植物幼苗能否在盐碱地定植成功是种群建立、维持发展的关键环节。研究表明,盐碱胁迫下成体植物对同种植物幼苗的定植有重要促进作用,目前对其解释主要围绕地上部分形成的冠层效应展开的,而对根际效应的研究较少,本文阐述成体植物地上部分和地下部分对同种幼苗的生长发育资源权衡分配策略,分析成体植物是如何通过根际资源的重分配来“保护”同种植物幼苗的生长发育;分析成体植物根际因子对同种幼苗的影响。揭示成体植物根际对幼苗“保护”的根际机理及丛枝菌根的作用,对加深认识植物种内相互作用机制和指导盐碱胁迫下种群的建立都有重要意义。
The plant seedlings that can successfully grow up in saline-alkali land are crucial progress for popu-lation establishment and maintaining development. Studies have shown that adult plants under salt-alkali stress play an important role in promoting the survival rate of seedlings of the same spe-cies. Currently, account for the phenomenon mainly revolves around the canopy effect formed by the above-ground part, but there are few studies on the rhizosphere effect. This study elucidates the aboveground and underground allocation strategy for the growth and development resources of the same species of seedlings in the aerial and underground parts, analyzes how adult plants “protect” the growth and development of seedlings of the same species through redistribution of rhizosphere resources, describes the effect of adult plant rhizosphere factors on the seedlings of the same spe-cies, reveals the rhizospheric mechanism of the adult plant rhizosphere on the “protection” of the seedlings of the same species and the effect of arbuscular mycorrhizal. It is of great significance to deepen the understanding of the interaction mechanism of plant species and guide the establish-ment of populations under salt-alkali stress.
