摘要： 摘 要：为探明多效唑对谷子优质品种‘晋谷21号’的调控效果，提高‘晋谷21号’的抗逆性能，在3叶期、6叶期、9叶期三个时期，以0.2%、0.3%、0.4%、0.5%、0.6% 五个浓度作了喷施多效唑试验。结果表明：喷施多效唑后，对‘晋谷21号’谷子下部节间长度（1~9节）有明显的抑制作用，并减少节间数量，使株高明显降低；喷多效唑的最佳时期为谷子出苗后9叶期；喷施多效唑的最佳浓度为0.4%~0.5%；喷施多效唑后不会影响‘晋谷21号’的谷子产量和小米品质。

Abstract: Abstract: In the 3 period, spraying Paclobutrazol proved on millet varieties of JinGu 21 regulation, improved the stress resistance of JinGu 21, with 5 concentration testing. The results show that: after spraying Paclobutrazol, the JinGu 21's internode length (1-9) has obvious inhibiting effect, and reduce the number of internode, the plant height decreased significantly; the best period of spraying Paclobutrazol for millet is 9 leaves stage after seedling; the optimal concentration of Paclobutrazol is 0.4-0.5%; JinGu 21 millet's yield and quality did not affect.
