摘　　要：2008-2011年,在兴山县柑橘主产区设置8个"325"试验,以探索氮、磷、钾肥施肥效果。结果表明,氮肥的增产效果最好,平均增产9 316 kg/hm2,钾肥次之,平均增产6 417 kg/hm2,磷肥最低,氮、磷、钾肥农学效率分别为29.0、38.9、23.6 kg/kg。氮磷钾肥配施能一定程度上提高柑橘糖分。In order to study the fertilization effects of nitrogen（N）,phosphor （P）,potassium （K） on citrus,8 experiments were conducted at Xingshan county from 2008 to 2011.The results showed that N had the best increase of yield with 9 316 kg/hm^2,followed by K with 9 316 kg/hm^2.The agronomic efficiency of N,P,K were 29.0,38.9 and 23.6 kg/kg,respectively.The balanced fertilization of N,P,K increased the content of sugar in citrus.
