The introduction and popularization of Pleurotus ostreatus in recent years shows that Pleurotus ostreatus has a very broad development prospect. First of all, the cultivation technology is simple and extensive, can be directly cultivated with raw materials, has a strong anti-impurity ability, easy to achieve success. Secondly, the source of cultivation raw materials is rich, which can grow on all kinds of straw culture materials (such as rice straw, wheat straw, flax straw, etc.). In the vast rural areas of our country, it can be used as a main measure to deal with straw. The waste after cultivation can be directly returned to the field to improve the soil and increase fertility. Third, Pleurotus ostreatus has strong stress resistance and can adapt to a wide range of temperature. it can produce mushrooms in the range of 4-30 ℃ and can survive the winter naturally in Fujian and Guangdong provinces. Due to the long suitable season, it is beneficial to adjust the listing of other mushrooms or vegetables in the off-season. Fourth, Pleurotus ostreatus is easily accepted by consumers as a new product on the market because of its high yield, low production cost and rich nutrition. The main results are as follows: 1. The fruiting body is solitary, clustered or grouped, medium to large, and a single mushroom mass can weigh several kilograms. The cap is nearly hemispherical, posterior flattened, 5cm in diameter. The cap is fleshy and the surface is slightly sticky when wet. The young fruiting body is white at first, often with small nipple protuberances. As the fruiting body grows, the cap gradually changes to reddish brown to wine reddish brown or dark brown, and fades to grayish brown when it is ripe. Some fungi have fibrous scales on the lid, which gradually disappear with the growth and maturity of the fruiting body. Pleurotus ostreatus is rolled in at the edge of the cap, often with fragments of the curtain. The fungus is thick and white. The bacterial folds are straight and dense, initially dirty white, then turn gray-white, spread flat with the cover, and gradually become brown or purplish black. The stalk is nearly cylindrical, slightly inflated near the base, the stalk is 5-20 cm long, 0.5-4 cm thick, dirty white above the ring, nearly smooth, with yellow fine stripes below the ring. The stalk was myelinated in the early stage and gradually hollow after maturity. The bacterial ring is membranous, thick or double-layer, located in the middle and upper part of the stalk, white or nearly white, with rough stripes on it, deeply divided into several fragments, and the lobes are rolled up slightly at the apex, easy to fall off, and often disappear on the mature fruiting body. The spores are purple-brown, smooth, brown, oval and punctate. There are obvious bud holes at the top, thick walls, pleated cysts clavate, and a small protuberance at the top. 2. From spring to autumn, Pleurotus ostreatus grows in the forest, on the grass on the edge of the forest or on the roadside, garden, garbage dump, sawdust heap or cattle and horse dung heap in the pasture. Artificial cultivation in Fujian Province except for no mushrooms from July to September, mushrooms can grow in other months, but there are more mushrooms from late October to early December and from March to early April and grow fast. Wild Pleurotus ostreatus grows on the deciduous layer under the broad-leaved forest on the Qinghai-Tibet Plateau and in the coniferous and broad-leaved mixed forest in Panxi area. 3. Pleurotus ostreatus is distributed in Europe, North America, Asia and other places in nature. It is cultivated in European countries, such as Poland, Germany, the Netherlands, the Czech Republic and so on. Wild Pleurotus ostreatus is distributed in Yunnan, Sichuan, Xizang, Jilin and other places. Click to get more planting techniques of Pleurotus ostreatus
