Abstract: In order to provide the basis to increase the productivity of Agaricus bisporus, the author made yield graph through the observation and recording of the condition change in mushroom house in the factory production. The author conducted tunnel fermentation with the materials of wheat straw and manure, mushroom house temperature was adjusted by air-condition, and the environment factors and yield of the 4 rooms were measured in one production cycle. The results showed that the overall environment condition met the needs of mushroom growth. From after sowing period to cooling period, the room temperature was maintained at 16-21℃, the differences of material temperature among layers were significant, and material temperature of the upper layer was higher than that of the lower layer. The room temperature was maintained at 16-18℃ and the material temperature was at 18-20℃ in the harvest period. The material temperature of different layers had no significant difference. The humidity and CO₂ were maintained at a good level and the sporocarp grew normally in the harvest period. Under the same condition of cultivation and management, the yield of A15 was higher than that of 192, and the yields of mushroom houses with 600 m² cultivation area all reached more than 12 t. The highest yield was 14.6 t, which equaled to 21-24.3 kg/m².
