Abstract

In order to evaluate the modified installation methods of roof ventilation devices, derived from the previous experiment ('investigation into the optimum capacity of roof ventilation devices and their deployment'), the conventional and modified (improved) roof ventilation systems were installed in the single-span plastic greenhouse for growing oriental melons. The roof vents (60ϕ) and roof fans (maximum air capacity of 38m3/min) were installed in the spacing of 15m (FT, modified ‘side vent+roof fan’ ventilation) and 6m (TT, modified ‘side vent+roof vent’ ventilation) respectively on the roof of greenhouses for the modified roof ventilation treatments, and 20m (FC, conventional ‘side vent+roof fan’ ventilation) and 8m (TC, conventional ‘side vent+roof vent’ ventilation) for the conventional ones. The stem diameter, leaf blade lengh, petiole length, and leaf width were lower in the FT and TT treatments than those in the conventional treatments, FC and TC. Although the fruit weight and total yields were slightly lower in the FT and TT treatments, the marketable fruit ratio (%) were higher, as a result of increased fruiting ratio (%) in these treatments, than those of FC and TC. The marketable yields (kg/10a) in the FT and TT treatments were 8,391 kg/10a and 7,283 kg/10a, which were respectively 661 kg/10a and 487 kg/10a higher than those in the treatments of FC and TC. The modified installation methods of roof fan resulted in production of more female flowers and lower fruit drop ratio (%) compared to conventional meathods. In the treatment of the conventional ventilation with roof vent, the fruit weight, fruit length & width, and flesh thickness were higher than in other treatments, but there were no significant differences in the fruit width and flesh thickness among the treatments.

지붕 환기장치 설치방법의 개선에 의한 작물 재배효과 를 검증하고자 농가현장에서 개선 지붕 환기방식과 관행 환기방식을 비교, 분석하였다. 개선 지붕 환기방식은 참 외재배 단동 플라스틱 온실(폭 5.6m, 길이 108m, 측고 1.1m, 동고 2.2m)에 지붕 환기팬(용량 38m3/min)과 환기 통(지름 60cm)을 각각 15m와 6m 간격으로 설치하였고, 대조구로서 관행 지붕 환기방식은 각각 20m와 8m 간격 으로 설치하였다. 관행 및 개선 지붕 환기 방식에 따른 생육을 조사한 결과, 관행 환기통과 환기팬 처리에 비해 개선 환기통과 개선 환기팬 처리에서 경경, 엽장, 엽병 장, 및 엽폭의 값이 낮게 나타나는 경향을 보였다. 생육 기 전반부에 관행 환기통 처리는 환기팬 처리에 비해 절 간장이 다소 길게 발달하였는데 이는 착과수가 환기팬 처리에 비해 적었고, 착과수 감소로 인해 동화산물이 잎 과 줄기의 신장부로 좀 더 이동된 영향으로 판단되었다. 참외재배 단동 비닐하우스에서 과실 수량을 조사한 결과, 개선 환기팬과 개선 환기통 처리는 관행처리에 비해 과 중은 약간 작았지만, 착과수 증가로 인해 전체 수량은 높게 나타났다. 개선 환기팬과 개선 환기통 설치 하우스 에서는 관행 지붕 환기 하우스에 비해 상품과율이 높았 으며, 10a당 상품수량도 각각 8,391kg, 7,283kg 으로 나 타나 관행 지붕 환기에 비해 개선 환기팬 처리는 661kg, 개선 환기통 처리는 487kg 더 증가하였다. 개선 환기팬 처리는 고온기에 암꽃수와 착과수가 가장 많았고, 낙과수는 가장 낮게 나타났으며, 관행의 환기통 처리에 비해 과실의 크기는 작았다. 시기별 환기방식에 따른 참 외 과실의 품질을 조사한 결과, 관행 환기통 환기에서 과중, 과경, 과폭, 및 과육두께가 가장 높게 나타났으나, 과폭, 과육두께에 있어서 통계적인 유의차는 나타나지 않았다.
