Causes of death of Pleurotus ostreatus and its control methods

Pleurotus ostreatus is one of the common edible fungi planted in China. With the continuous development of planting technology, the yield of greenhouse and factory planting is also relatively high. But for growers, what they fear most is the emergence of various diseases and dead mushrooms in Pleurotus ostreatus. What causes it? Let's take a look.

First, the cause of death of Pleurotus ostreatus

There are many reasons for the death of Pleurotus ostreatus, such as continuous high temperature, long-term lack of nutrients, poor ventilation, improper watering, inappropriate soil pH value, aging of hyphae, high density of mushroom production, invasion of diseases and insect pests, improper use of pesticides and other factors will cause the death of Pleurotus ostreatus, which are more common in the cultivation of Pleurotus ostreatus.

II. Prevention and control methods

1. Select excellent bacteria.

Seed selection is the key point of plant Pleurotus ostreatus, only the strains with good mycelial growth ability are more likely to obtain high yield after planting, and can prevent the phenomenon of dead mushroom very well at the same time. In addition, we should pay attention to the sanitary work of the culture room, maintain clear air, pay attention to the temperature in the mushroom shed during the breeding period, make sure it grows at a suitable temperature, and dispose of the inferior or poorly growing bacteria in time.

2. Master the correct planting time

Pleurotus ostreatus is widely planted in China, so its planting time should be determined according to the local climate and geographical environment. For example, North China and Central and South China generally prepare culture materials in August and sow in September. Planting too early and too late is not conducive to the growth of Pleurotus ostreatus, and the phenomenon of dead mushroom is very likely.

3. Do a good job of ventilation

Sufficient oxygen must be maintained during the growth of Pleurotus ostreatus. If the concentration of carbon dioxide in the room is too high, the fruiting body of Pleurotus ostreatus may not grow and grow, and the concentration of carbon dioxide continues to rise. then the possibility of death of Pleurotus ostreatus will be very high.

4. Correct use of water

The amount of water used by Pleurotus ostreatus must be determined according to the climate, the amount of mushroom production and other factors, and should not be too much or too little. If you are in cloudy and rainy weather for a long time, you should pay attention to watering, and at the same time, you should rarely spray or not spray water. If it is a high temperature season in summer, because the evaporation is large and the air is relatively dry, you need to spray more water appropriately to play the role of cooling and humidification.

The above is the introduction of the causes and control methods of the death of Pleurotus ostreatus. I hope it can help you. I want to know more about it. Please pay attention to us.
