The symbiotic relationship between cover crops and soil microorganisms is closely linked to nutrient cycling crop growth within agroecosystems. However, how with different root functional traits influence microbial communities, properties, yields has remained understudied. This study assessed the of hairy vetch (HV) rapeseed (RP), along sweet potato yield, enzyme activity under red dryland conditions. High-throughput sequencing was also employed characterize diversity, composition, network structure bacterial fungal communities. According plant economic spectrum theory our research results on traits, HV can be identified as a resource-acquisitive crop, RP treatment resource-conservative crop. Although did not significantly increase rate reached 8.49%. Resource-conservative were associated increased pH, SOC, TP, which enhanced species diversity boosted populations Chloroflexi Alphaproteobacteria. In contrast, promoted proliferation Gammaproteobacteria. Network analysis indicated that facilitated complexity through intensified intra-community competition. Resource-acquisitive stability Collectively, these findings underscore distinct advantages varying in shaping Appropriate rotations effectively regulate communities hold potential enhance yield.
