【摘要】 为解决生姜切块育苗壮芽一致性低的生产问题，本研究以生姜金凤1号为试材，以清水为对照，采用6种植物生长调节剂单剂，并选取其中具有潜在协同作用的调节剂进行二元或三元复配，形成16种复配组合，共设23个处理，研究各处理对姜块发芽率、芽长、芽粗、发芽势及发芽指数等指标的影响，进一步优化切块生姜催芽技术。结果表明，0.5 mg·L^-1乙烯利（ETH）单剂及其与2 mg·L^-1吲哚乙酸+0.2 mg·L^-1油菜素内酯的复配组合（ETH+IAA+BR）对芽体生长均具有显著促进作用，芽长分别达13.66、12.68 mm，芽粗分别达8.25、8.27 mm，且发芽率均达100%；硫脲与乙烯利复配处理（TU+ETH）发芽势达100%，发芽指数为2.50，显著提升发芽一致性。但赤霉素（GA₃）单剂及含GA₃的复配处理对生姜发芽均具有抑制作用，芽长仅为3.55～5.42 mm，发芽率最低为66.67%。通过熵权TOPSIS法多指标综合评价进一步证实，ETH+IAA+BR处理（相对接近度0.907）、TU+ETH处理（相对接近度0.869）位于前列，综合促芽效果好，而GA₃处理的相对接近度仅为0.108，抑制效应显著。综上，乙烯利及其复配组合可作为切块生姜高效催芽方案，为切块生姜壮芽率提供了科学依据与技术支撑，建议生产中优先选用0.5 mg·L^-1乙烯利单剂或2 g·L^-1硫脲+0.5 mg·L^-1乙烯利复配组合，并避免使用GA₃类药剂。更多还原

【Abstract】 This study utilized ginger cultivar Jinfeng No. 1 as the experimental material, aiming to address the production problem of low uniformity of robust buds in ginger rhizome block seedling raising. To optimize the germination technology of cut ginger rhizomes, high-efficiency plant growth regulators in both single-agent and combined formulations were screened. Initially, six plant growth regulators were evaluated individually, those with potential synergistic effects were further formulated into binary or ternary compound combinations, resulting in 16 mixed formulations. A total of 23 treatments were established, including the single agents, compound combinations, and water as control, to investigate their effects on germination rate, bud length, bud thickness, germination potential, and germination index of ginger rhizome blocks. The results indicated that both the application of 0.5 mg · L^-1 ethephon（ETH）alone and its ternary combination with 2 mg · L^-1 indoleacetic acid（IAA）and 0.2 mg · L^-1 brassinolide（BR）（ETH+IAA+BR）significantly promoted bud growth. The two treatments achieved bud lengths of 13.66 and 12.68 mm, respectively, with corresponding bud thicknesses reaching 8.25 and 8.27 mm, and both attained 100% germination rate. The binary combination of thiourea and ethephon（TU+ETH）achieved 100% germination potential and a germination index of 2.50, which significantly improved the uniformity of germination. In contrast, gibberellin（GA₃）applied alone or in compound formulations exhibited inhibitory effects on ginger germination, with bud lengths ranging from 3.55 to 5.42 mm and the lowest germination rate being only66.67%. The multi-index comprehensive evaluation based on the entropy weight TOPSIS method further demonstrated that the ETH+IAA+BR treatment（relative closeness coefficient: 0.907）and the TU+ETH treatment（relative closeness coefficient: 0.869）ranked highest, exhibiting favorable overall sprouting performance, whereas the GA₃ treatment yielded a relative closeness coefficient of only 0.108, indicating a pronounced inhibitory effect. In conclusion, ethephon and its compound combinations can serve as efficient germination-promoting schemes for cut ginger rhizomes, providing scientific basis and technical support for improving the rate of robust buds in ginger production. It is recommended that in production practice, priority should be given to the application of either 0.5 mg·L^-1 ethephon alone or the compound combination of 2 g·L^-1 thiourea plus 0.5 mg·L^-1 ethephon, and the use of GA₃-based agents should be avoided.更多还原
