摘　　要：【目的】探明“岑软24”等6个油茶无性系新品种在广西三江侗族自治县幼林期的生长表现,为该地新造油茶林提供依据。【方法】造林3个月后统计造林成活率,2022年12月测定试验林植株树高、地径、冠幅3个指标,并统计2年生开花株数,采用单因素方差分析和沃勒-邓肯法比较数据间的差异。【结果】参试6个无性系造林成活率都在92.0%以上,均达到当地栽植成活标准;造林2年,6个无性系树高、地径、冠幅、开花株数比例存在显著差异。树高表现最优为“岑软11”,其后依次为“湘林210”“岑软24”“岑软3”“华硕”“桂普32”;地径表现最优为“岑软11”,其次为“岑软24”;冠幅表现最优为“岑软24”,其次为“湘林210”;开花株数比例值表现最大的是“岑软24”,其次是“华硕”。综合表现“岑软11”“岑软24”“湘林210”在造林前期表现出较大生长量,综合表现好。【结论】建议油茶新造林通过合理选择无性系、科学配置无性系以获得较高产量。【Objective】To find out the growth performance of six new clones of Camellia oleifera,such as“Cenruan No.24”,in the early stages of afforestation in Sanjiang Dong Autonomous County,Guangxi,and provide a basis for the new Camellia oleifera forest in this area.【Method】The survival rate was counted after 3 months of afforestation.In December 2022,the tree height,ground diameter,crown width of the test forest were measured,and the survival rate and 2-year-old flowering tree after 3 months of afforestation were counted.One-way analysis of variance and Waller-Duncan method were applied to compare the differences between the data.【Result】The results showed that the afforestation survival rates of the six clones tested were all above 92.0%,meeting the local planting survival standards;After 2 years of afforestation,there were significant differences in the ratio of tree height,ground diameter,crown width,and flowering plants among the six clones.The best tree height performance is“Cenruan No.11”,followed by“Xianglin No.210”,“Cenruan No.24”,“Cenruan No.3”,“Huashuo”,and“Guipu No.32”.The best ground diameter performance is“Cenruan No.11”,followed by“Cenruan No.24”.The best crown diameter performance was“Cenruan No.24”,followed by“Xianglin No.210”.“Cenruan No.24”showed the highest percentage of flowering plants,followed by“Huashuo”.Overall,“Cenruan No.11”,“Cenruan No.24”,and“Xianglin No.210”showed significant growth in the early stages of afforestation.【Conclusion】It is suggested that the new afforestation of Camellia oleifera should obtain higher yield by reasonable selection of clones and scientific allocation of clones.
