The novel edible mushroom cultivation frame comprises a supporting table, the supporting table comprises supporting legs,a water storage tank is arranged on the supporting table, a water inlet pipe communicated with an inner cavity of the water storage tank is arranged at the upper end of the left side wall of the water storage tank, and a water level pipe communicated with the inner cavity of the water storage tank is arranged at the lower end of the left side wall of the water storage tank; a backflow pipe communicated with an inner cavity of the water storage tank is arranged at the upper end of the right side wall of the water storage tank, a backflow sleeve communicated with the backflow pipe is arranged at the top end of the backflow pipe, a water suction pump is arranged in the center of the top end face of the water storage tank, the output end of the water suction pump is connected with a guide pipe, and a spraying head is arranged at the free end of the guide pipe. A plurality of layers of water storage tanks are arranged over the supporting table through supporting columns. The fungus bag humidifying device is reasonable in structural design, not only can humidify fungus bags on the cultivation frame, but also can collect water dripped from the humidified fungus bags, and is high in practicability and excellent in market popularization value.
