施用SODm增效剂对水稻茎蘖动态与节间形态的影响性研究

Studies on the Effect of SODm Synergist on Tillering Dynamics and Internode Morphology in Rice

通过设置不同SODm增效剂施肥量梯度,研究SODm增效剂调控水稻茎蘖动态和生长量以及节间形态等方面的作用,表明SODm增效剂可以促进水稻分蘖早生快发,提高植株分蘖能力和生长量,同时对于调控植株茎秆形态,减小低节位节间长度、增加低节位节间充实度等茎节性状具有明显的作用。

Through setting different SODm synergist gradients, the effect of SODm synergist on tillering dynamics and internode morphology in rice were studied. The results indicated that SODm synergist was bale to accelerate early and rapid emergence of tillers, and increase tillering capacity and growth amount, meanwhile, the SODm could also adjust plant morphology, shorten the internode length of low nodes and increase internode firmness significantly.
