Planting methods and techniques of Pleurotus ostreatus: how to cultivate Pleurotus ostreatus? Analysis on the planting profit of Pleurotus ostreatus

Pleurotus ostreatus is a kind of edible mushroom which is favored by domestic and foreign markets and has health effect. Baiyu mushroom is a kind of edible mushroom which is favored by domestic and foreign markets and has the function of health care. Baiyu mushroom is now a best-selling fungus. The cost of planting is also very low, so what about the profit? How to grow white jade mushrooms? Let's take a look at it.

I) raw material treatment: first add the proportion of Ig Huawei R50 microbial accelerant stack material per kilogram of sawdust, soak IOg accelerant in 2-5L water for 24 hours, then evenly mix and spray or pour on the IOkg stack, spray while stirring to ensure that the same batch of sawdust fermentation is uniform, the stacking temperature is kept at 40-60 °C, fermentation for 30-60 days can be used as a spare cultivation material.

2) mixing material: add fully fermented sawdust and cottonseed hull, corncob and other ingredients to dry mix 20-30min, add appropriate amount of water, wet mix 30_50min, the water content in the culture material reaches 60% 65%, pH is between 6-7.

3) loading: the full automatic loading line is used for loading, and the cultivation bottle of 850CC is used. The weight of each bottle is between 500g and 600g, and then the bottle is placed neatly in the sterilizer for sterilization.

4) Steam sterilization: adopt automatic computer controlled sterilization equipment, vacuum before sterilization, keep it for 2-4 hours when the steam temperature reaches 110C to 121oC, exhaust automatically after sterilization, and pull the material bottle into the cooling chamber when the furnace pressure is OMPa.

5) cooling inoculation: the cleanliness of both the cooling room and the inoculation room is 100 degrees. When the temperature of the material in the bottle drops to 15-20 °C, it is inoculated on the automatic inoculation line, and the inoculation amount is 13-17g / bottle.

6) Culture: after the completion of inoculation, it was transferred to the culture room for bacteria culture, the temperature of the culture process was maintained at 20-29 °C, the mycelium grew for 25-40 days, the CO2 concentration was maintained at 2000-3000ppm, and the humidity was 55-85%. Scratching bacteria can be carried out after a culture cycle of 70-95 days. 7) scratching bacteria: a culture bottle full of mycelium scrapes off the bacteria with a width of 4-8mm on the surface to form a hilly shape with a protuberance in the middle, and then inject water into the surface with a water injection of 20-30ml.

8) Fertility: the computer automatic control bionic system is used to monitor the growth and development of Pleurotus ostreatus, and provide the best conditions suitable for growth and development. The temperature is set at 14-18 °C, the humidity is 95%, the concentration of CO2 is 2000-3500ppm, and the light intensity is 500-1500Lux (a mixture of blue and white light). The birth cycle is 20-25 days.

9) harvesting: according to the requirements of the product quality standard, when the diameter of the cap is I. 0-1. When 5cm and stalk length were harvested at 5. 5-10cm, the bioconversion rate reached 85% Mel 90%.

From the analysis of the market price of Pleurotus ostreatus, its price is at a relatively high level compared with other fungi. The common price of white jade mushrooms in the market is 6 to 8 yuan per jin, but due to different regions, the market price will also vary greatly. in some areas, the market price of white jade mushrooms is as high as 20 or 30 yuan per catty. In some areas, the price of white jade mushrooms is only four or five yuan per jin, but white jade mushrooms are very popular fungi no matter where they are.

The planting cost of Pleurotus ostreatus is very low, and its total cost is generally no more than 3,000 yuan. In the case of passing the planting technology, the output of Baiyu mushroom is relatively OK. On average, it can produce about 2,000 jin of white jade mushroom per mu. Calculated according to the market price of 6 yuan, it can make a profit of about 12000. After removing the cost of planting, it can also earn eight or nine thousand yuan, so the profit margin is very large.
