This study investigated the impact of mature compost input on compost quality, greenhouse gases (GHGs, i.e. methane and nitrous oxide) and ammonia emissions during chicken manure and rice husk chicken manure co-composting. The experiment used different volumes of mature compost: 10% (T1), 20% (T2), and 30% (T3) to replace rice husk chicken manure. Results showed that mature compost enhanced compost maturity by promoting the activities of Bacillus, Caldicoprobacter, Thermobifida, Pseudogracilibacillus, Brachybacterium, and Sinibacillus. Compared to CK, T1, T2, and T3 reduced NH emission by 32.07%, 33.64%, and 56.12%, and mitigated 14.97%, 16.57%, and 26.18% of total nitrogen loss, respectively. Additionally, T2 and T3 reduced CH emission by 40.98% and 62.24%, respectively. The NO emissions were positive correlation with Lactobacillus, Pseudogracilibacillus and ammonium nitrogen (p < 0.05), while T2 reducing total greenhouse effects. Therefore, replacing rice husk chicken manure with 20% mature compost is an efficient and promising approach for composting.
本研究探讨了成熟堆肥投入对鸡粪和稻壳鸡粪共堆肥过程中堆肥质量、温室气体（即甲烷和氧化亚氮）和氨排放的影响。该实验使用了不同体积的成熟堆肥：10%（T1）、20%（T2）和 30%（T3）来替代稻壳鸡粪。结果表明，成熟堆肥通过促进芽孢杆菌、喜温硫杆菌、嗜热纤维单胞菌、短小芽孢杆菌、短芽孢杆菌和辛纳氏芽孢杆菌的活性，促进了堆肥的成熟。与 CK 相比，T1、T2 和 T3 分别减少了 32.07%、33.64%和 56.12%的 NH 排放，分别减少了 14.97%、16.57%和 26.18%的总氮损失。此外，T2 和 T3 分别减少了 40.98%和 62.24%的 CH 排放。NO 排放与乳杆菌、短小芽孢杆菌和铵态氮呈正相关（p<0.05），而 T2 降低了总温室效应。因此，用 20%的成熟堆肥替代稻壳鸡粪是一种高效且有前景的堆肥方法。
