摘要: 土壤-植物系统是生物圈的基本结构单元,土壤与植物之间存在密切的相互反馈。土壤退化导致植物面临各种非生物胁迫,植物的生理代谢遭到干扰,养分获取受到抑制。蚯蚓被称为“生态系统的工程师”。蚯蚓能够通过调控土壤物理-化学-生物学特性,改良退化土壤(盐碱土、重金属和有机污染物污染土壤),缓解植物所受胁迫,增加土壤养分有效性,促进植物生长,并通过自身分泌的信号物质提高植物的抗逆性。蚯蚓对土壤-植物系统的生态修复作用,对于改善植物生长环境、维持土壤生态系统健康和稳定具有重要意义。

Abstract: Soil-plant system is the basic structural unit of the biosphere, with close mutual feedback between soil and plants. The degradation of soil exerts various abiotic stresses to plants, disturbs the physiological metabolism of plants, and inhibits nutrient acquisition. Earthworms are known as “ecosystem engineers”, which can regulate soil physical-chemical-biological characteristics, improve the quality of the degraded soil (saline soil, heavy metals and organic pollutants contaminated soil), alleviate plants under stress, increase soil nutrient availability, promote plant growth. Furthermore, through the secretion of signal substances, earthworms could improve the resistance of plants. The ecological remediation effects of earthworms on soil-plant system are of great significance for improving environment of plant growth and maintaining the health and stability of soil.

Key words: earthworm, saline soil, acidified soil, contaminated soil, plant resistance
