Abstract

Three leaf vegetables, namely green lettuce, red lettuce (Lactuca sativa) and red-veined chicory (Cichorium intybus) were grown in minigreenhouses covered with two new functional films and conventional polyethylene film (PE). Seedlings of leaf vegetables were transplanted in a plastic troughs filled with soil-perlite mixture. Two functional films were made from polyolefin (PO) material. Measurement of optical characteristics showed that polyolefin films have better transmittance for the photosynthetic active radiation (PAR, 400-700nm) and higher absorptance for the ultraviolet radiation (UV, 300-400nm) in comparison with the conventional PE film. After three months of utilization higher loss in PAR transmittance was observed for conventional PE film. Leaf vegetables growth was enhanced and yield was increased in greenhouses covered by new functional films.

소형 비닐하우스에 2종류의 기능성 필름과 관행의 PE 필름을 피복하고 청치마, 적치마, 치커리 등 3종의 엽채류를 재배하여 기능성필름의 특성을 검토하였다. 2종류의 기능성 필름은 PO(polyorefine)계 수지로 만들어졌으며, 엽채류는 흙과 펄라이트를 혼합한 배지에서 육묘하였다. 필름의 광학적 특성에 있어서 기능성 필름은 관행의 PE 필름과 비교하여 광합성 유효광(400-700nm)의 투과율이 높고 자외선(300-400nm)의 흡수율이 높았다. 피복 3개월 후의 광합성 유효광 투과율의 감소 수준은 기능성필름이 PE필름보다 작았다. 이 같은 요인으로 인해 엽채류의 생육과 수량이 기능성 필름을 피복한 하우스에서 높았다.
