摘要
目前玉米生产机械化程度越来越高,玉米籽粒机收将是大势所趋,因此人们对玉米品种的选择也趋向于耐密植、抗倒伏和籽粒脱水快等优良性状.为了筛选出陇东旱塬区适宜的籽粒机收玉米品种,通过灰色关联度分析法对引进的 17 个玉米品种表型性状和籽粒机收适宜性进行综合评价.结果表明,和恒 5266 产量高,但是机收表现不理想;迪卡 159、先丰 9 号、先玉 1483、五谷 737 和新农育 6003 等 5 个品种综合表现良好,可以作为陇东旱塬区籽粒机收玉米品种贮备品种加以推广,尤其是五谷 737 产量高、抗性好、机收表现好,宜大力推广种植.
Abstract
As the degree of mechanization in maize production increases,mechanical harvesting of maize grains is becoming a major trend.Consequently,the selection of maize varieties tends toward those that are resistant to dense planting,lodging,and have quick grain dehydration characteristics.To select suitable grain maize varieties for mechanical harvesting in the dryland area of Longdong,a comprehensive evaluation was conducted on the phenotypic traits and mechanical harvesting suitability of 17 introduced maize varieties using the grey correlation analysis method.The results showed that,although Heheng 5266 had high yield,its mechanical harvesting performance was not ideal.Dika 159,Xianfeng 9,Xianyu 1483,Wugu 737,and Xinnongyu 6003 performed well overall and could be promoted as reserve varieties for grain mechanical harvesting in the dryland area of Longdong,especially Wugu 737,which had a high yield,good resistance,and excellent mechanical harvesting performance,and should be vigorously promoted for planting.
