| 摘 要： | 研究了氮磷钾肥对6a树龄红枣产量和品质的影响。结果表明:新疆南部红枣最高产量施肥量为N691.5 kg/hm2,P2O5 577.5 kg/hm2,K2O 72 kg/hm2,施用比例1:0.84:0.11。采用平衡施肥能增加红枣产量,降低红枣果实中总酸度,并能增加红枣果实中水解还原糖和VC含量,从而提高红枣产品品质,增加效益。红枣果实中总酸度随氮肥施用量增加而增加;磷钾肥能降低总酸度。当氮、磷、钾肥分别控制在600、180～450、75kg/hm2时能显著提高红枣果实中水解还原糖和VC含量。

| Abstract: | Through the practice of nitrogen,phosphorus,potassium fertilizer in this experiment,studied the influence on yield and quality of Zizvphus jujube that were cultivated about 6 years.The results showed that it could achieve the high yield under the condition of applying nitrogen（N） 691.5 kg/hm～2,phosphorus（P2O5） 577.5 kg/hm～2 and potassium （K2O） 72 kg/hm～2 with a ratio of 1:0.84:0.11（N P2O5 K2O）.It was clear that balanced fertilization can raise the yield of Zizvphus jujube and decrease the content of total acidity and increase the content of hydrolyze deoxidize sugar and vitamin C and then improve the quality and economic benefit of Zizvphus jujube.Total acidity content in Zizvphus jujube can be increased by nitrogen application and reduced by application of phosphorus and potassium.The content of hydrolyze deoxidize sugar and vitamin C significantly increased under the condition of applying nitrogen（N） 600 kg/hm～2, phosphorus（P2O5）180～450 kg/hm2 and potassium（K2O）75 kg/hm2. |
