马尾松丰产林生长和技术经济效果评价

Growth of High-yield Forest of Pinus massoniana and Evaluation of Technical and Economic Efficiency

结合福建省世行造林项目，选择在闽中地区尤溪县，采用裂区区组设计，探讨不同种源不同密度马尾 松丰产林的生长和技术经济效果，结果表明，广西容县马尾松种源最为理想，密度以２８８０株／ｈｍ~２为宜。

Analysis was made on the growth of high-yield forests of Pinus massoniana on the different conditions of provenance and density. The results showed that,the provenance in Rongxian of Guangxi was best and 2880 plants per hectare was suitable density.
