The latest death causes and control methods of young Pleurotus ostreatus

In the production of Pleurotus ostreatus, due to the discomfort of cultivation environment and culture materials, as well as improper management or disastrous weather, small mushrooms often shrink, turn yellow and end in the end, sometimes resulting in the death of young mushrooms in batches, seriously affecting the yield and quality. So what is the cause of death of young Pleurotus ostreatus? Come and have a look with the editor.

1. The temperature is too high

After the formation of the primordium of Pleurotus ostreatus, if the high temperature lasts more than 30 degrees, its cap will gradually wither, resulting in mass death of young mushrooms, seriously affecting the yield. For this situation, it is necessary to reasonably control the temperature of the mushroom shed, and when the temperature is too high during the mushroom production period, well water spraying can be adopted to reduce the temperature of the mushroom shed. If it is cultivated outdoors, thick straw curtains or straw can be used to cover the mushroom shed to avoid sunlight. At the same time, attention should be paid to frequent ventilation and ventilation to lower the temperature in the mushroom shed as much as possible.

2. Lack of moisture

After the young buds of Pleurotus ostreatus are formed, if the relative air humidity in the mushroom or shed is less than 80%, then the young mushrooms will wither and die due to lack of water, because Pleurotus ostreatus has higher requirements for air humidity during the mushroom emergence period. Therefore, after budding, water should be sprayed 4-5 times a day in the mushroom shed to keep the air humidity at about 90%, so that the young mushrooms can develop well. However, in spraying water, we should also pay attention to doing as little, evenly and finely as possible. If the amount of water spraying is large, it will also lead to the decay and death of young mushrooms, so we must pay attention to it.

3. Excessive spraying of water

Pleurotus ostreatus in the fruiting body expansion period, at this time is also necessary to maintain a high air humidity, if too much water spray, it will lead to rapid expansion of the fruiting body, extremely prone to edema, eventually yellowing and ulceration, and extremely easy to be infected with bacteria and die. Therefore, when spraying water in the mushroom shed or mushroom room, the water should be evenly sprayed on the ground and the surrounding walls, not directly on the fruiting body, and at the same time, we should master the correct amount of water spraying and should not spray too much.

4. Poor ventilation

In addition to temperature and humidity, ventilation is also one of the important factors affecting the growth and development of young mushrooms. When the concentration of carbon dioxide in the room exceeds 0.5%, young mushrooms are very easy to form fists or big feet with small thick covers. Therefore, in normal times, we should pay attention to ventilation to ensure that the indoor air is fresh, especially in the high temperature season, so as not to form a large number of deformed mushrooms.
