【Abstract】Aerobic composting is an important technical approach to the harmless resource utilization of livestock and poultry waste. In actual composting, a certain amount of amendments should be added to promote the effective operation of aerobic composting. At present, the amendments are divided into active and inert ones from the angle of participating in the fermentation process. The effect of active amendments on improving the reactor structure is not obvious, and the carbon-to-nitrogen (C/N) ratio of inert amendments could not be regulated. This study aimed to realize the diverse functions of amendments, such as regulating the chemical properties of compost material and improving the heap structure. The non-sufficiently carbonized woodland wastes (e.g., branches) were used as carbonaceous amendment (CA) to improve the quality of manure aerobic composting. The granule surface of CA material was carbon and the interior was still wood structure. The feedstocks for composting were mainly pig manure and edible fungus residue. Three treatments included the CK (pig manure and edible fungus residue as compost), B1 and B2 [60% (volume ratio) of edible fungus residue in CK was replaced by the CA with a particle size of 1–2 cm and 6–7 cm, respectively]. The composting treatments were in triplicate and lasted for 30 days. The changes in temperature, ammonia volatilization, nitrous oxide emission, pH value and EC value during composting were monitored. Days of heating up to 55 °C for the first time, nitrogen loss rate, C/N change rate, seed germination index and the recovery rate of amendment were selected as the evaluation indexes, and the application effect of CA in composting was analyzed by the fuzzy evaluation method. Compared with the control, CA could obviously promote the rapid increase in heap temperature, reduce the days of heating up to 55 °C for the first time by 4–11 days, and significantly raise compost accumulated temperature. The heating and warming effect of B2 treatment was better than that of B1 treatment. After 30 days of composting, the total ammonia volatilization amounts of three treatments (CK, B1, B2) were 605.41, 374.94, and 303.68 mg/kg, and the accumulated nitrous oxide emissions were 35.80, 49.53, and 74.94 mg/kg, respectively. The nitrogen loss rates of B1 and B2 treatments decreased by 16.13% and 22.81%, respectively. The decrease in nitrogen loss in composting was mainly due to the effective control of NH3 volatilization. CA reduced the EC value of the compost, significantly improved the C/N change rate and the seed germination index. The comprehensive comparison of various indexes and fuzzy evaluation results indicated the composting effect of B2 treatment was better than that of B1 treatment. CA could effectively promote the decomposition of pig manure and improve the quality of composting products, and the suitable particle size of CA for aerobic composting with high temperature was 6–7 cm.
