Cultivation environment under rain shelter and growth characteristics of 5-year old ginseng

This study is designed to develop the high temperature reduction technology in ginseng’s facility cultivation responding to climate change. Accordingly, the research was focused on the effect of the covering materials of ginseng’s facility house and the high-temperature reduction treatment on the growth of 5-year old ginseng. For the blocking of light, the scattering film, blue-white double-sided film, and PE film were installed while for the reduction of high temperature, aluminum screen 40%, isoprene and non-treatment were used. The aluminum screen 40% installed inside the facility had the lowest high temperature compared to other methods during the period of hot temperature. The photosynthesis speed in the scattering film + aluminum screen 40% showed the highest. As for the high temperature’s damage to the ginseng, it was the lowest in case of aluminum screen 40%, followed by the isoprene and non-treatment. As for the growth of the underground part of ginseng, the weight of root of ginseng cultivated under the scattering film + aluminum screen 40% and isoprene was the highest. In conclusion, it was found that when the ginseng is cultivated in the facility house during the period of high temperature, the scattering film + aluminum screen 40% showed reduced damages to the ginseng but enhances the quantity of ginseng.
