摘要： 为了探讨青贮玉米（Zea mays）在高寒牧区种植的可行性，在海拔2700 m高寒生态区开展了青贮玉米生产性能的初步研究。结果表明：终霜过后到初霜出现，铺地膜种植青贮玉米，生长天数102 d，早熟品种能进入抽雄期，种植密度15.75万株·hm-2，植株高度202.1~269.6 cm，鲜草产量83329~95305 kg·hm-2，干草产量31888~41509 kg·hm-2。在高寒牧区铺地膜种植青贮玉米是完全可行的。金穗3号、中玉9号、郑单958和龙源3号品种综合表现优良，可作为该地区推广的主要品种。

Abstract: In order to study the feasibility of planting silage maize in alpine region, the production performance of silage maize was investigated in the Qilian county of Qinghai Province with the altitude of 2700 m. Results showed that the growth of silage maize was normal with covering mulching film during frost. The average growth period of silage maize was 102 days. Some early maturity varieties had anthesis stage. The plant heights, fresh and dry weights of tested varieties under the planting density of 157,500 plants·hm-2 were about 202.1~269.6 cm, 83,329~95,305 and 31,888~41,509 kg·hm-2, respectively. These results suggested that planting silage maize with covering mulching film in this region was completely feasible. And the varieties of Jinsui 3, Zhongyu 9, Zhengdan 958 and Longyuan 3 were recommended for planting in alpine region.
