摘要
以从湖南省引进的13个油茶(Camellia oleifera)良种为研究材料,开展引种栽培试验,通过造林成活率、保存率、树高及地径4个性状指标的观测,分析引进油茶良种适应性。结果表明,不同油茶良种的造林成活率、保存率及幼林的树高、地径均存在显著或极显著差异。基于造林的保存率及聚类分析的结果,可优先选择造林保存率高且生长快的湘林32、湘林78、湘林97和湘林210等4个良种作为富宁县油茶产业发展引进推广的良种,其2年生幼林的树高、地径的生长量分别可提高14.3%~22.9%、9.3%~20.4%,分别达80.00~86.00cm、78.67~86.67mm;其次是湘林1、湘林3、湘林4和湘林27。
The introduction and cultivation test was carried out by using 13 improved varieties of Camellia oleifera introduced from Hunan province as research materials. The adaptability of varieties was analyzed through observation of afforestation survival rate,preserving rate,tree height and ground diameter. Results showed that there were significant or extremely significant differences in survival rate,preserving rate,tree height and ground diameter of young C. oleifera cultivars. Based on results of afforestation preservation and cluster analysis,four cultivars Xianglin 32,Xianglin 78,Xianglin 97 and Xianglin 210 with high preserving rate and fast growth rate were chosen as improved varieties for development of C. oleifera industry in Funing county. The tree height and ground diameter of these two-year-old young forests could increase by 14.3% to 22.9% and 9.3% to 20.4%, reaching 80.00~86.00 cm and 78.67~86.67 mm, respectively. Followed by Xianglin 1,Xianglin 3,Xianglin 4 and Xianglin 27.
