How to Trigger Rapid, Quality Oyster Mushroom Fruiting and Boost Yield?

1. Watering and Top Dressing: In winter, the dry climate and high evaporation rates can hinder mycelium growth. Regular water spraying is crucial to maintain soil moisture, promoting healthy mycelium development and increasing yields. However, avoid excessive moisture that could lead to freezing damage to newly sprouted mycelium during cold spells.
2. Ventilation and Insulation: Proper insulation is essential for maintaining optimal growing conditions for the mycelium. Ensure good ventilation by opening the south-facing windows for 2-3 hours daily. On warm, windless days, both north and south windows can be opened. When temperatures drop drastically, limit ventilation for 1-2 days to keep the room temperature above 6-7°C. Additionally, create holes in the culture material in late December to enhance airflow and expel harmful gases.
3. Soil Loosening and Root Removal: Mid-cycle soil loosening is essential for promoting optimal growth. Gently scrape away the fine soil and loosen the coarse soil. Be careful not to damage the white mycelium, as excessive removal can reduce spring mushroom yields. After removing old roots and dead mushrooms, cover the soil with a fresh layer of fine soil (1-1.5 cm thick). Adjust soil management based on the mycelium's strength and growth conditions in the mushroom house. In houses with strong mycelial growth, larger soil movements can be made, while in weaker environments, minimal disruption is advised. For poorly growing mycelium, avoid soil loosening during winter, and perform it only before mushrooms begin fruiting in spring.

By carefully managing water, ventilation, and soil conditions, you can stimulate rapid and high-quality oyster mushroom fruiting, ultimately boosting yields.
