在温度偏高的季节,平菇菌丝和培养料中的微生物代谢旺盛,需氧量较多,而通常的“密实栽培法”不能满足供氧,常有发酵酸气和发酵热产生,轻则延缓菌丝的萌动定植和生长,进而导致污染的增加,重则造成菌种大量死亡。这种现象对平菇的袋栽法尤甚。目前我们常用减少培养料厚度的办法,但效果仍不理想。 In the season with high temperature, the microorganisms in Pleurotus ostreatus and culture medium are metabolized vigorously and have a large amount of oxygen demand. However, the usual “dense cultivation method” can not satisfy the supply of oxygen and often produces fermented acid gas and fermentation heat. Then delay mycelium sprout planting and growth, and then lead to increased pollution, while causing a large number of species died. This phenomenon is particularly pouch planted mushrooms. At present, we often reduce the thickness of the training material approach, but the effect is still not satisfactory.
