A Detailed Guide to Wood Ear Mushroom Cultivation Techniques: Mastering the Key Points of Fungus Bag Management and Fruiting Body Harvesting

The wood ear mushroom is a common gelatinous edible fungus. Its fruiting bodies are elastic, store well after drying, and are a highly popular ingredient on the dining table. At present, artificial cultivation of wood ear mushrooms mainly involves two methods: log cultivation and bag substrate cultivation. Among these, bag substrate cultivation uses sawdust, cottonseed hulls, corn cobs, and other materials as raw materials; it saves labor and materials, produces uniform fruiting bodies, and is the cultivation model commonly adopted today.

To grow wood ear mushrooms, the first priority is proper fungus bag production and mycelium growth management. The culture substrate must be mixed evenly, bagged, and thoroughly sterilized. After inoculation, place the bags in a clean, light-protected environment for culturing, keeping the temperature stable and ventilation good. Generally, after about one month the mycelium will have grown throughout the fungus bags. During the mycelium growth period, the bags should be turned and inspected regularly, and any bags contaminated by competing fungi should be promptly removed and handled to prevent spreading.

Once the mycelium has fully grown, the fruiting stage can begin. The fruiting stage has relatively high water requirements; water must be sprayed to maintain high air humidity, while ventilation should be strengthened and some scattered light provided to promote normal expansion of the fruiting bodies. If the temperature is on the high side or the humidity is too great, soft rot and diseases are likely to occur, so the frequency of ventilation and water spraying should be adjusted flexibly according to weather changes.

When the fruiting bodies are fully expanded, with edges curling inward and beginning to soften, they are ready for harvest. After harvesting, dry them in the sun or by artificial drying for storage. As long as the key steps of sterilization, mycelium growth, and fruiting are well controlled, and production is arranged according to local conditions, wood ear mushroom cultivation can achieve relatively stable results, making it suitable for farmers and mushroom houses with the right conditions to try.
