“…Among them, a decreased abundance of Acidobacteria and increased abundances of Proteobacteria and Bacteroidetes were found with the increase in monocropping years of S. avescens. Similar to the results of previous studies, continuous monocropping can easily reduce the abundance of bacteria and increase the abundance of fungi" or "number of bacterial species and increase the number of fungal species (trend of a transformation from "bacterial soil" to "fungal soil") [17,30], which can lead to soil failure, disease, and pest problems [32]. Accordingly, the majority of the soil fungi were phytopathogenic microorganisms and not conducive to plant growth [33], indicating that increasing the continuous monocropping years decreases soil fertility and increases plant disease incidence [34].…”

“…Continuous monocropping results in dynamic transformation of soil microorganisms [17,30]. Because at least two years of S. avescens cultivation is required to meet the criterion for effective ingredients used in clinical therapeutics [31], our study excluded the soil samples from the rst year of S. avescens monocropping.…”

“…The level of soil phosphorus content to a certain extent re ects the storage and supply capacity of phosphorus in soil [43]. The differences between rhizosphere and CK communities may also be associated with the higher content of AP in rhizosphere soil than in CK soil [17]. The pH value and TN and sucrase contents of rhizosphere soil were lower than those of CK soil, which led to an increase in abundance of some speci c groups.…”

“…Moreover, other factors such as phytotoxic compounds, soil-borne pathogens, soil physicochemical property changes, and nutrient de ciency can also contribute to the diversity of microbial communities [7,13,14]. Many plants have been reported to suffer from high mortality, declines in yield and quality, and stunting caused by continuous monocropping systems, such as notoginseng [15], soybean [16,17], rice [18], peanut [7], and cucumber [19]. For these reasons, agricultural activities should be paid more attention, especially when exploring the underlying mechanism of continuous monocropping and soil sickness.…”

Background: Continuous monocropping can affect the physicochemical and biological characteristics of cultivated soil. Sophora flavescens is a valuable herbal medicine and sensitive to continuous monocropping. Currently, diversity patterns of soil microbial communities in soil continuous monocropping with S. flavescens have not been extensively elucidated.Results: In this study, comparative 16S rDNA and internal transcribed spacer (ITS) MiSeq sequencing analyses were used to examine the taxonomic community structure and microbial diversity in nonrhizosphere soil (CK) and rhizosphere soils (SCC, TCC, and FCC) sampled from fields that had undergone two, three, and five years of continuous monocropping, respectively. Among the microbial communities, a decreased abundance of Acidobacteria and increased abundances of Proteobacteria and Bacteroidetes were found with the increase in monocropping years of S. flavescens. As the continuous monocropping time increased, the diversity of the bacterial community decreased, but that of fungi increased. Redundancy analysis also showed that among the properties of the rhizosphere soil, the available phosphorus, organic matter, total nitrogen, and sucrase had the greatest impacts on the diversity of the rhizosphere microbial community. Moreover, a biomarker for S. flavescens soil was also identified using the most differentially abundant bacteria and fungi in soil samples.Conclusions: Our study indicates that long-term monocropping exerted great impacts on microbial community distributions and soil physicochemical properties. The relationship between microbial community and physicochemical properties of rhizosphere soil would help clarify the side effects of continuous S. flavescens monocropping. Our study may aid in uncovering the theoretical basis underlying obstacles to continuous monocropping and provide better guidance for crop production.

“…Even if the field management regime is good, the crop may still suffer from reduced crop growth and development, decreased yield quality, and an increase in disease ( Aparicio and Costa, 2007 ; Li et al, 2016 ; Sui et al, 2019 ; Liu et al, 2020 ). According to a recent study, the secretion of metabolites and leached substances from the plant increase under the CC system ( Liu et al, 2020 ). This can promote the reproduction of pathogenic bacteria and increases the number and types of harmful microorganisms.…”

Continuous cropping (CC) restricts the development of the medicinal plant cultivation industry because it alters soil properties and the soil microbial micro-ecological environment. It can also lead to reductions in the chemical contents of medicinal plants. In this study, we intercropped continuously cropped Pogostemon cablin (patchouli) with turmeric or ginger. High-throughput sequencing was used to study the soil bacteria and fungi. Community composition, diversity, colony structure, and colony differences were also analyzed. A redundancy analysis (RDA) was used to study the interactions between soil physical and chemical factors, and the bacteria and fungi. The correlations between the soil community and the soil physical and chemical properties were also investigated. The results showed that intercropping turmeric and ginger with patchouli can improve soil microbial abundance, diversity, and community structure by boosting the number of dominant bacteria, and by improving soil bacterial metabolism and the activities of soil enzymes. They also modify the soil physical and chemical properties through changes in enzyme activity, soil pH, and soil exchangeable Ca (Ca). In summary, turmeric and ginger affect the distribution of dominant bacteria, and increase the contents of the active ingredient in patchouli. The results from this study suggested that the problems associated with continuously cropping patchouli can be ameliorated by intercropping it with turmeric and ginger.

The benefits of no-till to crop yield depend on environment and crop sequence; thus, understanding their interactions is a long-term process. This 44-year field experiment examined grain yield, yield stability, and adaptability of continuous winter wheat (Triticum aestivum L.) (Ct-WT), continuous soybean [Glycine max (L.) Merrill] (Ct-SY), continuous grain sorghum [Sorghum bicolor (L.) Moench] (Ct-GS), soybean-winter wheat rotation (SY-WT), and soybean-grain sorghum rotation (SY-GS) under three tillage systems (NT, no-tillage; RT, reduced tillage; CT, conventional tillage) near Ashland Bottoms, KS. The temporal variation across the studied years allowed us to evaluate treatments under low-and high-yielding environments. Crop rotation consistently outyielded continuous cropping, and the advantage was enhanced when integrated with NT. Yield stability decreased under NT continuous cropping in most systems. Wheat was adaptable to low-and high-yielding environments with similar grain yield and yield stability among treatments, except for NT Ct-WT, which had the lowest yield stability and grain yield (2.5 vs. 3.5 Mg ha −1 ).Soybean grain yield was greater under rotation than Ct-SY (2.7 vs. 2.0 Mg ha −1 ) and under NT than RT and CT (2.6 vs. 2.4 Mg ha −1 ), with similar yield stability. Soybean grown after wheat was more adaptable to low-yielding environments and grown after sorghum to high-yielding environments. Sorghum in NT SY-GS was adaptable to low-and high-yielding environments and had the greatest yield (6.2 Mg ha −1 ) and yield stability. This long-term study demonstrated the advantages of crop rotation combined with NT on grain yield, yield stability, and crop adaptability.
