Abstract:

采用田间试验、微生物培养、BIOLOGGN微平板培养分析,研究了新开地、连作地施用生态有机肥前后土壤微生物多样性与番茄青枯病的关系。结果表明,新开地没有发生青枯病,连作地番茄青枯病发病率为100%,连作地施用生态有机肥后,青枯病发病率降低至49.86%,土壤真菌、放线菌的数量略微增加,细菌的数量变化不大,但平板中真菌、细菌、放线菌的不同形态菌落数明显增多。新开地、施用生态有机肥处理土壤微生物群落在BIOLOGGN微平板温育过程中的AWCD值、Shannon指数、Simpson指数、McIntosh指数、Alatalo均匀度均显著高于连作地土壤,PIE相遇几率则相反。新开地与施用生态有机肥土壤之间无显著差异。由此说明,施生态有机肥能提高土壤微生物多样性,从生态水平上抑制番茄青枯病的发生。
