| 摘 要： | 应用红外光谱法和^1H-NMR波谱法初步研究了不同配施化肥处理条件下HA和FA的化学基团组分，并探讨了不同施肥处理对腐殖质化学基团构成的影响。结果表明：不同配施化肥的处理明显影响了土壤腐殖质分子的结构和含量变化。施用化肥有利于HA结构的年轻化、简单化，其影响效果为平衡施化肥（NPK）〉不平衡施化肥（PK）。^1H-NMR研究结果表明不同配施化肥处理FA样品的谱图形态非常相似，出峰位置基本相同。长期平衡施化肥（NPK配施）FA中碳水化合物的H及其它与O、N相连的C上的H的相对含量较高，而长期不施N（施PK）处理FA中烷基链烃中的H相对含量较高。

| Abstract: | Components of chemical groups in soil humic acids(HA) and fulvic soids(FA) isolated from soils different in fertilization treatment were studied with the aid of infrared spectrum(IR) and~(1)H nuclear resonance spectroscopy(NMR),and effects of different fertilization treatments on chemical group structure of the humus were explored.The results show that fertilization affected structure and content of soil humus,and aromatization degree and fraction of simple organic molecules in HA isolated from fertilized soils.The effect was greater in Treatment NPK than in Treatment PK.The~(1)H NMR results show that the relative content of carbonhydrate H of FA is the highest in the treatment of long balanced fertilization(NPK treatment),while the relative content of aliphatic H is higher in Treatment PK. |
