摘要
[目的]研究晚熟玉米品种郑单958在宁夏引黄灌区的最佳种植密度。[方法]在宁夏引黄灌区,以晚熟玉米品种郑单958为试验材料,采用随机区组排列,研究不同密度条件下,玉米品种的主要农艺性状、产量水平。[结果]各处理产量在8 059.35-17 292.00kg/hm^2。其中处理⑩最高,为17 292.00 kg/hm^2,处理①最低,为8 059.35 kg/hm^2。处理⑩显著高于处理①、②、③、④、⑤、⑧等6个处理,处理④、③、②和①之间存在极显著差异,处理⑩与处理⑥、⑦、⑨、（11）（12）等处理之间产量无显著差异。[结论]为了节本增效建议生产上采用处理6（9.0万株/hm^2）进行种植。
[Objective]In order to study late maturing varieties zhengdan 958 optimum density in the Yellon River irrigation area of Ningxia.[Method]In the irrigation area of Ningxia,taking Zheng dan958 as test material,using randomized block arrangement main agronomic traits and yield level under different densities were studied. [Result]The results showed that the yield of the treatments was between 8 059. 35-17 292. 00 kg / hm^2. The highest of treatment ⑩ was 17 292. 00 kg / hm^2,and the lowest of treatment 1 was 8 059. 35 kg/hm^2. treatment 10 was significantly higher than that of treatment ①,②,③,④,⑤,⑧. Treatment④,③,② and ① existed significant differences,the yield of treatment ⑩ and ⑥,⑦,⑨,（11）,（12） have no significant difference. [Conclusion] In order to reduce cost and increasing the benefit,the treatment ⑥ was proposed for planting in the production.
