摘要: 对化感作用在生态学、林业、农业等领域的理论及实践意义进行综述与探讨,并分析了其今后的发展方向.化感作用有助于更加合理地解释生态系统中植物组成与分布、群落演替、协同进化和生物入侵等现象;在林业生产的森林更新、混交林培育中有时会起到决定性作用;在农业上,单作、轮作、覆盖等各种种植方式均受化感影响,此外,一些化感物质可用作杀虫剂和除草剂,从而减轻对环境的污染水体中同样存在化感作用.培育新的抗虫害、抑草品种,分离、鉴定新的化感物质,深入揭示化感作用的机制,是今后化感作用的研究重点.

Abstract: The research significance and foreground of allelopathy concerning ecology,fores try and agriculture were reviewed and analyzed.Allelopathy helps to elucidate th e phenomena such as the composition and distribution of plants,the succession of community,coevolution and invasions of exotic plants in the ecosystem.Sometimes it is crucial to regeneration failure and the establishment of mixed forests.In agriculture,it influences the monoculture, crop rotation,crop cover and so on.S ome allelochemicals can be used as pesticides and herbicides which consequently reduce the environment pollution.Allelopathy exists in aquatic plants,too.Futur e work mainly focus on the cultivation of new allelopathic plants which can avoi d pests and suppress weeds,the isolation and identification of new allelochemica ls as well as intensive study of the mechanism of allelopathy.
