摘　　要：植物化感作用与许多生态因子有关.土壤养分缺乏,影响着许多植物化感物质的产生,从而影响植物的化感潜力;反过来,植物化感物质也通过络合、吸附、酸溶解、竞争、抑制等方式影响土壤的养分形态和水平.本文总结了植物化感物质及化感潜力与土壤养分的相互影响,并提出了今后该领域值得进一步研究的问题.包括以下几方面加强植物化感研究与土壤-植物营养学研究的结合,以更深入地阐明植物化感物质、化感作用与土壤养分变化的关系;加强植物化感研究与生态系统养分循环研究的结合,以类似自然(nature-like)的方式模拟自然界植物所受的养分干扰,使养分干扰的化感研究结果更加逼真、可靠;加强对养分过量及受污染时植物化感作用的研究,为揭示农业和林业生产中植物的相互作用机制和生物量变化机制提供新的思路,为生态保护提供科学依据.Plant allelopathy relates to many ecological factors. The deficit of soil nutrients can influence the production of plant allelochemicals, and thus, influence plant allelopathic potential, while plant allelochemicals can influence the form and level of soil nutrients by the ways of complexation, adsorption, acid dissolution, competition, inhibition, and others. In this paper, the interactive effects between plant allelochemicals, plant allelopathic potential and soil nutrients were summarized, and further research aspects in this field were prospected. It was suggested that following aspects should be strengthened： 1 ） the integration of plant allelopathy and soil-plant nutrition research to more precisely and deeply interpret the relationships between plant allelochemicals, plant allelopathic potential and soil nutrients, 2） the integration of plant allelopathy and ecosystem nutrient cycling research to simulate the plant nutrients disturbance in nature and make the allelopathy research results more true and more reliable, and 3） the allelopathy research with soils containing excessive nutrients or polluted to provide new ideas and scientific basis in revealing the mechanisms of plants interaction and biomass variation in agricultural and forestry production, and in ecological protection.
