补充资料:氮肥
氮肥
nitrogen fertilizer

   具有氮( N)标明量的单元肥料。施于土壤或植物可提高植物的氮营养水平。按氮的化学形态可分为三大类:①铵态氮肥 ,氮以!!!D0478_1形态存在。主要有氨水 、液氨、碳酸氢铵、硫铵、氯化铵等。②硝态氮肥,氮以!!!D0478_2形态存在。主要有智利硝石(硝酸钠)、硝酸钙;同时含有!!!D0478_3 !!!D0478_4的氮肥有硝酸铵、硫硝酸铵、硝酸铵钙等。③酰胺态氮肥,氮以酰胺基形态存在。主要有尿素等。中国常用的氮肥有尿素、氨水、碳酸氢铵、硝酸铵、硫铵、氯化铵和含氮复合肥料。
   氮肥施入土壤后,其中的氮素被当季植物吸收,一部分通过微生物的同化和粘粒矿物的固定等作用而残留在土壤中;还有一部分则通过各种途径,如氨的挥发、反硝化作用、淋洗作用和径流等离开土壤 -植物系统而损失掉 。土壤氮素含量、形态及其转化和供氮能力与氮肥肥效关系极大。土壤中氮分为无机态和有机态 2类 。无机态氮中,粘土矿物固定态的铵约占土壤全氮量的 2%  3%,能被植物直接吸收利用,称有效态氮。有机态氮约占土壤表土全氮量的 90%或更高,经微生物分解转化为铵态氮和硝态氮后,易为作物吸收。
