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.
植物化感作用与许多生态因子相关。土壤养分亏缺会影响植物化感物质的产生,进而影响植物的化感潜力,而植物化感物质可通过络合、吸附、酸溶、竞争、抑制等方式影响土壤养分的形态和水平。本文总结了植物化感物质、植物化感潜力与土壤养分之间的交互作用,并对该领域进一步的研究方向进行了展望。建议应加强以下几个方面:(1)整合植物化感作用与土壤 - 植物营养研究,以更精确、深入地阐释植物化感物质、植物化感潜力与土壤养分之间的关系;(2)整合植物化感作用与生态系统养分循环研究,模拟自然条件下的植物养分扰动,使化感作用研究结果更真实、可靠;(3)开展针对养分过量或污染土壤的化感作用研究,为揭示农林生产中植物相互作用机制及生物量变化以及生态保护提供新思路和科学依据。
