New high-yield cultivation method for agaricus blazei sowing and earth backing stage management

The invention discloses a new high-yield cultivation method for agaricus blazei sowing and earth backing stage management. The method is characterized by comprising the following steps of: disinfecting and sowing: after dry secondary fermentation of a culture material is finished, distributing the culture material to beds, stabilizing the material temperature below 25 DEG C for sowing, closing mushroom house doors and windows after sowing, beginning ventilation after hyphae are grown to promote downward growth of the hyphae and then closing the mushroom house doors and windows, and spraying 20 to 40 grams of clear water to each bed after the hyphae are grown to the bottom and before earth backing; and culture material hyphae culture and earth backing: uniformly backing the earth with thickness of 3 to 3.5 centimeters, closing the doors and windows after coarse earth backing to promote uniform earth backing of the hyphae, beginning ventilation and refining bacteria for 3 to 5 days after the thick needles of th
