Promoting bloom and preservation of cut branches of Forsythia suspensa were studied in this experiment,using aluminum sulfate,citric acid,calcium chloride and sucrose as raw material for the preparation of fresh keeping agent and treatment.The results showed that the flowering time of Forsythia suspensa was ahead of time in 3％ sucrose solution,with calcium chloride 1 g/L,citric acid 500 mg/L and aluminum sulfate 100 mg/L,the effect was eminent.%试验以硫酸铝、氯化钙、柠檬酸、蔗糖为原料配制的催花保鲜剂,对连翘切枝进行处理,就连翘切枝催花及保鲜的方法进行了研究.结果表明,在浓度为3％的蔗糖溶液作用下,以氯化钙1 g/L、柠檬酸500 mg/L、硫酸铝100 mg/L催花保鲜效果最为显著.
