Detailed Explanation of Key Technical Points for Summer Management of Shiitake Mushrooms
1. Box specifications: Rectangular boxes or baskets measuring 50 x 35 x 10 cm, made by nailing wooden boards together or weaving with bamboo strips, locust twigs, or mountain vines, with nail heads or binding ends facing outward, and plastic film lining the inside. 2. Substrate preparation: Mix 88% hardwood sawdust (or cottonseed hulls or straw), 8% wheat bran or rice bran, 2% cornmeal, 1% sugar, 1% gypsum powder...
The quality of summer management for shiitake mushrooms directly affects yield and profitability. Proper summer management is a key step in shiitake mushroom production. Two methods can be adopted: indoor and outdoor summer management. I. Indoor Spawn Running for Summer Management (1) Minimize the number of shiitake bags indoors and the number of layers of bags. Stack two bags in a tic-tac-toe pattern, no more than 5 layers high, with at least 20 cm between stacks to facilitate ventilation and heat dissipation. (2) Build a shade canopy outside the windows so that sunlight does not shine directly onto the windows or into the room. (3) During hot weather, close doors and windows at 7 AM to prevent outside hot air from entering the room, and open all ventilation openings in the evening for ventilation and air exchange.
II. Outdoor Mushroom Shed Summer Management (1) The mushroom shed should be about 3.5 m high with double-layer shading. The first shading layer should be about 10 cm thick, and the second shading layer should be 1 m above the top of the first shading layer, covered with double-layer shade netting. Both ends of the mushroom shed should be tightly covered with straw curtains, and a 1.5 m long extended shade canopy should be built to help buffer hot air flow. (2) Minimize the number of layers of shiitake bags in the shed. Stack two bags in a tic-tac-toe pattern, no more than 5 layers high, with at least 20 cm between stacks. (3) Keep the temperature inside the mushroom shed below 28°C. During high temperatures, spray water on the exterior of the shed roof. Dig drainage ditches outside the shed and pay attention to drainage. (4) After 7 AM, tightly cover the mushroom shed, and in the evening, open all sides of the shed for ventilation and heat dissipation.
III. Strictly Control Humidity The mushroom shed or indoor space should be kept dry and well-ventilated, with humidity controlled at 50%-60%.
