In practical applications, the effectiveness of biological control agents such as is often unstable due to different soil environments. Herein, we aimed to explore the control effect and intrinsic mechanism of in black soil and red soil in combination with tomato Verticillium wilt. application effectively controlled the occurrence of Verticillium wilt in red soil, reducing the incidence by 19.83%, but played a limited role in black soil. colonized red soil more efficiently. The pathogen decreased by 71.13% and 76.09% after the application of combinations in the rhizosphere and bulk of the red soil, respectively, while there was no significant difference in the black soil. Additionally, application to red soil significantly promoted phosphorus absorption. Furthermore, it significantly altered the bacterial community in red soil and enriched genes related to pathogen antagonism and phosphorus activation, which jointly participated in soil nutrient activation and disease prevention, promoting tomato plant growth in red soil. This study revealed that the shaping of the bacterial community by native soil may be the key factor affecting the colonization and function of exogenous .
在实际应用中，由于土壤环境不同，诸如[具体生物防治剂名称未给出]等生物防治剂的效果往往不稳定。在此，我们旨在结合番茄黄萎病，探究[具体生物防治剂名称未给出]在黑土和红壤中的防治效果及内在机制。[具体生物防治剂名称未给出]的施用有效控制了红壤中黄萎病的发生，发病率降低了19.83%，但在黑土中的作用有限。[具体生物防治剂名称未给出]在红壤中的定殖效率更高。在红壤根际和土体中施用[具体生物防治剂名称未给出]组合后，病原菌分别减少了71.13%和76.09%，而在黑土中无显著差异。此外，在红壤中施用[具体生物防治剂名称未给出]显著促进了磷的吸收。此外，它显著改变了红壤中的细菌群落，并富集了与病原菌拮抗和磷活化相关的基因，这些基因共同参与土壤养分活化和疾病预防，促进了红壤中番茄植株的生长。本研究表明，原生土壤对细菌群落的塑造可能是影响外源[具体生物防治剂名称未给出]定殖和功能的关键因素。
