Effect of Shading Treatments on Cultivation Environments and Growth of Korean Ginseng (Panax Ginseng C. A. Meyer) under Rain-Shielding Conditions

초록

Background : This study was carried out to secure technology for stable production of ginseng by developing technology to reduce the high temperature in response to climate change.
Methods and Results : Polyethylene film (PE film), scattering film and blue-white double-sided film (85% shading rate) were tested for ginseng rain-shielding materials. The shading materials used were a black shading net (90% shading rate) in the first, and an aluminum screen (40% shading rate) in the second. The first shading materials were installed on April 10 with PE film + black light shielding net, and scattering film + black light shielding net. As the treatment for high temperature injury relief, an aluminum screen was installed under a scattering film + black light shielding net and a blue-white double-sided film at a high temperature. The amount of transmitted light was 12.9% at scattered film, 14.5% at double sided film, and 12.5% at PE film when the primary rain-shielding material was covered. In secondary shading, scattering film + aluminum screen and blue-white double-sided film + aluminum showed 8.6% and 7.6% of light transmitting, respectively. In the case of temperature, the average temperature was lower than the outside temperature at the scattering film + aluminum screen, clear double sided film + aluminum screen and PE film recovery. The differences among the cultivars were significant in plant height, stem height, stem diameter, leaf length, leaf width and leaf area. There were significant differences in the plant height, stem height, leaf length, and leaf width between treatments, but there was no interaction effect between varieties and treatments. The interactions between treatments were found only in the number of brach root.
Conclusion : High temperature damage was influenced by the amount of irradiation in the facility rather than the temperature, which was presumed to be due to the accelerated aging of the ginseng leaf as the light transmittance increased.
