| 摘要: |
| 四种南洋杉科树种引种至开平市林场，6年生林分生长结果显示：肯氏南洋杉适应性强，保存率高，生长较快，是表现最好树种；其次是贝壳杉，能适应当地条件，保存率高，生长较好；这两者在低山丘陵栽培有较大发展潜力。阔叶南洋杉不大适应当地条件，生长慢，保存率不高，不适宜在低山丘陵种植，但树形美观、枝叶茂盛作为园林绿化树种则很有潜力。亨氏南洋杉不能适应当地立地和气候，生长差保存率低（仅保存33.7%），不宜种植和发展。 |

| Abstract: |
| four Araucaria tree species including Agathis dammara Rich., Araocaria bidwilli Hook. , A. cunnighamii and Araucana hensteinii was intrudced in kaiping city, guangdong province. The results shows that Araucaria cunninghamii have high adaptability and best growth performance. Agathis dammara is also adapt to local conditions, both are suitable for low hills and cultivated in largescale. Araocaria bidwilli not suited to local conditions , But the tree branches, luxuriant appearance as landscaping tree is a potential. Araucana hensteinii can not adapt to the local climate, poor site and grow only save 33.7 percent lower (decreasing), unfavorable planting and development.
both cultivation in hilly greater potential for development. Araocaria bidwilli not adapted to local conditions,
