植物化感作用是自然界普遍存在的一种现象,在农作物耕作、杂草控制、病虫害防治以及林木营造等方面发挥着重要作用。树种搭配是成功营造人工混交林的关键,林木种间的化感作用在混交树种的选择上起着重要作用。文中从化感物质的收集与提取、化感物质的鉴定以及化感作用的表达等方面,对人工混交林常见树种间化感作用的研究情况和成果进行综述,以期为混交林选择树种组合提供科学依据,为生态公益林建设服务。
Plant allelopathy is a common phenomenon in nature and plays an important role in crop cultivation, weed control, pest and disease control, and tree planting. Tree species collocation is the key to successfully creating artificial mixed forest. Allelopathy between species plays an important role in the selection of mixed tree species. In this paper, the researches and allevations of the allelopathic effects of common tree species in mixed plantations are reviewed in the aspects of the collection and extraction of allelochemicals, the identification of allelochemicals and the expression of allelopathic effects, so as to provide scientific basis for selecting tree species combinations for mixed forest Basis for the construction of ecological public welfare forest service.
