硝态氮分子式:CAS号:性质:以硝酸根离子NO3—形态存在于土壤、植物和肥料中的氮素。常用符号NO3——N表示。硝酸钠、硝酸钙、硝酸铵(除含硝态氮外,还含有铵态氮,因其性质更接近硝态氮肥,故归入之)都属于硝态氮肥。淹水的水稻田中硝态氮含量很少,而在温带旱作土壤中硝态氮常有积累。它是植物直接吸收利用的速效性氮素。土壤中硝态氮含量随季节和植物的不同生育期而变。土壤硝态氮不被土壤吸附,雨季易淋失,水田中还可因反硝化作用而损失。植物中的硝态氮是植物体内主要的无机态氮,在一定范围内植物中的硝态氮含量可反映当时土壤供氮状况和植物体内氮素营养水平。但水稻体内所含硝态氮极少,不能作为氮素营养水平和诊断指标。植物组织液中硝态氮的含量(以N计)约为100~1000mg/kg。硝态氮是水质监测的重要项目之一。有些国家已将含氮订入了湖沼水质的标准。
