In order to study the factors affecting the grafting survival rate and seedling growth of Camellia oleifera buds,three factors of scion variety (A),rooting powder concentration (B) and scion thickness (C) were selected,and each factor was set to three levels of L9 (34) orthogonal test design.The results showed that factor A had a great effect on the graft survival rate of Camellia oleifera;factor B was not the main factor affecting grafting survival rate,ground diameter and seedling height;factor C mainly affected the growth of seedling ground diameter and seedling height of Camellia oleifera.The optimal combination of three indexes of survival rate,ground diameter and seedling height,is A1 B3 C3.After grafting for 120 days,the graft survival rate was 92.22％,the diameter was 2.07 mm and the seedling height was 11.2 cm.%为探讨油茶芽砧嫁接成活率及苗木生长的影响因素,选取接穗品种(A)、生根粉浓度(B)和接穗粗度(C)3个因素,每个因素分别设3个水平进行L9(34)正交试验设计.结果表明,因素A对油茶嫁接成活率影响较大;因素B不是影响嫁接成活、地径和苗高生长的主要因素;因素C主要影响油茶苗木嫁接后期地径和苗高的生长.影响油茶芽砧嫁接成活率、地径、苗高3个指标的最优组合是A1B3C3.嫁接120 d后,嫁接成活率达92.22％,地径2.07 mm,苗高11.2 cm.
