在甘肃省不同生态区对16个耐密玉米品种进行了密植试验。结果表明，玉米品种先玉335、陇005、陇006、武001对环境的分辨率较高，高产但不太稳产。酒002、武003、武002、武005有较好的适应性，对环境的分辨率较低，相对稳产。临001、酒001、郑单958对环境的分辨率较高，产量表现低且不稳。在武威、张掖、酒泉、庆阳点适宜种植中晚熟高密品种，可推广密植品种及其栽培技术，临夏、平凉地区在选择耐密品种时要充分考虑品种的生育期、适应性和栽培技术。

The density test of 16 density tolerance corn variety are planted in different ecological regions of Gansu province. The result shows that Xianyu 335， long 005， long 006 and Wu 001 have high resolution to the environment， high yield but not very stable . Jiu 002， Wu 003， Wu 002 and Wu 005 has better adaptability to the environment， the resolution is low and relativelystable. Lin 001， Jiu 001， Zhengdan 958 have high resolution to the environment， the yield performance are low and unstable. It is suitable to be grown late density varieties in Wuwei， Zhangye， Jiuquan， Qingyang， so we can promotion the density varieties and its cultivation technology . It is choose to be grown density tolerance corn variety which need to fully consider the growth period， the adaptability and cultivation techniques of varieties in Linxia， Pingliang area .
