摘　　要：“海之星”免疫增强型壳寡糖生物制剂是中国科学院”糖链植物疫苗”技术成果转化研究中以壳寡糖为主要原料经过多种对低温抗性有效的成份复配成的对低温冷害有很好效果的水溶性制剂。该研究通过现场实地操作,得出试验数据证明,规律地喷施750倍的”海之星”免疫增强型壳寡糖制剂能够有效地恢复低温冷害对红花檵木造成的损伤,并能提高红花檵木的免疫机能,促进恢复后期叶片增大,叶片颜色变深,促进花芽分花量,可为壳寡糖在红花檵木冻害后的恢复防治应用中提供依据。同时也为将“海之星”免疫增强型壳寡糖生物制剂推广至园林植物冻害后的修复与救治中提供可能。“Haizhixing”immunity-enhancing chitooligosaccharide biological preparation is a water-soluble preparation with a good effect on chilling injury,which is prepared with chitooligosaccharides as the main raw material and a variety of effective ingredients for low-temperature resistance in the research on the transformation of technical achievements of“carbohydrate-based plant disease vaccine”by the Chinese Academy of Sciences.Through field operation,the experimental data obtained in this study proved that regular spraying of“Haizhixing”immunity-enhancing chitooligosaccharide preparation at 750 times could effectively recover the damage to Loropetalum chinense var.Rubrum caused by chilling injury,improve the immune function of Loropetalum chinense var.Rubrum,and promote leaf growth,leaf color deepening and flower-bud differentiation in late recovery.This study can provide a basis for the application of chitooligosaccharides in the recovery and prevention of Loropetalum chinense var.Rubrum after freezing injury,and also a possibility for the promotion of“Haizhixing”immunity-enhancing chitooligosaccharide preparation to the restoration and treatment of garden plants after freezing injury.
