班克松(Pinus banksiana)又叫短叶松,是一种生长较快、寿命较短的北方松。它广泛分布于加拿大及美国北部,是美洲松中分布最北的一种。长春市净月潭林场大约于1948年曾引进过少量班克松种子,并且用这批种子育苗、造林,现尚有32株大树,并早已开花结实。林场于1966年将大树上采得的种子进行了育苗,并营造了小面积班克松纯林和班克松与樟子松的混交林。本文主要介绍我们对以上林地调查情况及树干解析后的情况分析。
Pinus banksiana (Pinus banksiana), also known as pine, is a growth faster, shorter life of the North pine. It is widely distributed in Canada and the northern United States, is the North American pine distribution of the most northern one. Jingyuetan Forest Farm in Changchun City introduced a small amount of Bancroft seeds in about 1948, and raised seedlings and afforestation plants with these seeds, and now there are 32 large trees that have long flowered. In 1966, the tree farm nursed the seed collected from the big tree and created a small-scale pure forest of Bancroft and mixed forest of Bancroft pine and Pinus sylvestris. This article mainly introduces our analysis of the situation of the woodland above and the analysis of trunk after the above analysis.
