1, variety: Common varieties include Wuspore No.5, Jinong 1 1 and Xide 89.
2. Sowing date: The suitable fruiting temperature of Pleurotus ostreatus is10-18℃, and the optimum growth temperature of mycelium is 25-28℃. Due to the heat of fermentation and growth, the temperature in the fungus bag is generally 3-7℃ higher than the air temperature. Therefore, when the temperature is stable at18-22℃ in autumn, it is the best inoculation period for Pleurotus ostreatus. Generally, it is from the end of September to the middle of 10. According to different varieties and market demand, the inoculation period can be advanced and postponed appropriately, and the late autumn inoculation can be from the middle of 10 to the middle of10/month.
3. The formula of cultivation material: cottonseed hulls 87.6%, bran 5%, gypsum 2%, lime 3%, calcium superphosphate 2%, urea 0.3%, carbendazim 0. 1%, triacontanol 40 ml per 100 kg dry material, and the ratio of material to water is1:1.4. 4. Production of cultivation materials: after mixing the prepared materials with water, pile them into piles with width 1 m, height 1 m and unlimited length, and then cover them with plastic film for heat preservation and moisture retention. After 2-3 days, the pile temperature can be raised to about 60℃, and the pile can be turned over once a day and 2-3 times. After each turn, the surface of the material should be sprayed with 1000 times of beta-cypermethrin or 400 times of dichlorvos to kill insects. Generally, after 4-5 days of fermentation, the temperature can be lowered in bulk (2-3 hours in late autumn), and when the feed temperature drops to about 30℃, it can be bagged and inoculated.
5. Bagging and sowing: (1) Making cultivation bags. Use polyethylene tube material with a folding diameter of 22 cm and a thickness of 0.03 mm to cut into 48 cm long material bags. Three rows of air holes are punched on the bag with a large sewing needle, with 9 holes in each row. The positions of air holes are 100 mm from the bag head and 1 row in the middle of the bag. Fasten the bag with a pin before loading. (2) sowing. First, break the pollution-free age-appropriate strains into red dates for later use. Inoculation mostly adopts the layer inoculation method of four layers of bacteria (or five layers of bacteria). The thickness of the culture material at both ends of the bag is1-2cm, the middle material layer is evenly distributed, and the strains stick to the bag wall. The sowing amount generally accounts for15-20% of the dry material weight. After sowing the seeds, make a hole with a diameter of 2 cm longitudinally in the middle, and then seal it with a pin. Generally, the loading height is 30-33cm, the dry material per bag is1-1.5kg, and the wet weight is not less than 2.3kg. The tightness of loading should be elastic, not soft and not firm.
Pathogen management:
1, spawning site and discharge mode:1Inoculation before mid-October can spawn outdoors. After sowing, move the fungus bags to a cool and ventilated place, and arrange them in rows, with the height not exceeding 5 floors. After1mid-October, bacteria need to grow indoors, and the height of bag discharge can be increased to 7-8 floors.
2. Stacking: Stacking should be done once every 7 days during the spawning period, so as to balance spawning.
Mushroom period management:
1, bagging and palletizing: 20-30 days after sowing, hyphae can be full of bagging and palletized in the shed, with a general palletizing height of 8-11layer.
2. Heat preservation: The optimum temperature for fruiting is10-18℃, and the temperature in the early fruiting stage is relatively high, mainly by shading and ventilation. In late autumn and early winter, the room temperature is suitable, and the heat preservation and cooling are combined. After entering the winter, heat preservation is the main way to increase the temperature, and the greenhouse temperature should be artificially increased below 5℃.
3. Moisturizing: The suitable humidity for fruiting is 85-95%. Humidification measures of mushroom shed are as follows: First, irrigate the furrow once every 7 days. The second is to spray water on the inner wall of the shed and the air with a sprayer, and it is not allowed to spray on the mushroom buds of the fungus bag when spraying.
4. Ventilation: At the early stage of fruiting, the outdoor temperature is high, and when the temperature in the mushroom shed is above 15℃, it is mainly ventilated day and night. Generally, at night, the plastic films on the north and south sides of the shed will be erected at 3-6 places with a height of 20-30 cm. In late autumn and winter, when the temperature in the mushroom shed drops below 15℃, it is enough to ventilate1-2 hours every morning and noon. Pleurotus ostreatus belongs to variable temperature fruiting, so attention should be paid to artificially widening the temperature difference in management.
5, adjust the light: the growth and development of Pleurotus ostreatus needs enough scattered light to avoid direct light, and it is appropriate to adjust the light in the shed with shading objects to read newspapers everywhere during the day.
6. Pay attention to hydrating and topdressing in the later stage. After Agaricus blazei produces one or two tidal mushrooms, the water and nutrients in the bag are consumed greatly. Combined with water supplement, pay attention to adding nutrients: urea 0.4-0.7kg, sugar or glucose 0.2-0.5kg, magnesium sulfate 0. 1 kg, triacontanol 40ml, lime 0.5-1.0kg per 100kg of water. Appropriate amount of micro-fertilizer can also be added if conditions permit, such as Fenggubao and Fenggufeng. The specific method of supplementing water and topdressing: put the prepared nutrient solution into a big pot or barrel, put it at a height of more than 2 meters from the ground, and use a special water injector to inject water bag by bag, with 0.4-0.75 kg per bag. After the first water injection, water is injected once for every mushroom, usually 3-4 times.
Disease control:
Myxomycetes are the main miscellaneous bacteria in the fruiting body growth stage of Pleurotus ostreatus, and the fungus bags infected with Myxomycetes should be disposed of in time after being found. The main pests are mushroom flies and red spiders, which can be controlled by 25% bactericidal ester dilution 1000 times, or by aluminum phosphide fumigation. When controlling pests, we should pay special attention not to spray pesticides on mushrooms, so we should use drugs before or after picking mushrooms.
Harvesting and processing:
When the largest mushroom umbrella in a cluster of Agaricus blazei reaches 28-30 mm, it is the best time to pick the cluster of Agaricus blazei. After picking mushrooms, cut off the mushroom feet with culture materials, then tear the Pleurotus ostreatus one by one, and place them separately according to the level. If fresh mushrooms are sold, they can be bagged for sale. If it is salted, it needs to be cooked in time, and mixed evenly according to the ratio of 0.4 kg of salt per kg of cooked mushrooms, and put it into a big pot for salt pickling, which can be sold after 15 days.
