초록

The areas of vinyl greenhouse have steadily grown in Korea. Climate condition is far from optimal inside vinyl greenhouses because of the limited ventilation and lack of cooling and heating. Carbon dioxide was more than 50% higher than pre-industrial levels. Agricultural activities are estimated to account for about 13.5% of the total greenhouse gas. The objective of this study was to predict the CO2 concentration and temperature in the inside and outside of vinyl greenhouse applied compost and liquid fertilizer. In this study, we compared the CO2 concentration and temperatures inside and outside greenhouses. The investigation was performed in 54 vinyl greenhouses located in Yeoju and Boryeong regions, Korea. The CO2 concentration inside and outside of vinyl greenhouse were measured in the period from 2021 to 2022. The mean CO2 concentration inside a greenhouse in the Yeoju and Boryeong was 499.6 and 516.2 ppm, respectively. Inside the greenhouse, the highest mean CO2 concentration had values of 600.8 ppm, and the minimum level of CO2 was 477 ppm in Boyeong. The seasonal CO2 concentration was observed in March and April with a maximum occurrence and in July-August with a minimum occurrence. The average CO2 concentration of inside the vinyl greenhouse is 10.1 ppm higher than that of outside atmospheric CO2 concentration.
During summer season, inside temperatures was high as 31.9~33.7°C. The difference between the inside and outside temperatures of vinyl house was around 1~3°C. Therefore monitoring of CO2 concentration and temperature of vinyl greenhouse is needed.
