摘　　要：本试验采用传统的土壤稀释涂布平板法研究了转SacB、Vgb及JERFs36基因杨树对土壤微生物中主要类群细菌、丝状真菌及放线菌数量的影响。结果表明,转JERFs36基因杨树的土壤微生物总量平均为干土18.73×106cfu/g,转Vgb基因杨树为干土4.36×106cfu/g,转SacB基因杨树为干土242.28×106cfu/g。3种转基因杨树土壤根际主要微生物类群数量存在差异,但均未达到统计学显著水平,即3种转基因杨树对其根际土壤微生物主要类群的数量没有显著影响。In this paper, classical methods were adopted to explore the impact of transgenic poplar with JERFs36 gene, Vgb gene and SacB gene on soil microorganism （bacteria, filamentous fungi and aetinomycetes） group. The results showed that the amount of total soil microorganisms for JERFs36 gene, Vgb gene and SacB gene were 18.73 × 106 cfu/g dry soil,4.36 ×106 cfu/g dry soil and 242.28 × 106 cfu/g dry soil respectively. Amounts of main soil microorganism group were different, but showed no signifieances. That is to say, the three genes have no significant effect on the amount of main soil microorganism group.
