Pleurotus ostreatus is the most common mushroom vegetable in our life, and its market demand in China is very large. Pleurotus ostreatus has various functions such as expelling wind and cold, relaxing muscles and activating collaterals, and can enhance the immune function of human body. Now with the expansion of the market demand for Pleurotus ostreatus, the cultivation area of Pleurotus ostreatus is also expanding. So how should Pleurotus ostreatus be cultivated? Here are the cultivation techniques of Pleurotus ostreatus for everyone. Let's take a look!
1, mushroom room nutrients
The mushroom house can choose an empty house or a basement. The mushroom house should be guaranteed to have a high terrain, with sufficient water around it and strong irrigation and drainage capacity. The wall of the mushroom room should be thick to improve the heat preservation and moisture retention of the mushroom room. Then set up a bedstead in the mushroom room. The bedstead has unreliable walls and a walkway of about 60cm is reserved. Then disinfected and fumigated with formaldehyde and potassium permanganate. Then the cottonseed hull, lime and other substances are mixed with nutrients, and after the lime is dissolved in water, it is poured on the cottonseed hull, and the cottonseed hull is trampled while pouring, so as to ensure the uniform water content of the cottonseed hull.
2, timely sowing
The main sowing method of Pleurotus ostreatus is layer sowing. First, lay a plastic film on the mushroom bed, then lay a layer of nutrients on the plastic film, then spread Pleurotus ostreatus seeds on the nutrients, and then lay nutrients on the seeds, in this cycle, and then level and compact the nutrients. Before sowing, we should first take out the strains and put them in a clean container. After hand disinfection, the strains are broken into eye-size blocks, and then they are sown. Finally, after all the seeds are sown, cover the film to improve the moisturizing ability and avoid being polluted by miscellaneous bacteria. Generally, seeds can be sown in August-April.
3. Management of the outbreak period
During the growth and development of Pleurotus ostreatus mycelium, it is mainly necessary to do a good job of temperature regulation and moisture preservation to avoid contamination by miscellaneous bacteria. After sowing 10 days, the temperature of the mushroom house should be reduced to 15 degrees. When the strain germinates and begins to expand and grow, we should always check the temperature of the nutrient, not too high. If the temperature is too high, the film should be opened in time to cool down. Cover the film after the temperature is suitable. If there is mixed bacteria pollution, then sprinkle a proper amount of lime powder on the position where the mixed bacteria grow. The application rate is kept at about 65%. Generally, after sowing for about one month, the whole culture material will grow full of hyphae.
4. Management of fruiting period
After the mycelium is full, we should ventilate for about an hour every day to increase the temperature difference and promote the formation of fruiting bodies as soon as possible. Then do a good job of accompanying sleep according to the actual situation and increase the humidity to about 80%. For mature mycelium, it is easy to form gray-white bacterial buds. At this time, it is necessary to spray properly to maintain indoor humidity. Do not spray water on the material surface, otherwise it will affect the growth of mushroom buds and lead to the death of young mushrooms. The temperature is kept at about 16- 17 degrees, and the growth rate is accelerated after the formation of the bacterial bud pile. At this time, the humidity should be increased by about 90%, and the temperature should be about 15 degrees.
The above is a brief introduction to the cultivation techniques of Pleurotus ostreatus. When planting, we should also do a good job of fertilization to improve the yield and quality of Pleurotus ostreatus.
