The present invention relates to a modular mushroom cultivation system using natural light. According to the present invention, the modular mushroom cultivation system using natural light includes: a container having a door on the front side； multiple natural light emitting units installed and fixed on the ceiling of the container at predetermined intervals； a natural light diffusing means for diffusing the light by interconnecting natural light emitting units； air conditioning ventilation device installed in a rear wall in the container； mushroom culture sterilizing devices installed on a side of the air conditioning ventilation device continuously to use chlorine dioxide； and a mushroom cultivation unit mounting mushroom medium trays on an installation frame arranged on both sides with reference to the width-direction center in the container and the mushroom culture sterilizing devices to cultivate mushrooms. The natural light emitting units and natural light diffusing means are used to supply natural light smoothly for cultivating mushrooms. The mushroom culture sterilizing devices use chlorine dioxide, sulfuric acid, and wood vinegar to promote growth of the mushrooms and sterilize the mushrooms, thereby maximizing the productivity of the mushroom within a predetermined space. The air conditioning ventilation device supplies hot or cold air into the container while purifying the air in order to circulate the inner and outer air through external and internal air ventilation devices included thereby. Accordingly, the modular mushroom cultivation system can optimize the environment in the container for cultivating mushrooms, thereby reliably maintaining the optimized environment.본 발명은 자연광을 이용한 모듈러 버섯 재배 시스템에 관한 것으로, 본 발명은 전방 측에 출입문을 갖는 컨테이너, 컨테이너의 천장에 일정간격을 가지고 설치고정되는 자연광 조명유닛, 다수의 자연광 조명유닛 하단을 상호 연결하여 광을 확산시키는 자연광 확산수단, 컨테이너 내부 후방 벽체에 설치되는 공기조화겸 환기장치, 공기조화겸 환기장치 일 측에 연이어 설치되는 이산화염소를 이용한 버섯 배지 살균장치와 버섯 배지 살균장치 및 컨테이너 내부의 폭 방향 중앙을 기준으로 양측으로 구비되는 설치프레임 상에 버섯 재배를 위해 버
