How does agaricus cultivation manage?

How to manage the cultivation of Pleurotus ostreatus? What is there to pay attention to? Please also have the help of netizens to introduce the management methods of cultivating Pleurotus ostreatus, which are listed below for netizens' reference. 1. Nutrient management: Pleurotus ostreatus is a saprophytic fungus, which completely depends on the nutrients in the culture material for growth and development. The carbon sources available for Pleurotus ostreatus are glucose, sucrose, maltose, polypentose, starch, vitamins, hemicellulose and lignin, which must be decomposed into simple carbohydrates by other microorganisms and enzymes secreted by mushroom hyphae before they can be absorbed and utilized. The nitrogen sources that can be used by Pleurotus ostreatus are urea, ammonium salt, peptone, amino acid and so on. The growth of mushroom also needs certain mineral elements such as phosphorus, potassium, calcium and trace elements such as iron and molybdenum. Therefore, in addition to the main raw materials such as dung and grass, urea, ammonium sulfate, calcium superphosphate and other fertilizers as well as gypsum and lime should be added according to a certain proportion to meet the needs of the growth and development of Pleurotus ostreatus. 2. Temperature control: the temperature of mycelium growth of Pleurotus ostreatus is between 5 ℃ and 33 ℃, and the optimum temperature is 23 ℃ 25 ℃, which grows slowly below 5 ℃. Although the mycelium grows fast when it is higher than 25 ℃, it is slender and weak, and it is easy to senescence. The mycelium over 32 ℃ is easy to senescence or yellowing and inverting, so that it stops growing. The fruiting body could be formed at 7 ℃ and 22 ℃, and the optimum temperature was 15 ℃. In this temperature range, the fruiting period lasted only about 3 months. The mushroom emergence period can last for 6 months in the range of 13Mel 18 ℃. The fruiting body formed at lower temperature is white, stout, mushroom-shaped garden, thick meat and high yield. During the formation of fruiting bodies, especially from young buds to young mushrooms, the temperature can only maintain the original temperature and not rise, otherwise it will cause a large number of thin-skinned Pleurotus ostreatus or a large number of mushroom buds to shrink and die. Because the hyphae are essentially like interconnected "tubes", at lower temperatures, the hyphae kink each other to form mushroom buds, and nutrients are transported to the mushroom buds for growth and development with the help of the flow of protoplasts in the mycelium cells. If the temperature picks up, especially when the higher temperature is too long, the hyphae send nutrients from the mushroom buds to the surrounding hyphae for mycelium spread and growth, resulting in the death of a large number of young buds. The best temperature of spore emission is 18 ℃ and 20 ℃. If the temperature is more than 27 Mel, it is a quite mature fruiting body and will not produce spores. The best temperature for spore germination is 24 ℃ 26 min. Too high or too low will prolong the germination time or not. 3. The control of moisture and humidity of culture material: the water needed during the growth period of Pleurotus ostreatus comes from the air relative humidity of culture material covering soil and cultivation place. In the mycelial growth stage of Pleurotus ostreatus, the water content of the culture material is required to be 60%. The mycelium growth of less than 50% is slow, the villous hyphae are numerous and slender, and it is not easy to form fruiting bodies; when the oxygen content in the culture material is higher than 70%, the mycelium growth of Pleurotus ostreatus will also be affected. The humidity of the overlying soil layer should be kept at about 18%. Over-drying will affect the development of mycelium and young mushrooms, and reduce the quality of Pleurotus ostreatus. During the period of mushroom emergence, the air relative humidity should be controlled between 85% and 90%. If more than 95%, water droplets will be retained on the lid for a long time, which is prone to various bacterial spots; if less than 70%, the cover surface will harden, even crack, and it is easy to be hollow; if less than 50%, the mushroom buds will wither and die and stop producing mushrooms. 4. management of air in the room: Pleurotus ostreatus is a kind of aerobic fungus, which needs plenty of fresh air no matter during the mycelial growth stage or during the fruiting body. In the germicidal stage, the concentration of CO2 should be controlled within 0.034 mol 0.1%. If the mushroom stage is more than 0.1%, the cap is small, the stalk is slender, and it is easy to open the umbrella; if the concentration of CO2 is higher than 0.5%, it will inhibit the differentiation of the fruiting body, stop the mushroom, and the villous hyphae in the culture material will grow vigorously and grow to the surface of the covered soil. Therefore, it should be ventilated in time to provide sufficient fresh air. 5. Light control: the growth of Pleurotus ostreatus does not need light, and the whole process can be carried out in complete darkness. The fruiting bodies grown in the dark environment are white in color, round in shape and good in quality. But when the fruiting body is generated, it is best to have the stimulation of scattered light, at this time, the light of the mushroom room should not be too bright, such as the surface of the mushroom body is easy to dry and turn yellow, and the quality decreases. 6. The pH (PH value) of the culture material: the hyphae of Pleurotus ostreatus can grow between PH 5.8 Mel 8.0, and the most suitable PH value is about 7. Because the mycelium will produce carbonic acid and oxalic acid in the process of growth, the accumulation of these organic acids in the culture material and overlying soil layer will gradually make the environment of mycelium life sour and the PH value decrease. Therefore, when sowing, the PH value of the culture material should be adjusted to 7.8mur8.0, and the PH value of soil particles should be adjusted to about 8.0, which is not only beneficial to the growth of mycelium, but also inhibit the occurrence of mold.
