玉米是重要的粮食作物之一,又是工业原料和良好的饲料。发展玉米生产对国民经济具有重要的作用。然而,我师的玉米生产虽有三十年的历史,但生产水平不高,单产低,经济效益差,而且面积还有继续缩小的趋势。这样,直接影响了畜牧业生产的发展。为了使玉米生产能得到迅速的恢复和发展,必须寻求一套投资少、产量高的农艺措施,提供最优生产条件,制定出 Corn is one of the important food crops, but also industrial raw materials and good feed.

In order to enable the rapid recovery and development of corn production, we must seek a set of agronomic measures with low investment and high yield, provide optimal production conditions,
