补充资料:控释肥料(control release fertilizers)
分子式:
CAS号:
性质:又称缓效肥料(slow available fertilizers)或控释肥料(control release fertilizers)。肥料中含有养分的化合物在土壤中释放速度缓慢或者养分释放速度可以得到一定程度的控制以供作物持续吸收利用。使用缓释肥料的目的:(1)减少肥料养分,特别是氮素在土壤中的损失;(2)减少施肥作业次数,节省劳力和费用;(3)避免发生由于过量施肥而引起的对种子或幼苗的伤害。缓效肥料分三大类:(1)难溶于水的化合物,如磷酸镁铵等;(2)包膜或涂层肥料,如包硫尿素等;(3)载体缓释肥料,即肥料养分与天然或合成物质呈物理或化学键合的肥料。
