How to grow tea mushroom?

How to grow tea mushroom? Please introduce Pleurotus ostreatus, also known as Pleurotus ostreatus, Pleurotus ostreatus, poplar mushroom and willow matsutake. Under natural conditions, it mostly occurs in spring and autumn, and it can also be cultivated annually under artificial conditions, with crisp cover stalk, strong smell, especially good taste of fungal stalk, and often edible has the effect of lowering blood pressure and cholesterol. Dry fruiting body can treat diseases such as stomach cold, nephritis edema, adverse urination and so on, which is very popular, consumption is increasing day by day, and the market price is high, so mushroom farmers have achieved better economic benefits. The main cultivation techniques are briefly introduced as follows. 1. Biological characteristics 1. Temperature: mycelium growth temperature 5Mel 30 ℃, optimum 21 Mel 28 ℃, fruiting body growth temperature 13 Mel 25 ℃, optimum 22 Mel 24 ℃. Different strains require different requirements, and primordium differentiation does not need temperature difference stimulation. Although the growth effect of relatively low temperature is slow, the pollution is less and the quality of mushroom is high. 2. Moisture and humidity: the water content of the culture medium is 45% and 80%, and the water content of 65% can adapt to the long cultivation period, while the growth is slow. The relative humidity is 65% and 70% in the mycelium growth stage and 85% and 90% in the fruiting body formation. 3. Air: the fungus room should be ventilated intermittently during the mycelial growth stage, and the cultivation room should be ventilated frequently in the fruiting body growth stage, depending on the actual situation. 4. Acidity and alkalinity: suitable for neutral partial acid environment, the mycelium produces little organic acid in the process of metabolism, and the PH value of culture medium does not change much, so the optimum PH value of culture material can be adjusted to 5.5 ~ 6.5. 5. Light: no light is needed for mycelium culture, and 150-1000lx light is needed for the growth of fruiting body. The growth of fruiting body has obvious phototropism, and the products with small cover and long stalk can be obtained under certain conditions, such as Flammulina velutipes cultivation. 2. According to the growth and development characteristics of Pleurotus ostreatus, the mycelium should be cultivated from late February to early April in spring, from mid-April to mid-June, from late August to the end of September in autumn, and from early October to the end of November. Third, the preparation of materials and sites for Pleurotus ostreatus substitute cultivation, the preparation materials include raw materials for the preparation of culture medium, plastic bags and drug elimination. (1) there are mainly two kinds of synthetic material formula: 1. The culture material formula with sawdust as the main material: sawdust 38%, cottonseed shell 35%, wheat bran 15%, corn meal 6%, tea seed cake powder 4%, gypsum 1%, brown sugar 0.5%, potassium dihydrogen phosphate 0.4%, magnesium sulfate 0.1%. 2. The formula of culture material based on cottonseed hull: sawdust 9%, cottonseed hull 75%, wheat bran 15%, calcium sulfate 1%. (2) plastic bags: the specifications of plastic bags for tea mushroom cultivation are 15cm (diameter) × 30cm, or 17cm (diameter) × 33cm. The material in each bag is 0. 6m / L / 0. 8kg. (3) disinfection of the site: before and after discharging, drying and feeding, the mushroom room and site should be disinfected with 800 times carbendazim and 0.5% dichlorvos, and the mushroom room should be fumigated with formaldehyde once to eliminate latent bacteria and pests. Fourth, the operation methods of mixing ingredients, bagging tea tree mushroom culture materials, bagging and bagging Lentinus edodes are basically the same. When bagging, it should be noted that when the stuffing is close to 6 cm of the mouth of the bag, it can be tied. 5. sterilization of tea mushroom culture medium, the method of atmospheric pressure and high temperature sterilization is often used. As most mushroom farmers use large film sterilization stoves, the capacity is controlled at about 3000 bags at a time, and the sterilization temperature standard: from ignition to 100℃, the temperature should be controlled at about 2 ℃ for 3 hours, and after the temperature rises to 100 ℃, it should be kept for 22 hours, that is, about one day and night. 6. Cool the culture bag after inoculation and sterilization. When the temperature drops to 60 ℃, unload the bag and leave the stove while it is hot. When the temperature in the bag drops to normal temperature, it can be transferred to the inoculation process. The procedure of inoculation and disinfection is basically the same as that of bag Lentinus edodes. Seventh, indoor discharge of bacteria culture temperature is controlled at about 22 ℃, strengthen ventilation, pay attention to temperature control and light control. The relative humidity is 70%, and the light should be avoided in the dark. Eighth, cut the bag to promote the bud tea tree mushroom bag culture 50 for 60 days, the mycelium grows full of the bacterial bag, the bacterial bag is full of elasticity, the hyphae secretes pigment and spits yellow water, the hyphae on the surface of the bag is a little brown, that is, the color is changed, the bag is cut at the right time, and the sharp knife is used to cut off the mouth of the bag. The focus of the management of mushroom production is to control temperature, humidity, air, light and stimulation to meet the needs of the growth and development of Pleurotus ostreatus. The air relative humidity is 90% and the temperature is controlled at 20 ℃-28 ℃. In short, the mushroom production management of Pleurotus ostreatus should coordinate the relationship among water, temperature, gas, humidity and light.
