摘　　要：试验研究黄淮海平原优质玉米生长发育特性及产量形成规律结果表明,与当地普通玉米品种相比,优质蛋白玉米品种“中单94 0 9”和高油玉米品种“高油115”生育期天数(约10 4～10 5d)基本与“冀丰5 8”相似,但比“莱玉2”生育期短。玉米营养生长和生殖生长阶段干物质积累增长以“中单94 0 9”和“冀丰5 8”最显著,但经济产量优质蛋白玉米品种“中单94 0 9”高于“冀丰5 8”,而与“莱玉2”相近。优质玉米赖氨酸含量均明显高于普通玉米。Field experiment on the growth development and yield formation of the high quality maize shows that the numbers of the whole growing days of the high quality maize variety‘zhongdan 9409’and ‘gaoyou 115’are similar to those of the local variety ‘jifeng 58’,but significantly less than ‘laiyu 2’.There are no significant differences in the accumulated dry weight between the high quality maize and local maize variety,but the economic production of the variety ‘zhongdan 9409’is higher than that of ‘jifeng 58’. The lysine content of the high quality maize is significant higher than that of local maize variety.
