Environmental Control of Nutriculture in a Plant Production System Utilization Solar Energy -Investigation of Actual State of the Nutriculture in Korea-

태양에너지를 이용한 식물(植物) 생산(生産) 시스템내의 양액재배(養液栽培) 환경조절(環境調節)에 관(關)한 연구(硏究) -국내(國內) 양액재배(養液栽培) 실행농가(實行農家)의 실태조사(實態調査)-

In order to provide fundamental data for the achievement of safe environmental condition, investigation of the actual state of the nutriculture practices in Korea was carried out. The result obtained are summarized as follows. 1. Cultivation area of nutriculture was 6 ha and culture types included deep flow technique(43%), nutrient film technique(45%), gravel culture(6%), chaff charcoal culture(3%) and rockwool culture(3%). 2. Greenhouses were mostly made of pentite pipe frames and covered by polyethylene film, and culture beds were handy combination of cement blocks, concrete and styrofoam, which were not standard products. 3. Development of nutriculture system appropriate to our actual circumstances and improvement of establishments are required. 4. Since there was not farmhouse that performs the environmental measurement and environmental conditions of cultivation were very limited. sensor applied environmental control technology of nutriculture should be developed.
