Abstract: Allelopathy is a phenomenon that plants interact with each other,which widely exists in nature. Allelopathy plays an important role in the succession of natural vegetation and human production activities,thus it is a hot issue in studying farmland,grassland,forest and desert ecosystems. This paper summarizes the recent research results of allelopathy by scholars at home and abroad,introduces the development history of allelopathy,classification and release ways of allelochemicals,sum up the mechanism of allelopathy in detail,and expounds the research significance and practical application of allelopathy from three aspects of agricultural activities,vegetation succession and grass production. On this basis,the paper discusses existing issues in this field,and prospects the future research direction.

Key words: allelopathy of plants, allelochemicals, mechanism of action, practical application
