This study was conducted to examine the effect of artificial light source and photoperiod on the growth of leaf lettuce (Lactuca sativa L.) 'Seonhong Jeokchukmyeon' in a closed-type plant production system. Seedlings were grown under 3 light sources, fluorescent lamp (FL, Philips Co. Ltd., the Nethe...

식물공장이란? | 식물공장이란 농작물에 대하여 통제된 일정한 시설 내에서 광, 온도, 습도, 이산화탄소 농도 및 배양액 등의 환경조건을 인공적으로 제어하여 계절이나 장소에 관계없이 자동적으로 연속 생산하는 시스템을 말한다(Takatsuji, 2008). 현재 전세계적으로 식물공장과 관련한 연구가 다각도로 진행되고 있지만 이에 대한 명확한 정의가 정립되지 못하고 있는 실정이다. | |
메탈할라이드등의 장점은? | , 2004). 메탈할라이드등은 파장이 가시광 전반에 분포하여 고압나트륨등보다 식물재배 효과가 우수하다. 하지만 고압나트륨등에 비교하여 발광효율이 낮고 수명이 짧기 때문에 식물공장에 사용하기에는 적합하지 못하다. | |
메탈할라이드등의 단점은? | 메탈할라이드등은 파장이 가시광 전반에 분포하여 고압나트륨등보다 식물재배 효과가 우수하다. 하지만 고압나트륨등에 비교하여 발광효율이 낮고 수명이 짧기 때문에 식물공장에 사용하기에는 적합하지 못하다. 형광등은 식물공장에 많이 사용되는 조명으로 다단식재배에서 식물에 근접조명이 가능하나 발광효율이 20% 정도로 광합성에 유효한 스펙트럼이 적다. |
