摘要:

探究紫斑牡丹(Paeonia rockii)单作及其分别与大豆(Glycine max)、苜蓿(Medicago sativa L.)间作对根际土壤微生物群落结构的影响,为紫斑牡丹生态种植模式优化提供理论依据。以紫斑牡丹单作为对照,分别设置紫斑牡丹-大豆间作和紫斑牡丹-苜蓿间作处理,采集根际土壤样品,利用高通量测序技术分析细菌与真菌群落组成与多样性。结果表明:除速效钾外,间作大豆或苜蓿对土壤有效养分含量无显著影响,但改变了根际土壤的微生物群落结构。间作苜蓿提高了细菌群落的丰富度,间作大豆对真菌群落的丰富度与多样性无显著影响;间作大豆增加了变形菌门(Proteobacteria)、放线菌门(Actinobacteriota)和担子菌门(Basidiomycota)等有益菌群的相对丰度,并降低了病原菌镰刀菌属(Fusarium)的相对丰度。综上,紫斑牡丹间作有助于提升根际土壤有益菌丰度并抑制病原菌富集,其中间作大豆在改善真菌群落结构方面更具优势,更有利于改善紫斑牡丹根际土壤微生态环境。

Abstract:

This study aimed to investigate the effects of monocropping of Paeonia rockii and its intercropping with Glycine max and Medicago sativa L., respectively, on the rhizosphere soil microbial community structure, providing a theoretical basis for optimizing the ecological planting patterns of P. rockii. Using P. rockii monoculture as the control, treatments of P. rockii-G. max intercropping and P. rockii-M. sativa intercropping were established. Rhizosphere soil samples were collected, and high-throughput sequencing technology was used to analyze the composition and diversity of bacterial and fungal communities. The results indicated that, with the exception of available potassium, intercropping with soybean or alfalfa had no significant effect on soil available nutrient content but altered the rhizosphere microbial community structure. Intercropping with alfalfa increased the richness of bacterial communities, intercropping with soybean had no significant effect on the richness and diversity of fungal communities. Additionally, intercropping with soybeam increased the relative abundance of beneficial microbial groups such as Proteobacteria, Actinobacteriota, and Basidiomycota, and reduced the relative abundance of the pathogenic fungus Fusarium. In conclusion, intercropping of P. rockii helped enhance the abundance of beneficial rhizosphere microbes and suppressed pathogen enrichment. Intercropping with soybean showed greater advantages in improving the fungal community structure, making it more conducive to improving the rhizosphere soil micro-ecological environment of P. rockii.

Key words: Paeonia rockii, intercropping, rhizosphere soil, microbial community, richness, diversity
