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.
