玉米是我区粮食生产上的主要种植作物,常年种植面积35万亩以上,1992年总产量1.28亿公斤,平均单产341.9公斤。1993年,为进一步探索提高我区玉米单产的新途径,实现全区玉米总产量的新突破。我们在多年试验、示范紧凑型玉米杂交种取得一定成效的基础上,利用我区14万亩吨粮田开发项目为龙头,努力在全区普及推广和开发利用紧凑型玉米杂交种,使全区紧凑型玉米杂交种的推广面积达到近30万 Maize is the main crop for grain production in our region. The perennial planting area is more than 350,000 mu. In 1992, the total output was 128 million kilograms, with an average yield of 341.9 kilograms. In 1993, in order to further explore new ways to improve corn yield in our region, realize a new breakthrough in total corn output. Based on years of experiments and demonstrations of certain achievements in compact corn hybrids, we have used 14 million mu of grain field development projects in our district as a leader to popularize and promote the use of compact maize hybrids throughout the region, The popularization of compact maize hybrids has reached nearly 300,000
