Common physiological diseases of Pleurotus ostreatus and their control methods

Physiological diseases of Pleurotus ostreatus, also known as non-infectious diseases, are diseases that can not be metabolized normally by edible fungi caused by non-immersive pathogens. The general cause of the disease is caused by abnormal growth environment of Pleurotus ostreatus, such as light, temperature, ventilation and so on. Let's take a look at the common physiological diseases of Pleurotus ostreatus and their control methods.

1. Pleurotus ostreatus tall foot disease

The tall foot disease of Pleurotus ostreatus, also known as Pleurotus ostreatus and Pleurotus ostreatus, is that after its primordium has grown, the differentiation of the fruiting body is abnormal, the cap is deformed, and the cap cannot be formed or the cap is very small, but the stalk is slender. The commercial value of this kind of Pleurotus ostreatus is very low, so the economic benefits of growers will be affected.

The occurrence of tall foot disease of Pleurotus ostreatus is because the formation of the primordium of Pleurotus ostreatus does not need a lot of oxygen, but if there is no good ventilation management in the mushroom shed, it will cause serious hypoxia, so it will lead to abnormal development of the cap and grow into a long handle shape. If the light in the mushroom shed is too weak, it will also aggravate the disease.

Therefore, when a large number of Pleurotus ostreatus primordium is formed, it is necessary to do a good job of ventilation in the mushroom shed to ensure that there is sufficient oxygen and no large amount of carbon dioxide.

2. Pleurotus ostreatus with tumor cover

Pleurotus ostreatus usually appears in the growth period of Pleurotus ostreatus fruiting body, and there will be granular or tumor-like protruding parts on the top of the cap. If the disease is more serious, it will make it very difficult for the cap to differentiate and can not form a normal and complete cap. It is also possible that the cap will shrink, and the whole cap will harden and stop growing. Among the many varieties, black Pleurotus ostreatus varieties are more likely to suffer from Pleurotus ostreatus tumor cover disease.

The main reason for Pleurotus ostreatus to suffer from the disease is that the temperature of fruiting body differentiation is very low and it is in a low temperature environment for a long time, which leads to the lack of growth ability of the surface cells of Pleurotus ostreatus cap.

Therefore, when planting Pleurotus ostreatus, it is necessary to do a good job of heat preservation and warming in the mushroom shed in advance, and the temperature in the mushroom shed must not be lower than the growth bottom temperature of Pleurotus ostreatus. If there is a certain temperature difference between day and night, the primordium differentiation, development and growth of Pleurotus ostreatus will be normal.

3. Pleurotus ostreatus atrophy

Pleurotus ostreatus atrophy usually occurs in the early growth stage of Pleurotus ostreatus. When Pleurotus ostreatus grows up and appears yellow, swollen or shrunken or dry, it may stop growing and then rot. In this case, it is impossible to go on the market to sell, which is a serious loss for growers.

There are several reasons for the disease. it may be that the humidity is too high when the fruiting body grows, or there is water sprayed on the small mushroom body, hindering its respiration. It is also possible that the mushroom body of Pleurotus ostreatus is dry and short of water for a long time in a ventilated environment, which will lead to its death.

So usually to control the humidity of the mushroom shed at about 80%, do not let the wind blow directly on the top of Pleurotus ostreatus.
