摘　　要：对柏木（Cupressus funebris）不同无性系、母树年龄、插穗类型、扦插基质和插穗处理等5 个因素扦插育苗试验的研究结果表明,不同无性系的扦插成苗率差异极其显著,变幅15% - 100%;利用6 年生以下母树上的穗条扦插都可获得较高成苗率,但随着采穗母树年龄的递增其扦插成苗率和苗木质量会有明显降低;ABT1 促根处理对柏木嫩枝扦插成苗率和生根数等性状无显著影响,但对扦插苗的高生长有明显促进作用;柏木嫩枝扦插一般在6 月上旬进行,选用3 - 6 年生优良无性系或优良单株上生长旺盛的当年生嫩梢采穗,并按要求扦插,大规模扦插成苗率可达75%以上一年生移栽苗苗高、地径和一级分枝数可分别达30.00 cm、3.00 mm 和15.0 支左右.Experiments were conducted on seedling cultivation of Cupressus funebris by cuttings with different clones, mother tree age, cutting types,substrate and treatment of cuttings. The results showed that survival rate of different clones ranged from 15% to 100%. Favoring survival rate couldbe obtained in cuttings from mother tree less than 6-year, negative correlation between cutting age and survival rate was observed. Survival rate wasnot significantly improved by ABT treatment, whereas seedling height was largely increased by ABT. It was suggested that cuttage of cypress shouldbe performed in the early June, with softwood cuttings on 3-6- year plus clones or trees. With the cuttage techniques above-described, the survivalrate could be reached above 75% in large-scale cutting propagation, whereas seedling height and diameter could reach 30 cm and 0.3 cm respectively.
