摘　　要：以在黑龙江省森林植物园开展的寒葱播种试验为基础,从不同播种时间、不同层积方式和不同成熟度种子繁殖育苗,观测不同处理对出苗时间、出苗率、株高和叶宽的影响。结果表明,播种时间在7月份;GA3-100浸种24 h;层积温度-3℃~4℃均有利于提高种子出苗率;种子出苗率与种子成熟度呈相同趋势;寒葱株高和叶宽与出苗时间呈正比。Based on the seeding experiments of Allium victorialis in Heilongjiang Forest Botanical Garden,the seeds with different sowing time,different stratification mode and different maturity were planted.The effects of different treatments on seedling emergence time,seedling rate,plant height and leaf width were observed.The effects of various treatments on seed seedling were summarized,and it can provide technical supports for large-scale artificial cultivation of Allium victorialis.
