摘　　要：为寻求玉米新品种百玉2号的最佳密度,研究了不同密度对该品种产量及主要性状的影响。试验设置了5个密度处理,在中等肥力条件下对不同密度的百玉2号群体指标进行了探讨。结果表明,不同密度对百玉2号穗长、行粒数、千粒重等影响显著,在90 000株/hm2时产量最高。The effects of different planting densities on the main agronomic traits of Maize Baiyu No.2,a new maize variety,were studied 5 planting densities treatments were set,the population indices of Baiyu No.2 with different planting densities in medium fertility condition were investigated.The results showed that different density had great influence on the spike length,grains per row and 1 000-grain weight.The yield of Baiyu No.2 was highest when the density was 90 000 plants / hm2.
