Preferred citation for this article: Weng S.Y., 2026, Rhizosphere microbial structure in vineyard soils under integrated nutrient management, Molecular Soil Biology, 17(1): 51-60 (doi: 10.5376/msb.2026.17.0005) Abstract The rhizosphere microbial community in vineyard soil plays a crucial role in maintaining soil ecological function and improving grape yield and quality. Integrated nutrient management (INM), through the rational combination of chemical fertilizers, organic fertilizers, and bio-fertilizers, not only meets the nutrient requirements of grapes but also improves the soil environment and promotes the proliferation of beneficial microorganisms. This paper systematically reviews the types and functions of rhizosphere microorganisms, influencing factors, and their correlation with grape growth and quality, focusing on the relationship between INM and the rhizosphere microbial structure in vineyards. Results show that a rational INM model can significantly increase soil organic matter and fertility, promote the abundance of nitrogen-fixing and phosphorus-solubilizing functional microorganisms, thereby improving the rhizosphere microbial structure. Specifically, reducing chemical fertilizer application and applying liquid organic fertilizer can significantly increase soil microbial biomass (C, N) and enzyme activity, improving grape yield and quality; the combined application of organic and chemical fertilizers can increase the number of beneficial microorganisms such as actinomycetes in the soil. Methodologically, this study integrates traditional soil physicochemical testing, high-throughput sequencing, and bioinformatics analysis to perform multi-faceted analysis of vineyard rhizosphere samples. The conclusion indicates that INM can optimize rhizosphere microbial structure and enhance soil ecological stability, but further long-term, multi-regional integrated research is needed. Therefore, this study proposes future research recommendations and management policy recommendations.

As a core component of the agro-ecosystem, soil not only provides water and nutrients for grapes but also provides a habitat for a large number of microorganisms. These soil microorganisms maintain the ecological function and fertility of the vineyard through decomposing organic matter, cycling nutrients, and adjusting soil structure. A healthy soil ecosystem promotes root development, enhances vine resistance, and ultimately increases grape yield and quality (Zarraonaindia et al., 2015; Meissner et al., 2019). Therefore, studying the structure and function of vineyard soil ecosystems is of great significance for promoting the sustainable development of the grape industry. The rhizosphere is the most active area for interaction between plant roots and soil microorganisms. Grape roots secrete root exudates such as organic acids, sugars, and amino acids, providing a rich carbon source for rhizosphere microorganisms and attracting functional microbial communities such as nitrogen-fixing bacteria and phosphorus-solubilizing bacteria to colonize. Rhizosphere microorganisms not only participate in soil nutrient cycling, such as by fixing atmospheric nitrogen and dissolving insoluble phosphorus to improve nutrient availability, but also stimulate root growth by producing plant growth-promoting substances (such as indoleacetic acid and cytokinins). Furthermore, certain beneficial microorganisms possess the ability to antagonize soil-borne pathogens, thereby enhancing the disease resistance of grapevines. Studies show that a healthy and stable rhizosphere microbial community helps strengthen the nutrient absorption capacity and environmental stress response of grapevines, thus affecting fruit ripeness, sugar content, and flavor compound accumulation.
