What are the key points of the management of Pleurotus ostreatus planted in autumn?
When Pleurotus ostreatus is planted in autumn, the temperature changes from high to low, the climate is humid and rainy, the miscellaneous bacteria are more active and dense, and the mycelium growth stage is not easy to manage. Therefore, to ensure success, the following technical measures can be taken:
The main results are as follows: (1) thorough sterilization: the main cultivation methods are clinker cultivation and stacking fermentation material cultivation. Cultivation with plastic bags is easy to check and manage, and the success rate and bioconversion rate are very high.
(2) select good varieties: the temperature decreases gradually in autumn, do not select high and medium temperature varieties, in case it is difficult to manage or deformed mushrooms due to low temperature in the later stage. Wide-temperature or low-temperature varieties should be selected.
(3) increase the sowing rate: autumn is hot and humid, miscellaneous bacteria are active, and the sowing amount of bacteria must be larger than that in winter, which should be controlled at about 20%, so that the hyphae of Pleurotus ostreatus can grow all over the material surface as soon as possible, so as to inhibit the infection and growth of miscellaneous bacteria.
(4) prevent "burning bacteria": code the inoculated bacteria bag into the shape of "well", generally 2-3 stories high, the bacteria can not be pressed. It is necessary to strengthen ventilation and often check the temperature of the material to prevent "burning bacteria" caused by bacteria contaminated by high temperature.

Key points of Technical Management of Pleurotus ostreatus cultivated in Autumn
Pleurotus ostreatus after sowing to before the emergence of mushrooms is called the fungus stage. The degree of technical management in this period is the key period to determine whether the mycelium of Pleurotus ostreatus can grow and develop normally in the culture material and whether it can obtain high quality and high yield in the future. Therefore, it is very important to strengthen the management of Pleurotus ostreatus. In the investigation, the author found that many Pleurotus ostreatus producers think that Pleurotus ostreatus is easy to grow and extensive management, and after sowing, they often ignore the scientific management of the fungus period and take it lightly, which leads to the reduction of Pleurotus ostreatus production and failure of harvest.

The strain of Pleurotus ostreatus should be selected correctly in autumn
The quality of strain is the key to the high yield of Pleurotus ostreatus. The high-quality secondary and tertiary strains of Pleurotus ostreatus should have the following characteristics: the hyphae are dense, white, uniform and stout, fluffy, wall-climbing, a small amount of coral-shaped buds appear on the surface of the culture medium, and the appropriate age is 20-25 days. The cross-section mycelium of the strain is obvious and has obvious mushroom flavor. If a large number of fruiting body primordia appear on the surface of the culture medium, it means that the strain has matured and should be used as soon as possible. Before introduction, we must find out the temperature type of the strain, and then according to
