以吉林地区习见的大黄柳(Salix raddeana Laksch.)和细柱柳(Salix gracilistyla Miq.)花序枝为材料,通过染色技术进行艺术加工,研制符合大众审美需求并适宜长期观赏的干花。目前,尚未见有相关报道。实验对花序枝最佳采收时期、染色浓度、染色时间等制作工艺进行了对比研究。结果表明,最佳的采收时间为3月末4月初花序刚长出不久,大黄柳、细柱柳的最佳采收长度分别为0.5~2.0cm、0.5~1.5cm,此时牢固度最好。最佳的食用色素染色浓度为4.5%~7.5%,染色时间为1~10min,可根据颜色需求在此范围内进行浓度或时间的调整。
In this paper, the flowers of Salix raddeana Laksch. And Salix gracilistyla Miq. In Jilin Province are used as materials to process the art by dyeing technique to produce dried flowers suitable for aesthetic appreciation of the public and suitable for long-term ornamentation. At present, there is no relevant report yet. Experiments on the best time to collect inflorescences, dyeing concentration, dyeing time and other production processes were compared. The results showed that the best harvesting time was at the beginning of March and the beginning of April, the inflorescence just grow up shortly after harvest, the best harvesting lengths were 0.5 ~ 2.0cm, 0.5 ~ 1.5cm, the best firmness . The best food coloring dye concentration of 4.5% to 7.5%, dyeing time is 1 ~ 10min, according to the color needs in this range concentration or time adjustment.
