ABSTRACT=<p>We investigated the effects of the complex cultivation of <italic>Salvia miltiorrhiza</italic> on microbial communities, secretions, yield, and active ingredients, and the mechanism of action between microbial communities, secretions, and <italic>S. miltiorrhiza</italic> growth and development. Neither maize nor soybean was suitable to grow with <italic>S. miltiorrhiza</italic>, but sesame significantly increased salvinone content, the active ingredient of <italic>S. miltiorrhiza</italic>, and Tanshinone IIA, Tanshinone I, and Cryptotanshinone increased by 27.06%, 22.76%, and 26.41%, respectively, which increased the abundance and number of microbial communities in <italic>S. miltiorrhiza</italic> roots. 16S rRNA results showed that the most abundant bacterial phyla were Proteobacteria and Acidobacteriota, and their number increased with compound planting of sesame and <italic>S. miltiorrhiza</italic>. <italic>Salvia</italic> inter-root secretions affected the microbial community and <italic>Salvia</italic> growth and development, and lipids and lipid-like molecules significantly reduced <italic>Salvia</italic> yield and active ingredients. Overall, different plant secretions can lead to differences in the natural environment and <italic>Salvia</italic> root growth and development, and the composite planting of sesame with <italic>Salvia</italic> can improve inter-root microbial communities, enhance <italic>Salvia</italic> quality, and make fuller use of land resources.</p>
