Why are oyster mushrooms growing poorly? The reasons are here

Some oyster mushroom growers wrote in saying that the oyster mushrooms they cultivated were not growing as well as they had hoped, and they wanted to know where exactly the problem lies. Below is an analysis and a few reminders regarding some problems commonly seen in cultivation:

The first reason may be that the ambient temperature and the substrate temperature are unsuitable. Being above or below the fruiting temperature range of the cultivated variety will both lead to the phenomenon of no fruiting, or of no normal fruiting after the first flush has been harvested and the crop turns to the next flush.

The second reason is poor ventilation in the mushroom shed. Poor oxygen supply and excessively high carbon dioxide concentration are both unfavorable to fruiting; when oxygen is severely lacking, large numbers of mushroom buds will shrivel and be suffocated to death.

The third reason is improper watering methods. If too much water is used when watering, and it is sprayed directly onto the substrate and young mushrooms, and if the doors and windows are closed during watering, the substrate will become waterlogged, causing the mycelium to suffocate and die. At the same time, because water accumulates for a long time on the caps of the young mushrooms and they absorb a large amount of water, this easily creates conditions for bacterial diseases to break out on a large scale.

The last reason is the occurrence of pests and diseases. Because the substrate is improperly selected and treated, and the mushroom house, mushroom shed and casing soil are not disinfected or not thoroughly disinfected, pests and diseases are even more likely to occur, especially in old mushroom houses and old mushroom sheds that have been used for many years. After pests invade, they will feed heavily on oyster mushroom mycelium and fruiting bodies, causing them to break apart, lose water and die. In severe cases of pest and disease damage, there will be no fruiting, or after fruiting the mushrooms will shrivel, turn yellow, and finally rot and die. Therefore, you must carefully investigate the cause and adopt appropriate solutions.
