小麦产量的提高主要依赖于品种的更新和栽培技术的改良,而肥料的用量和施肥方法则是栽培的主要研究对象。配方施肥是当前科学施肥的发展方向,它是根据土壤养分含量状况和供肥能力,以及产量指标来确定施用的氮、磷、钾及微量元素的合理配比,在满足小麦各生育时期对肥料 The increase of wheat yield mainly depends on the improvement of varieties and cultivation techniques, and the amount of fertilizers and fertilization methods are the main research objects of cultivation. Formula fertilization is the current development direction of scientific fertilization, which is based on the status of soil nutrients and fertilizer supply capacity, as well as output indicators to determine the application of nitrogen, phosphorus, potassium and trace elements in a reasonable ratio to meet the fertility of wheat during each fertilization period
