摘要:

旨在通过综述广藿香连作土传病害的发生及其根际微生态研究进展,为缓解其连作障碍提供理论依据。广藿香的主要土传病害包括由茄科雷尔氏菌(Ralstonia solanacearum)引起的青枯病和尖孢镰刀菌(Fusarium oxoysporum)等引起的根腐病。病原微生物通过破坏根际微生态平衡,抑制广藿香植株生长和发育,降低产量和药用成分含量,影响种植效益。同时,广藿香根系分泌的化感物质可导致土壤酸化、养分失衡等理化性质改变,进一步加剧根际微生物群落结构失调,成为病害发生的关键诱因。土壤中有益微生物可通过竞争、拮抗和诱导抗性等机制抑制病原菌,人工合成菌群的施用可有效缓解连作障碍。近年来,基因组学、代谢组学等多组学研究技术的快速发展,以及人工合成菌群的应用,为土传病害的机制研究和绿色防治提供了新思路。未来研究应重点阐明病原菌致病机制,优化合成菌群应用,构建综合防治体系,为广藿香产业可持续发展提供理论依据和技术支撑。

Abstract:

This article reviewed the occurrence of soil-borne diseases of Pogostemon cablin and research progress on its rhizosphere microecology under continuous cropping, aiming to provide a theoretical basis for alleviating continuous cropping obstacles. The main soil-borne diseases of P. cablin included bacterial wilt incited by Ralstonia solanacearum and root rot caused by Fusarium oxoysporum. Plant pathogens in P. cablin disrupted the rhizosphere microecological balance, inhibiting the growth and development of plants, reducing yield and medicinal compound accumulation, and directly impacting planting benefits. Meanwhile, continuous cropping of P. cablin induced allelochemical release from its roots, triggering soil acidification and nutrient imbalance that restructured rhizosphere microbial community. The imbalance of the rhizosphere microbial community was identified as a pivotal factor driving disease development in continuously cropped P. cablin. Beneficial rhizobacteria suppressed soil-borne pathogens through competitive exclusion, antimicrobial metabolite production, and induced systemic resistance (ISR) mechanisms, whereas synthetic microbial communities (SynComs) supplementation alleviated the occurrence of continuous cropping obstacles. Recent advancements in multi-omics technologies (e.g., genomics, metabolomics) and SynComs have revolutionized soil-borne disease research, offering novel strategies for pathogen control and sustainable agricultural practices. Future research must prioritize clarifying the pathogen pathogenesis mechanisms, optimizing the application of SynComs, and constructing a comprehensive control system to provide theoretical basis and technical support for the sustainable development of the P. cablin industry.
