在化肥所含成分中,只含一种营养元素的肥料,通称为单质肥料。同时含有氮、磷、钾、微量元素等两种或两种以上营养成分的化肥,叫做复合肥或混合肥料。含两种主要营养元素的叫二元复合肥料;含三种主要营养元素的叫三元复合肥料;含有三种以上营养元素的叫多元复合肥料。复合肥料有许多优点,普遍受到农民群众的欢迎,但由于施用方法不当,造成肥料浪费,降低了施肥效果。一、复混肥的区别复合肥料是经过化学方法使肥料中两种或两种以上的营养成分之间起化学作用,形成一种新的化合物。这种新的化合物就称为复合肥。混合肥料是把两种或两种以上的单质肥料,或复 Fertilizer contained in the composition, containing only one nutrient element of the fertilizer, commonly known as the elemental fertilizer. At the same time containing nitrogen, phosphorus, potassium, trace elements such as two or more nutrients of fertilizers, called compound fertilizer or compost. Contains two main nutrients called binary compound fertilizer; containing three main nutrients called ternary compound fertilizer; contains more than three kinds of nutrients called multi-compound fertilizer. Compound fertilizer has many advantages, generally welcomed by farmers, but due to improper application methods, resulting in waste of fertilizer, reducing fertilizer. First, the difference between compound fertilizer Compound fertilizer through chemical methods to fertilizer two or more nutrients play a chemical role between the formation of a new compound. This new compound is called compound fertilizer. Compost is a mixture of two or more elements of fertilizer, or complex
