초록

본 연구에서는 알루미늄 증착필름을 온실 내부의 터널 피복자재와 측면 자재로 활용하여 기존 난방법의 보온 효과를 극대화할 수 있는 방법을 구명하였다. 알루미늄 증착필름 활용시 기존 폴리에틸렌 필름보다 보온 효과가 높고, 작물의 생육속도도 빨라졌음을 확인하였다. 알루미늄 증착필름이 작물에서 방출되는 복사열을 반사해 온실 내부 기온 및 작물 품온 유지에 영향을 주었으며, 이로 인해 적산온도가 상승하여 작물의 생육이 빨라진 것으로 판단된다. 본 연구 결과, 알루미늄 증착필름을 방울토마토 저온기 재배 단동형 온실 보온자재로 사용 시 기존 난방법의 보온 효과를 극대화할 수 있었으며, 이에따라 가온 에너지 절감 효과도 기대된다. 또한 적산온도 증가에 따른 작물 생육 속도 증가로 재배자의 목적에 따라 재배 시기를 조절할 수 있을 것으로도 사료된다.

영어초록

Tomatoes are a seasonal crop that require insulation due to being cultivated from December to February, when the average daily temperature remains around －2°C. The primary techniques employed for insulation in single-span greenhouses include tunnel cultivation, heating equipment, and multi-layer insulation curtains.
Nevertheless, the rise in operational expenses, such as fuel and materials, has placed considerable pressure on farmers.
Consequently, there is a necessity to choose cost-effective and readily installable insulation materials. The purpose of this study was to confirm the insulating properties of aluminum-metalized film when used as a covering material for tunnels and as a side material for cultivating low-temperature cherry tomatoes. The testing results demonstrated that the average nighttime temperature within the tunnel was 2.8°C higher while employing aluminum-metalized film as the tunnel covering material compared to using polyethylene film. Furthermore, upon the tunnel's opening after sunrise, the polyethylene film tunnel exhibited 100% guttation, whereas the aluminum-metalized film tunnel showed just 21% guttation. When employing aluminum-metalized film as a side material for a heated single-span greenhouse, the daily temperature increase was 1.2°C more compared to utilizing polyethylene film on the side. Additionally, the rate of flower bud formation was accelerated by up to 0.75 buds. It was confirmed that the use of aluminum-metalized film as an insulation material resulted in excellent insulation and crop growth. Additionally, the insulation improvement impact of employing aluminum-metalized film allowed for an earlier harvest time.
