Investigation of Rhizosphere Fungi in Pinus tabuliformis Forests in Beijing ---- Taking Songshan National Nature Reserve as An Example
Fungi play an important role in decomposing organic matter, preserving soil fertility and promoting nutrient cycling in soil ecosystem. This study aims to explore the diversity of rhizosphere fungi in natural and artificial Pinus tabuliformis forests, and provide a scientific basis for the sustainable development of pine forests in Beijing urban and surrounding mountainous areas, as well as the rational development and sustainable utilization of rhizosphere fungi resources. In the study, the number, species and distribution characteristics of fungi in the rhizosphere of natural and artificial P. tabuliformis forests were analyzed by using MMN solid plate culture method and first generation sequencing technology. The results are as follows. (1) The species of rhizosphere fungi in natural P. tabuliformis forests are more abundant than those in artificial forests, and Zygomycota and Ascomycotina are the dominant fungal colonies. (2) Penicillium is the main dominant colony in the rhizosphere of natural P. tabuliformis forests, and Umbelopsis is the main dominant colony in the rhizosphere of artificial forests. (3) Penicillium, Umbelopsis, Mucor, Fusarium and Trichoderma are the dominant fungi in the rhizosphere soil of P. tabuliformis forests. (4) The number of groups and individuals of rhizosphere fungi in natural P. tabuliformis forests is higher than that in artificial forests. This study preliminarily screened and identified two dominant fungi in the rhizosphere of P. tabuliformis forests, and could provide a basis for the protection and rational development of rhizosphere fungi resources.

【目的】研究施用棉秆炭,连作棉花根际土壤真菌群落多样性与土壤理化性质及黄萎病病害的关系,为棉秆的合理利用和防治棉花连作障碍提供科学依据和理论指导。【方法】以棉秆移除(NPK)和棉秆还田(NPKS)为对照,采用常规分析和454高通量测序技术,研究棉秆移除基础上施用常量棉秆炭(22.50 t/hm<sup>2</sup>,NPKB1)和增量棉秆炭(45.00 t/hm<sup>2</sup>,NPKB2)条件下,新疆棉花根际土壤真菌群落多样性、理化性质和黄萎病病害发生的相关性。【结果】施用棉秆炭连作棉花根际土壤真菌多样性和理化性质有显著相关性。经过2年的2%棉秆炭的施用显著降低了真菌多样性。真菌NPKS和NPKB2处理OTU丰度分别显著降低了15.63%和46.25%(PGibberella、Fusarium和Verticillium等病原真菌数量较NPK处理显著降低。施用棉秆炭显著增加了棉花根际土壤中有机质、速效钾和速效氮的含量,而速效磷的含量则降低;对pH的影响不显著,但显著提高了土壤的电导率。RDA分析中,土壤有机质和速效氮是影响棉花根际土壤真菌群落结构的重要环境因素。与NPK处理和NPKS处理相比,NPKB1处理增加了黄萎病病害发病率和病情指数,NPKB2处理黄萎病病害发病率下降不显著,病情指数分别降低了2.2%和15.0%。Verticillium数量与黄萎病发病率和病情指数呈极显著正相关。施用棉秆炭降低了棉花黄萎病病原菌数量,与NPK处理相比,增量棉秆炭Verticillium数量显著降低了63.83%。与NPK处理和NPKS处理相比,NPKB1处理增加了黄萎病病害发病率和病情指数,NPKB2处理黄萎病病害发病率下降不显著,病情指数分别降低了2.2%和15.0%。【结论】施用棉秆炭降低了连作棉花根际土壤真菌多样性,减少了黄萎病病原菌数量,增加了连作棉花根际土壤养分含量。虽然没有显著降低棉花黄萎病发病率,但有缓解病害发病程度的趋势。
