摘要:

为研究长期施肥对葡萄土壤微生物群落多样性与抗生素耐药基因(antibiotics resistance genes,ARGs)的影响,以连续施肥5年的葡萄土壤为研究对象,并以邻近无种植且未施肥的地块表层土壤作为对照(CK),结合宏基因组测序技术和土壤理化性质分析,系统研究长期施肥对葡萄土壤微生物群落多样性及ARGs分布的影响。结果表明,与CK相比,长期施肥显著降低了土壤pH,且土壤养分含量也发生了显著变化。其中土壤有机质、全氮和全钾含量分别增加236.0%、243.3%和7.4%;碱解氮和铵态氮含量分别提升9.61和9.28倍;土壤微生物生物量碳和微生物生物量氮分别增加19.2%和8.53倍。此外,与CK相比,长期施肥使葡萄土壤中新增218种特定耐药基因,减少86种天然耐药基因。在土壤pH、有机质、全氮、全钾等理化因素的驱动下,硝化螺旋菌属(Nitrospira)和厌氧粘细菌属(Anaeromyxobacter)的相对丰度分别降低11.4%和3.1%;而假纤细芽孢杆菌属(Pseudogracilibacillus)、葡萄球菌属(Staphylococcus)、假双头斧形菌属(Pseudolabrys)和枝芽胞杆菌属(Virgibacillus)的相对丰度分别增加10.5%、6.1%、0.6%和5.4%。这些优势菌群的变化与耐药基因存在密切联系,且参与调节葡萄土壤菌群的整体功能与代谢。综上所述,长期施肥显著改善了葡萄土壤的理化性质,同时对土壤微生物群落多样性和ARGs数量产生了深远影响。

Abstract:

To examine the influence of long-term fertilization on the diversity of microbial community and the evolution of antibiotic resistance genes (ARGs) in grape soil, the grape soil continuously fertilized for 5 years was as material, with an adjacent plot of uncultivated and unfertilized soil as control (CK). Metagenomic sequencing technology and analysis of the physicochemical properties of the soil were employed to conduct a comprehensive investigation into the impact of long-term fertilization on the diversity of the microbial community and the distribution of ARGs in grape soil. The results revealed that, compared with CK, long-term fertilization resulted in a notable reduction of soil pH and a substantial alteration in soil nutrient composition. The contents of soil organic matter, total nitrogen and total potassium increased by 236.0%, 243.3% and 7.4%, respectively. Furthermore, the contents of alkali-soluble nitrogen and ammonium nitrogen increased significantly by 9.61 and 9.28 times, respectively. Additionally, the soil microbial biomass carbon and microbial biomass nitrogen increased by 19.2% and 8.53 times, respectively. Furthermore, compared with CK, long-term fertilization resulted in the addition of 218 new specific drug resistance genes and the reduction of 86 natural drug resistance genes in grape soil. The relative abundances of the genera Nitrospira and Anaeromyxobacter were decreased by 11.4% and 3.1%, respectively, as a consequence of the influence of physical and chemical factors such as soil pH, organic matter, total nitrogen and total potassium. The relative abundances of the genera PseudogracilibacillusStaphylococcusPseudolabrys and Virgibacillus increased by 10.5%, 6.1%, 0.6% and 5.4%, respectively. These changes in dominant bacterial groups were closely related to ARGs and played a role in regulating the overall function and metabolism of the grape soil microbiota. In conclusion, long-term fertilization could markedly enhance the physical and chemical properties of grape soil, while also should exert a profound influence on the diversity of soil microbial community and the number of ARGs.
