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.
