“…Statistical Product Service Solutions (SPSS 26) software was used to conduct a one-way analysis of variance (ANOVA) test to obtain significant differences in the Sanqi fresh weight, soil physicochemical properties, and α-diversity (p < 0.05). The α-diversity (Chao and Shannon indices) and β-diversity were calculated using QIIME and the Bray-Curtis distance matrix, respectively [25,26]. Circos (https://cloud.oebiotech.cn/task/detail/circos/, accessed on 11 February 2024) was used to analyze the composition of microbiomes (phylum and genus).…”

Panax notoginseng (Sanqi) is a precious traditional Chinese medicine that is commonly cultivated using conventional management methods in agricultural systems in Yunnan, China, where it faces the challenge of continuous cropping obstacles (CCOs). However, the existence of Sanqi CCOs in Sanqi–pine agroforestry systems remains unclear. Here, we applied three types of exogenous organic acids (phthalic acid, palmitic acid, and phthalic + palmitic mixed organic acids) mainly derived from the root exudates of Sanqi to simulate the CCOs; then, we compared the effects on plant growth, soil physicochemical properties, soil microbes, and soil metabolites. We found that organic acid concentrations of >250 mg/kg reduced the fresh weight of Sanqi and the levels of total nitrogen, ammonium nitrogen, soil water content, total phosphorus, and pH value; these concentrations also increased the soil bacterial and fungal α-diversity. The type of organic acid, as opposed to the concentration and duration of treatment, had a vital impact on the structure of the bacterial and fungal community in Sanqi soils. Moreover, the organic acid concentrations of >250 mg/kg also decreased the complexity and stability of the bacterial and fungal network. In addition, the metabolic pathways in the soils under different organic acids included 17 differential metabolites (DMs), which were involved in steroid hormone biosynthesis. The structural equation models (SEMs) revealed that plant growth, soil edaphic factors, and soil metabolites had direct or indirect influences on soil microbial communities under different organic acid conditions. Our results suggest that any phthalic or palmitic acid concentrations at concentrations >250 mg/kg are detrimental to multiple aspects of Sanqi cultivation, confirming the presence of Sanqi CCOs in Sanqi–pine agroforestry systems.

“…They suggested that agroecological patterns significantly influenced the abundance and diversity of nematodes, but this was soil type dependent. Jia et al (2023) showed that when studying soil microbial changes in different tropical forests, it is necessary to consider topographical factors such as altitude and slope aspect or season. In addition, tree species identity, herbivory and disease may also potentially affect multiple ecosystem functions, such as soil carbon (Lu et al 2023;Ma et al 2024).…”
