矮壮素对大麦的影响因类型、品种而异,二棱大麦大多不敏感,没有应用价值,六棱大麦大多敏感,四棱大麦介于两者之间,矮壮素抑制正在伸长的节间,使节间缩短,薄壁组织细胞层次增加,茎壁加厚,从而增加抗倒力,施用时间以拔节前第一节开始伸长时喷施为宜,矮壮素有延迟大麦成熟趋势,其程度因浓度及品种而异,又会引起粒重下降,但远比倒伏植株粒重的降低为小,所以,对容易倒伏的大麦喷施矮壮素有增产效果。
The effects of CCC on barley vary with different types and varieties. Most of the two barley cultivars are insensitive, have no application value, are mostly sensitive to hexagonal barley, and are surrounded by four-rowed barley. CCC inhibits the growing section Between the internode shortening, parenchyma cells increased, thickened stem wall, thereby increasing the anti-lodging, the application time before the beginning of elongation before the start of spraying spraying, CCL delayed barley ripening trend , The degree of which varies according to the concentration and the variety, but also causes the decrease of the grain weight, but it is much smaller than the reduction of the grain weight of the lodging plants. Therefore, the application of the CCC to barley which is prone to lodging has the effect of increasing yield.
