Abstract

There was no difference in total light transmissivity of covering materials. But the light transmittance of J-2 in greenhouse was by 78.25 which was higher than any other film. The high light transmittance of J-2 was come from low water condensation and dust attached in film surface. The ultraviolet light of J-3 was completely intercepted. The ultraviolet transmittance rate of others was from 62 to 76%. In no heating oriental melon cultivation, the air temperature in tunnel was 15 to $21^{\circ}C$ higher than outer, and the soil temperature in tunnel was 20 to $25^{\circ}C$ higher than outer. Air temperature and soil temperature of J-2 were higher than any other film.

피복자재별로 전광선투과율은 차이가 거의 없었으나, 물방울과 먼지의 부착량이 적은 J-2에서 시설 내 광투과율은 78.2%로 가장 높았다. 자외선 투과율이 완전히 차단된 필름은 J-2이었고, 나머지의 자외선 투과율은 $62{\sim}76%$ 정도이었다. 무가온 참외재배시기에 터널 안이 노지보다 기온은 $15{\sim}21^{\circ}C$, 지온은 $20{\sim}25^{\circ}C$ 정도 높았다. 피복자재별로 기온은 $6^{\circ}C$, 지온이 $5^{\circ}C$ 정도 차이가 나타났으며 기온과 지온 모두 J-2 에서 가장 높았다.
