摘　　要：以两年生金丝小枣砧木冬枣嫁接苗为实验对象,通过盆栽模拟实验,研究分析不同氮、磷、钾施肥配比条件下的座果率、产量及果品质量三方面的差异,确定最优施肥配比,以期指导冬枣科学合理施肥。研究结果表明,盆栽模拟实验中以氮、磷、钾按2∶1∶2配比施肥时效果最佳,可显著提高坐果率和产量;相同施肥配比条件下,适量施用有机肥,有利于提高果实品质,提高果实可溶性固形物、总糖和维生素C的含量。In order to confirm optimal ratio of fertilization and guide scientific fertilization for winter jujube, through potted simulation experiment of two year grafted winter jujube by gold thread jujube, this article made research and analysis on the differences of fruit-set rate, yield and fruit quality, under the different fertilization proportion of nitrogen, phosphorus and potassium. The results of potted simulation experiment showed that,The best results appeard under the fertilization proportion of nitrogen, phosphorus and potassium is 2：1：2, improving fruit set percentage and yield significantly; applying appropriate amount of organic fertilizer could promote the improvement of fruit quality under the condition of the same fertilization proportion, and increase the content of soluble solids, total sugar and vitamin C.
