摘　　要：在广元市朝天区矿质黄壤立地条件下,对核桃开展氮、磷、钾肥的配合施用试验,探讨核桃的施肥配比,为生产上核桃合理施肥提供依据。应用L9(34)正交设计,进行氮、磷、钾肥料施肥配比试验。结果表明:3种肥料对核桃产量的效果排序是磷肥>钾肥>氮肥;氮、磷、钾3种肥料配比施肥的不同处理对核桃产量有很大的影响,在矿质黄壤上,核桃年施肥量的最佳配比为尿素1 200 g·株-1+过磷酸钙1 500 g·株-1+硫酸钾940 g·株-1。In order to obtain the suitable fertilization formula of Juglans regia L.,the experiment of fertilizer of nitrogen,phosphorus and potassium was conducted by orthogonal design on the gravel yellow earth soil in Chaotian District of Guangyuan City. The results showed that the effect of three kind of fertilizers on the yield of J. regia was descendingly phosphorus〉 potassium 〉nitrogen,and different disposals of fertilizer of nitrogen,phosphorus and potassium had obvious effects on the yield of J. regia. It was recommended that annual fertilization rate was 1 200 g urea,1 500 g calcium superphosphate and 940 g potassium sulphate for each tree on the gravel yellow earth soil.
