Two stubble noodles of Pleurotus ostreatus should be peeled.

After two crops of Pleurotus ostreatus harvested, there are often some bad phenomena, such as serious drying hardening, poor air permeability, weak mycelium aging and so on, so as to delay the time of mushroom production, reduce the yield of mushroom body, and even not produce mushroom. If the material surface is scraped off one layer, the hardening problem can be better solved, and there is a good effect of increasing production. The method of peeling the material surface can scrape off a layer of aging bacteria skin completely and thinly for the material surface which is seriously hardened and the bacterial skin is too thick. For the material surface with slight hardening and thick bacterial skin, many small ditches can be drawn vertically and horizontally with iron wire to expose the hyphae. When cultivated in the border bed, you can sweep the bed back and forth with a bamboo broom until the old bacterial skin is scratched and the hyphae inside is exposed. If planted in a bag, the old hyphae at both ends can be scraped off. Peeling has an obvious stimulating effect on primordium differentiation and can promote mycelium growth. Generally, new mushroom buds appear after 7-10 days. But it should be noted that after scraping the material surface, the old fungus skin should be cleaned up so as not to produce miscellaneous bacteria. At the same time, the exposed new material should be pressed flat in order to produce mushrooms neatly. In addition, water should not be sprayed until the growth of the mycelium is restored.
