Abstract Aims The fragile soil structure of coal mine dumps in arid and semi-arid regions presents a major obstacle to ecological restoration. Phytoremediation strategies enhancing porosity are critical, yet Arbuscular Mycorrhizal Fungi (AMF) inoculation efficacy compacted soils combined with mixed planting remains unclear. Methods This study employed two-factor experiment 3D CT scanning assess AMF effects on Amorpha fruticosa root morphology, pore structure, infiltration at northern China open-pit dump. Results Our results demonstrated that both significantly improved development. Notably, the treatment (A-M) yielded most uniform distribution connected pores within cores exhibited highest model complexity correlation analyses. Furthermore, A-M also maximized fractal dimension permeability while reducing tortuosity improving connectivity, attaining peak permeability. With respect led substantial increases morphological characteristics density characteristics. Partial least squares path analysis revealed observed improvements were primarily driven by modifications induced treatments. Conclusions synergistic application effectively optimized architecture enhanced dynamics dump sites, through their stimulatory plant These findings provided strong scientific foundation practical guidance for advancing restoration efforts mining regions.

This research investigated the impact of various mixed sowing combinations on soil nutrients and grass yield within rhizosphere across different seasons. Three varieties leguminous forages—Medicago sativa ‘Gannong No. 3’ (GN3), M. 9’ (GN9), ‘Juneng 7’ (JN7)—as well as three grasses—Leymus chinensis ‘Longmu 1’ (LC), Agropyron mongolicum ‘Mengnong (AC), Bromus inermis ‘Yuanye’ (BI)—were used experimental materials for combinations; monocultures each material served controls. We explored seasonal effects legumes grasses intercropping in Hexi Corridor region China. The results indicated that levels enzyme activity, microbial biomass, treatments followed following sequence: summer > spring autumn. activities biomass were significantly higher than those same growing season (p < 0.05). Specifically, alkaline phosphatase (APA), catalase (CAT), carbon (SMBC), nitrogen (SMBN), phosphorus (SMBP), organic matter (SOM), available (AN), (AP), potassium (AK) GN9+BI group highest among all treatments. hay yields GN3, GN9, JN7 markedly greater their respective Correlation analysis revealed a positive relationship between activities, nutrient levels. comprehensive evaluation GN9 + BI LC are particularly suited widespread adoption Oasis irrigation area.
