摘　　要：以油茶翠屏-15号良种为试材,研究嫁接方法(胚芽切接法、胚芽劈接法、胚根劈接法)、嫁接时间(3、5、9、12月)对油茶芽苗砧嫁接育苗成效的影响,结果表明:嫁接方法、嫁接时间是影响油茶芽苗砧嫁接育苗成效的关键因素,综合考虑苗木的成活率、地径和苗高,嫁接方法以胚芽劈接法最好,其嫁接口愈合好,平均成活率91.88%,苗木生长迅速,可当年出圃;嫁接时间以夏季5月最佳,平均成活率91.19%,苗木生长良好。Taking the improved variety of Camellia oleifera cuiping-15 as the test material, the effects of grafting methods(embryo cutting, embryo splitting and radicle splitting) and grafting time(March, May, September and December) on the seedling raising effect of Camellia oleifera bud seedling rootstock grafting were studied. The results showed that grafting methods and grafting time were the key factors affecting the seedling raising effect of Camellia oleifera bud seedling rootstock grafting. Considering the survival rate, ground diameter and seedling height of seedlings, embryo splitting grafting is the best grafting method, its marriage interface heals well, the average survival rate is 91.88%, and the seedlings grow rapidly and can be out of the nursery in the same year;the best grafting time was May in summer, the average survival rate was 91.19%, and the seedlings grew well.
