Long-term cultivation of grass-legume mixtures changed the assembly process of the microbial community and increased microbial community stability.

ABSTRACT: Grass-legume mixtures are a common cultivation system on the Qinghai-Tibet Plateau, where the interactions between rhizosphere microorganisms and crops under long-term cultivation are complex and dynamic. Investigating the dynamic changes in microbial community structure and ecological functions is essential. This study investigated the dynamic interactions of rhizosphere microbial communities of Elymus nutans Griseb. cv. Aba and Medicago sativa L. cv. Beilin in a grass-legume mixture at a 1:1 ratio >4 years on the Qinghai-Tibet Plateau. The research focused on their long-term effects on plant productivity, soil health, and microbial functions. The results revealed a decline in grass yield and soil properties in the fourth year (P < .05) and significant year-to-year di
