Abstract

This study was carried out to develop the technology to manage the growth of mushrooms, which were cultivated based on long-term information obtained from quantified data. In this study, hardware that monitored and controlled the growth environment of the mushroom cultivation house was developed. An algorithm was also developed to grow mushrooms automatically. Environmental management for the growth of mushrooms was carried out using cultivation sites, computers, and smart phones. To manage the environment of the mushroom cultivation house, the environmental management data from farmers cultivating the highest quality mushrooms in Korea were collected and a growth management database was created. On the basis of the database value, the management environment for the test cultivar (hukthali) was controlled at $0.5^{\circ}C$ with 3-7% relative humidity and 10% carbon dioxide concentration. As a result, it was possible to produce mushrooms that were almost similar to those cultivated in farms with the best available technology.

버섯은 관리가 매우 까다로운 작물로 알려져 있다. 그렇기 때문에 버섯을 오랜 기간 재배해 온 농민도 버섯을 재배할 때마다 버섯의 품질이나 생산량에 차이가 발생한다고 한다. 본 연구는 그동안 오랜 경험에 의한 지식으로 재배하던 버섯의 생육관리를 계량화된 데이터를 기반으로 관리하기 위한 기술을 개발하기 위하여 수행되었다. 본 연구에서는 버섯재배사의 생육환경을 원격에서 모니터링하고 제어하기 위한 하드웨어와 버섯을 자동으로 재배할 수 있는 알고리즘을 개발하였다. 버섯의 생육을 위한 환경관리는 재배현장, 컴퓨터, 스마트폰 등을 이용해 할 수 있도록 하였다. 본 연구에서는 국내에서 최고 품질의 버섯을 재배하는 농가의 환경관리데이터를 수집하여 이를 기반으로 생장환경관리 데이터베이스를 만들고, 만들어진 데이터베이스를 기반으로 재배사 내부의 환경이 관리되도록 하였다. 재배품종은 흑타리버섯 이다. 버섯재배를 위한 관리 환경은 데이터베이스 값을 기준으로 온도는 설정값${\pm}0.5^{\circ}C$, 습도는 상한은 설정값+7 %, 하한은 설정값-3 % 수준에서 제어되도록 하였고, 이산화탄소 농도는 설정값${\pm}10%$ 수준에서 제어가 되도록 하였다. 이와 같은 환경에서 버섯을 재배한 결과 수확시 버섯의 생산량이 $193.8{\pm}12.9g$/병으로 최고의 기술을 가진 농가에서 재배하는 것과 거의 동일한 수준의 버섯을 생산할 수 있었다. 따라서 그동안 오랜 경험을 기반으로 관리하던 버섯재배사 환경관리를 센서의 데이터를 기반으로 관리할 수 있을 것으로 판단되었다.
