摘要: 为探究退化百合(Lilium spp.)种球复壮的关键调控技术,以百合退化种球为材料,采用正交试验设计,从促萌预处理与栽培管理两个阶段系统研究温度调控、植物生长调节剂及生物制剂等因素对种球萌发及后期生长的影响,筛选促进种球复壮的关键技术组合。结果表明,促萌阶段各因素对种球萌发率的影响程度由大到小依次为变温处理、植物生长调节剂、生物制剂,其中适宜的变温处理可显著提高种球萌发率,200 mg/L NAA处理对萌发具有显著促进作用,芽孢杆菌和腐殖酸处理也表现出较好的促萌效果。栽培阶段各因素对种球生长的影响程度由大到小依次为生物制剂、施肥策略、物理调控,其中生物制剂处理可显著提高种球平均直径和围径,高钾肥处理有利于促进种球膨大。综合分析表明,以温度调控为主导的促萌处理与以生物制剂和施肥管理为核心的栽培调控相结合的分阶段协同管理模式,可显著提高百合种球生长质量。即定植前预处理采用15 ℃处理6 d后转入5 ℃处理28 d的分段变温处理,并配合200 mg/L NAA溶液浸泡20 min可高效促萌;栽培期结合摘蕾管理并施用高钾肥和腐殖酸,可有效促进种球膨大与生长。

Abstract: To identify key regulatory techniques for the rejuvenation of degenerated lily (Lilium spp.) bulbs, degenerated lily bulbs were used as experimental materials. An orthogonal experimental design was employed to systematically investigate the effects of temperature regulation, plant growth regulators, and biological agents on bulb sprouting and subsequent growth, screening key technical combinations for promoting bulb rejuvenation from two stages (pre-sprouting treatment and cultivation management). The results showed that, during the pre-sprouting stage, the effects of the tested factors on bulb sprouting rate followed the decreasing order of temperature regime > plant growth regulator > biological agent. An appropriate variable-temperature treatment significantly increased the sprouting rate, treatment with 200 mg/L NAA markedly promoted sprouting, and treatments with Bacillus spp. and humic acid also showed good effects on sprouting. During the cultivation stage, the effects of the tested factors on bulb growth followed the decreasing order of biological agent > fertilization strategy > physical regulation. Biological agent treatments significantly increased the mean bulb diameter and circumference, while high-potassium fertilizer was beneficial for bulb enlargement. Comprehensive analysis indicated that a staged and synergistic management strategy combining temperature-dominated pre-sprouting treatment with cultivation regulation centered on biological agents and fertilization management significantly improved the growth quality of lily bulbs. Specifically, pre-planting treatment with 15 ℃ for 6 d followed by 5 ℃ for 28 d, combined with soaking in 200 mg/L NAA solution for 20 min, effectively promoted sprouting. During cultivation, bud removal combined with the application of high-potassium fertilizer and humic acid effectively promoted bulb enlargement and growth.
