摘　　要：腐殖酸作为尿素增效剂可以提高尿素的利用率,从而增加农作物的产量,本文对腐殖酸尿素的制造方法及其增产机理作了系统的综述,并提出由小粒径腐殖酸制成的腐殖酸尿素是今后腐殖酸尿素的发展方向。Humic acid used as a synergist of urea can enhance utilization rate of urea,consequently increases crop yield. In present review, the recent situation of urea humic acid (UHA) and mechanism in increasing crop yield of UHA are discussed.On the basis of new knowledge of pant physiology, urea humic acid made from smaller humic acid is a promising aspect in research on UHA.
