| 中文摘要: |
| 采用平板菌落计数法研究在不同土壤湿度条件下绿色木霉在土壤中的定殖动态及对尖孢镰刀菌数量的影响。结果显示：在3个土壤湿度条件下, 接种木霉后前4周均能显著降低镰刀菌的数量; 与对照2(CK-H06)相比, 处理(B2-H06)中木霉的孢子含量没有显著性变化。第1、2周, 对照1(CK-B2)与处理(B2-H06)的镰刀菌含量与土壤湿度呈显著性正相关; 在第5周, 处理(B2-H06)的镰刀菌和木霉菌含量与土壤湿度呈显著性负相关。 |
| 英文摘要: |
| The colonization of Trichoderma viride in the soil and the effect of T. viride on the amount of Fusarium oxysporum were studied by plate culture count method. The results showed that the amount of F. oxysporum decreased significantly by the inoculation of T. viride under three soil moisture contents during the first four weeks. The amount of T. viride in the treatment group was not significantly changed compared to control group 2 during the first five weeks. There was no positive correlation between the soil moisture content and the amount of F. oxysporum in the control group 1 and treatment group during the 1st and 2nd weeks. The amount of F. oxysporum and T. viride in the treatment group were negatively correlated with the soil moisture in the 5th week. |
