'막덮기 피복재'가 결구상치의 생육, 수량 및 품질에 미치는 영향 = Effect of Row Cover on the Growth and Development, Yield, Quuality in the Lettuce

국문 초록 (Abstract)

동계에 있어서 무가온시설내의 결구상치 재배의 저온환경을 개선하기 위하여 1987년 10월 ∼ 1988년 2월에 걸쳐서 결구상치의 공시품종을 '돗푸마-그'로 하였고, 피복자재는 할섬유부직포인 다후베루와 장섬유 부직포인 마리에스, 파스라이도, 파오파오 90으로 하여 무처리와 비교 검토하였다.
주간의 기온은 무처리구에 비하여 각 처리 모두 낮았으나 저온은 높았다. 야간의 기온은 주간과 반대로 높았고, 지온도 높았다. 주야간의 온도비교에서 기온은 격차가 컸으나(특히 무처리구와 파오파오 90구) 저온은 격차가 적었다.
생육(초장, 엽수, 엽면적, 결구율) 및 수량(생체중)은 무처리에 비하여 각 처리구 모두 양호하였고 그중 파오파오 90이 가장 생육촉진과 증수효과가 높았으나 건물율, 엽록소 함량은 각 처리구 모두 낮았고 염색도 엷었다.

This study was executed to improve the environment on low temperature of the lettuce unheated plastic house in the winter season. The trial cultivar was used with 'Dotpumaag' and the trials was used with Tahuberu, Maries, Paslido, Paopao 90 during October 1987 to February 1988.
Day temperature was lower in all row cover treatment than control but it was higher at soil temperature. Night temperature was higher in all row cover treatment than control and at soil temperature, too. Air temperature was appeared large difference between day temperature and night temperature but it was small at soil temperature.
The growth and development and yield was excellent in all row cover treatment than control and the most materials that growth and development was promoted and yield was increased in all treatment was Paopao 90 but percentage of dry matter and content of chlorophyll was lower in all row cover treatment than control.
