延伸阅读

铵态氮分子式:CAS号:性质:以铵离子(NH4+)形态存在于土壤、植物和肥料中的氮素,常用符号NH4+—N表示。硫酸铵、氯化铵、碳酸氢铵、液氧、氨水都是铵态氮肥。土壤中的铵态氮可被土壤胶体吸附,呈交换性铵状态氮肥。土壤中的铵氮可被土壤胶体吸附,呈交换性铵状态存在,也可溶解在土壤溶液中,能直接被植物吸收利用,属于速效性氮素。通常土壤中铵态氮的含量为1.4~30mg/kg,在东北黑土中可达50 mg/kg以上。土壤铵态可通过硝化作用而转化为硝态氮,每吸收一个铵离子(NH4+),即产生一个氢离子(H+),形成的氨进入植物体内后与呼吸基质时产生的酮酸化合,生成多种氨基酸和酰胺,并进一步合成蛋白质。因此,正常生育的植物体内不存在游离的铵态氮。铵态氮肥是速效性肥料,可作基肥和追肥用。但由于铵盐中阴离子不同,应根据土壤作物、气候等条件选择适宜的铵态氮肥。如氯化铵,因含有氯离子,不宜用于盐渍土或忌氯作物。
