Scraping the mushroom bed surface of oyster mushrooms can increase mushroom weight

After two harvests of oyster mushrooms, the bed surface often becomes severely dry and compacted, with poor air and water permeability, and the mycelium becomes senescent and weak, which delays the fruiting time, reduces mushroom yield, and may even result in no mushrooms at all. Scraping the bed surface can effectively solve this problem and produce a very good yield increase.

The method for scraping the bed surface is: for a severely compacted bed surface with an overly thick mycelial skin, scrape off a thin layer of the aged mycelial skin over the entire surface. For a slightly compacted bed surface with a relatively thick mycelial skin, use a wire to scratch many small crisscrossing grooves until the mycelium is exposed. For ridge-bed cultivation, use a bamboo broom to sweep back and forth over the bed surface until the old mycelial skin is broken and the mycelium inside is exposed. For bag cultivation, scrape off the old mycelium at both ends. Scraping the mycelium has a clear stimulating effect on primordium differentiation and can promote mycelial growth; generally, new mushroom buds appear after 7-10 days.

However, it should be noted that after scraping the bed surface, the scraped-off old mycelial skin must be removed completely to avoid contamination by weed molds. At the same time, the exposed new bed surface should be leveled flat to promote uniform fruiting. In addition, watering should wait until the mycelium has resumed growth.
