摘要
煤质腐植酸粗略分为腐植酸（ＨＡ）和黄腐酸（ＦＡ）两大类，是芳香稠环缩合程度不同、取代度不同的多取代芳香羧酸混合体，不可能用单一的化学结构表示。煤质腐植酸在农业上有广阔的应用前景，在改良盐碱地上有明显效应，能够促进土壤微生物活动，增加土壤酶活性；应用于化肥可作为缓释剂、包衣剂，可增加肥效，减少挥发，提高化肥利用率；有促进植物呼吸和新陈代谢功能，用来生产各种植物生长调节剂和增糖剂、抗旱剂、抗寒剂等；与农药配合使用有缓释和增效作用；在养殖业中可配制各种饲料添加剂。
This paper described essential composition and properties of humic acid from coal.Some important actions of humic substances from coal were discussed here, including: enhancement effects to chemical fertilizers and pesticides, facilitanting effects of transport and availability to nutrient elements and trace metals, stimulation effects to plant growth and improvement effects to soil, especially saline and alki soil. Humic acids from coal has a very wide using prospect in agricultual field.
