Can wine dregs grow Pleurotus ostreatus?
It is possible to use wine dregs instead of wheat bran as auxiliary materials for the production of Pleurotus ostreatus, the general dosage is about 20%, and the other 70-80% can be used with cottonseed hulls or sawdust. As the wine residue is relatively sour, it should be mixed with some lime before use to reduce the PH to 6-6.5.

Fungus membrane--the enemy of high yield of Pleurotus ostreatus
Covering soil culture is an important measure to obtain high yield of Pleurotus ostreatus. However, before fruiting or after harvesting the first crop of mushrooms, a water-tight and air-tight bacterial membrane is often formed on the surface of the covering soil by vigorous aerial hyphae, which affects fruiting. This kind of bacterial film will consume a lot of nutrients, resulting in yield reduction of Pleurotus ostreatus, which must be prevented in production. The reasons for the formation of bacterial film are as follows: firstly, when the bag material of bag cultivation is not sufficient, it will be covered with soil, resulting in the second vegetative growth of mycelium on the ground surface and the formation of bacterial film; secondly, the formula of cultivation material is unreasonable, and the nitrogen content is blocked.

Processing method of oyster mushroom sauce
Select 7-8 mature mushroom, remove mushroom feet, wash. in that proportion of 100 kilogram of fresh mushrooms and 5 kilogram of salt, the fresh mushrooms are put into a jar for pickling for 3 days, the brine is removed, 10 kilogram of salt is added into the jar for pickling, 7-10 days are added into the jar, the brine is removed, and proper amount of salt is added for pickling for the third time. At this time, it has reached 22 degrees Be brine, which becomes salt blank and can be preserved for a long time. soak each 100 kg of salt blank in 400 kg of clear water for 8 hour, taking out, draining, soak in clear sweet sauce for 8 hours, taking out, draining
