Study on the effect of compound cultivation on the growth feature and active ingredients content of .

We investigated the effects of the complex cultivation of on microbial communities, secretions, yield, and active ingredients, and the mechanism of action between microbial communities, secretions, and growth and development. Neither maize nor soybean was suitable to grow with , but sesame significantly increased salvinone content, the active ingredient of , 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 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 . inter-root secretions affected the microbial community and growth and development, and lipids and lipid-like molecules significantly reduced yield and active ingredients. Overall, different plant secretions can lead to differences in the natural environment and root growth and development, and the composite planting of sesame with can improve inter-root microbial communities, enhance quality, and make fuller use of land resources.
