Abstract

This study was conducted to provide basic data needed to calculate the crop loads for the greenhouse design. Four countries’ crop loads for greenhouse structures were compared and the crop loads were measured directly and analyzed for various greenhouse crops, including tomato, strawberry, cucumber, and eggplant. According to the analysis results of four country’s standards for the design crop loads, it was judged that the new design crop loads suit for greenhouse crops in our country should be suggested because our standards just used the design crop loads of other countries. The maximum crop loads per plant of tomato, cucumber, eggplant, and strawberry were 3.9, 0.75, 1.9 and 2.1 kgf·plant-1, respectively. The crop load per unit area of tomato was 8.5 kgf·m-2, which was much greater than the cucumber and eggplant’s crop load of 2.1 and 2.4 kgf·m-2 respectively. The crop loads of tomato and cucumber, suggested by the greenhouse structure design standard of Korea, is 15 kgf·m-2, which is far greater than the values suggested by this research. It was judged that this was because our standard just used the Dutch standard, our crop load standard should be reviewed considering this difference. The crop load of strawberry, including the growing bed, was 21.0 kgf·m-2, which was much greater than the crop load in the Dutch standard.

본 연구에서는 온실의 구조설계용 작물하중을 산정하 는데 필요한 기초자료를 제공하기 위하여 각국의 온실구 조설계용 작물하중 기준들을 비교분석하고 여러 가지 온 실작물들에 대하여 작물하중을 직접 측정하고 분석하였 다. 설계 작물하중에 대한 각국의 기준들을 비교분석한 결과 나라들 마다 서로 많은 차이를 보여주고 있으며, 우리나라 기준들은 외국의 기준들을 그대로 인용하고 있 는 것으로 나타나 우리나라 실정에 맞는 작물하중 기준 이 제시될 필요가 있다고 판단된다. 최대 주당 작물하중 이 토마토는 두 가지 온실에서 각각 3.3kgf·plant-1와 3.9kgf·plant-1로 나타났고, 오이는 0.75kgf·plant-1, 가지는 1.9kgf·plant-1, 딸기는 재배베드를 포함하여 2.1kgf·plant-1 으로 나타났다. 단위면적당 작물하중은 토마토가 평균 8.5kgf·m-2으로 나타났고, 오이와 가지는 각각 2.1kgf·m-2 과 2.4kgf·m-2으로 토마토의 하중보다 훨씬 낮게 나타났 다. 우리나라 온실설계기준에 제시된 작물하중은 토마토 와 오이의 경우 15kgf·m-2으로 본 연구에서 측정된 값보 다 훨씬 높았다. 우리나라의 설계기준이 네덜란드의 기 준을 그대로 인용한 것으로 판단되기 때문에 이러한 차 이를 고려하여 우리나라의 작물하중 설계기준에 대한 재 검토가 이루어져야 할 것으로 판단된다. 딸기의 작물하 중은 행잉베드를 포함한 중량이 21.0kgf·m-2로 네덜란드 의 설계기준인 30kgf·m-2보다 훨씬 작았다.
