摘　　要：在平川区旱作区研究了不同施肥量对藜麦生物性状及产量的影响。结果表明,随着施氮量的增加,藜麦的株高、主穗长、生物产量、籽粒产量均得到了提高。尤其是施用藜麦专用肥(N-P_(2)O_(5)-K_(2)O为13-22-10),籽粒产量达3622.45 kg/hm^(2),与不施肥处理相比增产1377.55 kg/hm^(2),增产率61.36%,效果明显。The effect of different fertilizer amount on the biological traits and yield of buckwheat in dry farming region of Pingchuan District was studied.Results showed that plant height,main spike length,biological yield and grain yield of buckwheat were increased along with the increase in nitrogen application rate.Especial when specialty fertilizer of buckwheat was used(N-P_(2)O_(5)-K_(2)O,13-22-10),the grain yield was 3622.45 kg/ha which was 1377.55 kg/ha higher compared with that of the control,the yield increasing was 61.36%,which showed remarkable effect of increase in yield.
