钾是作物生长发育所必须的三大主要营养元素之一,土壤中常因钾供应不及时和数量不足而影响作物的产量。随着农业生产的发展,农民科学种田水平的不断提高,高产作物面积的扩大,氮、磷化肥施用量的大量增加,对钾肥的需要量也逐年增多。为了使钾肥在农业生产中发挥更大的增产作用,必须要掌握科学的施用方法,做到因作物、因土质和根据钾肥的特性合理施用。 Potassium is one of the three major nutrients necessary for crop growth and development. Soil often affects crop yields due to the short supply of potassium and insufficient quantities of potassium. With the development of agricultural production, farmers continue to raise the level of scientific farming, the expansion of high-yielding crops, nitrogen and phosphorus fertilizer increased significantly, the demand for potash also increased year by year. In order for potash fertilizer to exert greater stimulation effect in agricultural production, it is necessary to master the scientific application method so that it can be reasonably applied due to crop, soil type and characteristics of potash.
