Background : Cnidium officinale M. is a medicinal plant used a lot of herbal and functional food ingredients. Recently, the area of cultivation has been increased due to the increase in domestic demand. By the way, this plant is very vulnerable to high temperature, and recently it is difficult to cultivate due to abnormal high temperature and so on. Therefore, in this study, in order to effectively reduce the high temperature of the field, we investigated the degree of temperature reduction and the growth condition of the plant after installed mulching, irrigation and the fog facilities. Methods and Results : In order to reduce the temperature of C. officinale M. cultivation field, the black and white double vinyl mulching, drip irrigation and fog spray treatment were applied and the results were as follows. The survey was conducted at about 2:00 pm on a clear day in August, and the temperature was about 33℃ at the time of measurement. In the case of only black vinyl mulching without watering, the soil temperature was 43.5℃, the surface temperature was 61.4℃, and the mortality rate of the C. officinale M. was 98.0%. The temperature of soil and surface were lowered to 33.1℃ and 38.6℃, respectively, when treated with black vinyl mulching and drip irrigation and fog spraying. In the case of black and white double vinyl mulching, the effect of temperature reduction was better. The soil surface temperature of the non-irrigation treatment was 37.9℃, the surface temperature was 48.5℃ and the mortality rate was decreased to 6.7%. In case of combined drip irrigation and fog spraying, soil temperature was reduced to 31.5℃, surface temperature was 35.8℃, and mortality rate was 0%. Conclusion : As a result of this study, the temperature of soil and surface dropped by up to 12. 0℃ and 25.6℃, respectively, when combined with black and white double vinyl mulching and drip irrigation and fog spray treatment. The mortality rate declined from 89.0% to 0%. Therefore, Therefore, if the results of this study are applied to the cultivation of C. officinale M., it is expected that the production stability will be improved.
