Summer Management of Pleurotus ostreatus planted in Spring
Pleurotus ostreatus sown in early spring, after entering summer, due to the increase of temperature and humidity, not only inhibit the formation of mushroom buds, but also conducive to the breeding and spread of diseases and insect pests, it is necessary to carry out summer management.
First, choose a place with high terrain and convenient drainage, dig a ditch with a depth of 60 cm to 80 cm and a width of 50 cm, pat the four walls, sprinkle the ditch with lime powder, or spray 800 times the carbendazim solution with lime milk. If there are diseases and insect pests in the culture material, it should be treated first. For those who have been infected with miscellaneous bacteria, scrape off the contaminated area and soak the bag or lump with lime milk or 800-fold carbendazim solution; those harmful to pests can be soaked with 800-fold dichlorvos, and after being dried, they are stacked into a ditch with a height of about 40 centimeters, and then fill the ditch with sandy soil with a moisture content of about 60%. The covering soil should be 20 cm higher than the ground, and then beat to make it loose and tight moderately, and the surface is arched.
Second, in September, the temperature begins to drop, take out the bacterial bag or clot, soak it in rice water for 12 hours, and then put it into the cultivation room for management. To strengthen ventilation and increase the temperature difference between day and night, mushroom buds will appear soon. Then it can be managed according to the routine.

High-yield techniques of Pleurotus ostreatus cultivated in coarse sawdust fermentation material bag
At present, with the development of edible mushroom industry, the demand for raw materials is increasing. The price of fine sawdust in three northeastern provinces has soared in recent years, but coarse sawdust has become waste (such as coarse sawdust leaked from electric sieves on chippers and coarse sawdust crushed by branch shredders). The author uses the local rich coarse sawdust as the main material for fermentation to cultivate Pleurotus ostreatus, which is summarized as follows: 1 the tested strain Pleurotus ostreatus 2026 was introduced from Shijiazhuang High-tech Edible Mushroom Station in Hebei Province to provide mother species. The original seed is corn kernel medium, 99% corn kernels and 1% gypsum. Put the corn kernels

Preventive measures for deformity of Pleurotus ostreatus in winter
1. Blue mushroom: during the growth of the mushroom body, a blue halo occurs on the edge of the mushroom cap, and even the whole mushroom body turns blue-black, which does not fade until harvest. Preventive measures: it is better to use daylight, heating, electric heating and other methods to increase temperature. If firewood and coal are used to increase the temperature, closed heat transfer and smoke exhaust pipes should be installed, and it is not suitable to build the stove directly in the mushroom room. 2. Pleurotus ostreatus: after the occurrence of primordium, the differentiation of cap is not consistent with the rate of development, which is characterized by long stalk, thick and thin bottom, no umbrella and bacteria.
