为了引进适宜汨罗市种植的玉米新品种,选择了湘康玉1号等10个新品种,与当地的主栽品种临奥一号进行田间品比试验。结果表明:科玉6号的实际产量显著高于对照,比对照增产34.3 kg/666.7m2;福单2号、正大999和金湘369与对照的实际产量处于同一水平,均在624 kg/666.7m2以上;其余6个品种均比对照显著减产。这说明,科玉6号比临奥一号更适宜当地的气候及地理环境,可作为丘岗旱地玉米主推品种;福单2号可作为平湖区玉米替代品种;临奥一号还可继续作为当家品种种植;金湘369、正大999的实际产量与对照相当,可以选择性种植;其余品种建议续试或不宜推广。
In order to introduce new maize suitable for planting in Miluo City, 10 new varieties, such as Xiangkang-1, were chosen to carry out the field ratio test with the local cultivated variety Lin-1. The results showed that the actual yield of Keyu 6 was significantly higher than that of the control, 34.3 kg / 666.7 m 2 higher than the control; the actual yields of Fudan 2, Zhengda 999 and Jinxiang 369 were at the same level as the control, both at 624 kg / 666.7 m2 above; the remaining six varieties significantly reduced compared with the control. This shows that Keyu 6 is more suitable for the local climate and geographical environment than Pro-1, which can be used as the main push varieties of corn in the mound of dryland; Fudan 2 can be used as alternative varieties of maize in Pinghu District; Pro-1 can continue to be the When the species of planting; Jinxiang 369, Chia Tai 999 actual output comparable with the control, you can selectively grow; other varieties recommended for testing or should not be promoted.
