摘　　要：本文以耐密型玉米品种郑单958为试验材料,采用单因素随机区组设计,在田间种植条件下,研究了耐密型玉米产量及其性状与种植密度的关系。研究结果表明,在天津地区以郑单958为代表的耐密型玉米夏播的最佳密度为4850株/667m2。并通过不同种植密度对玉米产量要素影响的研究,基本掌握了种植密度与产量要素的变化关系及对玉米产量的贡献变化。In this paper, the high density tolerant maize ＇Zhengdan 958＂ as the test material, an experi- mental design with a single factor and randomized blocks was used to study the relationship between planting density and yield traits of high density tolerant maize under the field planting conditions. The results indicat- ed that the best summer planting density for high density tolerance maize varieties represented by＇Zhengdan 95g＇was 4850 plants/667m^2 in Tianjin. Through the research of planting density on the effects of corn yield factors, we basically made clear the relationship between the planting density and production elements, and with the increase of planting density, how the contribution of yield elements on corn production changes.
