摘　　要：在贵州都柳江河谷,以纽荷尔脐橙11年生树为材料,研究了不同施肥水平对纽荷尔脐橙产量、品质、树体营养水平和经济效益的影响。结果表明,在贵州都柳江低热河谷土壤条件下,用N∶P∶K质量比为8∶6∶6、有效含量为25%的有机复合肥,每年1.5kg.株-1的施肥水平,不能满足脐橙对养分的需求,产量和品质及经济效益较低;每年3kg.株-1的施肥水平,树体叶片的多数营养元素含量值低于叶分析营养诊断适宜值,增产的潜力没有得到应有的发挥;每年5kg.株-1的施肥水平,树体叶片的元素含量值达到叶分析营养诊断适宜值范围,脐橙的产量较高,品质和经济效益较好。The yield, quality and economic return of navel orange are investigated when different levels of fertilizers are applied to the 11-years-old Newhall navel orange trees in Duliu River valley of Guizhou province. The results show that applying 25% multiple fertilizer of N： P： K（8： 6： 6） with 1.5 kg per tree were insufficient to meet the plant＇ s nutrient needs, therefore the yield and quality of orange was poor. in fact, even the yearly fertilizer level increased to 3 kg per tree, the contents of most nutrient dements in leaves lowered than that of ＇ fitting values＇ of nutrient diagnosis and the yield was not satisfying. Only when the yearly fertilizer level was up to 5 kg per tree, the contents of nutrient dements in leaves reach to the range of fitting values and inevitably the orange was high-yield, good-quality and better economic return.
