摘　　要：农业废弃物的高值化利用有助于缓解资源约束、减少环境污染。秸秆纤维素是细胞壁中最主要的物质,与木质素和半纤维素稳定嵌套,难以分离。因此,秸秆有效组分分离提取是实现其高值化利用的基础和关键。本文对秸秆中纤维微观结构、形成机制及理化性质进行深入阐述,介绍了提取纤维素的多种技术,并对纤维素分离原理与优缺点进行了凝练。针对现有技术壁垒及局限性,展望秸秆纤维分离、提取及纯化等的研究领域和发展方向,以期为探索出高效绿色环保的工艺技术,实现秸秆纤维素的高值化利用奠定基础。The high-value utilization of agricultural waste can help to alleviate resource constraints and reduce environmental pollution.Cellulose is the most dominant substance in the cell walls of straw,which is stably nested within lignin and hemicellulose and is difficult to separate.Therefore,the separation and extraction of effective components of straw are key to achieving its high-value utilization.In this study,first,the microstructure,formation mechanism,and physicochemical properties of fibers in straw are elaborated in depth;second,various technologies for cellulose extraction are introduced and the principle of cellulose separation and advantages and disadvantages of cellulose separation are condensed;finally,in view of the existing technological barriers and limitations,we look ahead to the research field and development direction of the separation,extraction,and purification of straw fibers with the aim of exploring efficient and green techniques.Finally,the research areas and development directions of straw fiber separation,extraction,and purification are anticipated in view of the existing technological barriers and limitations,with a view to laying a foundation for exploring efficient and green technology and achieving high-value utilization of straw cellulose.
