Cultivation techniques of Pleurotus ostreatus

Pleurotus ostreatus is the most common mushroom vegetable in our life, and the market demand in our country is very large. Pleurotus ostreatus has various effects such as dispelling wind and dispelling cold, relaxing muscles and activating collaterals, which can enhance the immune function of the human body. Now with the expansion of the market demand of Pleurotus ostreatus, the cultivation area of Pleurotus ostreatus is also expanding. So how to cultivate Pleurotus ostreatus? The following editor brings you the cultivation techniques of Pleurotus ostreatus, let's have a look!

1. Mushroom room nourishment

The mushroom house can choose a vacant house or a basement. Mushroom houses should be guaranteed to have high topography, adequate water sources around them, and strong drainage and irrigation capacity. The walls of the mushroom house should be thick to improve the heat preservation and moisture retention of the mushroom house. Then set up a bed frame in the mushroom room, the bed frame can not lean against the wall, and keep the aisle around 60cm. Then it was disinfected and fumigated with formaldehyde, potassium permanganate and so on. Then mix the nourishment with cottonseed shell, lime and other substances, dissolve the lime with water, pour on the cottonseed shell, step on the cottonseed shell and turn and mix the cottonseed shell to ensure that the water content of the cottonseed shell is uniform.

2. Sowing seeds at the right time

The sowing method of Pleurotus ostreatus is mainly layer sowing. First of all, spread a layer of plastic film on the mushroom bed, then spread a layer of nutrients on the plastic film, then sprinkle Pleurotus ostreatus seeds on the nutrients, and then spread the nutrients on the seeds for circulation, and then flatten and compact the nutrients. Before we sow the seeds, we must first remove the bacteria and put them in a clean container. After hand disinfection, the bacteria are broken into lumps the size of longan, and then sown. Finally, after all sowing, cover the film, improve the moisturizing ability, avoid being contaminated by miscellaneous bacteria, generally can be sown in August-April.

3. Management of germicidal period

During the growth and development of Pleurotus ostreatus hyphae, the main thing is to adjust the temperature and moisturize, so as to avoid being polluted by miscellaneous bacteria. About 10 days after sowing, the temperature of the mushroom room should be reduced to 15 degrees. When the strain germinates and begins to expand, we should always check the temperature of the nutrients so that they are not too high. If the temperature is too high, the film should be opened in time to ventilate and cool down. Cover the film after the appropriate temperature. If there is miscellaneous bacterial contamination, then sprinkle the right amount of lime powder in the place where the miscellaneous bacteria grow. The application is kept at about 65%. Generally, the whole culture material will be full of hyphae after sowing for about a month.

4. Management of mushroom production period

After the mycelium is full, we have to ventilate for about an hour every day, increasing the temperature difference and promoting the formation of fruiting bodies as soon as possible. Then do a good job of sleeping with you according to the actual situation, and increase the humidity to about 80%. For mature mycelia, it is easy to form gray buds. Spray properly at this time to maintain indoor humidity. Do not spray water on the material surface, otherwise it will affect the growth of the buds and lead to the death of young mushrooms. The temperature is maintained at about 16-17 degrees, and the growth rate is accelerated after the buds are formed. 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 we are planting, we should also do a good job of fertilization to improve the yield and quality of Pleurotus ostreatus. That's all for today's introduction. This article is for reference only. I hope it can help you all.
