터널보온재 종류 및 엑셀파이프 이용 온수가온이 시설수박의 생육과 시들음증 발생에 미치는 영향 = Effect of Thermal Tunnel Covers and Warm-Water Heating Using ExcelPipe on the Growth and Wilting of Greenhouse Watermelon

국문 초록 (Abstract)

터널 보온재 종류 및 엑셀파이프 이용 온수가온이 시설 수박(Citrullus vulgaris)의 생육과 시들음증 발생에 미치는 영향을 구명하고자, 겨울철 저온기에 시설수박 주산지인 함안지역의 시들음증이 상습적으로 발생되는 포장에서 수행하였다. 3 종류의 터널 보온재(4, 8, 12온스)와 엑셀파이프를 이용 한 지표가온(터널 내 지온설정; 15℃, 20℃)의 효과를 각각 비교하였다. 터널피복용 보온재는 두꺼울수록 보온력이 좋아 건물중과 과실수량이 많고 시들음증 발생이 적었으나 8온스와 12온스 간에는 유의적 차이가 없었다. 온수가온에 의해 지온을 20℃로 설정한 것은 무가온에 비해 터널 내 기온이 3.5℃ 증가되어 생육이 촉진되고 과중이 약 800g 무거웠으며 시들음증 발생도 20％ 감소되었다. 따라서 저온기 시설수박 재배 시 야간에는 8~12온스의 보온재를 피복하고 엑셀파이프를 이용해 터널내를 가온해 줄 경우 적은 연료 소비로도 건전한 생육을 통한 생산성 향상과 시들음증 발생억제에 다소 효과적이었다.

Effects of thermal tunnel covers and warm-water heating using excel (XL) pipe on the growth, yield, and wilting of greenhouse watermelon were investigated at annually wilting field of a chief producing district, Haman. Thermal tunnel covers (four, eight and twelve ounces) and warm-water heating setpoints (15℃ and 20℃) with laying XL pipes on the soil surface during the night time were compared, respectively. High plant dry matter and fruit yield and low wilting occurrence were observed in heavier thermal cover but the difference between eight and twelve ounce was not significant. Warm-water heating of 20℃ setpoint increased 3.5℃ in air temperature and 800 g in fruit weight, and reduced 20％ in wilting occurrence, compared to those in non-heating. Results indicate that eight to twelve ounces of thermal tunnel cover and warm-water heating using XL pipe could be some effective in temperature management for high productivity and low wilting occurrence of greenhouse watermelon in low temperature season without excessive fuel consumption.
