大豆根际微生物的研究进展

Research Progress on Soybean Rhizosphere Microorganisms

根际微生物组被称为植物的“第二基因组”,在植物生长、发育和健康等方面发挥了重要作用。微生物在大豆根系土壤营养元素循环过程中起着十分关键的作用,即大豆根际土壤微生物可直接或间接地影响大豆的生长健康、营养物质吸收及病害防治等,大豆的生长也对土壤微生物的群落结构产生重要影响。本文主要针对近些年来关于大豆根际土壤微生物多样性及结构变化情况进行概述,主要包括不同的大豆种质、耕作栽培方式、生长时期、根际分泌物以及外界处理等条件下大豆根际土壤微生物的群落结构变化,以及大豆根际微生物与土传病害的关系,同时对未来关于大豆根际微生物的相关研究等方面提出建议与展望。

The rhizosphere microbiome is known as the‘second genome’of plants and plays an important role in plant growth,development and health.Microorganisms play a crucial role in the nutrient cycling process of soybean root soil by directly or indirectly affect the growth and health of soybeans,nutrient absorption,and disease prevention and control.The growth of soybean also strongly affects the community structure of soil microorganisms.This review primarily summarizes recent advancements regarding changes in diversity and structure of soybean rhizosphere soil microorganisms under various conditions such as different germplasms,cultivation methods,growth stages,rhizosphere secretions and external treatments.Additionally explored is the relationship between soybean rhizosphere microorganisms and soil-borne diseases.Furthermore,suggestions for future research on soybean rhizosphere microorganisms are provided.
