草木灰不能与铵肥(如碳酸氢铵、硫酸铵、氯化铵等)混用,主要原因是草木灰呈碱性,而铵肥含有铵离子(NH4+),两者混合会发生化学反应,导致氨气(NH3)挥发,从而降低铵肥的肥效。
具体原因:
1. 草木灰的碱性
草木灰的主要成分是碳酸钾(K2CO3)、碳酸钙(CaCO3)等,呈碱性,能与铵肥中的铵离子(NH4+)发生化学反应。
2. 化学反应释放氨气
当草木灰与铵肥混合时,碱性物质会与铵离子发生反应,生成气态氨(NH3),导致氮素流失:
NH4+ + OH− → NH3↑ + H2O
这会使氨气挥发,降低氮肥的利用率,甚至对作物和环境产生不良影响。

结果:
正确使用方式:
因此,在施肥时需要注意不同肥料的性质,合理搭配,以保证养分的最大化吸收和利用。
