高、冠幅、根长和根重均产生极显著影响；五指毛桃地径和苗高长势最佳的是位于中坡的密度为 6 255 和
3 120 株 /hm2 的植物样本；冠幅长势最佳的是位于上坡和中坡的密度为 3 120 株 /hm2 的植物样本；地下

| Abstract: |
| In this paper, Ficus hirta was studied as an understory economic model, which was in Jiulianshan
forest farm of Guangdong Province. By using the two-way analysis of variance, through the three effects of slope
position, density and the interaction of slope position and density to study its effects on ground diameter, seedling
height, crown width, root length and root weight. The results showed that different slope positions had significant
effects on ground diameter, crown width, root length and root weight of F. hirta. Different densities had significant
effect on the ground diameter, crown width, root length and root weight of F. hirta. The interaction of different
slope positions and density had a very significant effect on the ground diameter, seedling height, crown width,
root length and root weight of F. hirta. The best ground diameter and seedling height of F. hirta were located onthe middle slope with density of 6 255 plants / hm2
and 3 120 plants / hm2
. The best crown width of F. hirta were
located on the upper and middle slopes with density of 3 120 plants / hm2
. The best underground growth of F. hirta
were located on the upper slope with density of 2 760 plants / hm2. |
