  • 비닐이나 유리로 피복되어 있는 원예재배시설은 저온, 강우 등의 불량환경을 극복하여 작물의 생산성을 높이는 데 크게 이바지해 왔다. 그러나 여름철 고온기에 강광의 유입은 직접적 작물 스트레스는 물론 시설 내 온도를 과도하게 상승시켜 작물생육에 악영향을 미친다. 이 때문에 일반적으로 환기와 차광에 의존하여 시설 내 온도상승을 억제하고 있으나 어려움이 많다. 이에 원예재배시설 내 온도 및 광환경을 개선하기 위하여 개발된 유동차광 냉각시스템을 소개하고자 한다.

  • In order to evaluate the effect of soil salinity and culturing conditions including compost application and vinyl mulching on the maintenance of ridge and the growth of upland crops, three crops such as corn, soybean and sweet potato were experimented by using three or four cultivars of crops in the Saemangeum reclaimed tidal land. Average soil salinity before seeding was 2 dS $m^{-1}$, which was low enough for general upland crops to grow. However, high soil EC more than 16 dS $m^{-1}$ was observed in some parts of the experimented field. In the experiment, it was concluded that growth retardation and yield reduction of summer upland crops might be from severe erosion of ridge, soil compaction, flooding or wet soil condition and high salinity of some parts, and then these deteriorations were possibly improved for good crop growth and yield increase by compost application and vinyl mulching cultivation in the Saemangeum reclaimed tidal land.
