玉米是延庆区的主要粮食作物,主要种植品种是郑单958、中单28、京科968、农大108、农华101、京单28、纪元一号及京科528等,种植品种多且杂,不利于玉米标准化生产。主栽品种郑单958增产效果不明显,产量不稳定,影响了全区玉米产量的提高。玉米品种京科968是一个品质优良的中晚熟品种,该品种适应范围广、品质好、产量高,具有高产、优质、多抗、稳产的特点。京科968在区域试验及生产试验中表现突出,通过小面积示范,探索其高产栽培技术。
Corn is the main food crop in Yanqing District. The main varieties are Zhengdan 958, Zhongdan 28, Kekei 968, Nongda 108, Nonghua 101, Jingdan 28, Jianyuan 1 and Jingke 528, , Is not conducive to the standardization of corn production. The main variety Zhengdan 958 yield effect is not obvious, the output is unstable, affecting the increase of corn yield in the region. Corn varieties Beijing Branch 968 is a good middle-late maturing varieties, the variety to adapt to a wide range of good quality, high yield, with high yield, high quality, multi-resistance, stable yield characteristics. Beijing Branch 968 in the regional trials and production trials outstanding performance, through a small area demonstration to explore its high-yielding cultivation techniques.
