摘　　要：以尿素为对照,研究了基于新型环保型脲酶抑制剂煤炭腐植酸为原料,采用不同加工方法制成的4种长效腐植酸尿素Ⅰ、Ⅱ、Ⅲ、Ⅳ(UHAⅠ、UHAⅡ、UHAⅢ、UHAⅣ)对玉米产量及品质的影响。结果表明:在本试验条件下,UHAⅠ、UHAⅡ、UHAⅢ、UHAⅣ均可以抑制土壤脲酶活性,提高玉米的产量,改善玉米的品质。其中,UHAⅢ在玉米上的应用效果最佳,能够使玉米增产35 3%。Study of effect of 4 kinds of new humic acid urea on yield and quality of maize was conducted. These new humic acid urea was made of the environmental-friendly urease inhibitor and urea through different producing methods. The results of this experiment showed that in the condition of this experiment, all UHAⅠ、UHAⅡ、UHAⅢ、UHAⅣ inhibited urease activity in soil and increase yield and improve quality of maize, especially UHAⅢ that increased yield of maize by 35.3%.
