In this experiment,cucumber was continuously monocropped in pots under greenhouse conditions for nine growing *** cucumber plant biomass was the lowest in the seventh growing season (Pbacterial or fungal community structures showed distinct differences between the phenolics amended soil and the control *** indices of bacterial community were significantly lower in the phenolic compounds mixture amended soil than in the control soil,while these of fungal community were significantly higher in the phenolic compounds amended soil (P<0.05),indicating that soil bacteria and fungi responded differently to amendments of *** conclusion,soil phenolic contents increased after cucumber was cultivated in the first growing season,but did not accumulate through growing seasons in natural *** of phenolics obviously inhibited cucumber growth and changed soil microbial *** unknown factors might influence these observed phytotoxic effects of artificially amended phenolics under natural conditions.
