试验结果表明:不同播种期对荞麦主要性状有极显著影响。播种期推迟,生育期缩短,株高、单株分枝数、花簇数、簇花数减少,但结实率升高,单株粒数和粒重随着增加,推迟到一定时候单株粒重和粒数又呈下降趋势。 The results showed that different sowing dates had the most significant effect on the main characters of buckwheat. The sowing date was delayed and the growth period was shortened. The plant height, the number of branches per plant, the number of flower clusters and the number of tufts decreased but the seed setting rate increased. With the increase of grain number and grain weight per plant, Weight and grain number showed a downward trend.
