| 摘 要： | 盐地碱蓬是盐碱地先锋植物,是目前能在含盐量为3%的土壤中生存的极少数植物之一,是重要的耐盐种质资源。其在植物耐逆机理、耐盐基因的开发利用以及土壤生态修复等方面具有极为重要的应用潜力。为了全面的了解盐地碱蓬的耐盐机理以及改良土壤的机理,本研究分别从形态学、生理生化层面以及分子水平等方面对其耐盐机理进行总结,并就盐地碱蓬影响土壤理化性质、微生物、土壤养分以及在土壤重金属、有机污染物治理等方面的研究进展进行梳理。在此基础上提出研究展望,认为应更多的关注盐地碱蓬耐逆关键基因的挖掘利用、盐地碱蓬在盐碱地植物群落演替过程的作用以及盐地碱蓬与微生物如何共同改良土壤的机理。

| Abstract: | As one of the pioneer plant in salt soil, Suaeda salsa can survive in soil with 3% salt content, which is an important germplasm resource, and has a crucial application potential in the research of plant resistance mechanism, development and utilization of salt-tolerant genes and soil ecological remediation. To fully understand the salt tolerance mechanism of Suaeda salsa and its mechanism of soil improvement, from the aspects of morphology, physiology and biochemistry and molecular level, we summarize its salt tolerance mechanism, discuss its effect on salt alkaline soil physical and chemical properties, microbial species and refinement of soil nutrients, and review the research on its role in controlling soil heavy metals and organic pollutants. Based on the study, we argue that more attention should be paid to the key salt tolerance gene of Suaeda salsa, its role in plant community succession process, and the combined mechanism of Suaeda salsa and microbial species on soil improvement. |
