摘　　要：针对闲置贮梨冷库进行金针菇生产易造成库内CO2过度积累而影响金针菇商品性能问题,采用观测和模拟试验,对贮梨冷库生产金针菇时的CO2浓度变化及排除方法进行了研究。结果表明:金针菇菌丝体和子实体发育过程中不断产生CO2,且所产生的CO2浓度随时间延长而增高;在冷库近底层增加新风口,与库门构成平抽气流的改建设计,能有效提高CO2的排除效果,机械通风并辅以化学吸收剂Ca(OH)2,可有效保障库内CO2浓度与金针菇子实体生长发育的不同阶段相适应。The mycelium and sporophore of Flamulina jelutipes could result in higher CO2 concentration accumulated excessively to be incapable of removing CO2 out immediately when using old ventilation in the pear refrigerated warehouse produced Flamulina jelutipes. This research proposed a set of ventilative design for rebuilding refrigerated warehouse which could remove CO2 out efficiency. Additional, the methods of mechanical ventilating with Ca（OH） 2 for chemical absorption have been adopted for growing of Flamulina jelutipes at different developing period to ensure them growing in the appropriate condition.
