How to choose the strain of Pleurotus ostreatus? How to cultivate it?

Nowadays, there are more and more delicacies on the table, and mushroom food is also very popular with the public. Mushrooms such as Pleurotus ostreatus sell well in the market. They are delicious, nutritious and rich in protein. How to choose the strain of Pleurotus ostreatus? How to cultivate it? Friends who want to know, please read the following!

First, how to select the strain of elm yellow mushroom?

When selecting the strains of Pleurotus ostreatus, try to choose Yuhuang 83520 and Yuhuang 2, which have strong anti-impurity ability and fast mycelium growth, so the mushrooms are more high quality and delicious. Strains can generally be purchased nearby if they are not available locally. You can order from non-local bacteria factory. You need to make a reservation in advance. It is generally arrived through logistics and distribution.

Second, how to cultivate Pleurotus ostreatus?

1. Cultivation season

According to the temperature required for the differentiation and development of the fruiting body of Tricholoma thunbergii, it can be cultivated in autumn, winter and spring in the north of China, while it is better in autumn and winter in the south.

2. Cultivation form

There are three forms of artificial cultivation of Pleurotus ostreatus: raw meal, fermented material and clinker. Because of its strong impurity resistance and rapid mycelial growth, raw meal and fermented material are mostly used in our country.

3. Culture material and stacking

Commonly used formula one: 100kg of cottonseed shell, 2kg of lime, the ratio of material to water is 1 ∶ 1.3-1.5. This formula can be cultivated with raw materials or fermented materials. Commonly used formula 2: 70 kg of corncob, 15 kg of wheat bran, 15 kg of rotten chicken manure, 4 kg of quicklime (the quality of lime varies from place to place, and the amount of lime can be slightly changed), 0.3 kg of urea, 1 kg of gypsum and about 65% water content. The construction of culture materials should be 1 meter high, 1.2 meters wide and 1.5 meters wide and unlimited in length. After building the pile, gently press the material meter, and then use a thicker stick to evenly open the stomata on the pile from top to bottom to avoid anaerobic fermentation. When the temperature in the reactor rises to about 65 ℃ at 20 cm, the reactor will be turned over for 12 hours. When turning the pile, it is necessary to exchange the position of the culture material up and down, inside and outside, and mix evenly. After turning the pile for the first time, it was maintained for 1-2 days when the material temperature rose above 60 ℃, and then turned back and forth for a total of 3-4 times. When the corncob turns dark brown and has a fermented flavor, the fermentation ends.

4. Germ management

The temperature of the germicidal place should not exceed 25 ℃, and the relative humidity of the air should be 60% to 70%. At the same time, we should pay attention to shading and ventilation. The temperature of the shed should be controlled below 28 ℃, and over 28 ℃, attention should be paid to bulk cooling or ventilation cooling. One week later, the mycelium germination was examined. If it is found that the mycelium does not germinate, it should be replanted; if a small amount of miscellaneous bacteria infection is found, the ventilation and cooling of the bacteria room should be strengthened to control or restrain the development of miscellaneous bacteria. If the temperature is too low, it is necessary to keep warm and warm up to ensure the normal growth and development of hyphae. Generally, the mycelium can grow into the whole bag in 25-30 days.

5. Mushroom production management

After the mycelium grew in the bag and maintained for another 3-7 days, the mushroom production management could be carried out. The mushroom production management of mushroom wall is often used in production, and the palletizing method of fungus wall is the same as that of Pleurotus ostreatus. After the mushroom wall is built, the top of the wall is irrigated with water, the temperature of the mushroom (shed) is maintained at 15: 20 ℃, the air humidity is 85% and 95%, the temperature difference is widened, pay attention to ventilation and give some scattered light stimulation, about a week later, a large number of buds will appear. During the period of mushroom emergence, spray 2 and 3 times to the ground and space of the cultivation place, and pay attention to ventilation and keep the air fresh. It usually takes 8 days and 10 days from budding to harvest.

Well, the above is all the content that the editor wants to share with you. If you have an idea to grow elm yellow mushrooms to eat, you must first choose strains with strong anti-impurity ability and fast mycelium growth. Like Yuhuang 83520 and Yuhuang 2, these two are very good. In addition, the editor also shared the detailed cultivation methods to everyone, and found it useful to collect.
