30 days aerobic composting was conducted by home-made forced ventilation static pile composting reactor using rawmaterials such as pig manure as compostsubstrate，and apple residue with the proportion of0%，5%，10%，20% respectivelyand 1% citricacid.The effects of apple residue on swine feces composting were studied according nutrients change during thecomposting process，in order to provide theoretical support for using swine feces as organic fertilizer and achieve sustainableutilization of agriculturalresources.The results showed that the composts of all treatments had met the requirement of theinnocuity and maturity by the Fecal Harmless HealthStandard.The total P and K contents showed increasinggradually，butadding 20% of apple residue decreased the accumulation of Pcontent.The fruit acid in the apple residue reduced the pH of the compost and reduced the conversion of NH4+-N to ammonia gas，thereby reduced nitrogen loss then maintained the nitrogenretentioneffect.The addition of 10% apple residue had the highest total nitrogen content and the best nitrogen retentioneffect， 5% apple residue treatment had the greatest impact on the accumulation of NH4+-N.As the swine feces aerobic compostingconditioner，apple pomace can improve the composting effect and realize the sustainable development of agriculturalresources.
