Abstract

This experiment was carried out to investigate the effect of ridge direction (south-north) on temperature and light intensity on early growth of oriental melon under east-west oriented vinyl house cultivation. The air-temperature of minimum between north and south-ridge in the tunnel of vinyl house was $12.5^[\circ}C\;and\;11.3^{\circ}C$ and that of maximum between north and south-ridge was $36.7^{\circ}C\;and\;34.7^{\circ}C$, respectively. The minimum and maximum air-temperature of north-ridge in the tunnel of vinyl house on Feb. 15 were $12^{\circ}C\;and\;2.0^{\circ}C$ higher than those of south-ridge, respectively. The intensity of daylight between south and north-ridge was similar during 9:00-10:30 a.m., that of south-ridge was higher than north-ridge during 10:30-11:30 a.m. and that of north-ridge was higher than south-ridge during 11:30-17:30. The plant growth after 55 days of planting on the north-ridge was prominent cultivation compared to south-ridge. The female flowering and first harvesting day were earlier in north-ridge than in south ridge. The marketable fruits rate and yields (kg/10a) were $6.7\%$ and 218kg higher in north-ridge cultivation than south-ridge, respectively. Differences of marketable fruit rate and yield (kg/10a) in each ridge were significant.

참외 시설하우스는 거의 대부분 단동형이며 논의 형태에 따라 동$\cdot$서동, 남$\cdot$북동으로 설치되어 있다. 동$\cdot$서동의 경우 남쪽이랑과 북쪽이랑을 만들어 참외를 재배하는데 이랑위치에 따라서 초기생육 차이가 크다. 본 시험은 동$\cdot$서동 하우스내 이랑위치별 온도, 조도 및 초기생육을 구명하기 위하여 금싸라기은천참외에 신토좌 접목묘를 1월 18일 정식하여 12온스 보온부직포를 이용하여 무가온 재배하였다. 2월 15일 터널내 최저온도는 남쪽이랑은 $11.3^{\circ}C$, 북쪽이랑은 $12.5^{\circ}C$, 최고온도는 남쪽이랑은 $34.7^{\circ}C$, 북쪽이랑은 $36.7^{\circ}C$로 남쪽이랑에 비하여 북쪽이랑에서 최저온도는 $1.2^{\circ}C$높았고 최고온도도 $2.0^{\circ}C$높았다. 일사량은 9시부터 10시 30분까지는 남쪽이랑과 북쪽이랑이 비슷하였으나 10시 30분부터 11시 30분까지는 남쪽이랑에서 일사량이 많았고 1띠 30분부터 17시 30분까지는 북쪽이랑에서 일사량이 많았다. 정식 55일 후까지의 생육은 남쪽이랑에 비하여 북쪽이랑에서 초장, 경경, 엽수 등 생육이 월등히 우수하였다 암꽃 개화 및 첫 수확일수도 남쪽이랑에 비하여 북쪽이랑에서 빨랐으며 남쪽이랑에 비해 북쪽이랑에서 상품율은 $6.7\%$ 10a당 수량은 218kg 더 많았다.
