Key techniques for multiple flushes of white lingzhi mushrooms in spring
White lingzhi mushroom (Pleurotus nebrodensis) is a rare edible fungus developed in recent years, with excellent mushroom quality, good marketability, and high economic and nutritional value, offering broad market prospects. At present, it is mainly cultivated with cottonseed hulls as the main substrate, and developing white lingzhi mushroom cultivation in non-cotton regions presents certain difficulties. Through experiments, the author found that cultivating white lingzhi mushroom using whole corn plants is entirely feasible, and the biological...
Technical measures to promote mushroom emergence from the bags as quickly as possible: Place the bags with fully grown mycelium in the mushroom production site according to the pre-planned fruiting pattern. It is best to use the hole-punching method for opening, that is, punch two round holes 2 cm deep and 0.5-1 cm in diameter symmetrically at the upper-middle part of the bag openings at both ends. Spraying growth regulators: 4-5 days after opening or removing the bag, spray 50-60 mg/L of triacontanol 1-2 times. Control the daytime temperature at 15°C-18°C and the nighttime temperature at 2°C-7°C, with temperature difference stimulation for 10-15 days. Cover the white lingzhi mushroom bags with water-moistened plastic film. Increase the environmental humidity to about 85%, maintain scattered light at 500-800 lux, increase the frequency and duration of ventilation in the mushroom shed, ventilating 2-3 times per day for 0.5-1 hour each time.Cultivation methods for high-quality white lingzhi mushrooms: Use a small knife or bamboo stick to remove excess small mushroom buds, keeping only one well-formed mushroom bud at each fruiting opening of the bag, and try to control the temperature at 6°C-15°C. Under the temperature condition of 6°C-15°C, spray water 1-2 times per day. Do not spray water directly onto the mushroom bodies; spray water onto the ground and into the air, maintaining environmental humidity at about 80%. Ventilate for 1-3 hours per day during the daytime. Direct sunlight does not affect the growth and quality of white lingzhi mushrooms, and the color will not change. When the temperature is above 20°C, direct sunlight should not fall on the mushroom bodies, because strong light will cause the mushroom bodies to turn yellow. The fruiting bodies of white lingzhi mushroom are best harvested at the eight-tenths mature stage, when the mushroom bodies are white in appearance, dense and elastic in texture, with the cap edges curled inward and the gills neatly arranged.
