摘　　要：为了探索藜麦合理轮作,找到适宜的前茬作物,本研究设置了小麦、大麦、油菜等9种作物进行相应轮作,以藜麦连作为对照,分别于现蕾期和成熟期测定藜麦生长状况及产量。结果表明,与藜麦轮作相比,不同前茬处理的藜麦在叶片颜色、花色、顶叶颜色、叶片长度、叶片宽度、叶柄长度、茎粗、花序长度、穗长、穗宽、千粒重和单株产量方面均无显著差异,但是在株高、有效分枝数、第一有效分枝高度、有效穗数和小区产量方面稍有差异。其中,油菜茬、小麦茬和马铃薯茬的单株产量和小区产量均高于藜麦轮作处理,适于作为藜麦前茬作物。In order to explore rational rotation of quinoa, nine crops, such as wheat, barley and rape, were selected for rotation. The continuous quinoa was used as the control, the growth status and yield of quinoa were measured at budding stage and mature stage. The results showed that, compared with quinoa rotation, there were no significant differences in leaf color, flower color, parietal leaf color, leaf length, leaf width, petiole length, stem diameter, inflorescence length, ear length, ear width, 1000-grain weight and yield per plant among different previous crop treatments. But there were slight differences in plant height, effective branch number, first effective branch height, effective panicle number and plot yield. The yield per plant and plot of rape stubble, wheat stubble and potato stubble were higher than that of quinoa rotation, so it was suitable to be used as previous crop of quinoa.
