The period of mycelial growth in the substrate

The most important condition for the rapid growth of the mycelium - the creation of optimal temperature and humidity of the substrate . Duration of mycelial growth in the substrate depends on the method of growing crops . Ridge in the way of cultivation adapted premises . With this method of cultivation, usually the substrate loses a lot of heat through the floor of the room, quicklycools its temperature after planting mycelium after a few days at 18 - 22 ° C, and sometimes lower, so germination substrate mycelium is visually noticeable after 4 - 7 days after planting . Survival rate mycelium checked for 7 - 10 minutes day . To do this in various places over the ridge pieces of mycelium gently lift the substrate . If planted around the mycelium has grown all the pieces for 1 - 3 cm, the survival rate is satisfactory . If these deadlines mycelium is just beginning to form hyphae in some places, the survival rate is considered low . Most often caused by poor survival rate of mycelium its low viability or too lowmoisture content of the substrate . In the first case to re-planting benign mycelium, in the second - a cautious uniform watering substrate with atomized water atomization (preferably through a nozzle sprayer) .

Despite the high humidity, the surface layer of the substrate is generally much dries . This is often the case especially when grown in mushroom adapted premises where providedequipment necessary to maintain the microclimate . In practice, mushroom to protect the substrate surface from drying ridges shelter use newsprint . For shelter suitable paper having sufficient strength and porosity, which retains the necessary level of gas exchange after wetting .

The high concentration of C02 can cause a decrease in the activity of mycelial growthsubstrate only if the ventilation of the cultivation room is absent. Air movement also prevents the occurrence of high temperature zones .

Apparently play a role, and other gaseous products of decomposition of organic compounds and the substrate mycelium metabolism,but their influence on the vegetative growth of the mycelium of the mushroom has been insufficiently studied.
