从黄县城关公社近十年的生产实践看,施氮肥比较多,施磷、钾肥比较少,因而部分地块土壤中氮、磷、钾比例失调,这是在目前施肥问题上影响小麦产量继续提高的重要原因之一,本文主要从我社的土壤肥力及产量要求出发,探讨施磷、钾肥的重要性,研究氮、磷、钾肥配合使用的比例,为科学施肥提供依据. According to the production practice of commune of Huangxian Chengguan in recent ten years, there are more nitrogenous fertilizers and relatively less phosphorus and potassium fertilizer, so the proportions of nitrogen, phosphorus and potassium in some plots of soil are imbalanced, which is affecting the yield of wheat on the current fertilization issue One of the important reasons for this increase is to discuss the importance of applying phosphorus and potassium fertilizers and to study the proportion of nitrogen, phosphorus and potassium fertilizers to provide the basis for scientific fertilization.
