“…PCA analysis also confirmed that Principal Component 1 (PC1) and Principal Component 2 (PC2) were the two most different characteristics that led to the microbial and bacterial communities of different varieties of coconut intercropping and their contributions to bacterial diversity were 67.07 and 11.29%, respectively. It showed that it was not only one factor that affected soil microorganisms in coconut intercropping of the same variety, but multiple factors (Yanxia et al, 2018;Stefan et al, 2021).…”

To explore the bacterial diversity and community structure characteristics of the rhizosphere soil of fruit type coconuts of different varieties under the intercropping pineapple model, the Illumina high throughput sequencing technology was used to detect the composition and diversity of soil microorganisms. Furthermore, the correlation between the physical and chemical properties of soil and the characteristics of the rhizosphere soil community was analyzed. The contents of OM, EC, AN, AP, AK, ACa, and AMg in coconut rhizosphere soil under intercropping were significantly higher than those under coconut monocropping. However, the soil pH value of the intercropping mode decreased significantly. The diversity of bacteria in the rhizosphere soil of coconut intercropped pineapple was higher than that of coconut monocropped. The diversity of bacteria in the rhizosphere soil of different varieties of coconuts was also different: The order of bacterial diversity was JG > JYT > JYO > JH. The dominant bacteria of the rhizosphere soil, in order, were Proteobacteria,
