摘要
北京市在实施玉米高产创建活动中,根据实施目标和玉米生产上存在的主要技术问题,确定了以增密为核心的"一增二改三提高"技术方案,集成建立了新的玉米高产栽培技术体系,在示范区强化推广应用。2年共建立示范区7114.00hm2,实现了单位面积产量的稳定跨越和总产增加,为进一步提高玉米产量水平开辟了一条新的技术途径。实现了北京市玉米单产自2007年起从过去的全国中下水平上升并稳定保持在中上的水平。
Beijing in carrying out productive activities of the corn create, according to implement the goals and corn production were the main technical questions, identify the key to increase the technology solutions, integration of new corn high technology system, cultivated, In promoting the application of strengthened demonstration area. Established demonstration area 7 114.00 hm^2 in 2 years, the yield per unit area on the stability of the cross and fighting to further enhance the level of maize output opened up a new technical means. Achieved since Beijing corn the yield per unit area 2007 up from the past half of the country level and stability remain on the rise in level.
