摘要
云南松是云贵高原的主要用材树种,在林业生产上占有重要的地位。本文以云南松分布区生态条件差异的研究为依据,在总结过去生产经验及参考种源试验初步成果的基础上,划分出六个种子区,从而为今后用种及种子调拔提供依据。
Pinus yunnanensis, which is a main commercial species in the YunnanGuizhou plateau, holds an important position in forestry production. Based upon the study on the differences of the ecological condition in the distribution range of Pinus yunnanensis, this paper suggests 6 divided seed areas so that it provides a scientifie base for the future use and allocation of the seeds by means of summing up the experience of past production and referring to the experimental results of the seed source.
