Simple fresh-keeping Technology of Pleurotus ostreatus
Under general conditions, Pleurotus ostreatus is difficult to store and its shelf life is short. After picking for 2 days, the freshness of Pleurotus ostreatus decreased greatly, and the mushroom noodles turned yellow and appeared peculiar smell. During the peak period of mushroom production, a large number of fresh mushrooms are concentrated on the market, resulting in a big drop in mushroom prices; on the other hand, in the off-season and cities far away from mushroom areas, there is no goods to sell because of the lack of mushroom sources. For this reason, this paper briefly introduces the study on the storage and preservation of Pleurotus ostreatus. Methods: 80% mature Pleurotus ostreatus were harvested, diseases, insects and damaged mushrooms were removed, placed in a clean, cool and ventilated place, and then air-cooled for 1-1.5 days with an exhaust fan.

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

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 occurs when the fruiting body is fully mature.

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.

Treatment of deformity of Pleurotus ostreatus
In the process of Pleurotus ostreatus production, because the management measures are not in place and the environmental conditions are not suitable, deformed mushrooms are often formed. The reasons for the formation of abnormal mushrooms should be found out and effective control measures should be taken in production. 1. The stalk of spherical or flask-shaped Pleurotus ostreatus is spherical or flask-shaped, the surface is uneven or twisted in the shape of waves, the cap can not be formed, only a small point or obvious ice-like stripes. This is caused by virus infection, the application of virus K, virus A, carbendazim spray or smear prevention and treatment. two。 The seed of cauliflower-shaped Pleurotus ostreatus

Occurrence and prevention of deformity of Pleurotus ostreatus
Abnormal mushroom is a common physiological disease in the production of Pleurotus ostreatus, which seriously affects the yield and quality of Pleurotus ostreatus, and even loses its commercial value completely. This disease is mainly caused by improper management, and a few are caused by strain degradation, variation and virus infection. The main types of deformed mushrooms are: 1. The cap of Pleurotus ostreatus is small, the differentiation is poor, and the stalk is longer. The reason was that during the period of primordium formation and differentiation, the mushroom room was anoxic, the light was insufficient, and the temperature was high, which affected the normal differentiation and development of the cap. Prevention and control methods: strengthen ventilation, adjust light and temperature

Control methods of yellow mushroom disease of Pleurotus ostreatus
Prevention and control methods: [1] mushroom facilities should be thoroughly disinfected, detachable supporting materials should be removed, brushed or soaked in bleach solution and dried in the sun, bleach dosage is 1: 150 times water, ground and space should be sprayed with 1:50 times Venus disinfectant solution. [2] the culture material and fermentation material should be thoroughly, and the soil-covering material should be fumigated with formaldehyde (see the control method of Agaricus verrucosporium compiled by our factory) [3] ventilation should be maintained in the mushroom room, and the air relative humidity in the mushroom room should be reduced properly to reduce the concentration of carbon dioxide in the greenhouse.

Occurrence and control of yellow mushroom disease of Pleurotus ostreatus
In recent years, the planting area of Pleurotus ostreatus has been increasing, but due to poor management and poor disease prevention concept, the incidence of yellow mushroom disease is increasing year by year. Some mushrooms shed after a tide of mushrooms, do not produce mushrooms for a long time; some come out of small mushrooms before growing up yellow, and then atrophy death, resulting in a decline in the quality of Pleurotus ostreatus, the yield is difficult to improve. For this reason, the author studied the etiology and comprehensive control techniques of the disease, and the reports are as follows: 1. Symptoms. Yellow mushroom disease is mostly caused by young mushroom cover or small mushroom.

The symptoms of mushroom disease
The yellow spot of Pleurotus ostreatus is a disease caused by Pseudomonas sp. Gram stain showed negative reaction. The disease is a bacterial disease, it widely exists in nature, it has damage to Pleurotus ostreatus, mushroom. Disease: At the initial stage of infection, there are small spotted yellow disease areas on the cap, which expand with the growth of fruiting bodies and infect other fruiting bodies. The color becomes darker and expands to the whole cap. The whole mushroom yellows. The infected mushroom body is water-stained, but it is not sticky and does not rot. Especially, the black mushroom has yellow spots.

Treatment of Water shortage of Culture material in the later stage of Pleurotus ostreatus
The output of the first stubble of Pleurotus ostreatus accounts for about 40% of the total output. Generally, after the second crop of mushrooms is harvested, due to the depletion of water in the culture material, it is rare to produce mushrooms again, the mushroom body is thin, the mushroom meat is loose and dry, and the taste is poor. In order to increase the yield, the following methods can be taken to supplement water and nutrient solution: (1) vertical bag hole irrigation method: the immersion method needs to use a container to hold water, but this method can be used because of the small container or other reasons. Stand the mushroom bag upright on the floor of the mushroom room, pull up the edge of the plastic bag, so as to store water after adding water, and then
