고온기 반밀폐형온실 냉방이 파프리카 생육과 광합성 특성에 미치는 영향 Effect of Cooling in a Semi-closed Greenhouse at High Temperature on the Growth and Photosynthesis Characteristics in Paprika원문보기
본 연구는 냉방이 가능한 반밀폐형온실과 일반 플라스틱온실에서의 정식 후 고온 스트레스가 파프리카에 미치는 영향 구명을 위해 수행하였다. 지열과 팬앤패드를 활용하여 냉방이 가능한 반밀폐형온실의 파프리카는 냉방이 되지 않는 3중 플라스틱 하우스의 파프리카보다 유의적으로 높은 광합성 속도를 보여 주었다. 플라스틱 하우스의 파프리카가 고온 스트레스에 의해 광합성 속도가 느려지는 것을 제시하고 있다. 초장은 반밀폐형온실이 13cm 더 높게 증가하였으며, 엽면적은 이식 후 2주차까지 생장 속도가 비슷하였으나 3주차 경과 시 반밀폐형온실이 플라스틱온실보다 47% 높은 차이를 보였다. 착과 수는 반밀폐형온실 10.6개/주, 플라스틱온실 4.6개/주가 착과하여 플라스틱온실 대비 반밀폐형온실이 130% 높게착과하였다. 과중 또한 반밀폐형온실과 플라스틱온실이 각각 566.7g/plant와 387g/plant으로 46% 차이를 나타냈다. 이상의 결과로 냉방이 가능한 반밀폐형온실에서 파프리카를 재배할 경우 일반 플라스틱온실보다 광합성과 생육이 양호하였음을 확인할 수 있었다. 따라서, 반밀폐형온실의 냉방 효율을 위한 요소기술을 일반 플리스틱온실에 적용하여 여름철 고온기를 극복한다면 수확량 및 품질 향상을 통한 농가소득 증대가 가능해질 것으로 기대된다.

In this study, experiments were conducted to investigate the effects of high- temperature stress on paprika in a semi-closed greenhouse where cooling is available and a normal plastic greenhouse. Paprika grown in a semi-closed greenhouse in which geothermal cooling is provided showed a significantly higher speed of photosynthesis than paprika grown in a 3-layer plastic greenhouse in which there is no cooling system. It suggests that the photosynthesis speed of paprika in a plastic house decreases owing to high temperature stress. Plant height increased by 13cm more in the semi-closed greenhouse, and the size of leaf showed similar growth speed until the 2nd week after transplanting, however, after 3 weeks, the semi-closed greenhouse showed a big difference by 47% compared with the plastic greenhouse. In terms of the fruit count, the semi-closed greenhouse had 10.6 fruits/plant and the plastic greenhouse had 4.6 fruits/plant, indicating that the semi-closed greenhouse had a higher number of fruits by 130% than the plastic greenhouse. The fruit weight also presented a difference between the semi-closed greenhouse and the plastic greenhouse by 46%, which is 566.7g/plant and 387g/plant, respectively. According to the above mentioned results, it was validated that when paprika is cultivated in a semi-closed greenhouse where a cooling system is applied, photosynthesis and growth were better than in the normal plastic greenhouse. Thus, if the hot summer season is overcome by applying the elemental technologies for the cooling system to the normal plastic greenhouse, farm income may increase through improvement in the yield and quality.
