Detailed Explanation of Key Technical Points for Inducing Bud Formation and Shelf Fruiting of Shiitake Mushrooms

After the substrate bags change color, they enter the fruiting stage. The key management points during the bud induction period are: manually increase the temperature difference and the wet-dry difference, keep the temperature at 15-20°C and the humidity at 85%-90%, combine with ventilation, and apply temperature difference stimulation; after 3-5 days, mushroom buds will appear in large numbers. In winter, bud induction focuses mainly on heat preservation. The methods are: (1) Induce buds on indoor shelves: arrange the substrate bags neatly on the shelves with 2 cm between bags, place 1-2 stoves in the room, keep the temperature at 15-20°C, ventilate 3 times a day for about 1 hour each time, remove coal gas, and ensure fresh air. (2) Induce buds in a shed: use sunlight during the day to keep the temperature inside the bags at 15-20°C, and at night use a heating flue or coal stove to raise the temperature to 8-15°C; spray water directly 3 times a day, and keep the humidity in the shed at about 90%. (3) Induce buds by stacking: after taking the substrate bags out of the water, stack them in a "" shape 6-8 layers high, cover with plastic film, then cover the outside with protective material, and ventilate 3 times a day. (4) Induce buds by arranging them individually upright: place the substrate bags upright on the ground in a staggered pattern, cover with plastic film during the day, add straw mats at night for insulation, and ventilate 3 times a day for 30 minutes each time; ventilate at noon together with spraying water to increase humidity.
