腐殖酸-金属络合物在土壤形成和植物营养等方面具有重要的作用。六十年代以来,这方面的研究日益增多。锌是植物所需的微量元素之一,在土壤中常以络合态存在。因此,以络合态存在的锌的数量及其稳定性对土壤的供锌能力将有较大的影响。不少研究 Humic acid-metal complexes play an important role in soil formation and plant nutrition. Since the 1960s, there has been an increasing number of studies in this area. Zinc is one of the trace elements required by plants, often in the soil complexed state exists. Therefore, the amount of Zn present in the complexed state and its stability will have a greater impact on the ability of zinc to feed the soil. A lot of research
