摘 要 ：采用室内培养和大棚试验相结合,对分离的3种纤维素降解菌在有机废弃物发酵释放CO₂中的作用及其对增加大棚CO₂浓度的效果进行了研究。结果表明,分离获得的三种菌均能明显促进有机废弃物发酵CO₂的释放,其中菌A和菌C的效果优于菌B;3种菌混合接种时效果最佳。在大棚栽培条件下,昼间CO₂浓度大部分时间低于300μL/L,处于亏缺状态;采用棚中不接种直接发酵也可大幅提高大棚的CO₂浓度,但释放的时间只有9.d左右;采用3种菌混合接种的方法棚内全天维持CO₂浓度800μL/L以上的时间可达14.d以上。

Abstract:The impacts of three cellulose-degradation fungi isolated from compost on CO₂ release from fermentation of organic solid wastes and the effects of the fermentation on CO₂ enrichment in greenhouse were studied by carrying out an incubation experiment and a trial in greenhouse.Although all three cellulose-degradation fungi(fungus A,fungus B and fungus C) could accelerate CO₂ release from fermentation of organic wastes,fungus A and fungus C were more efficient comparing to fungus B.The treatment inoculated with the mixture of three fungi showed the best results on CO₂ release.The concentration of CO₂ in greenhouse was lower than 300 μL/L during the majority of daytime,indicating CO₂ is deficient.CO₂ concentration in greenhouse could also largely be improved by fermentation of organic solid wastes without fungus inoculation,but the effective duration only lasts around 9 days.The fastigium and effective duration of CO₂ release could be significantly prolonged by inoculating fermentation medium with the mixture of three fungi,which could maintain CO₂ concentration higher than 800 μL/L during daytime for at least 14 days.
