1. Maintain pure spawn cultures, avoid contaminated spawn and do not place cultures too close together.
2. Limit the number of spawn transfers, minimize mechanical damage and preserve spawn vigor.
3. Use suitable cool storage. Around 4°C helps preserve mycelial vigor in cool-growing mushrooms such as button mushrooms and shiitake; straw mushroom spawn is better kept near 16°C.
4. Avoid repeated transfers on the same medium and do not keep spawn too long. Over-aged spawn loses vigor and is more likely to degenerate.
5. Regularly rejuvenate spawn at a suitable temperature and pH, with sufficient oxygen and contamination-free culture conditions.
6. Carry out annual spore isolation to find superior strains and tissue isolation to preserve their genetic characteristics.
