以抗倒性不同的3个谷子品种冀谷31（高抗）、冀谷20（中抗）和张杂谷8号（不抗）为试材,均设土壤施用硅肥0（CK）、300、450、600和750 kg/hm2计5个处理,研究了施用硅肥对拔节期和抽穗期夏谷根系生长（单株根鲜重、单株根条数）以及对谷子产量的影响。结果表明：试验硅肥施用量范围内,施用硅肥对3个谷子品种拔节期、抽穗期的单株根鲜重和单株根条数,以及产量均无显著影响;不同谷子品种对拔节期和抽穗期的单株根鲜重及单株根条数均有极显著影响,对产量影响不显著。在拔节期,3个谷子品种的单株根鲜重顺序为张杂谷8号〉冀谷31〉冀谷20,其中,张杂谷8号和冀谷31与冀谷20间的差异均达到了极显著水平;单株根条数顺序为冀谷31〉张杂谷8号〉冀谷20,其中,冀谷31和张杂谷8号与冀谷20间的差异均达到了极显著水平。在抽穗期,3个谷子品种的单株根鲜重顺序为冀谷31〉张杂谷8号〉冀谷20,其中,冀谷31与张杂谷8号和冀谷20间的差异均达到了极显著水平;单株根条数顺序为冀谷31〉张杂谷8号〉冀谷20,其中,张杂谷8号与冀谷31和冀谷20间的差异均达到了显著水平,冀谷31与冀谷20间的差异达到了极显著水平。且试验施硅量范围内,抽穗期的单株根鲜重和单株根条数均多于拔节期。

Using foxtail millet varieties Jigu 31 （high resistance lodging） and Zhangzagu No. 8 （non-resistance to lodging） as the to lodging）, Jigu 20 （moderate resistance to materials, the effects of concentration of silicon varieties. At jointing stage, the root fresh weight of Zhangagu No. 8 was very significantly higher than that of Jigu 31 and Jigu 20. The root number of Jigu 31 was very significantly higher than that of Zhangzagu No. 8 and Jigu 20. At heading stage, the root fresh weight of Jigu 31 was very significantly higher than that of Zhangagu No. 8 and Jigu 20. The order of root number was Jigu 31 〉 Zhangagu No. 8 〉 Jigu 20, there were significant differences between Jigu 20. Zhangagu No. 8 and Jigu 31 and Jigu 20, and there was very significant difference between Jigu 31 and The root fresh weight and root number at heading stage were higher than those at jointing stage
