火炬松优良家系纸浆材林定向培育技术研究

The directional breeding technology for Pinus taeda L. fine family paper pulp forest

通过对火炬松优良家系纸浆材示范林、试验林(包括苗木试验、密度控制、整地试验、抚育试验、施肥试验、修枝试验等)及相关资料进行系统分析研究,提出了由优良家系苗木的选择应用技术,立地与气候等主要生境选择应用技术,以及丰产栽培技术措施组成的火炬松优良家系纸浆材林定向培育技术。

Based on the systemic analysis of demonstration forest and testing forest of Pinus taeda L.fine family as following: testing on seedlings,controlling the density,experiments on soil improvement, breeding, fertilizer and pruning.The directional breeding technology for Pinus taeda L.fine family paper pulp forest were pointed out as three technologies: the choosing application technology of fine family seedling, the choosing application technology of main growth environment with soil stand and climate, and highyield planting technology.
