棉花秸秆的应用研究进展

Research progress in the application of cotton straw

棉花秸秆(棉秆)是棉花生产的副产物,是1种重要的可再生性生物质资源,其综合利用研究对于优化能源结构和实现“双碳”战略目标具有重要意义。由于结构上的差异,玉米、小麦、水稻等秸秆的成功利用方式难以在棉秆上直接重现,而传统的棉秆处理和应用方式会造成资源浪费和环境污染,因此加强棉秆的综合利用研究在提升农业废弃物利用率、改善能源结构、降低环境污染等方面具有重要作用。从提高棉秆综合利用效率的角度出发,介绍了棉秆在还田、饲料化、能源化、基料化、原料化等方面的利用模式,并对未来的发展方向进行了展望,为棉秆的多元化利用提供方法参考和研究思路。

Cotton straw is a by-product of cotton production and an important renewable biomass resource,and the study on its comprehensive utilization is of great significance to optimize energy structure and achieve'dual carbon'goals.Due to the structural differences,the successful application methods of corn,wheat,and rice straw cannot be directly applied to cotton straw.Traditional treatment and application of cotton straw cause resource waste and environmental pollution.Therefore,it is essential to enhance the comprehensive utilization of cotton straw to improve agricultural waste utilization efficiency,optimize energy structure,and reduce environmental pollution.From the perspective of enhancing the comprehensive utilization efficiency of cotton straw,this article summarizes various utilization modes,including straw returning to the field,using them as feed,energy substrate,and raw material,and prospects the future multiuse of cotton straw which will provide methodological reference and research ideas for the diversified utilization of cotton straw.
