玉米是克州主要粮食作物之一,克州山区玉米主栽品种SC-704和石玉905已经种植多年,但还没有储备好理想的替代品种和后备接班品种,这将严重制约我州粮食生产持续稳定发展。为了加快克州山区玉米新品种的更新换代速度,提高良种覆盖率,为粮食生产准备优良的后备品种资源,2010年我站引进玉米新品种美玉7438参与试验,通过试验示范,表明该品种高产、优质,活秆成熟。平均产量达1.5万kg/hm2以上,秸秆产量7.5万~9.0万kg/hm2。
Corn is one of the staple food crops in Kezhou. The main cultivars of SC-704 and Shiyu 905 in the mountainous areas of Kezhou have been planted for many years. However, the ideal alternative varieties and reserve succession varieties have not been stored, which will seriously restrict the grain production Sustained and steady development. In order to speed up the replacement rate of new varieties of maize in mountainous areas of Kezhou, improve the coverage of improved varieties and prepare excellent reserve resources for food production, in 2010, I introduced the new maize variety Meiyu 7438 to participate in the experiment. Through experiments and demonstrations, High-quality, live stalks mature. The average output of 15,000 kg / hm2 above, straw output of 75,000 to 90,000 kg / hm2.
