Abstract

This experiment was conducted to investigate the difference among 3-years-used polyolefin films which were J-l, J-2 and J-2 having differences in film thickness, infrared absorption and ultraviolet penetration from Jan. 16, 2006. And 1-year-used polyethylene film K-1 used from Jan. 16, 2009, for covering film of greenhouse for oriental melon cultivation. J-2, J-3 and J-1 films were better for keeping heat in order, and J-2 film was the best in plant growth at early stage. The first blooming and harvesting days in J-2 film were earlier 15 days than those in K-1 film. Chromaticity and soluble solid of harvested fruit in J-2, J-3 and J-1 films were higher than whose in K-1 film. Marketable yields in J-2, J-3 and J-1 films were higher in order.

참외 하우스 피복필름 장기사용을 위하여 필름두께, 적외선 흡수율, 자외선 투과율이 다른 polyolefin계 film(일본산, J-1, J-2, J-3)을 2006년 1월 16일 피복하여 3년 사용한 처리와 우리나라의 참외 재배농가에서 관행으로 사용하는 polyethylene계 film(K-1)을 2009년 1월 16일 피복하여 1년 사용한 처리를 대조로 설치하여 피복필름의 장기사용 가능성을 검토한 결과, 보온성은 J-2 처리에서 가장 높았고 J-3, J-1 순이었으며, 초기생육모 J-2 처리에서 가장 좋았다. 개화 및 수확소요일수는 K-1 처리에 비하여 J-2 처리에서 15일 단축되었다. 과피의 색도 및 당도는 K-1에 비하여 J-2, J-3, J-1 처리에서 높았고 상품과 수량은 J-2, J-3, J-1 처리 순으로 높았다.
