测土配方施肥以土壤化验和肥料田间试验为基础,根据作物的需肥规律、土壤的供肥性能和肥料效应,在合理施用有机肥料的同时提出氮、磷、钾及中、微量元素等肥料的施用量、施用时间及施用方法。实践证明推广测土配方施肥技术,可以提高化肥利用率3-5%,增产率一般为10-15%,高的可达20%以上。实行测土配方施肥不但能提高肥料利用率,获得稳产、高产,还能改善农产品质量,是一项增产节肥、节支增收的技
Soil testing and formula fertilizers based on soil tests and fertilizer field tests, according to the law of fertilizer demand, soil fertility and fertilizer effects, in the rational use of organic fertilizers at the same time proposed nitrogen, phosphorus, potassium and trace elements such as fertilizers The amount of administration, the time of administration and the method of administration. Practice has proved that the promotion of soil testing and fertilizer technology, fertilizer can increase the efficiency of 3-5%, the rate of increase is generally 10-15%, high up to 20% or more. The implementation of soil testing and formula fertilization can not only improve fertilizer utilization, access to stable yield, high yield, but also improve the quality of agricultural products, is an increase of fertilizer, saving income technology
