Abstract The effects of bamboo biochar (BB) variables on gaseous emissions, maturity and microbial dynamics during composting of sheep manure were investigated. The experiments were conducted with six different ratio of BB (0%, 2%, 4%, 6%, 8% and 10% dry weight based) and 0% is compiled as control. The results showed that 10%BB provided rapid mineralization and less time duration of compost maturity. 10% BB has the excellent impact on greenhouse gas (GHG) emission reduction and nutrients conservation (nitrogen and carbon losses were 13.40 g/kg and 124.42 g/kg) as compared to other treatments. Control was significantly different from other treatments in terms of GHG emission and nitrogen loss and had the lowest germination index after 42 days composting. BB addition were the main factors influencing GHG emission and improve the bacterial abundance. There is a significant correlation among the analyzed physicochemical factors, gaseous emission and bacterial phylum is used 8–10% BB for SM composting. Higher percentages of BB not only reduced CH4 and N2O emissions but also showed significant influence on CO2 and NH3 losses as well as improve the end product quality.

生物炭对羊粪堆肥过程中排放、成熟度和细菌动力学的影响

摘要 研究了竹生物炭 (BB) 变量对羊粪堆肥过程中气体排放、成熟度和微生物动力学的影响。实验以六种不同比例的 BB（基于干重的 0%、2%、4%、6%、8% 和 10%）进行，0% 编译为对照。结果表明，10%BB 提供快速矿化和较短的堆肥成熟持续时间。与其他处理相比，10% BB 对温室气体 (GHG) 减排和养分保护（氮和碳损失分别为 13.40 g/kg 和 124.42 g/kg）具有极好的影响。对照在温室气体排放和氮损失方面与其他处理显着不同，并且在堆肥 42 天后发芽指数最低。添加BB是影响温室气体排放和提高细菌丰度的主要因素。分析的物理化学因素、气体排放和细菌门之间存在显着相关性，使用 8-10% BB 进行 SM 堆肥。较高百分比的 BB 不仅减少了 CH4 和 N2O 的排放，而且还对 CO2 和 NH3 的损失产生了显着影响，并提高了最终产品的质量。
