The mycelium of Pleurotus ostreatus appears "alopecia spot".
Some of the long hyphae in the culture material, some do not grow hyphae, or long hyphae on the surface but not in the material, which is called "alopecia areata". The main causes are too much water or uneven mixing, insufficient moisture regulation, too large, too thick, too tight, and poor ventilation or overtemperature after sowing.
Prevention and control methods: add an appropriate amount of water, mix the material evenly, the block should not be too big, too tight and too thick, and often check the material temperature to avoid overheating of the culture material itself. due to overtemperature, "spot alopecia" should be replanted in time, and ventilation should be increased due to moisture.

What about slow growth of mushroom hyphae?
In the process of cultivation and management, it is necessary to master the biological characteristics of different varieties, understand the requirements of nutrition, water, temperature, light, pH and other environments during the growth and development stage of mycelium, and after inoculation,(10%-15% inoculation), the mycelium can be observed to extend outward in 2 - 3 days in the culture room, 3 - 5 cm in 7 - 10 days, full bag in 20 - 30 days, and fruiting in 35 - 45 days. If this standard is not met, the reasons are: (1) the raw materials are stored for too long, acidic,

Causes and Countermeasures of delayed emergence of Pleurotus ostreatus mycelium after eating food
In the cultivation of Pleurotus ostreatus, it is sometimes encountered that the mycelium of some bacterial bags or bricks grow well, but do not produce mushrooms for a long time after eating completely. The main reasons and remedies are as follows: 1. The varieties of Pleurotus ostreatus do not match with the selection of season. The temperature gap between the temperature type of strain and that of cultivation is too large, which can also be said to be the improper choice of sowing time. If the medium and low temperature type of Pleurotus ostreatus is sown at the turn of spring and summer, it is difficult to produce mushrooms in the high temperature season after the mycelium is full. Remedy: dig grooves in the shade to cover the soil for the summer, and remove it when the autumn is cool.
