| 摘 要： | 通过盆栽试验研究生防制剂中厚孢轮枝菌在烤烟K326和云85根际的定殖情况及对根际微生物的影响。结果表明施入生物菌剂2周后厚孢轮枝菌能在烤烟外根际、根表分离到，但在根内不能分离到或分离数极少，在4周、6周时外根际、根表的分离数达到最大，根内分离数仍很少，8周时分离数又减少。制剂处理后烤烟根际细菌、真菌和放线菌数量在2周时明显减少，4周时有所回升，6周和8周时与对照达到平衡。结果表明厚孢轮枝菌可以在烟草外根际、根表定植，初期对土壤微生物具有一定的抑制作用。 |

| Abstract: | A pot experiment was conducted to determine the colonization of Verticillium chlamydosporium Goddard ZK7 on the tobacco rhizophere and its influence of rhizophere microbes. The resulus indicated that ZK7 was isolated from tobacco rhizosplane and ectorhizosphere but not endorhizosphere two weeks, after inoculation the colony forming units of ZK7 on rhizoplane and ectorhizosphere were the higher at four and six weeks, few in endorhizosphere. By eight weeks, the CFU decreased. The amount of fungi, bacteria and actinomyces on tobacco rhizophere were lower at two weeks, went up again at four weeks and reached to balance at six and eight weeks by ZK7 treatment. The results demonstrated that ZK 7 can colonize on rhizosplane and ectorhizosphere of tobacco. |
