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.%采用日光温室穴盘育苗，在黄瓜播种时接种2种不同的捷克商品丛枝菌根真菌（AMF）组合菌剂 BF 和 VT，比较了不同菌剂对黄瓜苗期生长的影响。结果表明：VT 和 BF 组合菌剂均能不同程度地侵染黄瓜幼苗根系，接种35 d 时侵染率分别为49.30%、37.65%；接种 BF 和 VT 菌剂的幼苗株高、茎粗、干质量、鲜质量均明显高于未接菌处理，且以接种 VT 菌剂表现最佳；与未接菌对照相比，接种 VT 菌剂可使黄瓜幼苗的根系活力、叶绿素含量、光合速率显著提高，表明蔬菜专用菌剂 VT 对黄瓜幼苗生长有较好的促进效果。
