Symptoms of several major diseases of Pleurotus ostreatus
The main results are as follows: (1) White rot: the pathogen is verrucosporium, which harms the fruiting body and causes decay and rotten smell after mushroom body pollution.
(2) Brown spot: the pathogen is Trichoderma verticillarum. After its spores infect the fruiting body of Pleurotus ostreatus, brown spots are formed on the cover, which gradually expand and produce gray-white depressions. After the damage of the mushroom body, it becomes deformed, the stalk of the mushroom is swollen or curved, but does not rot, and finally dries up and dies.
(3) Mucor soft rot: the pathogen is Mucor. Generally, it occurs when the fruiting body is not harvested in time after the fruiting body is fully mature, and the mushroom room is in the environment of high temperature and humidity or stagnant water on the bed for a long time, the diseased fruiting body shows light yellow or light brown water-stained soft rot, which usually starts from the base of the fungal stalk, and finally causes the whole fruiting body to show water-stained soft rot, the surface is sticky and slippery, and there is no rotten smell.
(4) Pleurotus ostreatus malformation: it belongs to physiological disease. It occurs under the condition of poor ventilation, high concentration of carbon dioxide or lack of light, dysplasia after fruiting body differentiation, often with long feet, small or even aseptic cap, or "V" shaped mushroom. Secondly, there are deformities caused by virus, its stalk swelling in the form of near-ball burning bottle shape, and finally the mushroom body atrophied, spongy, resulting in death.
(5) Young mushroom atrophy and dry blight: caused by physiological lack of water and relatively low humidity of air. The young mushroom grows thin, shrinks and dies from top to bottom, and the fruiting body is wrinkled and shrunken.

Processing and storage of Pleurotus ostreatus
In addition to some fresh sales, Pleurotus ostreatus can also be processed and stored, which can be processed by many methods, including drying and salinization, which are briefly described as follows: 1. The drying method generally adopts shade drying, sun drying, drying and so on. Insolation is an economical and equipment-free method. It can also be dried in the shade or dried by the wind. However, this method is limited by weather conditions. The drying method is commonly used in production, build a drying room, the heat source can be charcoal fire or coal cake, drying with reference to the form of the drying building. The room is non-smoking and should be equipped with exhaust equipment. Start the temperature control at

What is the cause of the deformity of Pleurotus ostreatus
The occurrence of Pleurotus ostreatus deformity should have a lot to do with the great temperature difference between day and night. Since the beginning of winter, the temperature has been on the low side. In order to allow Pleurotus ostreatus to grow rapidly, many mushroom farmers deliberately raise the temperature of the greenhouse during the day. Generally speaking, after about three o'clock in the afternoon, the temperature in the shed begins to drop rapidly because of continued ventilation. As most of the currently used mushroom sheds are relatively simple and have poor heat preservation performance, at night, the temperature can drop to 4-5 ℃ or even lower, because the temperature is low and the material temperature is low. Therefore, the ability of mycelium to transport nutrients is very poor, and the temperature is higher in a short time during the day.
