摘　　要：植物化感作用作为一种自然的生态现象,在自然界中普遍存在。目前对植物化感作用的研究主要集中在化感物质的分离、鉴定、释放途径、作用机理及化感作用对农、林、牧等草地农业生态系统持续发展的应用潜力等方面。但化感作用在草地农业中的具体作用和应用还缺乏深入系统地概述。为探明化感作用在草地农业生态系统的作用,本文从植物化感作用的物质基础出发,概述了化感作用在植物种内、植物种间、植物与昆虫、植物与微生物等作用及其作用机制;进一步对近年来化感作用在农业、沙旱生及草地草原等草地农业生态系统的研究成果进行了综述;最后指出植物化感作用在草地农业中的应用价值,并对其存在的问题进行分析展望。Plant allelopathy,as a natural ecological phenomenon,is common in nature.Current research mainly focuses on separation,identification,releasing mode,operational principle of plant allelopathy,and allelopathy application potential on sustainable development of grassland agroecosystem including agriculture,forestry,and animal husbandry.However,the specific roles and application of allelopathy in grassland agroecosystem are still lack of deep and systematic analysis.In order to understand the roles of allelopathy in grassland agroecosystem,we firstly summarized the allelopathy mechanism in intraspecific,inter-species,plant and insect,plant and microorganism starting from the material basis of plant allelopathy;then reviewed the latest research achievements of allelopathy in grassland agroecosystem including agriculture,sand xerophytic and grassland;finally pointed out the application value of plant allelopathy in grassland agroecosystem as well as its existing problems.
