    摘要:

    为筛选抗倒伏性强、适宜机械化收获的谷子品种,以抗倒性不同的23个谷子品种(系)为材料,通过调查分析株高、单株鲜重、根干重、机械强度、倒伏级别等与倒伏系数之间的关系,评价了各个参试品种的抗倒伏性。结果表明,植株根干重、机械强度与倒伏系数关系最密切,根干重越大,茎秆的机械抗折力越大,从而机械强度越大,谷子越抗倒伏,为选育抗倒伏性强的谷子品种提供了理论基础。

    Abstract:

    In order to screen varieties suitable for mechanized harvest, 23 millet varieties with different lodging resistance were used as materials. By investigating various traits of varieties, the relationship between plant height, fresh weight per plant, root dry weight, mechanical strength and lodging coefficient was analyzed, and the lodging resistance of the tested varieties was evaluated. The results showed that the root weight and mechanical strength of the plant were most closely related to the lodging coefficient. The greater the root dry weight, the greater the stem bending resistance, the greater the mechanical strength of the stem, the stronger the lodging resistance of millet, the more suitable for mechanized harvesting, which provided a theoretical basis for breeding millet varieties with strong lodging resistance.
