摘　　要：木霉菌是重要的植物病害生物防治菌,该文在简要介绍木霉菌及其生防机制的基础上,综述了木霉与病原菌的互作关系,通过对营养和空间的竞争来抑制病原真菌的生长和繁殖,木霉菌对病原真菌的重寄生机制、木霉菌产生抗生素抑制或杀死病原真菌的抗生机制、以及木霉菌促进植物生长诱导植物系统抗病性机制等几方面阐述了木霉的生物防治机制,以期为全面了解木霉对植物真菌病害生物防治机制提供理论指导。Trichoderma spp. is an effective bio-control agent for controlling fungal plant pathogen. On the basis of a brief introduction of Trichoderma and its bio-eontrol mechanism, the interaction between Trichoderma and pathogens was summarized. Through the competition for nutrients and space, the growth and propagation of pathogens were inhibited, the hyperparasitism of Trichoderma spp. to pathogenic fungi, Trichoderrna spp. produced antibiotics to inhibit or kill pathogenic fungi, Trichoderma spp. promoted plant growth and induced plant systemic resistance responses, etc,in order to provide a theoretical guidance for the role of Trichoderma spp. in biological control mechanisms for plant fungus diseases.
