木霉(Trichoderma spp.)对植物土传病害生防机制的研究进展

应用木霉防治植物土传病害已经成为目前生物防治研究的热点。随着分子生物学与生物工程等技术的不断发展,对木霉防治病原微生物的生防机制研究已经取得较大的进展。本文主要从竞争作用、重寄生作用、抗生作用、诱导抗性、促生作用、协同拮抗等方面对木霉的生防机制进行综述,并阐述了防病的分子机理,以期使木霉更加合理地应用到土传病害防治领域中。同时,文章也对木霉的实际应用与可能出现的问题进行分析,并对今后的研究工作进行展望。

Biocontrol Mechanism of Trichoderma spp. Against Soilborn Plant Disease

The application of Trichoderma on controlling soil-borne plant diseases has become a hot topic in the current research of biological control.With the continuous development of molecular biology and bioengineering technology,the research on the biocontrol mechanism of control pathogenic microorganisms by Trichoderma has achieved great success.In this paper,the biocontrol mechanisms of Trichoderma were discussed from the aspects of competition,parasitism,antibiotic action,induced resistance,promoting growth and synergistic antagonism,the molecular mechanism was also described.Aiming at making Trichoderma more reasonable applicated in the field of biological control,the practical application of Trichoderma and possible problems have been analyzed at the same time,and the future research prospect has been carried out.
