腐植酸保水剂的研发现状与发展趋势

Current Research and Future Development of Superabsorbent with Humic Acid

近年来,腐植酸保水剂受到了人们的广泛关注,由于它既有保水性能又具有赋肥作用,已在农业、园艺等领域得到了实际应用。腐植酸分子中含有多种功能基团,是一种低成本、多功能的物质,它能调控植物生长,加速根系发育,改善土壤的团粒结构,有益于营养元素的吸收,将它与烯类单体共聚可制备腐植酸保水剂。文章从吸水、保水赋肥等方面综述了腐植酸保水剂的研究和应用现状,并展望了未来的发展趋势。

In recent years, superabsorbent with humic acid have been applied practically in agricultural and horticultural fields because of its advantages of water retention capacity and fertilizer function. Humic acid, consisted of various functional groups, is a low-cost, multifunctional fertilizer, which can regulate plant growth, accelerate roots development, improve soil cluster structures and benefit nutrients absorption. The superabsorbent was produced by polymerization of humic acid and vinyl monomers. From the viewpoints of water absorbency, water retention, fertilizer function, and its application, this article reviewed the progress of superabsorbent with humic acid, and proposed the future research directions.
