  • To get the basic information about ginseng seedling production, yields of ginseng seedling and soil physico-chemical components in 32 fields of Yang-Jik and 19 fields of Ban-Yang-Jik nursery were investigated. Germination rate is $78.5{\pm}3.0%$, $77.8{\pm}2.8%$ in Yang-Jik and Ban-Yang-Jik. Rate of number of mature seedlings to number of seeds planted is $62{\pm}13.5%$, $53{\pm}12.6%$ in Yang-Jik and Ban-Yang-Jik. Rate of number of available seedlings to number of seeds planted (Rate of available seedling) is $42{\pm}12.5%$, $26{\pm}12.1%$ in Yang-Jik and Ban-Yang-Jik. The number of available seedlings per Kan (Kan means $180{\times}90cm$ area) is $627{\pm}187$, $368{\pm}182$ in Yang-Jik and Ban-Yang-Jik. Rate of number of unusable seedlings to number of mature seedlings is 34%, 51% in Yang-Jik and Ban-Yang-Jik. It showed the negative correlation between amount of coarse sand and stem height, and central leaf length, on the other hand, possitive correlation between amount of extremely fine sand, and stem height, and central leaf length respectively. Rate of available seedling was positively correlated with amount of medium, fine and extremely fine sand, whereas negatively correlated with amount of coarse sand in Yang-Jik. Root weight per seedling was positively correlated with amount of medium, fine and extremely fine sand. Contents of organic matter, available phosphate and potassium in Ban-Yang-Jik were higher than those of Yang-Jik, but content of lime was higher in Yang-Jik compared to that of Ban-Yang-Jik. Possitive correlations were showed between leaf area per seedling and content of organic matter, and between stem height and content of lime in Yang-Jik. Root weight per seedling was positively correlated with content of organic matter and magnesium in Ban-Yang-Jik, but there is no correlation between any of soil chemical components and root weight in Yang-Jik.

  • This study was conducted to elucidate the effect of physical properties of soil in nursery bed with different densities on growth of ginseng seedling. Stem length, leaf length and leaf width of ginseng seedling showed the decreasing tendency with increasing the hardness of the nursery soil. Fresh root weight per seedling and number of available seedlings were increased significantly with decrease of the soil hardness. For solid, liquid phases, bulk density and hardness of soil, negative correlations were shown in stem length, leaf length, leaf width, root weight per seeding, and number t of available seedlings. On the other hand, gas phase, air permeability and porosity of soil had positive correlations with stem length, leaf length, leaf width, root weight per seedling and number of available seedlings. Key words Yang-Jik nursery, ginseng seedling, soil physical properties.
