科多四号、科多八号多穗青贮玉米品种引种及高产栽培技术研究

Introduction of multiple ear silage maize cultivars Keduo No.4 and keduo No.8 and their high yield cultivation technologies

经过 2年 (1999～ 2 0 0 0年 )的试验研究结果表明 ,科多四号、科多八号青贮玉米在景泰荒漠绿洲区有很好的适应性。鲜体产量科多四号为 13912 5kg/hm2 ,科多八号为 12 72 0 0kg/hm2 ,表现出很高的生产潜力和优良品质 。

Experimental results obtained from two years study(1999～2000) revealed that the introduced silage maize cultivars (Keduo No.4 and Keduo No.8)appeared a good adaptation to oasis in Jingtai county,Gansu province,The fresh yield was 139 125 kg/hm 2 for Keduo No.4 and 127 200 kg/hm 2 for Keduo No.8 respectively.It is concluded that these two cultivars could be extended into practice based on their high production potentiaL and fine quality.
