The rhizosphere plays a vital role in the exchange of materials in the soil-plant ecosystem, and rhizosphere microorganisms are crucial for plant growth and development. In this study, we isolated two strains of rhizosphere bacteria separately from invasive and native . We conducted a control experiment to test the effects of these bacteria on the growth and competition of the two plant species using sterile seedlings. Our findings showed that the rhizobacteria strain isolated from significantly promoted the growth of invasive in monoculture compared to native . Both strains significantly enhanced the growth and competitiveness of invasive under competition conditions, regardless of their host source. Our study suggests that rhizosphere bacteria, including those from different host sources, can contribute to the invasion of by significantly enhancing its competitiveness.
根际在土壤-植物生态系统的物质交换中起着至关重要的作用，根际微生物对植物的生长发育至关重要。在本研究中，我们分别从入侵植物和本地植物中分离出两株根际细菌。我们进行了一项对照实验，使用无菌幼苗来测试这些细菌对两种植物物种生长和竞争的影响。我们的研究结果表明，与本地植物相比，从入侵植物中分离出的根际细菌菌株在单培养中显著促进了入侵植物的生长。在竞争条件下，无论其宿主来源如何，这两种菌株都显著增强了入侵植物的生长和竞争力。我们的研究表明，包括来自不同宿主来源的根际细菌，可以通过显著提高其竞争力来促进入侵植物的入侵。
