Background : This experiment was carried out to improve the labor-intensive task to construct of the traditional ginseng shading system in Korea. In this experiment the selected shading materials was new 6 kinds that HDPE - knitted- monofilament and taped PE Net, with taking into account of the amount of light and the amount of leakage to screen the UV stabilized 0.3% - 0.6%. Compared with the traditional shading material, the black-shading material (wt. 200g/㎡) and the yellow shading material (wt. 300g/㎡) was suitable for the ginseng growing environments in Korea. Methods and Results : The installation of shading system was the 45 degree slope -2 meter height from the ground with the selected shading materials for the wide structure ginseng cultivation. Temperature and light intensity was measured with a week interval from the surface to a height of 30cm. The two kinds of the 1st selected materials and the traditional black + blue two layer shading materials, aluminum screen, Canada Gintec shading material, total 5 kinds of materials were installed in wide structure. The growing environmental analysis was measured using data logs (watchdog 1600series). Conclusion : In the first selection of shading materials for Ginseng wide structure, the levels of light intensity were higher in order of blue-shading> Aluminum- shading> black-shading order. The temperatures of the under wide structures were lower in order of the black-shading< aluminum-shading screen< blue-shading order, especially the temperature of the black shading material was lower than the outside temperature. For the second selection of shading material of the ginseng wide structure, the black and yellow shading material were superior to the other materials, in the amount of light shading material and growing conditions and the degree of leakage etc. The temperatures of mid-May in wide structures of ginseng cultivation were higher in order of aluminum-screen> Canada shading materials (Gintec Co.) 2 layer material> Yellow shading> black shading order, and also the amounts of light intensity also was shown to be with the same manner
