This study reveals how microbial diversity relates to soil properties in Auricularia heimuer residue–chicken manure composting, presenting sustainable waste recycling solutions. These microbial-straw strategies are adaptable various agroecological regions, offering flexible residue valorization approaches for local conditions, crops, and resources. examined the effects of composting chicken at three ratios (6:4, 7:3, 8:2) on properties, lignocellulose content, enzyme activity, diversity, maize growth. The compost was mixed into potting different proportions (0:10 10:0). During temperature remained above 50 °C more than 14 days, meeting safety sanitation requirements. process resulted a pH range 7–8, stable moisture content 60%, color change from brown gray-brown, elimination unpleasant odors, formation loose aggregates. Lignocellulose steadily decreased, while lignocellulosic activity actinomycete abundance increased, indicating suitability field application. Compared with control (CK), total nitrogen, phosphorus, potassium increased by 57.81–77.91%, 4.5–19.28%, 301.09–577.2%, respectively.
