Abstract
The root-zone environment is an important factor to the plant growth and it is closely related to the thermal characteristics of the root media. In this study thermal characteristics of root media with ambient environmental conditions were analyzed. The temperatures of nutrient solution as well as inside air of culture bed were measured in Nutrient Film Technique(NFT) and Deep Flow Technique(DFT) systems, and also the temperatures of root media measured in aggregate culture systems , The temperature of nutrient solution of NFT system with as low as 3
본 실험은 배지의 종류 및 환경조건에 대하여 배지의 온도변화 특성을 분석하는 것을 목적으로 하였다. NFT DFT, 슬라브형 성형암면, 면상암면, 펄라이트 배지를 사용하는 순환식 양액재배시스템을 구축하였다. NFT와DFT시스템은 양액 및 재배조 내의 공기온도를 측정하였고, 고형배지는 배지온도를 측정 .비교하였다. NFT시스탬의 양액 공급유량을 3
