Abstract

This study evaluated the effect of polyolefine greenhouse covering film on growth of lettuce and cucumber. The growth of lettuce and cucumber plants under conventional film (polyethylene plus ethylenevinyl acetate, PE + EVA) and polyolefine (PO) film were evaluated in a greenhouse. The physical qualities of PO film, such as tensile strength and tear strength, were stronger than conventional PE + EVA film. PO film showed 4% higher transmission performance in photosynthetic active radiation (PAR) than PE + EVA film. The average day and night temperature in greenhouse under PO film were $1.5^{\circ}C$ and $0.8^{\circ}C$ higher but there was no significant difference in relative humidity compared with conventional film. Chlorophyll content of lettuce and cucumber plants grown under PO film were higher than conventional film. Growth characteristics; plant height, leaf area, fresh weight and dry weight of cucumber was shown better for PO film. The yields of cucumber and lettuce was increased 14.0% and 13.6% respectively, when the crops were grown under PO covering film greenhouse.

본 연구는 비닐하우스 피복재인 폴리오레핀(PO)계 필름의 효과를 구명하고자 관행의 피복필름(PE + EVA)과 비교하여 피복재별 물리적 특성과 상추와 오이의 생육 및 수량을 검토하였다. 인장강도, 인열강도 등 피복재의 물리적 특성은 일반필름보다 PO필름이 우수하였다. 400~700 nm의 광합성유효광의 투과율은 일반필름에 비해 PO필름이 4.1% 높았고, 전체 광선투과율(300~1,100 nm)도 PO필름이 4.3% 높았다. 하우스 내의 주간 평균기온은 일반필름보다 PO필름이 $1.5^{\circ}C$ 높았고, 야간 평균기온도 PO필름이 $0.8^{\circ}C$ 높게 유지되었다. 주야간 상대습도는 필름 간에 유의적 차이가 없었다. 엽록소 함량은 오이의 경우 필름 간 유의적 차이는 없었으나 일반필름에 비해 PO필름이 엽록소 a가 약간 높았으며, 상추는 PO필름이 일반필름보다 유의하게 높았다. 수확기 오이 생육에 있어서 초장, 엽면적, 생체중 및 건물중 모두 일반필름보다 PO필름을 피복한 하우스에서 크고 무거웠다. 수확한 오이의 과실 수량은 일반필름에 비해 PO필름이 14.0% 높았고, 상추 수량도 일반필름보다 PO필름이 13.6% 높았다.
