Abstract:

China faces significant challenges of large population and limited arable land resources. In recent years, extreme weather events and ongoing soil degradation have significantly influenced China's agricultural production. With advances in agricultural science and technology, incorporating new materials into agricultural practices has been proven to be an effective strategy for adapting to these developments and environmental shifts. Seaweed extract, specifically seaweed oligosaccharides, are natural active substances derived from seaweed using modern technology. They are employed in agriculture as inducers for plant stress and disease resistance, biostimulants, and fertilizer enhancers. With continuous research progresses on the potential applications of seaweed oligosaccharides in agriculture, significant advancements have been achieved in their study and use. To further systematically understand and apply seaweed oligosaccharides, this paper discussed their sources, classification, and production methods. It summarized their impact on bolstering crop stress and disease resistance, fostering growth and development, and improving nutrient absorption, as well as their effectiveness and mechanisms across various crops. This provided innovative approaches and tools for the sustainable and efficient development of Chinese agriculture in the current context.

Key words: seaweed oligosaccharides, bioactive substances, stress resistance, plant growth regulation, fertilizer synergist
