A cinnamomun camphcra seedling growing method comprises the steps that high-quality cinnamomun camphcra seeds are selected as raw materials, a benzalkonium bromide solution is used for soaking cinnamomun camphcra seeds, the cinnamomun camphcra seeds are placed into deionized water with the water temperature being 55-60 DEG C to be soaked for 36-48 h, after soaking is completed, the seeds are placed into a germination acceleration room for bud forcing treatment for 5-8 d, the temperature is kept to be 40-50 DEG C in the germination acceleration process, the soil covering thickness is 3-5 cm during seed sowing, water is sprayed during seed sowing, the water yield is 20-30 ml on per seed, the seeds need to be covered with straw in time after seed sowing, the cinnamomun camphcra seeds obtained after germination acceleration germinate 25-35 days after seed sowing, after seed germination, the cover is removed in time, and damage caused by the straw to buds is avoided. By adding nutrients of different contents, on the basis that nutrients needed by cinnamomun camphcra growth is ensured, nursery stock growth is promoted, the seedling growing time limit is shortened, growth is rapider, the survival rate is increased, and the planting effect is improved.
