Abstract

Shading with silver-coated strips in combination with water spraying over the roof was more effective than others in lowering air-temperatures while the soil temperatures were more efficiently lowered by the silver-coated PE film in combination with water-flowing treatment on the soil surface. Significantly better growth and higher yield of spinach were recorded in the plots having lower soil termperatures. Whitewash spray with lime mixture resulted in higher yield of spinach as compared to the white water-soluble painting, possibly because of the better light penetration toward the end of the growing season by the natural weather off phenomenon.

은색 차광망에 지붕살수방법을 병용하였을 경우 타처리에 비하여 약 3℃의 실온 하강효과를 보였으나 지온에서는 은색차광망에 지표유수처리를 병용한 것이 더 효과적으로 약 2~3℃의 지온 하강효과를 보였다. 시금치의 생육과 수량은 은색차광망+지표유수구에서 가장 양호하였다. 여름철 하우스 polyethylene film에 도료피복 및 석회도포 처리 등의 효과비교에서는 시금치 생육이 진전됨에 따라 자연 분해 등에 의해 광투과율이 점차로 높아지는 것으로 판단되는 석회 도포처리구가 타처리에 비하여 시금치의 생육과 수량이 우수하였다.
