摘要： This study was conducted on Chinese cabbage to examine the effects of different fertilization combinations on cabbage quality, amino acid content, and the microbial community structure in rhizosphere soil. The findings provide valuable insights for improving nutrient management and soil fertility in local cabbage cultivation. The results showed that the T4 fertilization treatment significantly increased the content of seven essential amino acids compared to the control. All fertilization treatments enhanced soil pH, hydrolytic nitrogen, and effective phosphorus levels. The content of organic matter and readily available phosphorus varied depending on the fertilizer type. Microbial diversity was a key factor influencing the availability of effective phosphorus, potassium, and organic matter in the soil. The bacterial community was primarily dominated by Actinobacteria, Chloroflexi, Proteobacteria, Acidobacteria, Firmicutes, and Bacteroidetes, with fertilization treatments increasing the abundance of Acidobacteria and Firmicutes. The fungal community was mainly composed of Ascomycota, Basidiomycota, and Entomophthoromycota, with treatments reducing Ascomycota and enhancing Basidiomycota and Zygomycota. Soil pH, organic matter, hydrolytic nitrogen, and effective phosphorus were the primary factors affecting bacterial community composition, while fungal community shifts were driven by organic matter, hydrolytic nitrogen, and pH. The fertilization strategy using high-potassium organic fertilizer (200 kg/m2), aminobutyric acid (50 g/m2), and polyglutamate (1 kg/m2) significantly improved soil health, enhanced amino acid content, and promoted microbial diversity, making it a recommended fertilization approach for improving both cabbage quality and soil fertility.
