The purpose of the present invention is to provide a method for cultivating oyster mushrooms and a culture medium composition for cultivating oyster mushrooms, which contribute to income increases of mushroom cultivators by giving the vitality of spawns inoculated into a culture medium, preventing the contamination of spoilage bacteria, promoting the growth of mushrooms, and increasing an amount of harvest. A method for cultivating oyster mushrooms according to the present invention comprises: a step of preparing a culture medium comprising sawdust, corncobs, wheat bran, rice bran, and calcium； a step of putting the culture medium into a culture container, sealing the culture container containing the culture medium, heating the culture container to sterilize the culture medium, and cooling the heated culture container to cool the culture medium； a step of inoculating oyster mushroom spawns into the cooled culture medium； a step of performing a dark cultivation process on the oyster mushroom spawns to cultivate mycelia； a step of performing a bright cultivation process on the oyster mushroom mycelia passed through the dark cultivation process； and a step of putting the culture container comprising the bright cultivation process-completed mushroom mycelia into cultivation facilities to cultivate the mushroom mycelia into mushrooms.본 발명은 톱밥, 콘코브, 밀기울, 미강, 및 칼슘을 포함하는 배지를 제조하는 단계； 상기 배지를 배양용기에 담고 밀봉한 후, 살균을 위해 가열하고 냉각하는 단계；.상기 냉각된 배지에 느타리버섯 종균을 접종하는 단계； 상기 느타리버섯 종균을 암배양을 통해 균사체를 배양하는 단계； 상기 암배양을 거친 느타리버섯 균사체를 명배양하는 단계； 및 상기 명배양이 완료된 버섯균사체를 포함하는 배양용기를 재배사에 입사하여 버섯으로 배양하는 단계를 포함하는 느타리버섯의 재배방법을 제공한다.
