| 摘要: |
| 选用厚荚相思(Acacia crassicarpa)、台湾相思(Acacia confusa)和小叶榕(Ficus microcarpa)3个树种在崇左市石山地区进行造林试验,3年后调查分析造林绿化效果。结果表明,树高、地径和冠幅的净生长量,厚荚相思分别达到4.4m、7.1cm和2.8m,分别为台湾相思的2.0倍、2.4倍和1.6倍,为小叶榕的6.3倍、2.6倍和3.1倍。厚荚相思的石山造林绿化效果极显著地优于台湾相思和小叶榕。而且厚荚相思林下植被总盖度、枯落物等生态环境比后两种优良。厚荚相思是崇左市石山地区人工造林绿化的优良先锋树种。 |

| Abstract: |
| Silviculture experiments of three selected species including Acacia crassicarpa,Acacia confusa and Ficus microcapa are carried out on Karstic hills in Chongzuo city.Three years after the experiments,a survey is conducted on the greening effect.The results shows that Acacia crassicarpa produces quite significant effect on net increment in terms of height,ground diameter and crown,which are 4.4 m,7.1 cm and 2.8 m respectively,2.0 times,2.4 times and 1.6 times of that in Acacia confusa,and 6.3 times,2.6 times and 3.1 times of that in Ficus microcapa.Acacia crassicarpa cultivation produces better greening effect than Acacia confusa and Ficus microcapa.And the ecological environment,such as total vegetation coverage and litter layer in Acacia crassicarpa sites is much better than that in the other two species.Acacia crassicarpa is considered pioneer species for afforestation on Karstic hills in Chongzuo city. |
