The management of Grifola frondosa before fruiting is mainly the management before discharging bacteria and fruiting. Most of the high-yield varieties of Grifola frondosa are large in plant type per plant, and more culture materials are needed for mushroom production. Because a single mushroom stick is small, it needs multiple mushroom sticks to be connected into a whole to achieve high yield and high efficiency, so it is necessary to carry out mushroom management before fruiting. After the hyphae are full of bags, take off the plastic bags, arrange the fungus sticks neatly in a single layer in the pre-dug bed or on the mushroom rack (bed), fill the gaps and the surrounding of the fungus sticks, and cover the surface with a soil layer of 1 ~ 2 cm. This is a form of mulching cultivation, and discharging bacteria is a key step in Grifola frondosa production. The conversion efficiency of raw materials into fresh products can reach 100% ~ 120%, which is 30% ~ 50% higher than that of direct fruiting.
