摘　　要：为优化光泽县水稻测土配方施肥方案,提高水稻肥料利用率,促进化肥减量增效,以水稻品种“中浙优8号”为试验材料,研究水稻对氮、磷、钾肥的吸收利用效果。结果表明:中浙优8号配方施肥氮肥利用率为38.37%,磷肥利用率为16.15%,钾肥利用率为45.67%,钾肥、氮肥利用率相对较高,磷肥利用率相对较小;各处理中配方施肥区产量最高,无氮区、无肥区减产较大。Experiment of nitrogen,phosphorus potassium uptake and use efficiency for Zhongzheyou 8 were conducted to optimize rice formula fertilization scheme base on soil testing,improve fertilizer use efficiency,and promote fertilizer reduction and efficiency increase in Guangze.Results showed that the nitrogen,phosphorus and potassium fertilizer use efficiency were 38.37%,16.15%and 45.67%respectively,indicated nitrogen and potassium efficiency were relatively high,while phosphorus was relatively low.The soil testing formula fertilization treatment obtained highest yield,no nitrogen and no fertilization treatment had a large amount yield loss.
