利用造纸黑液木质素，按一定的技术路线，引入Ｎ营养元素，制得含氮量为１５．４７％的氨氧化木素（ＡＯＬ）。本文将ＡＯＬ作为缓释Ｎ肥，在水稻土上与三种等Ｎ量化肥进行玉米的盆栽试验，结果表明：施用ＡＯＬ的处理玉米生物量比碳铵、尿素处理要高；ＡＯＬ与尿素配施处理的玉米生物量比单施尿素效果好，表明ＡＯＬ对尿素有一定增效作用，对土壤脲酶活性的分析发现，施用ＡＯＬ的土壤脲酶活性明显低于对照，说明ＡＯＬ还可以作为脲酶抑制剂施用。
The use of papermaking black liquor lignin, according to a certain technical route, the introduction of N nutrients, nitrogen content of 15.47% ammonia amidulin (AOL). In this paper, AOL as a slow-release N fertilizer, paddy soil with three kinds of equal amount of N fertilizer for corn pot experiments, the results showed that: AOL treatment of corn biomass than ammonium bicarbonate, urea treatment is higher; AOL with urea The results showed that AOL had a certain synergistic effect on urea. Analysis of soil urease activity found that soil urease activity of AOL was significantly lower than that of control, indicating that AOL could also be used as a urease inhibitor .
