Characteristics of Soil nitrogen Retention and Related Functional Microorganism in Soils of Main Afforestation Species in Subtropical Region

Abstract

Objective: In this study, five plantations of Phoebe bournei, Michelia macclurei, Schima superba, Cunninghamia lanceolata and Fokienia hodginsii in subtropical region of china were selected as the research objects. The mains purpose of this study aims to investigate effects of main afforestation species on gene abundance and community structure of soil nitrogen cycle-related functional microorganisms, and to elucidate the microbial driving mechanism of the effects of subtropical plantation species on soil nitrogen retention. Method: For five kinds of plantation growing on acidic red soil, we applied real-time quantitative PCR to characterize the abundance of nitrogen-fixing microorganisms(ni..
