Grass residue decomposition is crucial for nutrient cycling in agro-ecosystems, enhancing utilization efficiency and supporting sustainable crop management. While grass mulching has been widely studied improving orchard soil fertility, the role of microbial communities decomposing different plant organs remains unclear. Before decomposition, aboveground belowground parts were harvested placed separate litterbags, which later used evaluating rate chemical characteristics shoots roots 40 days (at 10 intervals). The changes microenvironment, community measured after 0, 1 3 months, alongside analysis key taxa under residues treatments. remaining mass root litter treatment was significantly higher than that other treatments by 72.97%, 17.53% during 1–10 30–40 days, respectively. During 40-days period, release potassium (K) from reached 58.61%, lignin recorded at 56.94%, whereas carbon (C), nitrogen (N), phosphorus (P) remained relatively stable.

Litter rates positively influencing fertility keystone decomposers, while its microenvironment affects rates. recalcitrance, composition plays a regulating structure thereby maintaining ecosystem functionality.
