摘要
腐殖酸广泛存在于自然中,其含有多种功能基,具有很高的反应活性,能与环境中的金属离子及有毒活性污染物等发生相互作用,使其毒性降低。腐殖酸对于土壤保蓄养分、结构改善,酸碱度调节,营养元素平衡等方面都起着至关重要的作用,着重探讨了腐殖酸在农业和生态环境中的应用。
Humic acid widely exists in the nature. Due to a variety of functional groups with very high reactivity, humic acid can react with metal ions and toxic pollutants in the environments, and then reduce the toxicity. Humic acid plays an important role on keeping soil nutrient, improving structure, regulating the pH value, maintaining nutritional balance, and so on. The paper emphasize on humic acid application in agriculture and eco-environment.
