摘要
植物附生微生物与植物建立了独特的共生关系,对植物的生长、免疫防御和环境适应有重要影响。然而,施肥方法对附生微生物群落的影响及其与药用植物产量和质量的相关性仍不清楚。在本研究中,我们进行了田间施肥试验,并利用高通量测序数据分析了丹参不同器官(根、茎和叶)附生细菌和真菌群落的组成及其与植物生长的相关性。结果表明,施肥对有效成分和激素含量、土壤理化性质以及附生微生物群落的组成有明显影响。施肥后,植物表面富集了核心微生物群落,主要由固着菌、蛋白菌和放线菌中的细菌以及子囊菌和子囊菌中的真菌组成。此外,植物生长激素也是导致 S. miltiorrhiza 附生微生物群落发生变化的主要因素。因此,最有效的施肥方法是在施基肥的同时施叶面肥。这项研究为研究微生物群落功能与药蜀葵品质之间的相关性提供了一个新的视角,也为优质药用植物的栽培和可持续发展提供了理论依据。
Impacts of fertilization methods on Salvia miltiorrhiza quality and characteristics of the epiphytic microbial community
Plant epiphytic microorganisms have established a unique symbiotic relationship with plants, which has a significant impact on their growth, immune defense, and environmental adaptation. However, the impact of fertilization methods on the epiphytic microbial community and their correlation with the yield and quality of medicinal plant was still unclear. In current study, we conducted a field fertilization experiment and analyzed the composition of epiphytic bacterial and fungal communities employing high throughput sequencing data in different organs (roots, stems, and leaves) of Salvia miltiorrhiza, as well as their correlation with plant growth. The results showed that fertilization significantly affected the active ingredients and hormone content, soil physicochemical properties, and the composition of epiphytic microbial communities. After fertilization, the plant surface was enriched with a core microbial community mainly composed of bacteria from Firmicutes, Proteobacteria, and Actinobacteria, as well as fungi from Zygomycota and Ascomycota. Additionally, plant growth hormones were the principal factors leading to alterations in the epiphytic microbial community of S. miltiorrhiza. Thus, the most effective method of fertilization involved the application of base fertilizer in combination with foliar fertilizer. This study provides a new perspective for studying the correlation between microbial community function and the quality of S. miltiorrhiza, and also provides a theoretical basis for the cultivation and sustainable development of high-quality medicinal plants.
