How to manage the mycelial growth stage of the shaggy mane mushroom
Before October, temperatures are relatively high. At this time, the spawn bags are placed on the ground in 1 layer, with a 3 cm gap between bags. For incubation, besides the mushroom house, private houses or shaded areas under trees can also be used. After October, the weather is changeable, so outdoor incubation is required. Choose a wind-sheltered, sunny open area, level the ground, and begin arranging the spawn bags. In autumn, arrange 3 layers of spawn bags, ...
The mycelial growth temperature of the shaggy mane mushroom is 5°C to 35°C, with an optimum temperature of 22°C to 28°C. Within 3 days after inoculation, focus on moisture retention and temperature control. Keep the temperature at 25°C to 28°C, do not ventilate, and do not move the spawn bags or uncover the plastic film. When growing in bags, keep the indoor air humidity at about 70%; for bed cultivation, keep the air humidity at 80%, and uncover the film for ventilation 3 days after inoculation. When growing in bags, turn the pile about every 7 days to prevent contamination. During the mid-incubation period, keep the room temperature at 20°C to 25°C, pay attention to ventilation, and prevent the mycelium from overheating. Under normal conditions, the spawn bags are fully colonized by mycelium after 30 to 35 days.
Bag removal and casing soil. After the mycelium of the shaggy mane mushroom has fully grown, casing soil is required for normal fruiting. Remove the bags from the fully colonized spawn bags and arrange them on the beds in the mushroom house (mushroom shed), with the substrate logs 2 to 3 cm apart, and fill the gaps with soil. After all the substrate logs are arranged, cover them with 3 to 5 cm of soil. The casing soil should be selected from vegetable garden, orchard, wheat field, or paddy field soil, or a homemade mixed soil can be used. Before use, the casing soil must be disinfected. The best disinfection method is heating with steam, maintaining it at 60°C to 65°C for 3 to 4 hours, or at 70°C to 75°C for 1 to 2 hours.
After casing, spray once with a heavy watering to adjust moisture, and cover with plastic film to keep warm. After 3 days, remove the film and ventilate 1 to 2 times a day. At the same time, spray with a fine mist to keep the bed surface moist. After 10 to 20 days, the mycelium climbs onto the casing soil surface and enters the fruiting stage management.
