合理配施有机肥下根际微生物防控土传病害机理研究进展

Research progress on the mechanism of rhizosphere microorganisms controlling soil-borne diseases under rational application of organic fertilizer

  • 摘要: 土传病害因分布范围广、传播速度快且危害性严重,成为限制作物产质量提高的主要因素。近年来,多组学技术的发展揭示了合理配施有机肥下土壤微生物菌群结构和功能变化及其对土传病害的作用机理,对减少化肥施用和对农药的依赖,促进农业优质绿色发展具有重大意义。本文综述了合理配施有机肥对土传病害的防控效应,分析了合理配施有机肥下根际微生物调控土传病害的结构和功能响应,描述了调控根际微生物的土壤驱动因素,进一步从根际土壤微生物的直接作用、土壤微生物互作以及诱导植物免疫等方面,探究阐述了与根际微生物群落调控相关的抑病机理,探讨与展望了今后合理配施有机肥影响土传病害的重点研究方向,旨在通过施肥管理调控土壤微生物多样性和稳定性,进而促进土壤和植物健康。

     

    Abstract: Soil-borne diseases have become a major factor limiting the improvement of crop yield and quality because of their wide distribution, rapid spread, and server harmfulness. In recent years, advances in multi-omics technologies have shed light on the changes of soil microbial community structure and function under rational application of organic fertilizers, as well as their mechanisms of inhibiting soil-borne diseases. These insights are of great significance to reduce chemical fertilizers and pesticides application and promote the agricultural green development. This paper reviewed the prevention and control effects of organic fertilizer application on soil borne diseases, analyzed the structural and functional responses of rhizosphere microorganisms in regulating soil borne diseases under such conditions, and described the soil driving factors of regulating rhizosphere microorganisms. Furthermore, the inhibition mechanisms related to rhizosphere microorganisms on soil-borne disease were summarized from the aspects such as the direct effects of rhizosphere soil microorganisms, soil microbial interactions, and induction of plant immunity. The article also discusses and outlines key future research directions on the impact of rational application of organic fertilizers on soil-borne diseases, aiming to regulate soil microbial diversity and stability through fertilization management, thereby promoting soil and plant health.
