解淀粉芽孢杆菌对植物土传病害的作用机制

Mechanism of Bacillus amyloliquefaciens on plant soil-borne disease

土传病害已成为限制中国农业可持续发展的主要原因,随着人们对于食品安全和环境保护的重视,生物防治已成为当前国内外防治土传病害的研究热点。解淀粉芽孢杆菌是一种具有广谱抗真菌、细菌活性的生防菌,对植物土传病害有抑制作用。从拮抗作用、促生作用、竞争作用和诱导抗性方面对解淀粉芽孢杆菌的生防机制进行综述,并阐述了存在的问题及今后的发展方向。

Plant soil-borne disease has become the main reason to limit the sustainable development of agriculture in China.With peo⁃ple's attention to food safety and environmental protection,biological control has become a research hotspot in the prevention and treat⁃ment of soil-borne diseases at home and abroad.Bacillus amyloliquefaciens is a kind of biocontrol bacteria with broad spectrum of anti⁃fungal and bacterial activities,which can inhibit soil-borne plant diseases.In this paper,the biological control mechanism of Bacillus amyloliquefaciens was reviewed from the aspects of antagonism,growth promotion,competition and resistance induction,and the exist⁃ing problems and the development direction in the future were expounded.
