摘要:

氮、磷元素在生物体内的组成及分配是相互联系的整体,可与环境相互作用,调节植物营养水平与生长发育过程。本文综述了环境非生物、生物和人为因子对植物氮、磷元素化学计量特征的影响,氮、磷化学计量对植物生长发育和代谢产物的影响机制,及其对药用植物生长发育和代谢产物积累的作用,并对药用植物的氮磷化学计量研究趋势进行展望。指出氮磷元素化学计量特征为药用植物响应环境变化机制、限制性营养元素判断、探讨与菌根真菌的相互作用等研究提供新思路,为药用植物的资源评价与规范化种植提供理论依据。

Abstract:

Composition and distribution of nitrogen (N) and phosphorus (P) in an organism are interrelated with the environment, and regulates plant nutrition and growth process. In this paper, we review the abiotic, biotic and anthropogenic effects on plant N and P stoichiometry, the influence mechanism of N and P stoichiometry on growth and metabolism of plants, and its effects on the growth, development and metabolite accumulation of medicinal plants. We suggest that N and P stoichiometry could provide new ideas for the research on medicinal plants, including analyzing the growth and metabolism responses of the plants to environmental changes, investigating the interaction between mycorrhizal fungi and the plants, and the identifying limiting nutrient(s). This review could also provide a theoretical basis for scientific planting and resource evaluation of the medicinal plants.
