摘  要：
海藻寡糖是海藻多糖经过降解得到的一系列寡糖片段,分子量低、水溶性好,具有广泛的生物活性优势,在农业生产中具有广阔的应用前景。文章对近年来海藻寡糖在土壤修复和促进植物生长两方面的研究进展进行综述,同时指出海藻寡糖对土壤重金属的不同作用效果限制了其在土壤修复中的进一步应用、土壤微生物对海藻寡糖—重金属络合物的影响机理不明及海藻寡糖作为植物诱导剂在实际应用中存在局限性等问题。因此,今后在海藻寡糖的利用中应注意以下问题:进行土壤修复时,应针对土壤的酸碱度及重金属污染情况,合理选择海藻寡糖的施用量,确定适宜的修复方式;可将海藻寡糖与其他诱导剂或杀菌剂联合使用以解决其作为诱导剂的局限性;此外,海藻寡糖可作为新型肥料添加剂进行深入开发,以促进其在农业领域的进一步应用。

摘  要：
Seaweed oligosaccharides degraded from the seaweed polysaccharides are a series of oligosaccharide fragments. Seaweed oligosaccharides are characterized by lower molecular weight, better solubility, lots of biological activities, compared with seaweed polysaccharides, thus they has a broad application prospest in agricultural production. The present study was conducted to summarize research advances in the application of seaweed oligosaccharides in remediation of contaminated soil and promotion of plant growth, and discussed several problems of application of seaweed oligosaccharides. It was found that the application of seaweed oligosaccharides in soil remediation was restricted due to the opposite effects of seaweed oligosaccharides on heavy metals in soil. The mechanism of soil microorganisms on the seaweed oligosaccharides and heavy metals complex was still not clear. There were limitations in the pratical application of seaweed oligosaccharides as plant resistance inducer. Therefore, the application of seaweed oligosaccharides should be focused on in future, as follows: the reasonable dosage of seaweed oligosaccharides and the appropriate way of remediation will be determined by the soil p H value and heavy metal contaminations degree. Meanwhile, seaweed oligosaccharides will be used in combination with other inducers or fungicides to overcome the limitations. Furthermore, seaweed oligosaccharides can also be used as new fertilizer additives to promote their further application in agriculture.
