摘要
通过分析陕北农作物的结构和产量情况 ,认为充分发挥玉米增产潜力大的优势 ,努力提高玉米单产 ,实现高产稳产 ,提高人均产粮水平 ,是尽块实现退耕还林 (草 )的保证措施之一 。
The basic situation of crop productivity in loess hilly and gully region has been analyzed. The results show that raising corn yield is very important. It is one of ensuring measures to become self sufficient in this area and to change land on the slope into forest land or grassland as quickly as possible.
