熱帯気候地域に適した温室被覆材としてのプラスチックフィルムと複層流液被覆 : シミュレーションによる比較研究

抄録

A simulation study was conducted to examine the effects of two types of newly developed plastic films and a fluid-roof cover (hollow-channeled polycarbonate structure with 1.5%, CuSO₄-water solution) on the air, plant and soil temperatures. Closed fluid-roof and ventilated plastic film greenhouses with moist soil were examined at different plant densities on hot sunny days. The results show that at high plant densities the ventilated plastic film greenhouse gave lower soil and plant temperatures than the closed fluid-roof. The plant temperature in the closed fluid-roof greenhouse was unacceptably high at high plant densities. Thus, the plastic films can be used in hot climates as an inexpensive substitute for the fluid-roof cover with complex structure.
