| 摘 要： | 通过对4个谷子品种进行播期、密度与追肥复合因素试验研究其产量表现，结果表明影响产量最主要的因素是品种，其次是追肥量、密度，最后是播期。杂交谷子对密度、追肥量的需求大于常规品质，产量表现更好。旱地最佳种植播期为4月25日，最佳密度为16 000株/667 m2,追肥量为40 kg/667 m2。

| Abstract: | The yield performance of four millet varieties was studied under different compound factors such as sowing date, density and todressing.amount. Results showed that variety was the most important factor affecting the yield, followed by the amount of fertilizer, density and sowing date. For the given variety,higher density and fertilizer amount resulted in higher yield. The demand for density and fertilizer amount of hybrid millet was higher than that of conventional millet, leading to better yield. In dry land, the optimal planting date was found to be April 25, with density of 16 000 plants/667m2, and the top dressing amount of 40 kg/ 667 m2. |
