| 摘 要： | 对广西钦州市北区平吉紫胶林场尾巨桉( DH32 - 29)和尾叶桉(U6)人工林一代林与二代林(第一代萌芽林)蓄积生长情况进行对比分析,得出尾巨桉(U6)第二代林木单位面积年均蓄积生长明显低于一代林木,在相同立地条件下,对地力衰退影响也较大；而尾巨桉( DH32 - 29)第二代林木单位面积年均蓄积量与第一代林基本持平.说明尾巨桉人工林更适合在试验区进一步推广. |
| 关 键 词： | 尾巨桉 尾叶桉 蓄积生长量 |

| Abstract: | By comparing and analyzing the volume increment per unit area per year of the Eucalyptus （DH32-29 and U6） plantations between theirs first and second generation forest at Guangxi Qinzhou city Qinbei District Ping Ji lac forest farm. The results show that： annual forest growth and accumulation of second-generation Eucalyptus grandis （U6） trees per unit area was significantly lower than the first generation, in the same site conditions, impact on soil degradation was greater as well; while average annual forest stock volume of second-generation Eucalyptus grandis （DH32-29） forest per unit area was essentially flat with the first generation. It is illustrated that Eucalyptus grandis plantation is more suitable for further promotion in the test area. |
