What are the causes and control methods of Pleurotus ostreatus?

The cultivation of Pleurotus ostreatus is relatively common in our country, and now the planting technology is developing continuously, and the yield of greenhouse and factory planting is relatively high. The economic benefit of Pleurotus ostreatus is good, not only has high nutritional value, but also has the advantages of short growth cycle and easy management. For growers, what they fear most is the emergence of all kinds of diseases or dead mushrooms. Next, let's take a look at the causes and control methods of the death of Pleurotus ostreatus.

1. The cause of the death of Pleurotus ostreatus

Many growers respond that dead mushrooms often occur when planting twin mushrooms. What is the cause of that? Generally, factors such as continuous high temperature weather, long-term lack of nutrients, poor ventilation conditions, incorrect methods of water use, discomfort of soil pH, aging of hyphae, overdensity and high position of mushroom production, invasion of diseases and pests, abuse of pesticides and other factors can lead to the death of Pleurotus ostreatus.

Second, what are the control methods of Pleurotus ostreatus?

1. Select excellent bacteria.

Seed selection is a key point in the cultivation of Pleurotus ostreatus, because only the strains with good mycelial growth ability are more likely to obtain high yield. The culture medium must have enough nutrients, pay attention to the sanitary work of the culture room, and keep the indoor air fresh. During the period of strain cultivation, we should pay attention to observe the temperature in the greenhouse of Pleurotus ostreatus, and make sure it grows at a suitable temperature. If poor quality or poor growth of bacteria are found, they must be disposed of in time.

2. The training materials must be fully invested.

In the production process of Pleurotus ostreatus, there must be sufficient nutrients in order to make Pleurotus ostreatus grow normally and obtain high yield and high quality. If Pleurotus ostreatus is short of nutrients for a long time, it is easy to die, so it is very critical to configure and cultivate, and the stacking and fermentation of culture materials must be done carefully. in this way, it is more conducive to reduce the occurrence of dead mushrooms caused by lack of nutrients.

3. Master the correct planting time

Pleurotus ostreatus is widely planted in China, so the planting time of Pleurotus ostreatus should be determined according to the local climate and geographical conditions. For example, in the central and southern part of North China, materials are generally prepared in August and sown in September. If you plant Pleurotus ostreatus too early or too late, it is possible to grow dead mushrooms.

4. do a good job of ventilation in the mushroom shed.

The growth of Pleurotus ostreatus must maintain sufficient oxygen, if the indoor carbon dioxide is too high, it will cause the fruiting body of Pleurotus ostreatus can not grow normally. The main reason is that the ventilation condition in the mushroom shed is not good, the carbon dioxide is too thick, and the phenomenon of dead mushroom appears.

5. Correct use of water

The amount of water used for Pleurotus ostreatus must be determined according to climate, mushroom production and other factors. For example, if you are in cloudy and rainy weather for a long time, you should spray less water, and if it is hot in summer, you should spray more water.

In summary, the phenomenon of death of Pleurotus ostreatus is relatively common, growers can refer to the above measures to do a good job of prevention.
