摘要:

为探究新型植物生长调节剂冠菌素和苯肽胺酸在水稻上的应用效果,于2024年开展田间大区试验,分别于水稻分蘖末期、破口前和灌浆期施药,对比分析各处理对水稻生长性状、产量构成及安全性的影响。结果表明:各处理均表现出良好的安全性;冠菌素和苯肽胺酸均可通过降低株高和基部节间长度来优化水稻株型,进而提高抗倒伏能力,其中冠菌素和圭百配配合处理效果最佳;苯肽胺酸处理可明显增加有效穗数,提高结实率和千粒重,产量较对照增加29.8%~30.2%;冠菌素处理可有效增加每穗粒数,其中3次施用冠菌素处理增产效果最优,较对照增产40.0%。综上,冠菌素和苯肽胺酸在提升水稻产量和增强抗逆性方面表现突出,具备替代传统植物生长调节剂的应用潜力。

Abstract:

To explore the application effects of the novel plant growth regulators coronatine(COR)and phthalanilic acid(PA)on rice,a field plot trial was conducted in 2024. Applications were made at the late tillering stage,pre?heading stage,and grain-filling stages,respectively. The effects of different treatments on rice growth traits,yield components,and safety were compared and analyzed. The results showed that all treatments exhibited good safety. Both COR and PA could improve rice plant architecture by reducing plant height and the length of basal internode,thereby enhancing lodging resistance,with the combined treatment of coronatine and Guibaipei showing the best performance. PA treatments significantly increased the number of effective panicles,improved seed-setting rate and 1 000-grain weight,resulting in a yield increase of 29.8%-30.2% compared with the control(CK). COR treatments effectively increased the number of grains per panicle,and among them,the treatment with 3 applications of coronatine achieved the highest yield increase,reaching 40.0% compared with the control. In conclusion,COR and PA demonstrated outstanding performance in increasing rice yield and enhancing stress resistance,demonstrating potential to replace traditional plant growth regulators.
