太原地区夏玉米高产试验

Study on High Yield of Summer Maize in Taiyuan Region

试验表明 ,极早单 2号、极早单 4号抗病、丰产 ,产量超过 6 0 0 0kg/hm2 ,为太原地区夏播玉米优良品种。其中 ,极早单 2号植株高大粗壮 ,叶片宽阔浓绿 ,穗粗而长 ,产量为 6 372 .15kg/hm2 ,是目前太原地区夏播玉米最高产量。地膜覆盖、玉米磁衣处理可缩短夏玉米生育期 。

The test shows that the yield of Jizaodan 2,Jizaodan 4 were more than 6 000 kg/hm 2.At present,they are appropriate varieties in Taiyuan region.Of which,Tizaodan 2 had high and strong plant,wide and dark green leaves,wide and long ears,and its yield was 6 372.15kg/hm 2,the highest yield of summer maize in Taiyuan.It can shorten maize growth time and increase the yield to use plastic film and maize growth regulator in summer maize culture.
