Abstract:: In order to understand the effect of the modified fertilization mode on soil microbiome community structure,Chinese cabbage was collected as the research object，and Illumina MiSeq high throughput sequencing technology was used to analyze the rhizospheric fungal and bacterial community structure of Chinese cabbage under the condition of conventional fertilization and modified fertilization(fertilizer reduction，increasing organic fertilizer and soil conditioner).The results showed that the improved fertilization increased the yield of cabbage，alleviated soil acidification，and soil nutrient increased.There were significant differences between the microbial community and dominant groups of the two kinds of fertilization methods.The modified fertilization method led the abundance of rhizosphere microbiome increased，the community structure changed，and the dominant fungi groups varied.
