Double dome Hollow Type LED Operating Lamp is our new design this year, it has the function of perfect green light source new LED green
light source, no radiation, no ultraviolet, no infrared, no radiation and low energy
consumption, little temperature rise and perfect sunlight like shadowless
effect,the surgical lamp use the Unique designed LED optical system with a
higher light utilization rate as much as 2 to 3 times of ordinary ones;

Insulation and ventilation The temperature of the mushroom house in winter is kept above 3°C so that no ice is formed in the room to prevent the frozen mycelium. Before entering the winter, one by one check the four walls of the mushroom house, blocking the air leakage, hanging curtains on doors and windows to prevent cold wind intrusion. Pay attention to ventilation in warm weather and keep the indoor air fresh. Noon opens the south window of the mushroom house for 2 to 3 hours. When the sky is warm and windless and the outdoor temperature is above 8°C, the north and south windows are opened to allow air convection. After noon outdoor temperature is lower than 5°C, ventilation should be suspended.
Spray water and fertilizer to determine the degree of dry and wet soil to determine the number of water sprays to keep the soil moist, to prevent excessive water spray, too much after the bed surface is too wet, to prevent the germination of the mycelium suffered freezing injury. Combined with spray water, the manure water was boiled and filtered and poured at a concentration of 20%.
The loose soil in addition to the old root mushroom house is in good condition and the mycelium grows vigorously. It is possible to scrape the fine dirt from the mushroom bed, loosen the coarse soil, and the loose surface can be larger. Mushroom house conditions and mycelial growth generally do not have to scratch the fine soil on the bed, you can directly loosen the coarse soil. Mushroom house conditions and mycelium growth are poor, winter can not loosing soil, in the coming year 3 to April before the mushrooming, the soil and fine soil will be easily moved once. The white mycelium cannot be peeled off when loose soil, especially the mycelium wrapped around the coarse soil, and the peeling too much affects the yield of the spring mushroom. Remove the old root and dead mushrooms from the mushroom bed, and re-pave the coarse soil and fine soil. When the hyphae germinate 1 week after the last loose soil, a layer of 2 to 3 cm thick soil is placed on the mushroom bed. Spray water and apply fertilizer 2 to 3 times before covering soil to supply enough water and nutrients to promote the germination and growth of mycelium.
Winter tube good mushroom bed spring mushroom yield
Autumn mushrooms no longer heat up after the harvest to produce winter mushrooms, mushroom bed into the winter management stage. The quality of the winter management of mushroom beds has a great influence on the yield of spring mushrooms in the coming year.
