| 摘 要： | "氮—磷—复合肥"是一种近10年来在实际生产中出现的较为普遍的施肥模式。这种施肥模式较"氮—磷"施肥模式有进步,但仍会造成氮磷过量而钾不足,加上目前复合肥的质量难以保证,更易造成氮过量而钾严重不足。为合理施肥,有必要改变我国在农业生产上尽量避免施用氯化钾作为钾肥的不恰当做法,确保钾肥的供应,加大对化肥尤其是钾肥质量的监管力度。

| Abstract: | The fertilization model of nitrogen-phosphor-compound fertilizer are used usually in recent 10 years in China.Althongh it made more progreas than nitrogen-phosphor fertilizetion model,it caused the exassiveness of nitrogen and phosphor and deficiency of potassium especially the quality of compound fertilizer used now in countryside was difficult to assure.To fertilize properly,the habit to try to avoid applying chloride potassium in agricultural production in China should be changed,both the supply and quality of potassium fertilizer should be assured. |

| Keywords: | fertilization model nitrogen-phosphor-potassium compound fertilizer chloride potassium |
