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。
採用平闆菌落計數法研究在不同土壤濕度條件下綠色木黴在土壤中的定殖動態及對尖孢鐮刀菌數量的影響。結果顯示:在3箇土壤濕度條件下,接種木黴後前4週均能顯著降低鐮刀菌的數量;與對照2(CK-H06)相比,處理(B2-H06)中木黴的孢子含量沒有顯著性變化。第1、2週,對照1(CK-B2)與處理(B2-H06)的鐮刀菌含量與土壤濕度呈顯著性正相關;在第5週,處理(B2-H06)的鐮刀菌和木黴菌含量與土壤濕度呈顯著性負相關。

The colonization of Trichoderma viride in the soil and the effect of T .viride on the amount of Fusari-um 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.oxys-porum and T.viride in the treatment group were negatively correlated with the soil moisture in the 5th week.
