用15个月龄云南红豆杉（Taxus yunnanensis）实生苗，通过3.5 a不同造林密度试验观测苗高、地径、侧枝数量，分析了造林密度对云南红豆杉幼林生长和经济效益的影响。结果表明：不同造林密度对云南红豆杉幼林树高、地径和侧枝数量以及生物量等各个方面均有显著影响，地径随着密度减小而增大，林分生物量随密度增大而减小；采用茶园式模式造林，云南红豆杉宜采用的为造林密度0.75 m×0.75 m。

Plantation of 15-month Taxus yunnanensis seedling was implemented with different density. 3.5 years later, seedling height, ground diameter and numbers of lateral branches were determined. The results showed that various plantation densities had significant effect on height, ground diameter growth and number of lateral branches of seedlings. Ground diameter increased with the decreases of density. Stand biomass decreased with increasing of the density. The experiment demonstrated that the optimal density for plantation ofT. yunnanensis was 0.75m × 0.75m.
