测土配方施肥是以土壤测试和肥料田间试验为基础,根据作物需肥规律、土壤供肥性能和肥料效应,在合理施用有机肥料的基础上,提出氮、磷、钾及中、微量元素等肥料的施用数量、施肥时期和施用方法。通俗地讲,就是在农业科技人员指导下科学施用配方肥。测土配方施肥技术的核心是调节和解决作物需肥与土壤供肥之间的矛盾。同时有针对性地补充作物所需的营养元素,作物缺什么元素就补充什么元素,需要多少补多少,实现各种养分平衡供应,满足作物的需要;达到提高肥料利用率和减少用量,提高作物产量,改善农产品品质,节省劳力,节支增收的目的。
Soil testing and formula fertilization is based on soil testing and fertilizer field tests. Based on the principle of crop fertility, soil fertility and fertilizer effect, nitrogen, phosphorus, potassium and trace elements are proposed based on the rational application of organic fertilizers The amount of fertilizer applied, the period of fertilization and the method of application. Practically speaking, it is the scientific application of formula fertilizer under the guidance of agricultural science and technology personnel. Soil testing and fertilization technology is the core of regulation and solution to the conflict between crop fertilizer and soil for fertilizer. At the same time targeted to supplement the nutrients needed for crops, the crops lack what elements to supplement what elements need to make up for how much to achieve a variety of nutrient balance supply to meet the needs of crops; to improve fertilizer utilization and reduce the amount of increased crops Yield, improve the quality of agricultural products, labor-saving, income-saving purposes.
