摘　　要：为明确压条角度对闽楠快速繁殖中新穗条生长的影响,设置4个压条角度(0°、45°、90°、135°),分析不同压条角度对春季和夏季闽楠压条存活率、新穗条数量及生长量的影响。结果表明,高角度压条(90°、135°)在春季和夏季压条均具有较高的存活率;新穗条数量虽未随压条角度发生显著变化,但春季的新穗条数量明显高于夏季;低角度压条(0°、45°)下新穗条生长量较大,且夏季新穗条生长量高于春季。To clarify the impact of layering angle on the growth of new shoots in the fast reproduction of Phoebe bournei,this study set up four layering angles(0°,45°,90°,and 135°)and analyzed their effects on the survival rate,number,and height growth of new shoots during spring and summer seasons.The results showed that higher angles(90°and 135°)exhibited significantly higher survival rates in both seasons.Although the number of new shoots was not significantly affected by the layering angles,the spring season produced significantly more shoots than summer.Lower angles(0°and 45°)resulted in taller new shoots,with summer shoots being taller than those in spring.
