摘　　要：土壤盐碱化被视为限制全球土壤生产力、粮食安全和生态系统的重要因素,全球有大面积的盐碱地,因而又是最重要的边际土地资源。近年来,生物炭在改良土壤结构、提高土壤肥力以及固碳减排等诸多领域中表现出极大的应用潜力。研究表明,生物炭的施用能够改善盐碱地土壤理化性质、提高碳含量和促进植物生长,可作为盐碱地改良的有效措施使用。然而,生物炭对盐碱地土壤改良和对植物生长的影响机理较为复杂,有待深入的研究。本文梳理了当前国内外生物炭改良盐碱地土壤结构、化学性质、养分有效性、生物活性的效果及其对植物生长影响的研究进展,在系统分析生物炭改良盐碱地土壤的机制基础上,对生物炭改良盐碱地的应用潜力进行了展望,以期为生物炭在盐碱地改良上的高效利用提供参考。Soil salinization is considered the most important degraded soils that limit soil productivity,food security and ecosystems worldwide.There are a large area of saline-alkaline soils in the world,so they are the most important marginal land resources.In recent years,biochar has shown great application potential in soil structure improvement,soil fertility improvement,carbon sequestration and emission reduction.Recent studies have shown that the application of biochar can improve soil physical and chemical properties,carbon content and promote plant growth,and can be used as an effective measure for saline-alkaline land improvement.However,the effects of biochar on saline-alkali soil improvement and plant growth are complex and need to be further studied and summarized.Therefore,the effects of biochar on physicochemical properties,nutrient utilization,soil biological activity and plant growth in saline-alkaline soil were reviewed and discussed in this paper.Additionally,the improvement effect and its possible mechanisms for biochar on saline-alkaline soil and potential mechanisms of improvement on plant growth were systematically analyzed and summarized.This review would provide a reference for the applying biochar in saline-alkaline soil’s improvement and efficient utilization.
