|nitrogen fertilizer;[肥料]氮肥
氮肥（Nitrogenous Fertilizer） 是指一类以提供植物所需氮素（N）为主要养分的肥料。氮是植物生长发育不可或缺的大量元素之一，是构成蛋白质、叶绿素、核酸（如DNA和RNA）、维生素和许多酶的关键成分。施用氮肥的主要目的是补充土壤中氮素的不足，以满足作物对氮素的需求，从而促进植物茎叶生长、增强光合作用、提高作物产量和品质。
根据氮素存在的化学形态和化合物性质，主要氮肥类型包括：
参考资料：
"氮肥（nitrogenous fertilizer）"是含有氮元素的一类化学肥料，主要用于促进植物生长。以下是详细解释：
核心作用 氮元素是植物体内蛋白质、叶绿素、核酸等关键物质的主要成分，直接影响叶片发育、光合作用效率和作物产量。缺乏氮素会导致叶片发黄、生长迟缓。
主要类型
典型施用公式（以尿素为例）： $$ text{施用量} = frac{text{目标产量需氮量} - text{土壤供氮量}}{text{尿素含氮量} times text{利用率}} $$
