Background Ginseng red skin root syndrome (GRS) is one of the most common ginseng diseases. It leads to a severe decline in ginseng quality and seriously affects the ginseng industry in China. However, as a root disease, the characteristics of GRS rhizosphere microbiome are still unclear. Methods The amplicon sequencing technology, combined with bioinformatics analysis, was used to explore the relationship between soil ecological environment and GRS. Results There were significant differences in the diversity and richness of soil microorganisms between the rhizosphere with different degrees of disease, especially between healthy ginseng (HG) and heavily diseased groups. We also found that bacterial communities underwent multiple changes between complex stability and simple instability in different ginseng rhizospheres through the established interaction networks. The GRS group also had more competition with each other and ecological niche separation than the HG group. The fungal community's stability decreased significantly in the early stages of the disease, followed by the formation of a stable and complex fungal community. The GRS groups significantly increased interspecies cooperation and ecological niche overlap in the fungal network than the HG group. Microbes closely related to potential pathogenic fungi were also identified according to the interaction network, which provided clues for looking for biological control agents. Finally, the Distance-based redundancy analysis (dbRDA) results indicated that total P (TP), available K (AK), available P (AP), catalase (CAT), invertase (INV) are the key factors that influence the microbial communities. Conclusions This study collectively analyzed the changing characteristics in ginseng rhizosphere and provided the basis for soil improvement and biological control of field-grown ginseng.

“…The cultivation years of the farmland affected the richness of the bacterial community, and the increase of cultivation age reduced the diversity of the bacterial community and changed the community structure and composition (Chang et al, 2021 ; Tong et al, 2021 ). Continuous cropping has caused the aggravation of soil-borne diseases in farmland, resulting in a decline in crop quality and yield, and severely restricted the productivity and sustainable development of farmland ecosystems (Arafat et al, 2019 ; Gao et al, 2020 ; Tian et al, 2020 ).…”

The shortage of land resources restricts the sustainable development of agricultural production. Multiple cropping has been widely used in Southern China, but whether the continuous planting will cause a decline in soil quality and crop yield is unclear. To test whether multiple cropping could increase grain yield, we investigated the farmlands with different cultivation years (10–20 years, 20–40 years, and >40 years). Results showed that tobacco-rice multiple cropping rotation significantly increased soil pH, nitrogen nutrient content, and grain yield, and it increased the richness of the bacterial community. The farmland with 20–40 years of cultivation has the highest soil organic carbon (SOC), ammonium nitrogen, and grain yield, but there is no significant difference in the diversity and structure of the bacterial community in farmlands with different cultivation years. The molecular ecological network indicated that the stability of the bacterial community decreased across the cultivation years, which may result in a decline of farmland yields in multiple cropping system> 40 years. The Acidobacteria members as the keystone taxa (Zi ≥ 2.5 or Pi ≥ 0.62) appeared in the tobacco-rice multiple cropping rotation farmlands, and the highest abundance of Acidobacteria was found in the farmland with the highest SOC and ammonium nitrogen content, suggesting Acidobacteria Gp4, GP7, GP12, and GP17 are important taxa involved in the soil carbon and nitrogen cycle. Therefore, in this study, the multiple cropping systems for 20 years will not reduce the crop production potential, but they cannot last for more than 40 years. This study provides insights for ensuring soil quality and enhancing sustainable agricultural production capacity.

“…The composition and structure of the bacterial community In order to clarify the microbial community structure in the B. chinense rhizosphere, two taxonomic levels (phylum and genus) were analyzed.As shown in Fig3A,13 bacterial phyla were detected in the soil from different cropping practices. The dominant bacterial phyla in the B. chinense rhizosphere soil were Proteobacteria (27%), followed by Actinomycetes (22%), Acidobacteria (20%), and Chloro exi (9%).…”

“…However, due to the limited available land and maximum economic bene ts, the continuous cultivation of B. chinense is becoming increasingly popular. Studies have shown that long-term continuous cropping alters physical properties of the soil [12] and the soil microbial community structure, resulting in a diminished community of bene cial microorganism in soil, an increase in the pathogenic microorganisms, and a decline in the yield and quality of medicinal materials [13]. For example, the continuous planting of American ginseng [14] and Sophora avescens [15] not only weakened soil microbial diversity and amassed fungal root pathogens, but also changed soil physical properties, resulting in decreased crop yield and quality.…”

It is of great importance to understand the effects of cropping practices of Bupleurum chinense on the properties of rhizosphere soil. Therefore, the chemical properties of rhizosphere soil and the rhizosphere microbiome were assessed in the field trial with Bupleurum and three cropping practices (continuous monocropping, Bupleurum-corn intercropping and Bupleurum-corn rotation). The results showed cropping practices changed the chemical properties of the rhizosphere soil and composition, structure and diversity of the rhizosphere microbial communities. Continuous monocropping of Bupleurum chinense not only decreased soil pH and the contents of NO3--N and available K, but also decreased the alpha diversity of bacteria and beneficial microorganisms. However, Bupleurum-corn rotation improved soil chemical properties and reduced the abundance of harmful microorganisms. Soil chemical properties, especially the contents of NH4+-N, soil organic matter (SOM) and available K, were the key factors affecting the structure and composition of microbial communities in the rhizosphere soil. These findings could provide a new basis for overcoming problems associated with continuous cropping and promote development of B. chinense planting industry by improving soil microbial communities.
