参考词条
补充资料:氮肥施用“九不宜”
    一是铵态氮肥不宜与碱性肥料混用。因为混施后会产生氨气,降低肥料效果。常用的铵态氮肥有碳铵、硫酸铵等,碱性肥料有草木灰、石灰等。
    二是硝态氮肥不宜与有机肥混用。有机肥含有较多有机物,遇到硝态氮肥会在反硝化细菌的作用下发生硝化反应,损失氮素。常用的硝态氮肥有硝酸铵、硝酸钠、硝酸铵钙等。
    三是硝态氮肥不宜在田中施用。硝态氮肥在厌氧条件下,易被反硝化细菌分解造成氮素损失,降低肥效。旱地应禁止在大雨前后施用或施用后浇大水。
    四是尿素不宜浇施。因为施入土壤后,尿素经过土壤微生物的作用,会水解成碳酸氢铵,然后分解出氨而挥发。
    五是尿素不宜紧贴种子。尿素含有少量缩二脲,会影响种子发芽,浓度过高时会使种子中毒。用尿素作种肥时,不要直接接触种子或控制尿素施用量。
    六是尿素作根外追肥浓度不宜过高。用作叶面肥,尿素效果确实好,但不能盲目加大用量。
    七是碳酸氢铵不宜施在土表太久。忌浅施,碳酸氢铵的性质不稳定,施后应立即覆盖。
    八是硫酸铵不宜长期施用。硫酸铵属于酸性肥料,长期施用会增加土壤酸性,破坏土壤结构。施用在碱性土壤上,硫酸根离子会与钙离子作用使土壤板结。因此,要与其他氮肥交替使用。
    九是不宜施在忌氮作物上。如施用在忌氮作物上会使作物生理机能遭到破坏,严重时会使作物死亡。(来源:《中国花卉报》2004.01.06)
