Analysis of Functional Diversity of Rhizosphere Microbial Community of Panax quinquefolius L.in Tonghua County by Biolog-ECO Method
To explore the functional diversity of the rhizosphere microbial community of Panax quinquefolius L.in Tonghua county,Jilin province,Biolog-ECO microplate is used for analyzing the function and diversity of rhizosphere soil microorganisms in five locations,and the functional diversity of soil microbial communities has been analyzed by principal component analysis.The microbial communities of the samples use carbohydrates as the main carbon sources in the initial stage,and amino acids,carboxylic acids and polymers as the main carbon sources in the later,and the utilization rate of phenolic acids carbon sources is not high.Furthermore,six carbon sources including methyl pyruvate,D-glucosamine,α-D-glucosamine 1-phosphate,D-galacturonic acid,phenethylamine and L-serine,have a great influence on the carbon metabolic activity of soil microorganisms.This study analyzes the carbon source metabolism and community change characteristics of Panax quinquefolius L.rhizosphere microorganisms in Tonghua county,which will provide theoretical basis for understanding the disease mechanism and alleviating the growth disorder of Panax quinquefolius L..
