Cultivation of Pleurotus ostreatus: how to cultivate Pleurotus ostreatus in orchard?

How to cultivate big ball cover mushroom in orchard? Please introduce the method of cultivating Pleurotus ostreatus in orchard can refer to the following methods: using pure rice straw or wheat straw to cultivate Pleurotus ostreatus in orchard with raw material, the yield of fresh mushroom is 10m ~ 15kg per square meter, 100m ~ 2 per mu and 1000m ~ 1500kg. The economic benefit is very considerable. And the raw materials for growing mushrooms are returned to the field on the spot to improve the soil, which is the first-class fertilizer in the orchard. Production season arrangement of Pleurotus ostreatus: generally speaking, in the northern region, the sowing temperature in early autumn is the most suitable, the mycelium grows fast, the mushroom produces early, the yield is high, the mushroom peak is around New Year's Day and the Spring Festival, the fresh market is good, and the economic benefit is high. Orchard selection and mushroom bed arrangement: the orchard cultivating big ball cover mushroom should sit north and south, avoid the wind and sun; the soil is fertile and loose; it is close to water source, convenient for drainage and irrigation, no water and semi-shaded natural environment after rain, and avoid low-lying land and over-wet sites. The design of the mushroom bed is generally based on the size of the open space between the natural rows, leaving a sidewalk in the middle of the row, relying on both sides of the fruit tree to form a tortoise-backed fungus bed. The bed is 25 meters high and 30 centimeters high, and its length and width depend on the size between the rows of the orchard. Before sowing, use lime powder, carbendazim and other drugs to kill insects, sterilize and disinfect the bacterial bed and its surroundings. Straw selection and treatment: choose fresh, dry, golden, mildew-free, strong medium and late straw (wheat straw can also be used). The selected rice and wheat straw were first sunburned in the sun for 2 days to reduce the incidence of diseases and insect pests, then soaked in clean water or 3% lime water for 2 days, accumulated and fermented and leached the excess water to make the grass stem dewaxed and softened to facilitate mycelium colonization and germination and feed growth. Big ball cover mushroom spreading sowing: when the heap temperature drops below 30 degrees Celsius and the water content reaches 70%-75%, it can be spread and sown. Each square meter of pure rice, wheat straw (dry material weight) 20Me 25kg, according to the length and width of 14 × 70cm, height 2530cm trapezoidal pile, spread one layer of grass sow one layer of bacteria, a total of three layers of forage, sow two layers of bacteria, the sowing amount is 15LV 20kg (according to dry material), the top layer is covered with a layer of wet rice straw, then covered with 1 cm thick humus soil as a water protective layer, the soil is covered with straw curtains or old sacks, heat preservation and moisturizing It is beneficial to the occurrence of bacteria. Management of the inoculation period of Pleurotus ostreatus: the temperature of the stack is controlled at 22 degrees Celsius, when the temperature is more than 30 degrees Celsius, the upper part of the haystack can be opened or drilled to cool down; if the temperature of the pile is too low, the cover should be thickened or covered with film to increase the temperature and keep warm. The water content of the culture material is kept at 70%, 75%, and the air relative humidity is 85%, 85%, 90%. Generally do not spray water directly to the bacterial bed forage within 20 days, you only need to keep the material pile cover moist. After 20 days, you can spray water appropriately according to the weather conditions and keep the air humidity above 85%. Covering soil of Pleurotus ostreatus: under normal circumstances, the hyphae germinated in 3 days after sowing, and extended to the material and around 7 days later, the hyphae were white and branched obviously, and the hyphae could grow through the material layer in about 25 days. At this time, the material surface should be covered with 3mi 4cm thick soil. It is required to be high in humus and granular. Break and insolate before use, mix in appropriate amount of lime powder and grain husk, and disinfect and kill insects with formaldehyde. Appropriate amount of water should be sprayed after covering the soil, and it is appropriate to wet the soil. Mushrooms can be produced about 15 days after covering the soil. Management of mushroom emergence period of Pleurotus ostreatus: when white buds appear on the surface of the soil layer, atomized water should be sprayed to the border bed every morning and evening. Because the body of Pleurotus ostreatus is larger and the water demand is higher, so the water management is very important during the period of mushroom emergence. The principle is to spray frequently, spray more mushrooms, spray less mushrooms, spray more in sunny days, spray less or not in cloudy and rainy days. Ventilation 2 times a day, about 30 minutes each time. The harvest of Pleurotus ostreatus: when the bacterial membrane has just broken and the inner roll of the bacterial cover is not opened, it is harvested in time. When picking, the fingers gently twist the base of the mushroom handle, and then pull it up after loosening, do not drive the surrounding small mushrooms, so as not to damage the young mushrooms and affect the yield of lower tide mushrooms. After harvesting a batch of mushrooms, spray water on the material pile once, cover with plastic film to raise bacteria, and harvest 3 batches of mushrooms in about 10 days.
