摘　　要：对山苍子种子贮藏、种子育苗、扦插、嫁接等进行了为期3年的研究,结果表明:山苍子种子贮藏以沙藏为好,春季育苗发芽率达46.4%;山苍子种子催芽采用80℃的热水浸种,可提高发芽率和发芽势;与春播相比,秋播种子发芽率、发芽势相对较低,但无论是苗高、地径还是冠幅都更大;无论是春播或者秋播,浸种催芽的比无浸种催芽的发芽率或发芽势都更高,而且生长量也更大;扦插用吲哚丁酸100 mg.kg-1+萘乙酸50 mg.kg-1溶液浸泡60 m in成活率最高;嫁接以T字形芽接成活率最高。Three years researches were conducted on the seed storage and grow seedlings of Litsea cubeba, the results were as follows： Litsea cubeba seed storage of sand was the best, seedling germination rate was 46.4% in spring; Litsea cubeba seed soaked in 80 ℃ hot water, could increase the germination rate and germination potential; compared to spring sowing, the seed germination rate and germination potential of autumn sowing were relatively low, but both the height, diameter or the crown were greater; either spring or autumn sowing, both germination rate or germination potential by soaking expedite-budding were higher than that by non-soaking, the growth amount was bigger by the above;cuttage by using 100 mg ·kg-1 IBA ＋50 mg NAA/kg for 60 minutes long soaking had highest survival rate; the survival rate of graft was the highest with T shaped budding.
