| 摘 要： | 目的 研究土壤、叶片、果实养分与灵武长枣Zizyphus jujuba ‘Lingwuchangzao’品质的关系，用于建立灵武长枣的科学施肥体系。 方法 以宁夏灵武市5个灵武长枣栽植基地的果实、果树叶片及土壤为试材，通过多重线性逐步回归分析，研究了灵武长枣果实品质与土壤肥力、叶片养分的相关性。 结果 不同栽植基地土壤肥力差异较大，栽植基地普遍缺锰；灵武长枣果实纵径与土壤全钾、果实硬度与果实氮呈负相关；果实滴定酸与土壤速效钾、叶片磷、果实氮呈正相关，与果实铁呈负相关；果实氮与土壤有机质、叶片铁、果实锌呈正相关，与土壤硒呈负相关；果实钾与土壤有效铁呈负相关，与土壤全磷呈正相关；果实锌与土壤速效钾、叶片锌、果实氮呈正相关。 结论 灵武长枣栽植基地应增加有机肥和微量元素的施用量，特别是锰，而应减少铁的施用量。表11参24

| Abstract: | Objective To establish a scientific fertilization system for Zizyphus jujuba ‘Lingwuchangzao’, the current study is aimed to figure out the correlation of soil, leaves and fruit nutrients with the quality of the above mentioned jujube. Method With the soil, leaves and fruit nutrients of 5 Z. jujuba ‘Lingwuchangzao’ as the study subjects, by using the multiple linear stepwise regression analysis the relationship between fruit quality with the soil fertility and leaf nutrients was established. Result The soil fertility properties of different planting bases were significantly different, and Mn was generally lacking in planting bases. The longitudinal diameter of fruit was negatively correlated with the soil total K, the fruit hardness and the fruit N content. The fruit titration acid content was positively correlated with the content of soil available K, leaf P and fruit N, but negatively correlated with the content of fruit Fe. The content of fruit N was positively correlated with the content of soil organic matter, leaf Fe and fruit Zn, but negatively correlated with the content of soil Se. The K content of fruit was negatively correlated with the effective Fe content of soil, but positively correlated with the total P content of soil. The content of Zn in fruits was positively correlated with the content of available K in soil, Zn in leaves and N in fruits. Conclusion The application amount of organic fertilizer and trace element fertilizer should be increased in the planting bases of Z. jujuba ‘Lingwuchangzao’, especially that of Mn, while that of Fe should be reduced.
