Oyster Mushroom
Oyster Mushroom
Scientific name (Pluerotus spp) Oyster mushroom is a kind of wood decay group native to dead trees of broad-leaved trees, and is called 'Aspen mushroom' because it grows mainly on dead trees of broad-leaved trees such as Italian poplar and cottonwood in autumn. Due to its wide temperature adaptation range, it is widely distributed throughout the world including Korea. It is called Oyster Mushroom because it looks like an oyster coming out of the sea.
Morphological characteristics of oyster mushrooms
The cap of oyster mushroom is 43-200mm in size, hemispherical in the early stages, but becomes kidney-shaped, clam-shaped, and often funnel-shaped as it grows. It becomes light gray, has excellent absorbency and is smooth. The tissue is relatively thick, flexible, elastic, flesh-like, white, taste, aroma, and soft, and the texture is particularly good when chewing. Wrinkles descending from the stem to the stem, often continuing to the base of the stem, with 1 to 3 types of rather flat and short wrinkles, white to pale yellow, and the edge of the wrinkle is smooth. The surface of the stalk is white, with vertical and uncertain lines, and the upper part is often densely covered with white short hyphal hairs, and the stalk is full, white, and fleshy.

How to grow
Before the 1970s, oyster mushrooms were cultivated by cutting broad-leaved trees such as oaks and cottonwoods, inoculating seed fungi into them, and cultivating them in the open field. With the spread of fungal bed cultivation technology, production increased rapidly. As the demand for mushrooms has increased since the 1990s, technology that can grow year-round by artificially adjusting the growth environment such as temperature and humidity suitable for mushroom growth indoors has been disseminated, and the number of farms using boxes, bags, bottles, etc. It is a trend.
Mycelium cultivation
Fungal bed cultivation is generally a method of cultivating rice straw or waste cotton fermented on it by installing shelves with a width of 1.2 m and a length of 15 m in about 4 stages in a simple cultivation house, and waste cotton is mainly used as a medium material.
Bottle cultivation
Bottle cultivation literally means various stages such as inlet bottling, sterilization, inoculation, cultivation, and growth by mixing sawdust as the main material in a plastic bottle-shaped container of 850 ~ 1100cc and nutrient sources such as cottonseed meal, beet pulp, rice bran, and wheat bran. It is an intensive cultivation method that mass-produces high-quality mushrooms by performing automated mechanical work and artificially adjusting the environment in a room equipped with air conditioning facilities.

King Oyster mushroom
King oyster mushroom was classified as pine family in 1975 and reclassified as oyster mushroom family in 1986, and is an oyster mushroom that was named large oyster mushroom.
Morphological characteristics of king oyster mushrooms
At the beginning of the development of the fruiting body, the shape of the young mushroom is oval in the stem, plump in the center, and small in the cap, like a snowman or trumpet. The flesh of the stem is thick (2~3cm) and the mycelial layer is dense, so the meat quality is excellent and the taste is excellent, and the taste is almost similar to that of wild mushrooms. In artificial cultivation, the length of the stem is 3~12cm long and the color is white. However, the cap is smaller than the stem (about 3-10 cm), the color is light gray or dark ocher, and the cap part has a bulging shape in fully matured state.
