摘要:

海藻提取物,特别是海藻寡糖,是使用现代技术从海藻中提取的天然活性物质,随着海藻寡糖在农业领域的应用不断深入,其研究取得了重大进展。为进一步系统了解和应用海藻寡糖,本文讨论了它们的来源、分类和生产方法,总结了海藻寡糖对增强作物抗逆性和抗病性、促进生长发育和改善养分吸收的影响,以及海藻寡糖在各种作物上的应用效果和作用机理。生物法降解海藻多糖是未来海藻寡糖制备的方向,现代生物法一般采用酶降解法,利用褐藻胶裂解酶将褐藻胶降解为褐藻寡糖或是利用琼胶裂解酶将琼胶降解为琼胶寡糖。海藻寡糖在农业中作为植物抗逆和抗病的诱导剂、生物刺激素和肥料增效添加剂使用,海藻寡糖通过调控植物基因表达、酶活性、激素合成和分配等方式增强农作物对干旱、低温、高盐渗透、重金属等胁迫因子的耐受性,并激发植物免疫,提高农作物抗病性。海藻寡糖对植物具有生物刺激作用,可调节植株生长发育,提高其对肥料的吸收效率,从而提升农作物产量和品质。海藻寡糖的应用对中国农业生产的绿色、高效、可持续发展具有积极意义,也有助于海洋资源的充分开发与利用。

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.
