| 摘 要： | 以超级稻品种连粳7号为材料,研究了不同植物生长调节剂对机插水稻抽穗后株高、节间长度、茎秆性状及产量的影响。结果表明,喷施矮壮丰和劲丰能够增加机插水稻实粒数、结实率和千粒重,矮壮丰75 m L/667 m~2的处理较对照增产49.63 kg/667 m~2;喷施多效唑和烯效唑可以显著降低机插水稻株高,提高茎秆的抗折力,结实率和千粒重高于对照,但由于实粒数大大低于对照,最终没有达到增产的目的。

| Abstract: | The effects of plant growth regulators on plant height, internode length,stem characters and yield after heading of mechani-cal transplanted rice, using super rice variety Liangeng 7 as material. The results showed that aizhuangfeng and jinfeng could increase filled grains, seed setting rate and thousand grain weight. The yield of treatment which spraying 75 mL/667 m 2 aizhuangfeng was 49.63 kg/667 m2 higher than the control. Although paclobutrazol and uniconazole could reduce the plant height, improve the culm breaking-resistant strength and increase the seed setting rate and thousand grain weight, however the filled grains of the treatments of paclobu-trazol and uniconazole were significantly lower than that of the control, and finally did not achieve the purpose of increasing yield. |
