南通市海门区玉米氮磷钾肥料利用率研究

The Study on the Utilization Rate of Nitrogen,Phosphorus and Potassium Fertilize for Maize in Haimen District of Nantong City

通过田间常规和配方施肥下氮肥、磷肥和钾肥的缺素对比试验,探讨南通市海门区玉米应用测土配方施肥技术后氮肥、磷肥和钾肥的实际肥料利用率。结果发现,氮肥对玉米产量影响较大,肥料利用率适中,钾肥肥料利用率较高,磷肥肥料利用率较低。

Based on the comparative tests of the deficiency of nitrogen,phosphorus and potassium fertilizers between conventional fertilization and soil testing fertilization formula in the fields.Discussing the actual utilization rate of nitrogen,phosphate and potassium fertilizers for maize after applied soil testing fertilization technology in Haimen District of Nantong City.The results show that the nitrogen fertilizer has a greater impact on maize yield,the utilization rate of fertilizer is moderate.The utilization rate of potassium fertilizer is higher and the utilization rate of phosphorus fertilizer is lower.
