| 摘 要： | 设置5种化控制剂处理,研究了拔节期前喷施不同化控制剂对优质稻泰优398茎秆配置、抗倒伏特性及产量的影响。结果表明,5种化控制剂喷施后株高均显著降低但对产量没有显著影响,其中,4种制剂喷施后能够缩短基部倒4、倒5节间长度,喷施25%多效唑悬浮剂和5%烯效唑可湿性粉剂能显著增加植株推阻和倒3节抗折力,从而增强植株抗倒伏能力。在本试验条件下的5种化控制剂中,在拔节期前喷施25%多效唑悬浮剂和5%烯效唑可湿性粉剂对优质稻泰优398的抗倒伏能力提升效果较好。

| Abstract: | Five treatments of anti-lodging preparations were used to study the effects of spraying anti-lodging preparations just before jointing stage on stem configuration, lodging resistance and grain yield of the high-quality hybrid rice Taiyou 398. The results showed that spraying any of the anti-lodging preparations reduced the plant height significantly but did not affect the grain yield significantly. Among five anti-lodging preparations, four shortened the length of the 4th and 5th internodes from the top, and the treatments of MET(25%) and S-3307(5%) significantly increased the plant push resistance and break resistance of the 3 rd internode from the top, resulting in improvement of the lodging resistance. It is concluded that the MET(25%) and S-3307(5%) have a better effect on improving the lodging resistance of the high-quality hybrid rice Taiyou 398 under the conditions of this experiment. |
