Straw reinforcement improves the mechanical properties of soil matrices by uniformly incorporating dispersed straw materials, demonstrating advantages in strength enhancement, toughness improvement, and deformation control. This study aims to compare effects different types on clarify optimal method for straw-based stabilization. For wheat straw-reinforced using processing methods (straw segment, powder, ash) mass contents, basic geotechnical each mixture were first determined. Triaxial tests then performed under varying confining pressures compaction conditions assess modulus characteristics reinforced specimens, microstructural fiber-reinforced investigated scanning electron microscopy (SEM) analysis. The experimental results indicated that ductility soils increased significantly with addition straw. performance occurred at 0.3% content. elastic 85%, 64%, 57% 50 kPa, 100 200 respectively. At segments provided highest increase 57%, while ash achieved greatest improvement 97%. Furthermore, considering both cost efficiency, a degree 95% is recommended engineering applications. Based microscopy, it was observed distribution within exhibit distinct patterns. provide data support efficient utilization materials
