玉米化控技术在逆境条件下和高产再高产条件下更能显示其潜力。本文探讨玉米单产 90 0 0～ 12 0 0 0kg hm2 、12 0 0 0～ 150 0 0kg hm2 技术措施。其技术关键是 :在正常高产栽培技术的基础上 ,选择适宜的地块和品种 ,增肥增密 ,在生育中期喷施一次玉米壮丰灵 ,从而实现高产、稳产、优质、高效的目的。为我省玉米大面积、大幅度提高单产提供参考 Maize chemical control technology in adversity conditions and high yield and more productive conditions to better show its potential. This paper explored the technical measures of yield per hectare of 90 000 ~ 1200 kg hm2 and 120 000 ~ 150 000 kg hm2. The key technology is: on the basis of normal high-yielding cultivation techniques, select suitable plots and varieties, increase fertilizer and densification, and spray corn at one growth stage to achieve high yield, stable yield, high quality and high efficiency. For our province a large area of ​​corn, a substantial increase in yield to provide a reference
