随着农业的不断持续发展,为了进一步降低生产成本,提高经济效益,化肥投入量逐渐需要合理化,人们使用化肥的品种也由单一化需要向多元化方向发展。在我县农业生产中常用的化肥类型主要有氮肥类、磷肥类、钾肥类、复合肥等。
With the continuous and continuous development of agriculture, in order to further reduce production costs and increase economic efficiency, the input of chemical fertilizers gradually needs to be rationalized. The variety of fertilizers used by people also needs to be diversified from a single need. In my county agricultural production commonly used types of fertilizers are mainly nitrogen, phosphorus, potassium, compound fertilizer and so on.
