Abstract

This study was carried out to investigate the proper wattage and installation distance for the efficient use of nano-carbon fiber infrared heating lamp (NCFIHL), a heating device advantageous for heating energy saving, when the production of watermelon plug seedlings in the plug seedling nursery in winter season. Six small beds were divided into plastic film, and 700 W and 900 W nano-carbon fiber infrared heating lamps were installed at 100 cm above the bed. 1 lamp at central (control), 60 cm interval (2 lamps), and 40 cm interval (3 lamps) heating lamps were installed in each bed inside the greenhouse. All treatments, except the control, were set to keep the night air temperature at 20℃ after lighting the NCFIHL. The leaf temperature showed a tendency to increase fast as the install distance was narrow. The leaf length and leaf width tended to increase as the installation distance of the 700 W heating lamp was narrow. The compactness was high in 700 W heating lamp with 40 cm of installation distance. Therefore, in consideration of maintaining the set temperature at night, installing 700 W electric lamps at 40 cm was an efficient power and installation distance for watermelon grafted seedlings considering economic feasibility.

본 연구는 동절기 공정육묘장의 수박 플러그 묘 생산 시, 난방 에너지 절감에 유리한 난방장치인 나노탄소섬유 적외선 난방등의 효율적인 사용을 위한 적정 전력과 설치 간격을 구명하기 위해 수행되었다. 유리온실 내 소형 베드 6개를 플라스틱 필름으로 구획을 나누었으며, 100cm 높이에 700W와 900W 난방등을 설치하였다. 난방등은 설치 간격을 각각 중앙 1개(Control), 60cm 간격(2개), 40cm 간격(3개)으로 설치하였다. 나노탄소섬유 적외선 난방등을 점등한 후 대조구를 제외한 모든 처리에서 설정한 야간 기온(20℃)을 유지하였다. 엽온은 난방등 설치 간격이 좁을수록 빨리 상승하는 경향을 보였다. 나노탄소섬유 적외선 난방등을 사용함에 따른 처리구간 수박 접목묘의 생육에는 뚜렷한 차이가 없었으나, 엽장과 엽폭은 700W 난방등에서 설치 간격이 짧을수록 길어지는 경향을 보였으며, 700W 난방등을 40cm 간격으로 설치하였을 때 묘의 충실도가 높은 값을 나타내는 것을 확인할 수 있었다. 따라서 야간 기온 유지와 묘의 충실도를 고려하였을 때, 700W 난방등을 40cm 간격으로 설치하는 것이 수박 접목묘를 생산하는데 경제성을 고려하여 효율적인 나노탄소섬유 적외선 난방등의 전력과 설치 간격으로 판단된다.
