Rare Edible Mushrooms - Pleurotus eryngii is a precious food and medically acceptable fungus. Its fleshy fleshy, crisp texture, dense and compact stipe, strong milky white and rich nutrition are listed as the 21st century. One of the most potent edible fungi. Due to the high pollution rate, low bioconversion rate, and large fluctuations in production, the number and yield of cultivated plants are not stable, and they must master their biological characteristics and adopt scientific and technical measures to achieve their desired goals. 1. Nutrition Pleurotus eryngii is a kind of edible fungus that has strong ability to decompose cellulose and lignin. It is suitable for many growth substrates, such as sawdust, cottonseed hull, corn cob, and bean stalk. From the results of cultivation experiments, when the content of wood chips in the medium is high, mycelia growth is slow, the growth and development cycle is long, the yield is low, and when the cottonseed husk content is high, the growth is fast. High Yield. The addition of bran or corn flour has a good effect on promoting the growth and development of Pleurotus eryngii and increasing fruit body production. The addition of bean stalk powder can also increase the yield of Pleurotus eryngii. 2. The optimum temperature for the growth of Pleurotus eryngii mycelium is 25°C; the temperature for forming the primordium is 10°C-18°C, the most suitable temperature is 13°C-16°C; the development temperature of the fruiting body is 8°C-20°C, the most The suitable temperature is 10°C-16°C. When the temperature is lower than 10°C or higher than 20°C, it is difficult to produce mushrooms. Therefore, it is very important to select suitable cultivation period for cultivation of Pleurotus eryngii. 3, moisture Pleurotus eryngii mycelial growth stage, the moisture content of culture materials to 60% -65% is appropriate. The ratio of total dry material to water is 1:1.1-1.4, and the relative humidity of air is 60%-70%. The formation and development stage of fruiting bodies requires 85%-95% of air humidity. 4. The requirements of air in the growth stage of Pleurotus eryngii mycelia are not strict. During the growth of mycelia, the carbon dioxide accumulated in the bottle can promote the growth of mycelium. However, in the formation of the primordium, sufficient oxygen is required to promote the occurrence of mushroom buds and rapid growth. The concentration of carbon dioxide in the fruit body growth stage is preferably less than 2000 mg/kg. 5, light Pleurotus eryngii mycelium growth phase does not require light, in a dark culture room, mycelial growth faster. The formation and development of fruiting bodies requires scattered light, suitable light intensity is 500-1000 lux. 6, PH hyphae can grow at PH4-8, the optimum PH6.5-7.5; optimum PH5.5-6.5 mushroom.
