Abstract：Apple pomace is often disposed of in a crude manner,resulting in a low level of resource utilization.Therefore,an aerobic composting experiment was conducted using apple pomace as the main material,supplemented with beef cattle manure and sheep manure at different ratios(T1:60％apple pomace+40％beef cattle manure,T2:50％apple pomace+50％sheep manure,T3:55％apple pomace+22.5％beef cattle manure+22.5％sheep manure),to investigate the effects on compost maturity and fertilizer efficiency.The results showed that all treatments met the harmlessness standards(temperature ≥55℃,Ascaris egg mortality rate ≥95％).Among them,treatment T2 exhibited the highest organic matter content(54.34％)and the highest total nutrient content(6.90％),making it the optimal raw material combination.The pH,electrical conductivity,nutrient contents,and humus components of all treatments complied with the national standard for organic fertilizers(NY/T 525-2021).Comprehensive maturity evaluation indicated that co-composting apple pomace with cattle and sheep manure could achieve efficient resource utilization and reduce environmental pollution.This outcome enables effective utilization of apple by-products and alleviates resource wastage.
