摘　　要：为提高紫云英的种子产量,以信紫1号为供试材料,在紫云英现蕾期叶面喷施芸苔素内酯(BR),对其主茎不同花序位的花序结实性状和种子产量进行测定。结果表明,与清水对照相比,BR处理基部、中部、顶部花序位的花数较对照分别提高19.61%、11.86%、20.99%,且均与对照差异显著;荚数较对照分别提高30.22%、34.43%、60.00%,且均与对照差异显著;结荚率较对照分别提高9.85、8.63、4.56百分点,且均与对照差异显著;结实率较对照分别提高1.58、1.08、0.53百分点,且均与对照差异不显著;籽粒数较对照分别提高7.72%、5.71%、13.11%,但均与对照差异不显著;粒质量较对照分别提高24.92%、17.54%、63.16%,且均与对照差异显著。现蕾期叶面喷施BR主要是通过提高其荚数和粒质量来提高最终种子产量,而对籽粒数的影响不明显。The effect of foliar spray brassinolide on Chinese milk vetch seed number and seed quality at squaring stage were studied to provide references for improving yield through use of chemical regulation. Xinzi 1 was chosen for test material. Foliar spraying brassinolide(BR)was performed at the squaring stage, while spraying water as control. During the flowering period, the setting characteristics of inflorescence at the basal, central, and apical inflorescence layers in the main stem were investigated. At harvest, the yield and yield components were determined using conventional methods. The results showed that the flower number in the basal, central and apical inflorescence layers increased by 19.61%、11.86% and 20.99%, respectively, compared with that of the control group, which was significantly different from that of the control group. The pod number in the basal, central and apical inflorescence layers increased by 30.22%、34.43% and 60.00%, respectively, compared with that of the control group, which was significantly different from that of the control group. The pod set rate in the basal, central and apical inflorescence layers increased by9.85, 8.63 and 4.56 percentage points, respectively, compared with that of the control group, which was significantly different from that of the control group. The seed set rate in the basal, central and apical inflorescence layers was increased by 1.58, 1.08 and 0.53 percentage points, respectively, compared with that of the control group, which was no significantly different from that of the control group. The seed quality in the basal, central and apical inflorescence layers increased by 7.72%、5.71% and 13.11%, respectively,compared with that of the control group, which was no significantly different from that of the control group. The seed quality in the basal, central and apical inflorescence layers increased by 24.92%、17.54% and 63.16%, respectively, compared with that of the control group, which was significantly different from that of the control group.
