Clinker cultivation of Pleurotus ostreatus
1. The preparation and selection of culture materials should be fresh, mildew-free, uniform in thickness and remove impurities. Put the raw materials together in proportion and mix evenly, then stir with water, the water content is controlled at 60%, there is a slight water stain in the fingers, but the water does not flow out. And bag it.
two。 The sterilization was carried out in high pressure cabinet for 2 hours after 120 ℃ and steam sterilization for 4 hours after 100 ℃ steam steaming. You can also use a steamer to sterilize, first inject water into the steamer, connect the steamer on the pan, and press the top cover tightly. The top layer was put in the atmosphere and then sterilized for 10 to 15 hours.
3. Inoculation places, personnel, equipment to be disinfected; cooling room and inoculation room per cubic meter with 15 grams of sulfur or 5 grams of potassium permanganate plus 10 ml formaldehyde fumigation, conditions can be sterilized with ultraviolet lamps. Personnel and instruments were disinfected with 75% alcohol and 0.1% potassium permanganate. After disinfection, the inoculation began when the temperature of the feed was lower than 30 ℃.
4. Culture period management culture room to build a simple culture rack, can also be "product" shelf stacking, or stacked into a bacterial wall culture, pay attention to the number of layers of stacking is not too high to prevent bad bacteria and burning bacteria. The culture room should also be disinfected before use.
The temperature was controlled at 20-28 ℃, and the high temperature affected the quality of mycelium. Properly reduce the relative humidity of the air to prevent the growth of miscellaneous bacteria. No light was needed in the culture stage, and the strong light inhibited the growth of mycelium. The growth of mycelium needs fresh air, which is ventilated 2 or 3 times a day.
5. The management of mushroom production requires the stimulation of temperature difference, and the temperature difference between day and night of 8-10 ℃ is beneficial to the differentiation of mushroom buds. After mushroom production, the temperature is controlled at 18: 22 ℃, the air relative humidity is controlled at 85% and 90%, scattered light is given and ventilation is increased.

First, the choice of mushroom bed should choose to avoid the wind and the sun, close to the water source, smooth drainage, less harm to poultry and livestock in the open land or cultivated land, or the forest clearing in the orchard to dig the mushroom bed. The mushroom bed is north-south, about 10 cm deep, 1 m wide and arbitrary in length. Leave a cement ridge about 10 centimeters wide or a small ditch in the middle of the bed. After digging the mushroom bed, disinfect it with 1% lime water or lime powder. 2. The preparation of culture materials for Pleurotus ostreatus is rich in culture resources, such as cottonseed shell, wheat straw, rice straw, sawdust, bagasse, corncob and rapeseed shell, but cottonseed shell.
