Abstract:
Under laboratory conditions，we studied the effect of pH，temperature，NaCl concentration and rhizosphere microorganisms(RM)inoculum size on the attachment of RM to the soybean root surface.Under the selected range of pH，temperature and NaCl concentration，the attachment of RM all showed an increasing and then decreasing trend，and peaked at pH 7.5，30℃ and 50 or 60 mmol·L-1 NaCl，respectively.The linear regression equation about attachment of RM and inoculum size was y=1.0021 x+0.2982，the correlation coefficient was R2=0.992 5，it showed the attachment of RM was significant positive correlated with inoculum size.
