我国玉米产业发展的国家需求是增产粮食，关键是提高单位面积产量，特别是提高单产的增长速度。实现这一目标亟需对玉米生产的耕作制度进行改革，主要是增加种植密度，东华北地区深松改土，黄淮海地区免耕直播和适当晚收获。玉米耕作制度的改革离不开机械化生产技术，同时也对玉米育种、栽培、植保等技术提出了发展需求。

The national demands of maize industry development in China is to increase grain yield， the key is to improve the yield per unit area,especially to raise the growth rate of yield. Achieving this goal will carry a more substantial reform to the farming system of maize production. The main measures are to increase planting density， sub soiling and soil improvement in the East North China,no-tillage direct seeding in the Huang-Huai region and appropriate late harvest. The reform of farming system is inseparable from mechanized production technology,and that proposes a long-term development demand to the techniques of maize breeding，cultivation and plant protection etc.
