摘　　要：本试验以丰油730油菜为材料,通过在油菜不同生长时期施用不同浓度的多效唑,探讨多效唑在油菜增产和抗倒方面的最佳施药时间与最佳用量。结果表明,不同浓度多效唑处理之间存在着明显的产量差异,用100 mg/L多效唑处理的油菜综合性状优异,产量最高;在不同时期施用多效唑处理也存在明显的差异,以薹高10 cm时喷施效果最好,经济性状较优,平均产量最高。In this experiment,different concentrations of paclobutrazol were applied in different growth periods of rape to explore the optimal application time and rate of paclobutrazol in terms of yield increase and lodging resistance.The results showed that there were obvious differences in yield among of different concentration treatments of paclobutrazol.The rape treated with 100 mg/L paclobutrazol had excellent comprehensive traits and the highest yield.The application of paclobutrazol in different periods also had obvious differences,when the height of rape bolting was 10 cm,the application effect was the best,the economic character was better,and the average yield was the highest.
