1. Culture material treatment: choose fresh cottonseed hulls or corn cobs as raw materials. Before mixing the material, it should be exposed to the sun for 2-3 days, or ultraviolet light should be used to kill some of the contaminating microorganisms in the culture material. During fermentation, strictly follow the fermentation process to ensure it is thorough, even and complete. Products such as warming fermentation agents, Lixin Junwang or Kemei Wang can be added to improve resistance to contaminating microorganisms. 2. Management during the spawn-running period: when cultivating large bags for fruiting, they should be placed in a cool, ventilated and clean location. Try not to cultivate them inside the mushroom house (shed), to avoid the growth of large amounts of contaminating microorganisms during the mycelial cultivation process, which can lead

2. Management during the spawn-running period: when cultivating large bags for fruiting, they should be placed in a cool, ventilated and clean location. Try not to cultivate them inside the mushroom house (shed), to avoid the growth of large amounts of contaminating microorganisms during the mycelial cultivation process, which would contaminate the fruiting site, and to avoid high-temperature damage to the spawn, which reduces the vitality of the mycelium.

3. Mushroom house treatment: before use, it is best to leave the shed empty and exposed to the sun for a period, or rotate with other crops. 2-3 days before the fruiting bags are brought into the mushroom house (shed), the old mushroom shed should be thoroughly cleaned and disinfected while empty. Fumigants, sulfur or formaldehyde can be used.

4. Soil disinfection: use virgin soil from fields or vegetable gardens, keep it away from domestic waste and livestock and poultry farms, and disinfect and pile-ferment the selected casing soil.
