不同马尾松良种在闽北栽培效果初步研究

Preliminary study on the growth effects of different improved variety of Pinus massoniana in northern Fujian

2000-2005年,每年春季分别在闽北7个国有林场用广西马尾松种子园和福建漳平五一国有林场马尾松种子园的种子育苗、造林,通过2005年的调查数据分析结果表明：广西马尾松良种在同一地点,树高、地径生长好于漳平马尾松良种,冠幅生长性状基本相等;广西马尾松良种在南平樟湖国有林场栽培效果最佳,漳平马尾松良种在浦城大庄国有林场栽培效果最佳,本地马尾松以建瓯水西国有林场生长最佳,广西马尾松良种更适合于纬度较低、积温较高的地区发展。

In every spring from 2000 to 2005, in every spring the seeds from Guangxi Seed Orchard and Wuyi National Forest Farm of Zhangping Fujian were used for raising seedlings and afforestation. The analysis of investigation data in 2005 showed the tree height and ground diameter growth of Pinus massoniana from Guangxi were better than that from Zhangping in the same site, but nearly the same in crown diameter; Pinus massoniana from Guangxi behaved best in Zhanghu National Forest Farm of Nanping; Pinus massoniana from Zhangping behaved best in Dazhuang National Forest Farm of Pucheng; Native Pinus massoniana behaved best in Shuixi National Forest Farm of Jian＇ ou; Pinus massoniana from Guangxi behaved better in lower latitude and higher accumulated temperature area.
