为研究不同海拔对藜麦生长及产量的影响，为藜麦产业发展提供依据，以陇藜1号和陇藜4号为指示品种，在海拔分别为2 912、2 730、2 151、1 980 m的临潭县城关镇、天祝县松山镇、通渭县马营镇和平川区种田乡进行了多点试验。结果表明，总体上随海拔升高，藜麦灌浆期至成熟期延长，生育期也随之延长；随着播期的推迟，藜麦生育期呈缩短趋势，产量也降低。单株重、千粒重是直接影响藜麦产量的主要性状。产量变异系数陇藜1号 < 陇藜4号，说明陇藜1号综合性状表现良好，且产量稳定。

To study the effect of different altitudes on the growth and yield of quinoa and to provide reference for the development of quinoa industry, two quinoa varieties, Longli 1 and Longli 4, were grown in Chengguan Town of Lintan County, Songshan Town of Tianzhu County, and Maying Town of Tongwei County, Zhongtian Town of Pingchuan District with altitudes of 2 912, 2 730, 2 151 and 1 980 m a.s.l, respectively, thus multi-point experiments were carried out. The results showed that as the altitude increased, the grain filling stage to maturity was prolonged, and the growth period was also prolonged. With the delay of the sowing date, the growth period of quinoa was shortened, and the yield was also reduced. The plant weight and thousand-grain weight were the main traits that directly affected the yield of quinoa. The variation coefficient values of the yields ranked as Longli 1 < Longli 4, indicating that Longli 1 had ideal comprehensive performance and stable yield.
