Pleurotus ostreatus variety-- Brown top 81
In the later stage of the emergence of this variety, it is not easy to form bacterial film on the substrate surface and produce mushrooms smoothly; the buds are sparse, the mushroom rate is high, and large clumps of mushrooms are easy to form; once the mushroom buds appear, they are black tumors, which are mainly due to the increase of the cap to maturity, and the stalks are not obviously elongated; the mushrooms are enlarged, sturdy and horizontally extended, and the cover of the young fruit body is black, dark brown or brown after maturity. Mushrooms can also be grown normally in civil air defense tunnels with poor ventilation. The fungal stalk is short or basically sessile, and the bacterial cover accounts for a large proportion, so it is very suitable for processing canned products.

Analysis and Countermeasures of Meteorological Diseases of Pleurotus ostreatus
The cultivation practice of Pleurotus ostreatus for many years has proved that the abnormal sharp rise or sudden drop of temperature in spring can cause the same meteorological disease of Pleurotus ostreatus in the same climatic area. if it is poorly managed, a large number of wilting and death will occur in the fruiting body of Pleurotus ostreatus within 1-7 days. heavy losses. Therefore, it is of great practical significance to study the meteorological diseases of edible fungi, make use of the weather forecast results and formulate effective defense measures to reduce the loss of edible fungi and improve the economic benefits of growing mushrooms. 1 typical case and analysis 1.1 typical case 1:1

Pleurotus ostreatus variety-- Pleurotus ostreatus
The early-maturing Pleurotus ostreatus introduced from Japan has high yield and good quality, with a yield of 11.93-14.07 kg / m ~ 2 and a biological efficiency of 95.4%. The optimum humidity for mycelium growth was 24-28 ℃. The hyphae are white and short velvety. The fruiting body formation temperature is 5: 25 ℃, there is no over-summer period, and the optimum temperature is 18-22 ℃, which belongs to the medium temperature type of Pleurotus ostreatus. The fruiting body is clustered, imbricate, the cap is shell-shaped, the edge is smooth, grayish black when young and brown when mature. The fungus is white and delicate. The stalk is white and lateral. The spores are pink.
