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。
In implementing the high-yielding corn production activity in Beijing, according to the implementation target and the main technical problems existing in the corn production, the “one-for-two-two-three-improvement” technical solution with densification as the core was established and the new corn was integrated High-yielding cultivation technology system, in the demonstration area to strengthen the promotion and application. In the past two years, a total of 7114.00hm2 of demonstration area has been established, which has realized a steady leap in output per unit area and an increase in total output, opening up a new technological approach for further raising corn output. The corn yield in Beijing has been rising from the past middle and lower levels in the country since 2007 and has remained stable at the upper level.
