摘要：根系构型(Root system architecture,RSA)是指植物根系在土壤中的空间分布结构和延展形态。根系构型不仅决定了植物获取水分和养分等资源的能力,还影响到根系其他功能的发挥,对植物整体的健康状况起着决定性作用。研究植物根系构型有助于更好地理解植物的水肥吸收规律、根系与地上部之间的关系,同时对于了解植物的生理健康和生态功能也具有重要意义。因此,本文重点对其形态、功能、可塑性和研究方法等方面的研究进行了综述。文中首先概述了根系的基本结构、生理和生态功能。然后从土壤水分、养分、温度、通气等方面总结了影响根系构型的土壤因素。之后,详细描述了根系构型的研究方法,包括传统挖掘法、二维形态观察法和三维图像重建法等。最后,在此基础上,探讨了未来的发展方向,以期为研究者在该领域进一步开展研究工作提供理论基础。
Root system architecture(RSA) refers to the spatial distribution and extended morphology of plant root systems in soil. RSA not only determines the ability of plants to obtain water and nutrients but also affects other ecological functions. Hence, it plays a dominant role in the overall health of plants. The study of RSA can provide insight into plant absorption of water and fertilizers, the relationship between above-and belowground plant parts,and the physiological health and ecological functions of plants. Therefore, this paper summarizes research on the morphology, functionality, plasticity and research methods of RSA. We first review the basic structure, physiology,and ecological functions of root systems. Then the soil factors that shape RSA—including soil moisture, nutrients,temperature, aeration, and others—are summarized. After that, research methods for studying RSA are described in detail, including harvesting, two-dimensional morphological observation, and three-dimensional image reconstruction. Finally, future research developments and innovations are discussed to provide a theoretical basis for further investigations in this field.
