摘  要:[目的]研究肥东县配方施肥提高氮肥、磷肥和钾肥利用率的效果。[方法]通过水稻田间氮肥、磷肥和钾肥的对比试验,了解不同施肥量对水稻生长的作用和效果。[结果]不施氮肥,水稻植株矮小,生育期缩短,产量低,千粒重最高;施用配方肥水稻有效穗数提高,经济产量最高;此次试验氮肥利用率为42.08%,磷肥利用率为17.23%,钾肥利用率为51.23%。[结论]配方肥的施用可有效提高肥料利用率。[Objective]The aim of this study was to study the effect of formula fertilization on the utilization of nitrogen,phosphorus and potassium in Feidong County.[Method]Through the comparative experiment of nitrogen,phosphorus and potassium fertilizer in rice field,the effect of different fertilization amount on rice growth was understood.[Result]Without nitrogen fertilizer,the rice plant was short,the growth period was shortened,the yield was low and the weight of 1000 grain was the highest.The effective panicle number of rice with formula fertilizer was increased,and the economic yield was the highest.The utilization rate of nitrogen fertilizer,phosphorus fertilizer and potassium fertilizer in this experiment was 42.08%,17.23%and 51.23%,respectively.[Conclusion]The application of formula fertilizer could effectively improve the utilization rate of fertilizer.
