摘要:

辣椒作为全球重要的经济作物,常受到枯萎病、疫病、炭疽病、根腐病等土传真菌病害的严重威胁。传统化学防治不仅会引发病原菌抗药性,还可能导致环境污染,因此生物防治成为植物保护领域的重要发展方向。木霉属真菌是高效的生防微生物,其防治潜力已得到广泛证实。本文中系统综述了木霉菌的分类、防治效果、作用机制及菌剂研发进展,并总结了其在防控辣椒土传真菌病害调控中的作用,主要包括以下方面:重寄生作用(通过识别病原菌信号,分泌几丁质酶、葡聚糖酶等降解酶破坏菌丝结构);竞争作用(依赖快速定殖能力抢占生态位);抗生作用(产生如6-戊基-2H-吡喃-2-酮、胶霉毒素等次级代谢产物抑制病原菌生长);诱导系统抗性(激活植物茉莉酸、水杨酸信号通路,增强防御酶活性);协同拮抗作用(与有益细菌、真菌联合抑制病原菌并改善土壤微生态);以及促生作用(分泌植物激素如生长素、赤霉素等,提高养分利用率)。未来研究应深入解析木霉—植物—病原菌的互作机制,优化菌剂制备工艺与施用策略,以促进木霉菌在辣椒病害绿色防控中的规模化高效应用。

Abstract:

As a globally important economic crop,chili peppers are severely threatened by soil-borne fungal diseases such as Fusarium wilt,Phytophthora blight,anthracnose,and root rot. Traditional chemical control not only induces resistance in pathogenic fungi but also causes environmental pollution,biological control technology to become an important development direction in the field of plant protection. Fungi of the genus Trichoderma,as efficient biocontrol microorganisms,have been fully proven to possess great biocontrol potential. This paper systematically reviews the classification,biocontrol efficacy,mechanisms of action,and research and development progress of Trichoderma-based formulations,and summarizes its mechanisms in controlling soil-borne fungal diseases of chili pepper,mainly including:1) Hyperparasitism(recognizing pathogen signals and secreting degrading enzymes such as chitinase and glucanase to destroy mycelial structures);2)Competitive action(occupying ecological niches relying on rapid colonization ability);3)Antibiosis(producing secondary metabolites such as 6-PP and gliotoxin to inhibit pathogen growth);4)Induced systemic resistance(activating plant jasmonic acid and salicylic acid signaling pathways to enhance the activity of defense enzymes);5)Synergistic antagonism(combining with beneficial bacteria and fungi to inhibit pathogens and improve soil microecology);6)Growth-promoting effect(secreting plant hormones such as auxin and gibberellin to improve nutrient utilization efficiency). Future research should further explore the interaction mechanisms among Trichoderma,plants,and pathogens,optimize the preparation process and application strategies of microbial agents,so as to promote the large-scale and efficient application of Trichoderma in the green prevention and control of chili pepper diseases.
