土壤多糖的研究进展

土壤多糖是土壤中碳水化合物的主要存在形式，是土壤中一种重要的有机胶结物质，国内外对土壤多糖的研究涉及众多方面，本文从土壤多糖的来源、组成、含量及分布；土壤多糖的化学结构；土壤多糖的稳定性、对土壤结构形成的作用以及在肥力上的意义等方面进行了梳理和总结，为土壤多糖的深入研究提供借鉴。

The Research Progress of Soil Polysaccharide

Soil polysaccharide is the main form of the carbohydrates in the soil, it is one of the most important organic cementing materials. From the source, composition, content and distribution of soil polysaccharide, the chemical structure of soil polysaccharide, the stability of soil polysaccharide, the role of soil polysaccharide on soil structure formation and the meaning of soil fertility and so on were studied. Soil polysaccharide of extrac?tion and determination methods, physical and chemical properties, soil aggregate and micro aggregate forma?tion and the modified mechanism of the role of soil structure remains to be further in-depth study.
