化肥可以根据不同的分类方式进行归类,以下是几种常见的分类方法及相应的化肥种类:

1. 按照营养元素含量分类:
– 氮肥:如尿素、铵态氮肥、硝态氮肥等,主要提供植物所需的氮元素。
– 磷肥:如磷酸二铵、磷酸一铵、磷酸三铵等,主要提供植物所需的磷元素。
– 钾肥:如氯化钾、硫酸钾等,主要提供植物所需的钾元素。
– 复合肥:含有多种营养元素,如氮磷钾复合肥、氮磷复合肥等。

2. 按照制造工艺分类:
– 化学合成肥料:通过化学反应合成的肥料,如尿素、硝酸铵等。
– 生物有机肥料:以动植物的废弃物、有机物等为原料制成的肥料,如腐熟堆肥、鸡粪肥等。
– 矿物质肥料:以矿石、矿渣等为原料制成的肥料,如磷矿肥、钾肥等。

3. 按照使用对象分类:
– 应用于农田的肥料:主要用于农作物的生长,如氮磷钾复合肥、尿素等。
– 应用于园艺的肥料:主要用于花卉、果树等园艺植物的生长,如磷酸二铵、硫酸钾等。
– 应用于草坪的肥料:主要用于草坪的养护和修剪,如速效复合肥、有机肥料等。

通过以上分类方法,可以更好地了解和选择适合不同植物和土壤需求的化肥种类。

  1. 按照营养元素分为:氮肥磷肥钾肥、复合肥和微量元素肥等。
  • 氮肥: 如尿素、铵态氮肥、硝态氮肥等;
  • 磷肥: 如过磷酸钙、复合磷肥、磷铵等;
  • 钾肥: 如氯化钾、硫酸钾等;
  • 复合肥: 如NPK复合肥等;
  • 微量元素肥: 如硼肥、锰肥、铜肥等。
  1. 按照物理状态分为:固体肥料、液体肥料和气态肥料等。
  • 固体肥料: 如硫酸铵硝酸铵、过磷酸钙等;
  • 液体肥料: 如尿素水溶液、硝酸钾水溶液等;
  • 气态肥料: 如氨气氮气等。
  1. 按照使用方式分为:基肥、追肥和叶面肥等。
  • 基肥:是指在种植前或种植初期施用的肥料,如有机肥料、磷酸二铵等;
  • 追肥:是指在植株生长过程中根据需要进行施用的肥料,如尿素、硝酸铵等;
  • 叶面肥:是指喷施在植物叶面的肥料,主要包括微量元素肥料和叶面生长调节剂等。

这些分类方式并不是完全独立的,有时化肥也可以同时属于不同的分类。


There are various ways to categorize fertilizers based on different criteria. Some commonly used classification methods include:

  1. Based on Nutrient Content: Fertilizers can be classified based on the primary nutrient they provide, such as Nitrogen (N), phosphorus (P), and potassium (K), as well as other secondary and micronutrients. This includes:
  • Nitrogen fertilizers: such as urea, ammonium nitrate, and ammonium sulfate.
  • Phosphorus fertilizers: such as superphosphate, triple superphosphate, and diammonium phosphate.
  • Potassium fertilizers: such as potassium chloride, potassium sulfate, and potassium nitrate.
  • Compound fertilizers: such as NPK fertilizers that contain varying amounts of nitrogen, phosphorus, and potassium.
  • Micronutrient fertilizers: such as zinc, copper, and boron fertilizers.
  1. Based on Physical State: Fertilizers can also be classified based on their physical state. This includes:
  • Solid fertilizers: such as granular, prilled, or powdered forms.
  • Liquid fertilizers: such as liquid solutions or suspensions.
  • Gaseous fertilizers: such as anhydrous ammonia or nitrogen gas.
  1. Based on Application Method: Fertilizers can also be classified based on their intended application method. This includes:
  • Base fertilizers: applied to the soil before planting or during soil preparation to provide the initial nutrient supply for the crop.
  • Top-dress or foliar fertilizers: applied during the growing season to supplement the nutrient needs of the crop.

In general, the classification of fertilizers is determined by their intended purpose, nutrient composition, physical state, and method of application.
