Abstract：By PCR-DGGE method，the paper studies the effect of companion planting Chinese
onion Allium fistulosum L. var. giganteum Makino on the bacterial communities in root zone of grafted
cucumber（Cucumis sativus L.）．The results showed that with test plants companion planting，the
Chinese onion decreased the diversity and evenness indices of bacterial communities in root zone of
grafted cucumber．And the diversity of soil bacterial communities varied with the growing stages of
cucumber．The sequencing of DGGE bands indicated that the characteristic bands of companion planting
Chinese onion were classified as Acidobacteria，Actinobacteria，Sphingomonas and Pseudomonadaceae，
respectively.
