Causes and Control of abnormal Mushroom Disease of Edible Fungi

Abnormal mushroom disease of edible fungi is also a physiological disease. Edible fungi in the formation of fruiting bodies, if encountered adverse environment and conditions, so that the fruiting bodies can not develop normally, it will produce a variety of deformities. The main features are: the cap is small and thin, the handle is slender, and the umbrella opens early. This phenomenon often occurs after the first stubble of Pleurotus ostreatus and Pleurotus ostreatus, while Lentinus edodes occurs in the first crop. The main causes are high temperature, lack of light, lack of nutrition and so on.

Pleurotus ostreatus mainly occurs during the fruiting body formation of Pleurotus ostreatus, the fruiting body is coral-shaped or the cap is very small, and the root of the stalk is thick. The main reasons are lack of light, poor ventilation, high carbon dioxide content and too little oxygen. The occurrence of fruiting body tilting phenomenon is generally inclined to the bright side, which is due to the phototaxis of fruiting body in the growth process, mainly caused by the uneven light in the mushroom room. The phenomenon of mycelium shrinkage and sometimes even death that often occurs in different growth processes is mainly due to the fact that the bacteria are not robust and do not eat on the new culture material; or the water content of the culture material is not suitable, too dry or too wet; and then the temperature in the material is too high, resulting in burning bacteria, or poor ventilation in the culture material, or the acidity and alkalinity in the culture material is not suitable.

There is only one prevention and control measure, that is, in the production process, every procedure and every process must be carried out scientifically and strictly in accordance with the requirements, so as to avoid adverse consequences of one kind or another, resulting in production failure.
