摘　　要：比较分析了1次和2次叶面喷施烯效唑对秋芝麻植株生长及产量性状的影响。结果显示:叶面喷施烯效唑使秋芝麻株高变矮,始蒴高度降低,果轴长度变短,结蒴密度、单株蒴果数、每蒴粒数和千粒重增加,进而使产量较空白对照(CK)显著增加,且2次喷施的效果优于1次喷施的;秋芝麻1次和2次喷施烯效唑较CK分别增产11.10%和11.75%;叶面喷施烯效唑对上部蒴果的影响最为显著,上部蒴果的每蒴粒数和千粒重均较CK显著增加。The effects of foliage spraying uniconazole once or twice on the plant growth and yield characters of autumn sesame were compared and analyzed. The results showed that foliage spraying uniconazole shortened the plant height,the first capsule height and the capsule axis length of autumn sesame,increased the density of capsules,the number of capsules per plant,the number of seeds per capsule and the 1000-grain weight,and then increased the yield significantly as compared with the blank control. The effect of two-time spraying uniconazole was better than that of one-time spraying,and their yield-increasing rate was11.75% and 11.10%,respectively. The effect of foliar spraying uniconazole on the upper capsules was the most significant,and the number of seeds per capsule and the 1000-grain weight of upper capsules were significantly higher than those in the control.
