摘要
玉米品种嫩单29为2020年黑龙江省审定品种,黑龙江省农业科学院齐齐哈尔分院玉米育种研究室于2018-2019年分别在齐齐哈尔、大庆、兰西、安达、青冈、龙江、泰来进行品种对比试验(CK为先玉696)。结果表明:嫩单29具有较强的抗病性和抗逆性;增产幅度明显,稳定性强;适合于黑龙江省第一积温带下限、第二积温带上限种植,生育天数125d,有效积温2600℃。机械化收获应种植在有效积温2750℃的区域。不同地区表现出不同程度缺陷,可以利用化控技术、合理施肥、病害防控等技术弥补不足,促进粮食增产、增收,保障粮食生产安全。
Maize variety Nendan 29 was approved by Heilongjiang Province in 2020.Maize Breeding Research Office of Qiqihar Branch of Heilongjiang Academy of Agricultural Sciences conducted variety comparison tests in Qiqihar,Daqing,Lanxi,Anda,Qinggang,Longjiang and Tailai from 2018 to 2019(CK was Xianyu 696).The results showed that,Nendan 29 had strong disease resistance and stress resistance;its yield increased significantly with strong stability;it was suitable for planting on the first accumulated temperature zone and the second accumulated temperature zone in Heilongjiang Province,with a growth period of 125 days and an effective accumulated temperature of 2600℃.Mechanized harvesting should be planted in the effective accumulated temperature of 2750℃.Different regions showd different degrees of defects,using chemical control technology,reasonable fertilization,disease prevention and control technology to make up for the deficiencies,promote grain production,increase income,and ensure food production safety.
