| 为了解不同产地选育的油茶 Camellia oleifera 苗在广东省肇庆市广宁县江屯镇的生长适应性 ,
选取来自湖南、江西、广西和广东共 18 个品种的油茶为试验材料，并于栽种 2 年后调查其成活率、病
虫害发生率、生长量、开花及树型等情况。结果表明：参试油茶品种中苗木较大（苗木大小为苗高 ×
冠幅），开花数量较多的是岑软 2 号、岑软 3 号、赣州油 1 号、赣石 83-4、华鑫、长林 4 号及华硕。其
中 , 岑软 3 号和赣州油 1 号移栽后成活率最高，为 100%。而华金、赣无 2 和湘林 1 号生长较弱，分别为
83.3%、90% 及 86.7%，更易发生病虫害。 |

| Abstract: |
| To understand the growth adaptability of Camellia oleifera seedlings selected from different producing areas in Jiangtun town, Guangning county, Zhaoqing city, Guangdong province. A total of 18 varieties of C. oleifera from Hunan, Jiangxi, Guangxi, and Guangdong were selected as the experiment materials.The survival rate, incidence of pests and diseases, growth, flowering, tree architecture of C. oleifera were investigated after 2 years of planting. The results showed that among the cultivars, the seedling body size （seedling height×crown width）with more flowers was Cenruan No.2, followed by Cenruan No.3, Ganzhouyou No.1, Ganshi 83-4, Huaxin, Changlin No.4 and Huashuo. Compared with other varieties, Cenruan No.3 and
Ganzhouyou No.1 had the highest survival rate after transplanting, and all the seedlings survived, while Huajin, Ganwu 2, and Xianglin No.1 grew weaker, with a survival rate of 83.3%, 90.0%, and 86.7%, respectively, and were more prone to pests and diseases. |
