2014年，调查了宁夏灵武长枣产量、等级果率及其相关影响因素。结果表明：5年生高接换头的灵武长枣4号产量最高，达24604.5 kg/hm2；灵武长枣3号产量为19404.0 kg/hm2；定植株数为825～1245株/hm2盛果期的灵武长枣，产量为14311.5～17575.7 kg/hm2。疏散分层形整形修剪的灵武长枣，特级果率达42.85%，果实在树冠中的垂直分布呈“金字塔”形；纺锤形改造修剪的特级果率为0.0%，果实在树冠中的垂直分布呈“倒金字塔”形；二者共同特征是，树冠中下部主枝无效结果带达50～100 cm。讨论了优化灵武长枣（小冠）自由纺锤形树体结构及参数。

In 2014, the yield, graded fruit rate and relevant affecting factors of Ningxia Lingwu long jujube were investigated. The results showed that the yield of 5 years old high scion Lingwu Long Jujube No.4 was the highest, reaching 24 604.5 kg/hm2, the yield of Lingwu Long Jujube No.3 was 19 404.0 kg/hm2 and the yield of the fruiting period Lingwu long jujube with the density of 825~1 245 plants/hm2 was 14 311.5~17 575.7 kg/hm2. The super fruit rate of the Lingwu long jujube pruned as a sparsely-layered shape was 42.85% and the vertical distribution of the fruit in the crown showed a "pyramid"shape. The super fruit rate of the Lingwu long jujube restructured and pruned as a fusiform was zero and the vertical dis-tribution of the fruit in the crown showed a "reverse pyramid" shape. The common characteristics of the above-mentioned were that the invalid fruiting zone of the lower crown branches reached 50~100 cm. A discussion is made on optimizing the structure and parameters of the free spindle shape tree of Lingwu long jujube (small crown).
