摘　　要：金雀花是传统的食用花卉,为提早金雀花的花期以满足市场需求,以3年生植株为材料,研究了不同时间覆膜、不同增温栽培环境和不同浓度赤霉素对金雀花花期的影响。结果表明:金雀花在落叶休眠后覆膜,对促花效果更好,比不落叶覆膜开花早20 d;日平均温度越高,开花越早,习光温室+内保温膜栽培环境下开花最早,现蕾期、始花期比露天生长分别早29 d、26 d;喷洒赤霉素450 mg/L时的始花期比喷洒清水处理要早4 d。促成栽培措施对单株花量的影响并不明显。Caragana sini ca is a kind of traditional edible flower,aim to advance blooming for its market demand,taking 3 years old plants as test materials,this paper explored the effects of forcing culture on flowering time in terms of different building plastic shed times,different temperatures,dif-ferent concentrations of gibberellins.The results showed that the flowering time could be advanced when plastic shed was built after deciduous dormancy,which was 20 days earlier than plastic shed was built before dormancy.The higher daily mean temperature,the earlier the florescence was.When plan-ted in solar greenhouse with heat preservation film,the blooming time was the first;the budding time was 29 days earlier and the first flowering time was 26 days earlier than that when planted in the open air.Under 450 mg.L gibberellins,the first flowering time was 4 days earlier than that under clean wa-ter.But the forcing culture had no obvious influence on flower numbers per plant.
