본 연구는 저온기 시설참외 재배 시 탄산가스 발생제(탄산솔)의 사용효과를 구명하기 위하여 수행하였다. 600 m2 크기 하우스에 탄산가스 발생제(100g/1봉)를 10, 20 및 30봉을 각각 매달아 무처리와 비교하였다. 그 결과 무처리구에 비해 처리구에서 탄산가스 농도가 3.0~3.2배 정도 높았다. 그리고 무처리구에 비해 처리구에서 과중이 20.2~22.0g 더 무겁고, 태좌부 당도가 1.5~2.1oBrix 더 높았으며, 색도(a값)도 우수하였다. 또한 탄산가스 발생제 처리한 것이 무처리에 비해 발효과율 및 기형과율이 각각 2.9~3.9%, 5.4~7.3% 감소하였고, 상품과율은 8.7~10.3% 증가하였다. 10a당 상품과 수량은 무처리구의 385.8kg에 비하여 탄산가스 발생제 10, 20 및 30봉 처리 한 것이 각각 10.3%, 14.8%, 16.2% 증가하였다. 이상의 결과를 보아, 저온기 참외 시설재배시 탄산가스 발생제를 시용함으로써 탄산가스 농도가 높아져 광합성이 촉진되어 품질이 향상되고 수량이 증가한 것으로 판단되었다.

The objective of this study was to examine the changes in carbon dioxide (CO2) concentration due to application of solid CO2 generator (Tansansol) in plastic greenhouses during winter cultivation of Korean melon. The experimental treatments consisted of four levels, namely, 0 (control) 10, 20 and 30bags with solid CO2 generator per 600 m2 of plastic greenhouse. CO2 concentration in plots with solid gas generators was higher by 3.0-3.2% compared to control. Fruit weight, sugar content and color parameter were also enhanced due to application of solid CO2 generator. The fraction of fermentated and unmarketable fruits were decreased by 2.9-3.9% and 5.4-7.3%, respectively, in plots where solid CO2 generators were applied. The marketable yield increased by 10.3, 14.8 and 16.2% in plots with 10, 20 and 30bags with CO2 generators, respectively. As a result, CO2 concentration within the greenhouses was increased by applying CO2 generators and it is positively affected the rate of photosynthesis.
