Background : Recently, some ginseng has been greenhouse production within the purse of fresh vegetables. The chemical of bed soil is very important because this leads to the stabilization of production in ginseng cultivation. The objective was to investigate the effects of composition of bed soil type on the growth. Methods and Results : Bed soil was commercial bed soil to the control and compared bed soil in 5 types. Culture nutrient solution was modified from Korea Wonshi nutrient solutions. Nutrient solution supply system has been applied to sub-irrigation system. Light intensity and photoperiod were 100 μmol⋅m-2⋅s-1 and 16 h, respectively; and air temperature was maintained at 25 ± 5℃. Nutrient solution was supplied after transplantation 20 days. Soil sampling was investigated every 30 days, and shoot growth were investigated from 60 to 150 days. Bed soil analysis result, the content of NO3 and P2O5 were significantly changed after 60 days in all types soil. The quantity of NO3 and P2O5 decreased with increase growth period. Also, Growth of roots showed a large influence of the soil pH. Conclusion : Results for ginseng hydroponic culture will enable the production of stable soil environment and efficient ginseng fresh vegetables.
