Study on Construction and Major Management Technology of Seed Production Base for Pinus Massoniana Lamb var.Yichangensis Huang et Zhuang

摘要:

宜昌薄皮马尾松(Pinus massoniana Lamb．zlar．yichangensis Huanget Zhuang)是经中国林科院树木分类学家洪涛教授定名的1个新变种，该变种具有树皮薄、生长快、干形好、材质优良、出材率高、林分生物量及光能利用率高、适应性广等特点。本文从宜昌薄皮马尾松分布区域及资源状况的确定、采种基地的工程建设程序、建设过程及成绩、基地建设的主要经营技术、采种基地建设成功的初步经验等方面进行了全面总结。为今后我省其他采种基地的建设提供了方法和技术。

Abstract:

Pinus massoniana Lamb. var. Yichangensis Huang et Zhuang is one new variety denominated by tree taxonomist Prof. Hong Tao from China Academy of Forestry and with many specialties such as thin bark, fast-growing, excellent stem quality, high forest stand biomass, high utilization percent of light energy and wide adaptability. This article carries on an overall summary from aspects of determination in distribution and resource status of Pinus massoniana var. Yichangensis Huang et Zhuang, procedures for engineering construction of seed production base, construction process and achievement, major management technology and initial successful experience in construction of seed production base. It has provided technology and method for future construction of other seed production bases in our province.
