摘  要：
[目的]探究微生物施肥技术对草莓根腐病的防治效果,为进一步合理应用微生物肥料防治草莓重茬病害提供理论依据。[方法]在草莓生长期施用微生物肥料,于膨果期调查草莓根腐病发病情况,并采集土样提取土壤基因组DNA,通过PCR扩增建立文库,利用Miseq平台Illumina第二代高通量测序技术并结合相关生物信息学分析土壤细菌16S r RNA基因V3+V4区域和真菌ITS1区域的丰富度和多样性指数以及群落结构。[结果]微生物肥料可使草莓根腐病发病率降低36.3%,平均防效达63.9%;显著降低镰孢菌属的相对丰度,较对照区降低了97.56%,明显提高了有益细菌芽孢菌属的相对丰度,较对照区提高了30.37%。[结论]微生物肥料可有效改善土壤微生物区系并提高作物产量、改善草莓品质。

摘  要：
[Objective] To investigate the effect of microbial technology on the control of strawberry root rot,as well as to provide a theoretical basis for the further application of microbial technology to control strawberry stubble. [Method]The microbial fertilizer was applied during the growth of strawberry,and the occurrence of strawberry root rot was investigated in swelling period. The soil genomic DNA was extracted and the gene library was amplified by PCR. Miseq platform Illumina next generation sequencing and the bioinformatics were used to analyze the abundance and diversity indices of soil bacterial 16 S r RNA gene V3 + V4 region and fungal ITS1 region as well as the community structure. [Result] The incidence of strawberry root rot decreased by 36.3%,the average control efficiency reached 63.9%,and the relative abundance of Fusarium spp. decreased by 97.56% compared with the control. The relative abundance of beneficial bacteria was increased by 30.37% compared with the control. [Conclusion] Microbial fertilizer could improve soil microbial flora and crop yield,and improve the quality of strawberry.
