摘要： Fertilization influences the grape (V. vinifera) quality, soil biochemical profiles and bacterial diversity. Twenty-five experiment plots of grape (V. vinifera L. cv. Cabernet sauvignon, 4-year old) were assigned into five groups and treated with four fertilization schedules (inorganic, organic, combined fertilizers, and soil conditioners) or without fertilization (Blank control). Properties of soil chemistry and grape quality were determined, and bacterial diversity was analyzed. Soil organic matter was increased by organic and combined fertilizers; available N, P and K and total N contents were increased by all fertilization schedules. Inorganic fertilizers increased tannin content; organic fertilizers increased total phenols and decreased tannin; combined fertilizers decreased soluble solids; and soil conditioners only increased tannin and decreased the total soluble solids, phenol compounds, titratable acids and sugar-acidity ratio. 16S rRNA sequencing analysis showed Micrococcaceae, Cytophagaceae and Streptomycetaceae abundance was increased by inorganic, organic and combined fertilizers, respectively. In comparison with inorganic fertilizers, soil conditioners reduced the abundance of Hyphomicrobiaceae, Micromonosporaceae, Rhodospirillaceae and Sphingomonadaceae. Canonical correspondence analysis showed that soil available N and P as well as grape anthocyanin contents were correlated with Halomonas, Pseudomonas, Rhodoplanes, Steroidobacter and Streptomyces abundance. Application of fertilizers increased soil fertility and grape berry quality via changing profiles of soil bacteria, including Streptomycetaceae, Hyphomicrobiaceae Micrococcaceae and Cytophagaceae families.
