摘　　要：为火龙果生产上的合理施肥提供科学依据,采用3414试验设计,研究了氮、磷、钾肥配施对火龙果产量及品质的影响。结果表明:不同氮、磷、钾肥的配施水平均可显著提高火龙果的产量,但处理15(常规施肥区)与处理9(3414试验的最高产量)的产量无显著差异;不同施肥处理对火龙果果实的可溶性固形物、总糖、总酸及矿质营养元素的影响程度各不相同,果实中的N、P、K元素含量并不随氮、磷、钾肥用量的增加而提高,可能与火龙果的生长特性和植株对养分的分配需求密切相关。The ＂3414＂ test was used to study the effects of N, P and K combination on yield and quality of pitaya to provide the scientific basis for rational application in pitaya production. The results showed that the tested different N, P and K combinations all improved yield of pitaya significantly, but there was no significant difference in yield between Treatment 15 （the convention application plot and Treatment 9 （the highest yield in the ＂3414＂ test）. Different N, P and K combination had different effects on soluble solids, total sugar, total acid and mineral elements of pitaya fruit, but the N, P and K content in pitaya fruit didn＇t increased with increment of N, P and K application, which may be closely related to growth characteristics and nutrient distribution and demand of pitaya.
