对复合肥料的合理施用,必须注意:1)因土因作物确定复合肥料适宜的施用量、施用期和施肥部位;2)需考虑其所含营养元素的种类、含量和形态;3)考虑N、P2O5、K2O的相对比例。只有这样,才能充分发挥复合肥料中每种营养元素的效益,避免或减少不必要的损失和浪费。
The rational application of compound fertilizers, we must pay attention to: 1) due to soil fertilizers to determine the appropriate compound fertilizer application rate, application period and fertilization sites; 2) need to consider the type, content and morphology of the nutrients contained; 3) , P2O5, K2O relative ratio. Only in this way can we give full play to the benefits of each nutrient in compound fertilizers and avoid or reduce unnecessary losses and waste.
