Detail
洋桔梗的生长适温为15~28℃,生长期夜间温度不低于12℃。冬季温度在5℃以下,叶丛呈莲座状,不能开花。也能短期耐0℃低温。生长期温度超过30℃,花期明显缩短。

洋桔梗对水分的要求比较严格。洋桔梗虽然喜欢湿润环境,但过量的水分对洋桔梗根部生长不利,易受病害侵入。花蕾形成后要避免高温高湿环境,否则容易引起真菌性病害。同时,生长期供水不足,茎叶生长细弱,并提早开花。因此,在以色列栽培洋桔梗,采用滴灌设施,对洋桔梗的生长发育十分有利。

洋桔梗对光照的反应比较敏感。长日照对洋桔梗的生长发育均十分有利,有助于茎叶生长和花芽形成,一般以每天16小时光照效果最好。

洋桔梗要求肥沃、疏松和排水良好的土壤。切忌连作。盆栽用土必须消毒,可用高温蒸汽或溴化甲醇处理土壤,土壤出以6.5~7.0为宜。
