| 摘 要： | 介绍磷酸二铵和尿素2种化学肥料的特性,从农作物吸收铵态氮和酰胺态氮的原理、添加尿素对磷酸二铵生产工艺的影响、选择尿素添加方式等3方面分析提高磷酸二铵产品中总氮含量的可行性,并质疑GB/T10209.1—2008总氮含量测定方法不能测出尿素所增加的氮,故建议修订相关国标。

| Abstract: | The chemical fertilizer properties both DAP and urea are introduced. Based on the three aspects including the principle of absorbing ammonium nitrogen and amide nitrogen for crop, the effect of adding urea to DAP production process, and the adding urea mode, the feasibility of increasing total nitrogen content is analyzed. For the problem that the N in adding urea can＇t be determined by the method ofGB/T 10209.1-2008, suggest correcting the national standard. |
