复合肥是在一种化肥中,含有氮、磷、钾三要素中两种和两种以上的肥料。含有任何两种要素的复合肥料称二元复合肥;同时含有三要素的肥料称为三元复合肥,合理施用复合肥要注意以下三个问题:一、了解复合肥的优缺点及分类优点:1.养分含量高,主要营养元素多。复合肥的状分总量一般比较高,营养元素种类较多,一次施用复合肥,至少同时可供应作物两种以上的主要营养元素。2.副成分少,结构均匀。复合肥养分分布比较均一,在造成颗粒后结构紧密,养分释放均匀,肥效稳
Compound fertilizer is a kind of fertilizer, containing nitrogen, phosphorus and potassium three elements of two and two or more kinds of fertilizer. Compounded fertilizers containing any two elements are called binary compound fertilizers; at the same time, fertilizers containing three elements are termed compound fertilizers. The following three questions should be paid attention to in the rational application of compound fertilizers: I. Understanding the advantages, disadvantages and classification advantages of compound fertilizers: 1. High nutrient content, the main nutrients and more. The total amount of compound fertilizer is generally higher, more types of nutrients, a compound fertilizer, at least at the same time can supply more than two crops of the main nutrients. 2 minor components, uniform structure. Nutrient distribution of fertilizer is more uniform, after the formation of particles in close structure, nutrient release uniform, stable fertilizer
