Elm mushrooms have strong growth force, fast mushroom production, short growth period, high yield, can be cultivated in both wood and bag, mycelium is strong and can grow and develop on sawdust medium of elm, poplar, birch, linden, ash, acacia and other broadleaf trees, and also on sawdust medium of red pine, sandy pine, fish scale pine, fir, cypress and other sawdust medium, but the yield is very low. It can also grow and develop on cottonseed hulls, waste cotton, corn cobs, peanut hulls, bean hulls, wheat straw, rice straw, tea dregs, and waste cultures of planted straw mushrooms and mushrooms. Among them, the yield of Elm mushrooms cultivated on cottonseed husk, waste cotton and corn cobs is higher. Mycelium growth and development temperature range of 7 to 32 ℃, the optimal growth temperature of 23 to 27 ℃, 45 ℃ or more after 2 hours of mycelium will die, but can withstand -38 ℃ low temperature. Substrate formation temperature of 10 ~ 28 ℃, the optimal growth temperature of 15 ~ 25 ℃. pH5 ~ 7 can grow to pH5 ~ 6.5 is most suitable.
