To test the effects of different AMF（arbuscular mycorrhizal fungi） strains mixture inoculum on
cucumber seedling growth，seeds of cucumber were covered with 2 different AMF inoculums BF（mycorrhiza for
plants）and VT（mycorrhiza for vegetables）from Czech Republic after sawing in the trays in solar greenhouse．
Thirty-five days after inoculation the infection rates were 49.30%，37.65%，respectively．The plant height，
stem diameter，fresh and dry weight of those seedling inoculated with AMF were higher than that of the control．
Compared with the control，VT inoculation could significantly improve the root activity，chlorophyll content and
photosynthetic rate of cucumber leaves．Comprehensive analysis showed that VT had better effect in promoting the
growth of greenhouse cucumber seedlings.
