"Sunshine Mushroom" - Hydrangea, cannot grow without these five environmental conditions
Hydrangea is named for its clusters of entities and its resemblance to a huge hydrangea. The fresh product has the smell of fennel, and the volume shrinks significantly after drying or sun-drying, the color of the petals becomes dark, and the quality is hard and brittle. So what does its growth have to do with it?
Hydrangea is a mesophilic fungus. The mycelium growth temperature ranges from 10 to 28°C, and the optimum temperature is 20 to 23°C. When the temperature is below 10°C and above 30°C, it stops growing and dies after 15 hours. The formation temperature of primordia is 20-22°C, the optimum temperature is 17-19°C, and it is difficult to differentiate when the temperature is lower than 12°C. The growth temperature of the fruit body is 15-22°C, and the slices are normal at 18-20°C, the mushroom body is thick, the yield is high, and the quality is excellent; Growth stops when the temperature is lower than 10°C; when the temperature is higher than 26°C, the fruiting body is easy to wither and die, and it will also be infected with bacterial soft rot, even if the primordium appears, it is easy to die.
The water content of hydrangea culture material should be controlled at 60% to 65%. During the mycelium growth stage, the relative humidity of the indoor air was kept below 70%. The requirement for primordia formation stage is increased to 80% to 85%, and when it exceeds 90%, it is unfavorable for fruiting. The relative humidity of the air should be adjusted to 85% to 90% during the growth period of fruiting bodies. Before picking mushrooms, the humidity should be controlled at 75% to 80%. Low water content is beneficial to prevent diseases, improve quality, and prolong product shelf life.
The mycelial growth stage does not require light. A certain amount of scattered light is needed during the growth and development of the fruiting body to ensure the normal shape and good color of hydrangea. The mushroom growing stage requires 800-1000 lux of light every day, which is the most light-demanding species of all mushrooms, so hydrangea is also known as "sunshine mushroom".
The mycelial growth stage requires less oxygen. The formation of primordia and the development of fruiting bodies require sufficient fresh air, and the carbon dioxide concentration in the mushroom house should be controlled at 600-1000 mg/kg. If it exceeds the standard, it is stunted. During the growth stage, if the ventilation is poor, the indoor oxygen is insufficient, the growth is extremely slow, and high temperature and high humidity will cause rot.
Hydrangea should grow under acidic conditions, the pH value of the compost should be controlled at 3.5-7.0, and the optimum pH value is 4.0-5.0.
