以超级杂交稻培杂泰丰和华优86为材料,在旱育秧和湿润育秧条件下,研究了专用壮秧剂对超级稻秧苗生长的影响。结果表明:壮秧剂可显著提高超级杂交稻旱育秧的成秧率和出叶速度;不论是湿润育秧还是旱育秧,壮秧剂对秧苗均具有显著的矮化作用,并可显著增加秧苗的茎基宽、单位高度干重和叶片叶绿素含量;壮秧剂还可明显提高旱育秧秧苗的抗逆能力,秧苗叶片的蛋白质含量、脯氨酸含量和苯丙氨酸解氨酶(PAL)活性均显著高于对照。
Super hybrid rice cultivar Taifeng and Huayou 86 were used as materials to study the effects of special seedling enhancer on the growth of super rice seedling under the conditions of drought-tolerant and wet seedling. The results showed that the strong seedling enhancer could significantly increase the seedling emergence rate and leaf-out rate of the super-high-yielding hybrid rice in drought-tolerant seedlings. Both wet-growing and dry-raising seedlings had strong dwarfing effect on seedlings and significantly increased seedling growth Stem width, dry weight per unit height and leaf chlorophyll content. Seedling enhancer could also significantly increase the stress resistance of seedlings of dry-seedling seedlings, the protein content, proline content and PAL activity of seedling leaves Were significantly higher than the control.
