Hanging cultivation techniques of Lentinus edodes in winter

The hanging cultivation technology of Lentinus edodes can make full use of the effective area of mushroom shed and mushroom house, and the yellow water secreted by mycelium can drop naturally, so it is convenient to spray, manage and harvest. When the air temperature is low, boiler steam can be used to heat up, so it is easy to adjust the temperature and humidity, which is conducive to the production of Lentinus edodes in winter. The culture material of Lentinus edodes inoculated with Lentinus edodes was prepared according to the conventional formula of bag cultivation. Choose polypropylene or polyethylene plastic bags with specifications of 17 × 33 cm, 0.4 kg of dry material (about 1 kg of wet material) and moderate tightness. Sterilized under normal pressure, cooled to less than 30 ℃, inoculated according to aseptic operation, put in the culture room or mushroom shed code bag (code 3-5 bags) to sterilize. The sterilized culture material can also be loaded into a pressing box with a specification of 66 × 33 × 5 cm for block inoculation culture. After 50-65 days of culture, the mycelium can be full of mycelium. At this time to strengthen ventilation, to promote the bacteria tube, fungus mass color change, in order to facilitate the suspension of mushrooms. Hanging requires the mushroom house or shed to be fumigated with formaldehyde, then sprinkle some lime powder or spray medicine on the floor and walls to prevent diseases and insect pests, and finally spread a layer of fine sand on the ground. Then take the 1.67m long nylon rope and fold it into a 0.835 m long double strand rope. Tie four dead knots evenly on the rope, and then tie one end of the two double ropes to the cross beam in the mushroom room or shed to replace the culture rack to hang the mushroom tube or mushroom block to produce mushrooms. When the mushroom block or tube changes color into a reddish brown or light brown bacterial film, the mushroom tube or mushroom block is carefully hung from top to bottom into a double-strand nylon rope dead-knot space, with a layer distance of 10-15 cm, and a thin film is placed around the top and edge of the suspended Lentinus edodes tube or mushroom block for heat preservation and moisturizing, and the film is clamped together with a clamp. The temperature in the mushroom house or shed is 20 ℃ ~ 25 ℃, and the relative humidity is 90% and 95%. Under normal circumstances, budding begins after 15-20 days of suspension. It usually takes 10 to 15 days from budding to maturity. After harvest, it should be managed according to the routine, so that it can continue to produce mushrooms normally.
