生物有机肥对熏蒸土壤氮转化微生物驱动机制的研究进展
Research Progress on the Microbial Driving Mechanisms of Nitrogen Transformation in Fumigated Soil Amended with Bio-organic Fertilizer
摘要
Abstract
Soil fumigation is one of the effective measures for controlling soil-borne diseases associated with continuous crop-ping obstacles.However,its broad-spectrum biocidal properties not only eliminate pathogens but also severely disturb microbial commu-nities involved in nitrogen transformation,thereby hindering the conversion of nitrogen forms in soil.Bio-organic fertilizer can acceler-ate the reconstruction of soil microecology after fumigation,but its underlying driving mechanisms remain unclear.As a key mediator through which plants regulate the rhizosphere microbiome,root exudates provide a new perspective for elucidating this mechanism be-cause specific components can selectively recruit functional microorganisms.Based on literatures of the effects of soil fumigants on mi-crobial communities and nitrogen-transformation functional microorganisms,as well as the restorative effects of bio-organic fertilizer on the microecology of fumigated soil,this paper summarizes the regulatory mechanisms by which bio-organic fertilizer drives nitrogen transformation in fumigated soil from the perspectives of the basic driving role of carbon and nitrogen substrates in organic materials,syn-ergistic regulation of the rhizosphere microecology,the mediating role of root exudates in microbial reconstruction in fumigated soil,and the differential response patterns of nitrogen-transformation functional microbial communities.This review aims to provide a reference for investigating the microbial reassembly mechanisms by which bio-organic fertilizer drives nitrogen transformation in fumigated soil.关键词
