under natural light on 1-layed bed with commercial bed soil for ginseng seedling. The commercial bed soil had pH 7.24, higher than the standard of permission, 6.5; and its calcium and sodium contents were 10.7, and 0.85 cmol+/㎏, respectively, higher than the standard. The available phosphate concentration was 34.0㎎/㎏, lower than the appropriate level of 100 ㎎/㎏. The mixing bed soil also had pH 7.69, higher than the standard but its nitrate and phosphate were within the appropriate range. The intra-facility light quantities of the 1st and 2nd beds were constant at around 100 μmol during days. But the light quantity of the 3rd bed was 51.4 μmol in average daily value. The roots of the 1st-3rd beds were found to weigh 0.58 – 0.73 g while those of the control group, about 0.47g to show heavier root weight of the multi-beds cultivation ginseng than that of the control. As for the yield, the control showed 145 ㎏/10a whereas the 1st-3rd beds showed higher levels between 183 – 228 ㎏/10a. Conclusion : In the multi-beds cultivation of ginseng seedling, fluorescent lamps seem to have provided sufficient light as an artificial light source. The soil for ginseng seedling production is different from ginseng cultivation field soil, additional study will be also necessary to set up the physiochemical range of bed soil for ginseng seedling.
