摘　　要：为了给青贮玉米品种的选择提供一定的参考,笔者分析了青贮玉米品种试验存在区域布局、试点分布不合理,品种类型缺乏全面定位,育种水平不高等问题,指出青贮玉米品种未来的发展方向定位于粮饲兼用型是毋庸置疑的,但专用青贮玉米同样有其生存的空间。分析表明,应着力开展专用青贮玉米品种试验,合理布局,在条件成熟时可在普通玉米生产试验中发现青贮产量高的品种作为其特点予以关注。Silage Maize trial was currently in the preliminary stage of development. There were some problems in silage maize trial, such as unreasonable regional distribution, unreasonable pilot distribution, the shortage of comprehensive position of variety type, and the low breeding level. The future development orientation of silage maize should be no doubt cereal silage maize type, but the special silage maize varieties had also space for planting. The pilot system should strive to carry out special silage maize varieties trials and to conduct rational distribution. In the future, more attentions might be paid to the common maize with high silage yield found in common maize production trial.
