“…Li et al (2022) found that Acidobacteriota and Proteobacteria were the dominant phyla in the maize intercropping system, and Proteobacteria relative abundance in the intercropped maize root soil increased significantly, primarily due to interspecific root interactions resulting in differences in bacterial community structure during intercropping. Meanwhile, Wang et al (2019) showed that crop rotation and crop set could improve soil quality and inter-root bacterial diversity to some extent, and Symbiodinium relative abundance was higher in crop rotation and crop set than in continuous crop. In our experiment, Proteobacteria (26.41%-44.04%) and Acidobacteriota (8.37%-26.88%) were the dominant phyla, and interestingly, they (along with Salvia ketone content) were significantly and positively correlated with the fresh and dry weights of Salvia roots that were likewise positively correlated.…”

“…is a perennial herb in the family Labiatae, whose roots and rhizomes contain active ingredients (tanshinones and tannins) with therapeutic effects on diseases such as cardiovascular diseases, diabetes, and liver diseases (Liu et al, 2020c;Jiang et al, 2022a). S. miltiorrhiza is a medicinal herb widely grown in bulk in Henan, Sichuan, Shandong, and Shaanxi (Wang et al, 2019). However, as adoption of highly efficient monocultures can lead to a decrease in quality and yield, measures such as composite cultivation are needed to promote sustainable development (Liu et al, 2020a).…”

“…Compound cropping can, therefore, increase agroecosystem diversity and promote sustainable agriculture (Stomph et al, 2020). Studies have shown that complex planting can modify plant root natural environments (Wang et al, 2019), and stimulate the production of unique inter-root secretions (Casper and Castelli, 2007), which regulate plant growth and promote nutrient uptake, attract specific probiotic bacteria to form plant-soil feedbacks (PSF) (Neumann and Romheld, 2003;Bais et al, 2006), and influence microbial community formation (Sasse et al, 2018).…”

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

“…The soil microbial community, including its composition, diversity, and community stability, has become a crucial indicator for assessing soil health ( Hermans et al., 2017 ; Lehmann et al., 2020 ). Continuous monoculture of S. miltiorrhiza led to decreased contents of total phosphorus, total potassium, available phosphorus, and other nutrients in soils ( Wang et al., 2019b ). A decrease in bacterial community diversity and an increase in pathogenic fungal community diversity were found in the continuous monoculture soil of S. miltiorrhiza ( Liu et al., 2019 ; Zhou et al., 2019 ).…”

Continuous monoculture of crops has resulted in reduced yields and quality, as well as soil deterioration. Although traditional Chinese medicine residues (TCMRs) are known to promote plant growth and soil health, few studies have investigated their effectiveness in continuous monoculture soils. Here, we studied the impact of chemical fertilizers (CF) and four TCMRs with antibacterial activities on the growth of S. miltiorrhiza (a widely used medicinal plant in China), accumulation of active ingredients in plants, and soil health under continuous monoculture conditions. Compared with no fertilizer (CK) and CF, fermented Sophora flavescens radix residue (SFRf) and fermented and unfermented Moutan cortex residue (MCRf and MCRu, respectively) resulted in a reduction of the disease index of root rot, while CF did not. The CF and four TCMR treatments increased the accumulation of nitrogen (N) (42.8-124.6% and 17.0-101.7%), phosphorous (P) (19.8-74.7% and 8.3-27.4%), and potassium (K) (104.1-212.0% and 9.3-51.8%) in shoots and roots compared to CK. The differences in nutrient accumulation between the CF and TCMR treatments were statistically insignificant, excepted for the N accumulation in the roots. All fertilization treatments increased plant biomass compared to CK, with increases of 25.57-89.86% and 2.62-35.28% in shoots and roots, respectively. The SFRf treatment exhibited the most significant enhancement in both shoot and root biomass. CF significantly reduced the accumulation of seven active ingredients in roots by 23.90-78.95% compared to CK, whereas each TCMR increased accumulation of certain active ingredients. The TCMR treatments effectively improved the health of deteriorated soil by enhancing soil physicochemical properties, restoring the balance of the microbial community, recruiting beneficial bacteria, and reducing the relative abundance of the pathogen Fusarium. The SFRf treatment exhibited superior performance in improving soil health than other treatments. Overall, the TCMRs outperformed CF in restoring soil health and promoting the yield and quality of S. miltiorrhiza. These findings offer guidance for improving the health of continuous cropping soil and recycling TCMRs.

Rhizosphere soil microorganisms are critical in the plant's growth and soil health. Continuous crop cropping had significant effects on rhizosphere soil microbial community. To figure out the effects of continuous cropping of Glehnia littoralis on the composition, structure and diversity of rhizosphere soil microbial communities, this study brings to G. littoralis of 1 year (first cropping soil, FS), 2 years (continuous cropping soil, CS), and 0 years (Layland, control soil, CK) soil as the materials. The composition, structure, and diversity of soil fungi and bacteria in different planting years were analyzed by the Illumina high-throughput sequencing technology. The α-diversity of fungi in CS was significantly lower than that in other rotation systems. Proteobacteria, Acidobacteria, and Actinobacteria were the dominant bacteria, and Ascomycota, Basidiomycota, and Zygomycota were dominant phylum fungi. The relative abundance of Actinobacteria and Acidobacteria in the bacterial community decreased with the increase of stubbles, which may significantly reduce the microbial diversity and remedy the negative effects of continuous cropping of G. littoralis. The pH value, urease activity, and total nitrogen content were higher in the continuous cropping soil. Redundancy analysis showed that soil nutrients, pH value, and urease activity had significant effects on soil fungal and bacterial communities. Significant correlations were detected between soil total nitrogen and urease, and between soil total phosphorus and total potassium. In conclusion, continuous cropping changes soil nutrients, pH value, and urease activity, which, in turn, shifts the soil microbial community. The interaction and mutual influence of these factors may be the main cause of continuous cropping obstacle of G. littoralis.
