摘要
植物根系构型即根系在其生长介质中的生长与分布,直接影响着植物的生长和发育.通过概述植物根系构型的基本概念以及生态作用,总结影响植物根构型的诸多因素,主要包括根系的生物学特性、自然条件和人工干扰.基于当前的研究现状,提出了植物根系构型需进一步研究的问题.
Plant root architecture,i.e, the growth and spatial distribution of roots in the growth medium,affects the plant＇s growth and development directly. The article summarizes the basic concept, and the ecological roles of plant root architecture, and generalizes the influencing factors, mainly including the biology of plant roots, natural conditions and human interference. Based on the current status of research on the root architecture,the paper offers some issues which require further study in the future.
