절화 장미 스마트팜과 관행농가의 시설현황과 2018년 11월 부터 2019년 1월까지의 재배환경 및 절화 품질을 비교하였다. 두 농가 모두 연동 플라스틱 온실이었고, 스마트팜은 자동제어시스템이 설치되어 있었으나, 일부만 제어가 되고 있었다. 농가의 재배환경을 분석한 결과, 스마트팜의 시설 내 온도는 계절에 관계없이 일정하게 유지되고 있었으나 광량과 습도는 두 농가 모두 적정 값에 미치지 못하는 것으로 나타났다. 재배 품종의 절화 특성을 조사하여 품질을 분석한 결과, 스마트 팜의 ‘Soprano’ 품종은 11월부터 1월까지 절화수명이 약 8.6~ 9.8일로 유사하게 나타났으며 ‘Victoria’ 품종은 1월에 통계적으로 유의차 있게 다소 수명이 단축되었으나 1월을 제외하고는 약 8.2~8.6일로 수명이 비슷한 것으로 조사되었다. 관행농가의 ‘3D’와 ‘Kensington Garden’ 품종은 절화수명이 일정하게 나타나지 않았다. 절화수명에서 품종별 유의적 차이는 없었고 월별 유의적 차이만 나타났는데 이는 품질 차이가 아닌 온실 환경 때문이라고 판단된다. 스마트팜은 CCTV나 어플리케이션을 통해 실시간으로 온실관리를 할 수 있어 재배환경이 다소 일정하게 유지되었으며, 추후 ICT(Information and Communications Technologies) 기술 확대로 완전자동제어시스템이 이루어져 균일한 품질의 절화 장미가 생산될 수 있도록 해야 될 것으로 판단된다.

In the present study, the facilities and qualities of cut roses in a smart farm and greenhouse were compared from November 2018 to January 2019. Both facilities comprised multi-span plastic films; however, the smart farm was equipped with additional automatic control systems for monitoring temperature and humidity, CO2, and nutriculture solution. After analyzing the environment of the farms, the temperature in the smart farm was maintained constant regardless of the season; however, light intensity and humidity were below the optimum value in both farms. The 'Soprano' cultivar from the smart farm exhibited similar longevity from November 2018 to January 2019, ranging from 8.6 to 9.8 days. In addition, the longevity of the 'Victoria' cultivar from the smart farm was similar, ranging from approximately 8.2 to 8.6 days; however, the longevity in January significantly decreased. The longevity of cultivars '3D' and 'Kensington Garden' from the greenhouse were not consistent. Therefore, there were no significant differences in the longevity of cultivars and quality of roses; however, monthly longevity significantly varied because of the different environments of both farms. The automatic control systems in the smart farm could have facilitated the constant maintenance of good quality cut roses. The smart farm could monitor and deliver real-time information on crops, soil, etc. using cameras or cell phone applications. Further studies on the numerous aspects of smart technologies could improve the production of high quality cut roses. Future studies will attempt to apply information and communication technologies using completely automated control systems. The present study demonstrated variations in the quality of cut roses between a smart farm and greenhouse.
