摘要： 为了研究新型生长调节剂对棉花赘芽生长及产量性状的影响,探索棉花规模化种植过程中抑制赘芽滋生、简化整枝管理的新技术。在大田条件下设置了多铃专家、艾氟迪与生长调节剂缩节胺(DPC)的对比试验,对棉花植株形态、赘芽生长、成铃空间分布以及产量进行了研究。结果表明：喷施多铃专家、艾氟迪后,对棉株上部主茎节间平均长度和中上部果枝平均长度的生长抑制作用弱于缩节胺；单株赘芽鲜重和干重均显著小于缩节胺处理,单株赘芽鲜重为对照的54.8%和49.4%,单株赘芽干重为对照的53.2%和54.8%,单株赘芽总长度为对照的69.0%和58.1%；单株成铃数比对照高7.0%和12.3%,产量分别比对照高12.6%和10.2%,多铃专家处理提高了棉株内围铃数,艾氟迪处理则主要增加了棉株外围铃数,两者还有增加主茎叶腋处桠铃的趋势。

Abstract: The paper aims to study the effect of different plant growth regulators on redundant vegetative shoots growth and yield characteristics of cotton and explore new technology for inhibiting redundant vegetative shoots growth and simplifying the management of pruning in large scale cotton cultivation. The contrast test under field condition was conducted with three plant growth regulators (Duolingzhuanjia, AFD and DPC) to study the effect of different plant growth regulators on plant morphology, redundant vegetative shoots growth, spatial distribution of bolls and yield. The results showed that the inhibition effects of Duolingzhuanjia and AFD on average length of the upper main stem and the middle-upper fruit branch were weaker than that of DPC. The dry and fresh weight of redundant vegetative shoot per plant under Duolingzhuanjia and AFD treatments were significantly less than that under DPC treatment. Compared to DPC treatment, the fresh weight of redundant vegetative shoot per plant under Duolingzhuanjia and AFD treatments were 54.8% and 49.4% of that of the DPC treatment , the dry weight were 53.2% and 54.8% of that of the DPC treatment, the total length were 69.0% and 58.1% of that of the DPC treatment, the bolls per plant were 7% and 12.3% higher than that of the DPC treatment, and the yield were 12.6% and 10.2% higher than that of the DPC treatment. Duolingzhuanjia could increase internal bolls of plant and AFD could increase external bolls, they all had a trend for increasing the small bolls of main stem leaf axils.
