How to safely overwinter shiitake mushrooms through summer? These management points must be mastered

The quality of summer management for shiitake mushrooms directly affects yield and profitability. Doing a good job of summer management is a key step in shiitake mushroom production, and two methods can be used: indoor and outdoor.

I. Indoor spawn running for summer survival

(1) Minimize the number of shiitake bags indoors and the number of bag layers. Stack two bags in a cross pattern, with no more than 5 layers at most, and keep the spacing between stacks at more than 20 cm to facilitate ventilation and heat dissipation. (2) Build a shade canopy outside the window so that sunlight does not shine directly onto the window or indoors. (3) In hot weather, close doors and windows at 7 a.m. to prevent outside hot air from entering indoors, and in the evening open all ventilation openings for ventilation and air exchange.

II. Outdoor mushroom shed for summer survival

(1) The shed is required to be about 3.5 m high with double-layer shading. The first shading layer should be about 10 cm thick, and the second shading canopy should be 1 m away from the top of the first shading canopy, using double-layer shade nets or reed curtains. Cover both ends of the shed tightly with straw curtains, and build a 1.5 m long extended shading canopy to help buffer hot air. (2) Minimize the number of mushroom bag layers in the shed. Stack two bags in a cross pattern, with a height below 5 layers, and keep the spacing between stacks at more than 20 cm. (3) Strictly control the temperature inside the shed below 28°C. In high temperatures, spray water on the outside top of the shed. Dig drainage ditches outside the shed and pay attention to drainage. (4) After 7 a.m., shade the shed tightly, and in the evening open the surroundings 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, and humidity should be controlled at 50%-60%.
