초록

It is very important factors to control optimal light transmission ratio and soil moisture content in order to
produce good quality of ginseng seedling. To study the effect of light transmission ratio (LTR) and soil moisture content
(SMC) on growth characteristics and yield of ginseng seedling, LTR was controlled by three level such as 21.2, 24.8% and
30.3%, and SMC was plotted by four level of 11.0%, 12.5%, 15.3% and 18.9% at the greenhouse. Chlorophyll content was
gradually decreased in the low LTR (21.2%), while it was distinctly decreased by the decrease of SMC in excessively high
LTR (30.3%). The decrease of SMC in the high LTR increased heat injury ratio distinctly, while heat injury ratio in the low
LTR was only increased when SMC was very low such as 11.0%. All of fresh root weight per Kan (3.3㎡), root weight per
plant, and the number of usable seedling were distinctly decreased by the increase of LTR and the decrease of SMC. Excessive
increase of LTR in optimal SMC (18.9%) hadn't a great effect on the decrease of root weight, while root weight in low
SMC was distinctly decreased by the increase of LTR. Ratio of rusty root was distinctly increased in the condition that both
of LTR and SMC were high. Ratio of rusty root in the excessively high LTR was gradually fallen off by decrease of SMC, but
its ratio in low SMC didn't changed distinctly by the decrease of SMC.
