Abstract:

The extensive use of fertilizers and pesticides in China has impeded the development of green agriculture. Seaweed oligosaccharides can promote sustainable green agriculture, enhance agricultural production efficiency, and ensure food safety. This study presented a comprehensive overview of seaweed oligosaccharides, including their classification, preparation techniques and agricultural applications. First, the classification and structure of seaweed oligosaccharides were outlined. Next, the physical, chemical and biological preparation methods of seaweed oligosaccharides were discussed in detail. The applications of seaweed oligosaccharides in improving fertilizer utilization, soil fertility, crop yield and quality, and disease resistance were then explored. The results demonstrated that seaweed oligosaccharides had the agricultural functions in fertilizer utilization, crop yield and quality and disease resistance enhancement. Finally, the future prospects of applying seaweed oligosaccharides in agricultural production were put forward, providing valuable insights to further promote their role in achieving green agriculture development.

Key words: seaweed oligosaccharides, oligosaccharide preparation, oligosaccharide benefits, yield enhancement and quality improvement, green agriculture
