摘　　要：研究了2个高淀粉玉米新品种5个种植密度与产量及质量的关系。结果表明:密度对产量的影响达极显著水平,吉单79和吉单137获得最高产量的适宜种植密度分别为5.51万株/hm2和5.43万株/hm2。分析了种植密度对子粒品质的影响。生产上可采用适宜的密度以获得高产、稳产、优质。2 high starch maize new variety has studied under the medium fertility condition, planting density and output and quality relations. The result indicated that the densities influence reaches extremely remarkable level to the yield. Jidan 79 and Jidan 137 obtains the maximum production rate the suitable planter density respectively is 55 100 plant/ha and 54 300 plant/ha. Preliminary discussion planting density to grain quality influence. In order to high and stable production,the best density, can achieves the highest per unit area yield and higher quality.
