摘要:

为探究不同植物生长调节剂对甘薯苗期和农艺性状的影响,选取6-苄氨基嘌呤、赤霉素和萘乙酸3种植物生长调节剂,采用底施处理的方法开展其对甘薯薯苗生长的影响研究,通过室内实验研究甘薯薯苗的生根数、平均根长和根鲜重,通过田间试验研究甘薯生根数、甘薯块根膨大数和膨大率。结果表明:6-苄氨基嘌呤浓度为0.015 g(ai)/hm2时,块根膨大率与对照组相比存在显著性差异,膨大率高达37.02%;赤霉素浓度为1.50 g(ai)/hm2时,块根膨大数量、块根膨大率与对照组相比存在显著性差异,膨大率高达31.30%;萘乙酸浓度为0.015 g(ai)/hm2时,块根膨大率与对照组相比有显著性差异,膨大率高达32.24%。分析结果表明,3种植物生长调节剂对甘薯的生根、根长及根鲜重均有显著的促进作用。本研究将为进一步优化甘薯栽培管理提供理论依据和技术支持,有助于提高甘薯产量和品质,对甘薯的优质高产具有重要的意义。

Abstract:

Sweet potato is an important food crop and cash crop in China, and it has played an important role in ensuring China’s food security. Plant growth regulators not only increase crop yield, but also enhance stress resistance and improve quality, playing an important role in crop production. At present, there are relatively few researches on the application of plant growth regulators in sweet potato. To explore the effects of different plant growth regulators on the agronomic traits of sweet potato seedlings, three plant growth regulators, 6-benzylaminopurine, gibberellin and naphthalene acetic acid, were selected in this study, and their effects on sweet potato seedlings were studied by the method of bottom application. The results showed that the three plant growth regulators significantly promoted the rooting of sweet potato, and significantly promoted the root length and fresh weight of sweet potato. The research results would provide theoretical basis and technical support for further optimization of sweet potato cultivation management, help to improve sweet potato yield and quality, and promote the sustainable development of sweet potato industry.
