农药作用下的根际微生物相对丰度变化研究进展

Research Progress on the Changes of Rhizosphere Microbial Diversity Under the Action of Pesticides

在我国农业生产中,农药残留一直是一个难以解决的问题。农药残留会给人类身体、农业用地以及其他生物类群带来不良影响。根际微生物作为植物根际土壤中物质交换和能量流动的重要生物类群,研究农药对其多样性的影响十分必要。研究发现:农药作用下的根际微生物多样性主要与农药适应性微生物的数量、农药种类、农药作用机制、农药半衰期、农药施用方式以及施用时间长短有关。此外,研究发现根际微生物还能直接或间接地应用于农残处理中。该文根据相关研究为土壤环境微生物多样性保护、农业用地保护、农产品生产及农残处理提供了新的思路。

In China's agricultural production,pesticide residue is always a difficult problem to solve.Pesticide residues often have adverse effects on humans themselves,agricultural land,and other living groups.As an important biological group of material exchange and energy flow in plant rhizosphere soils,rhizosphere microorganisms is very important to study the influence of pesticides on their diversity.It is found that the rhizosphere microbial diversity under the action of pesticides is mainly related to the number of pesticide adaptive microorganisms,pesticide species,pesticide mechanism of action,pesticide half-life,pesticide application mode and the length of application time.In addition,rhizosphere microorganisms can be directly or indirectly applied to disposal of agricultural residues.According to the relevant research,this paper provides new ideas for the protection of soil environment microbial diversity,agricultural land protection,agricultural production and agricultural residue treatment.
