摘要:

为探究生物菌剂木霉菌对切花月季病害的防控效果,在月季苗期施用300倍木霉菌可湿性粉剂。结果表明,施用木霉菌可促进和丰富月季根际、根内的真菌物种种类分布,对土壤中真菌及根内微生物多样性影响较大,OTU个数增加,特别根际真菌指数Shannon、Simpson及PD指数均高于清水对照和化学药剂甲基硫菌灵,说明施用木霉菌后使土壤真菌种类更加丰富,而且提高了一些有益菌的丰度。从对月季霜霉病的防治效果来看,300倍木霉菌及800倍50%甲基硫菌灵3次施药后相比清水对照均表现出显著差异,木霉菌防病和治疗效果达87.35%,比化学药剂甲基硫菌灵防效略高。

Abstract:

To explore the prevention and control effect of biological fungus Trichoderma on the diseases of cutting-rose, 300 times Trichoderma wettable powder was used at the seedling stage of cutting-rose. The results showed that Trichoderma could promote and enrich the distribution of fungal species in the rhizosphere and roots of rose, and had a great impact on the diversity of fungi and microorganisms in the soil. The number of OTU increased, and the rhizosphere fungal indexes, namely Shannon, Simpson and PD indexes, were higher than those of the control and chemical agent thiophanate methyl treatment, indicating that Trichoderma could enrich the species of soil fungi and increase the abundance of some beneficial bacteria. From the perspective of the control effect on rose downy mildew, 300 times of Trichoderma and 800 times of 50% thiophanate methyl showed significant differences compared with the control. The disease prevention and treatment effect of Trichoderma was 87.35%, which was slightly higher than that of chemical agent thiophanate methyl.
