我国使用肥料首先是氮肥,其次是磷肥,接着是钾肥和微量元素肥料等,肥料的使用经历了不断的提高的进程,60年代,我国针对如何减少肥分损失、提高肥料利用率和增进肥效展开研究工作,取得了很好的成果。80年代,随着肥料施用量迅速增加,施用单一肥料和依靠经验的施肥方法已越来越不适合农业生产发展的需求,肥料的适宜用量及氮磷钾合理比的研究应运而生。定兴县在2004年进行菜地地力调查;2009-2012年开展测土配方施肥工作;2009-2012年进行耕地地力调查,
China’s use of fertilizers is the first nitrogen fertilizer, followed by phosphate fertilizer, followed by potassium and trace element fertilizers, the use of fertilizers have undergone continuous improvement process, the 60’s, our country on how to reduce fertilizer loss, improve fertilizer utilization and enhance fertilizer efficiency Research work has yielded very good results. In the 1980s, with the rapid increase of fertilizer application rate, the application of single fertilizer and experienced fertilization methods have become increasingly unsuitable for the development of agricultural production. The appropriate amount of fertilizer and the reasonable ratio of NPK have emerged. Dingxing County in 2004 to carry out ground-fertility survey; 2009-2012 to carry out soil testing and fertilizer work; 2009-2012 arable land productivity survey,
