초록

본 연구는 인공광 이용형 common ice plant 식물공장 설계를 위한 기초자료를 확보하고자 수행되었다. 인공광 이용형 식물공장에서 작물의 광합성을 위해 필요한 광도는 120~200μmol·m−2·s−1, 탄소 고정률은 0.84nmolCO2·cm−2·s−1 이었다. 1주의 점유 면적 0.0225m2(15×15cm), 광도 200μmol·m−2·s−1, 하루 1,000주 생산을 가정할 경우, 식재 주수는 25,000주, 563m2의 재배면적이 필요하며, 전체 광도는 140,625μmol·s−1가 필요하게 된다. 하루 전력 약 153.2kW 기준으로 약 2,785개의 55W 형광등이 필요하며, 1개월 전기요금은 246만원(농업용 전력(을))이 된다. 또한 조명 설비 비용 2,785만원, 설비 비용 8,356만원과 전체 생산 비용 10,027만원이 소요된다. 재배기간 25일(325일 생산), 상품화율 80%에 따른 1주 당 생산 비용은 인건비 포함하여 약 370원이 된다. 경비 총합, 감가 상각비와 연간 판매수입을 고려해볼 때, 1주당 판매 비 용은 970원 이상으로 판단되었다.

This study was carried out to get the basic data to practically design an artificial light-used plant factory system for common ice plant (Mesembryanthemum crystallinum L.) cultivation. The adequate range of light intensity was 120- 200μmol·m−2·s−1 and the carbon fixed rates was 0.84nmol CO2·cm−2·s−1. When the planting density, light intensity, and yield were 0.0225m2 (15×15cm), 200μmol·m−2·s−1, and 1,000 plants per day, the total number of the plants, cultivated area, and total light intensities were estimated as 25,000 plants, 563m2, and 140,625μmol·s−1, respectively. About 153.2kW with 2,785 fluorescent lights (FL) needed for the electric power and the electricity charges was 2.46 million won for one month. At a harvest rate of 1,000 plants per day in closed-type plant factory, the light installation cost, total installation cost, and total production cost were 27.85, 83.56, and 100.27 million won, respectively. The production cost per plant including labor cost was calculated as 370 won, providing that the cultivation period was 25 days and marketable ratio was 80%. Considering the annual total expenses, incomes, and depreciation cost, the sales cost per plant could be estimated around 970 won or higher.
