对10个中熟玉米新品种进行筛选试验,分析品种对生育期、生物学性状及产量的影响,结果表明:产量排名前5位的是吉单56、吉单631、吉单53、吉单441、吉单558,产量分别为12 730.5、12 336.0、12 289.5、11 782.5、11 737.5 kg/hm~2。从综合技术指标来看,在桦甸市应该进行多点大区示范种植吉单56、吉单631、吉单53、吉单441、吉单558,种植密度不小于6.9万株/hm~2。
Ten medium maturing maize varieties were screened to test their effects on the growth period, biological characters and yield. The results showed that the top five producers were Jidan 56, Jidan 631, Jidan 53, 441 and Jidan 558 respectively, the output was 12 730.5,12 336.0,12 289.5,11882.5,11 737.5 kg / hm -2, respectively. From the comprehensive technical indicators, in Huadian City should carry out demonstration in more areas of demonstration planting Jimo 56, Jidan 631, Jidan 53, Jidan 441, Jidan 558, planting density of not less than 6.9 million plants / hm ~ 2 .
