“…The continuous cropping of a single specie often leads to an imbalance in the soil microbial flora ( Fu et al, 2017 ). In comparison, the rotation cropping of different plant species is beneficial to maintain the balance of the rhizosphere soil microbial community ( Liu et al, 2022 ). The soil microbial community can serve as a sensitive bioindicator of soil health due to its quick response to environmental changes and close relationship with soil conditions and land management ( Sharma et al, 2011 ), which would consequently influence plant growth and health ( Gao et al, 2021 ).…”

Rhizosphere bacteria play important role in soil nutrient cycling and plant growth, and their richness and diversity are influenced by soil management systems. However, the specific changes in tobacco rhizosphere bacterial community structure in continuous and tobacco-rice rotation cropping systems remain uninvestigated. In this study, soil properties and the composition of the rhizosphere bacterial community in tobacco monocropping and tobacco-rice rotation cropping systems were analyzed. Moreover, the comparison of rhizosphere bacterial community structure between tobacco continuous and tobacco-rice rotation cropping systems was performed via high-throughput sequencing. The changes in the composition of the rhizosphere bacterial community were investigated at different tobacco growth stages. The results showed that continuous tobacco cropping increased the soil soluble organic carbon (SOC), total nitrogen (TN), and the content of other nutrients (e.g., available phosphorus and available potassium) compared to tobacco-rice rotation cropping. However, monocropping decreased bacterial alpha-diversity and altered the community composition when compared to the rotation cropping system. At the phylum level, the relative abundance of Proteobacteria, Gemmatimonadetes, and Bacteroidetes increased in the continuous cropping soil, while that of Acidobacteria, Firmicutes, and Actinobacteria decreased. At the genera level, the average abundance of the dominant genus Bacillus varied from 12.96% in continuous cropping libraries to 6.33% in the rotation cropping libraries (p < 0.05). Additionally, several other taxa, such as o_Acidobacteriales and Candidatus_Solibacter decreased from 7.63 to 6.62% (p < 0.05) and 4.52 to 2.91% (p < 0.05), respectively. However, the relative abundance of f_Gemmatimonadaceae and c_Subgroup_6 showed an increase of 1.46% (p < 0.05) and 1.63% (p < 0.05) in the tobacco-rice rotation cropping system, respectively. The results of NMDS indicated that the rhizobacteria community structure differed in the two cropping systems. In tobacco, the rhizosphere bacterial community structure showed no significant changes in the prosperous long-term stage and topping stage, but the composition changed significantly in the mature stage.

“…Limitations, and future perspectivesWe found that six chemical characteristics (pH, SOC, TN, AP, AK, C: N) had no signi cant different among the three tobacco-rice rotation treatments, challenging the previous thought that soil chemical properties are generally linked with fertilizations(Fang et al, 2020;Liu et al, 2022). Residual nutrients after previous plant harvest may have a signi cant in uence on the growth of tobacco and the soil nutrient content(Xiao et al, 2018; Hirzel et al, 2020).…”

“…In continuous cropping soil, microbial communities are exposed to root exudates of the same crop year after year, which leads to a reduction in the abundance of bene cial bacteria (e.g., Arthrobacter and Lysobacter) and the multiplication of detrimental bacteria (e.g., soil-borne pathogens) (Wu et al, 2017;Wang et al, 2022a).Crop rotation has been shown to increase crop yields by 20% with a lower nitrogen fertilization rate than that in continuous monoculture practices (Zhao et al, 2020). A paddy eld ecosystem with ood and drought rotation is considered a typical sustainable farmland ecosystem owing to its higher grain production and better soil conservation capacities (Zhu et al, 2016), which are bene cial for increasing bacterial and fungal richness and maintaining the balance of the rhizosphere soil microbial community (Liu et al, 2022). Rotational cropping practices have resulted in higher pineapple yields than those of continuous cropping, which may be associated with a signi cant change in the bacterial community structure (Chen et al, 2020a).…”

“…Thus, controlling chemical fertilizer application while ensuring high and stable yield is a key area of agricultural research. Limited use of organic nutrient resources and application of organic materials to replace some chemical fertilizers have been shown to effectively reduce the amount of chemical fertilizer needed, increase soil productivity, ensure crop yield, and improve local ecological functions ( Liu et al., 2022 ).…”

Carbonization of agricultural and forestry wastes is the main use of biochar application in agriculture. In this study, the effects of biochar on the physical and chemical properties of soil and diversity in rhizosphere microorganisms, leaf nutrients and fruit quality of acid red soil in “Shatangju” (Citrus reticulate cv.) orchard were studied using organic wastes and small-scale carbonization furnaces from orchards were used to produce biochar. The results showed that the finished rate of biochar produced from the organic wastes in the orchard was approximately 37%, and the carbon content of the finished product was as high as 80%. The results suggested that the biochar produced in the orchard could meet the annual consumption of the orchard. Applying biochar can improve the physical and chemical properties of acid soil in the “Shatangju” orchard by enhancing the availability of various mineral nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium and boron. The species and quantity of root and rhizosphere microbial communities (fungi, bacteria and archaea) increased, and the dominant bacterial group changed, manifested in the increase in microbial diversity. Biochar directly affected the soil pH value and increased the soil organic carbon content, which may be the main reason for the change in microbial diversity in the soil and rhizosphere of “Shatangju” in the orchard and pot tests. The fruit quality of each treatment group with biochar was also better than that of the control group and improved fruit coloring. In the pure soil test, whether or not chemical fertilizer was applied, 3% biochar amendments can provide a suitable pH value for “Shatangju” growth and are relatively stable. Regardless of whether or not fertilizer was applied, 1.5%-3% biochar improved the soil in the pot test. In the field, the biochar at a rate of 2.4 kg/plant to 3.6 kg/plant, respectively, was the best in improving soil physical and chemical properties, foliar nutrition and fruit quality. Therefore, the amount of biochar added in the open environment (if the garden) can be slightly adjusted according to the results of the closed environment test (pure soil test and pot test). In this experiment, we explored the self-recycling of organic carbon, mainly through the preparation of a simple small-scale biochar furnace suitable for the use by orchards, and selected the appropriate amount of biochar to improve the physical and chemical conditions of “Shatangju” orchard soil and increase fruit quality.
