摘要:

为合理利用我国林地资源,探寻山莓(Rubus corchorifolius)林下种植的适宜林地类型,以山莓灌木丛为参照对象,选取重庆缙云山中亚热带典型植被中的马尾松(Pinus massoniana)、楠竹(Phyllostachys ubescens)和柑橘(Citrus reticulata)3种林地的山莓根际土壤,采用高通量测序法检测其真菌多样性,并分析它们与土壤养分间的关系。结果发现,马尾松和山莓林地中山莓根际土壤真菌多样性指数间无显著差异,但都显著高于楠竹和柑橘林地;子囊菌门(Ascomycota)、担子菌门(Basidiomycota)和被孢霉门(Mortierellomycota)是山莓根际土壤的优势真菌门,它们的总相对丰度在山莓、柑橘和马尾松林地中均占90%以上,在楠竹林地中占40%以上;山莓、马尾松、柑橘和楠竹林地间的关键差异菌属明显不同,依次分别为:篮状菌属(Talaromyces)和弯颈霉属(Tolypocladium)、绿僵菌属(Metarhizium)和青霉属(Penicillium)、曲霉属(Aspergillus)和毛壳菌属(Chaetomium)、未分类的子囊菌门菌属(Unclassified_k_Ascomycota)。土壤中的有效磷和有机碳含量是影响山莓根际土壤真菌群落分布的关键养分因子。山莓根际土壤真菌的主要功能类群在马尾松和山莓林地中均为腐生真菌,而在楠竹和柑橘林地中则分别为丛枝菌根真菌和寄生真菌。综上,4种林地中,马尾松和山莓林地间的山莓根际土壤养分良好,关键差异菌属均可能具有解磷功能,且真菌的物种组成相近、丰富度和多样性都显著高于柑橘和楠竹林地,可推荐用作林下栽培山莓的适宜林地。

Abstract:

This study aims to promote the rational utilization of China’s forest land resources and to identify suitable forest types for the understory cultivation of Rubus corchorifolius. Using R. corchorifolius shrubland as a reference,its rhizosphere soil were investigated in three typical mid-subtropical forest stands i.e. Pinus massonianaPhyllostachys ubescens,and Citrus reticulata in Jinyun Mountain,Chongqing. High-throughput sequencing was employed to analyze fungal diversity and its relationship with soil nutrients. Results showed that the fungal diversity index of rhizosphere soil was no significantly different between Pinus massoniana and R. corchorifoliu stands,but was significantly higher than that in Phyllostachys ubescens and C. reticulata stands. Ascomycota,Basidiomycota,and Mortierellomycota were the dominant fungal phyla,collectively accounting for over 90% of the totally relative abundance under R. corchorifoliusC. reticulata,and P. massoniana stands,while > 40% under Phyllostachys ubescens stand. The key differential fungal genera distinctly varied among the four stands:Talaromyces and Tolypocladium in the R. corchorifolius stand;Metarhizium and Penicillium in the Pinus massoniana stand;Aspergillus and Chaetomium in the C. reticulata stand;and Unclassified_k_Ascomycota in the Phyllostachys ubescens stand. Soil available phosphorus and organic carbon were the critical nutrient factors influencing the distribution of fungal communities in R. corchorifolius rhizosphere soil. The saprotrophic fungi were the primary functional groups under both Pinus massoniana and R. corchorifolius stands,whereas arbuscular mycorrhizal fungi and parasitic fungi were predominant under Phyllostachys ubescens and C. reticulata stands. Overall,the rhizosphere soil nutrients were favorable under Pinus massoniana and R. corchorifolius stands than under other two stands while the major key fungal genera might have the function of phosphorus solubilization. In conclusion,the Pinus massoniana and R. corchorifolius stands exhibited more favorable rhizosphere soil nutrients. Their key differential genera are likely capable of phosphorus solubilization,and they shared similar fungal species composition with significantly higher richness and diversity compared to the C. reticulata and Phyllostachys ubescens stands. Therefore,the Pinus massoniana forest stand is recommended as a suitable site for the understory cultivation of R. corchorifolius.
