| 摘 要： | 本文报道了利用拮抗链霉菌防治马铃薯疮痂病的大田试验研究。拮抗链霉菌接种在0.8公顷的病田中。不同接种量和接种方法均显著地影响防治效果。3年的试验表明:拮抗菌系以蛭石接种形式防效优于种薯浸泡。一般情况下,连续2年接种或高接种量的防效优于1年或低接种量的防效。不同菌系的防效差异明显,单个拮抗菌的防效优于2个拮抗菌混合使用的效果。甜玉米和大豆轮作结合拮抗菌显著降低了马铃薯疮痂病的危害。

| Abstract: | Biocontrol of potato scab by Streptomyces strains was evaluated in a 3 years field trial. Antagonistic strains of Streptomyces were inoculated into scab conducive soil in a 0.8 ha field. Inoculum dose and inoculation strategy both significantly influenced biocontrol efficacy. Vermiculite inoculation of antagonistic strains provided better scab control than tuber dip treatments in all 3 years this study. Generally, 2 years consecutive inoculation or higher dose application (45 ml) reduced scab more than single year inoculation or lower dose (15 ml) numerically. Additionally, individual antagonistic strains performed better than strain combinations, and strains differed significantly in the levels of biocontrol achieved. Finally, rotation crops (sweet corn and soybean) combined with antagonistic strains provided significant control of potato scab. |
