摘　　要：以无菌水和10μg/mL涕灭威作为两组对照,研究了绿色木霉发酵液原液及不同稀释液对北方根结线虫卵囊、分散卵粒孵化及二龄幼虫活性的影响。在原液、5×、10×、20×及50×稀释液浓度下,对卵囊孵化的相对抑制率分别是99.45%、89.44%、85.61%、74.32%、61.75%,均与无菌水对照差异极显著,其原液与10μg/mL涕灭威两者间差异不显著。在原液、5×稀释液浓度下,对分散卵粒孵化的相对抑制率分别是99.04%、96.17%,均与无菌水对照差异极显著,与10μg/mL涕灭威三者之间差异不显著;对二龄幼虫的校正死亡率分别是96.39%、88.38%,均与无菌水对照差异极显著,绿色木霉原液与10μg/mL涕灭威两者间差异不显著。The effects of T. viride at the different concentrations on the hatching of egg masses and individual eggs and juvenile of M. halpa were investigated. The hatching of egg masses was suppressed by 99.89% ,92.85% ,85.66% ,79.72% at the original,5 ×, 10 ×,20 × diluted solution, respectively. The difference between these treatments and water control was highly significant while that between the original solution and 10 μg/mL Temik control was insignificant. The hatching of individual eggs was suppressed by 99.04% and 96.17% at the original and 5 × diluted solution, respectively, the difference between the two treantments and water control was highly significant while that between the two treatments and 10 μg/mL Temik control was insignificant. The corrected mortality of juveniles was 96.39% and 88.38% at the original and 5 × diluted solution, respectively,the difference between the two treantments and water control was highly significant while that between the original solution and 10μg/mL Temik control was insignificant.
