马尾松天然林优树选择采用5株优势木选择法,用差异显著性分析的数学统计方法,以尽可能剔除因环境影响而造成差异的个体,选择在数量生长的遗传性状上更为优良的个体。根据速生丰产的选择目标,实测并计算与候选优良个体形质指标和生殖生长最为密切的胸高形率、弯曲度、树皮指数和结实指数,进行量化比较,得分在30或30以上的个体,可作为优树正式入选。
Masson pine natural forest selection of trees by five dominant wood selection method, the use of significant difference between the mathematical statistical methods to eliminate as much as possible differences caused by environmental impact of individual selection in the quantitative growth of genetic traits more excellent individual. According to the selection target of fast-growing and high-yielding, we measured and calculated the thorax-height ratio, tortuosity, bark index and fruiting index, which were most closely related to the elite candidate phenotype and reproductive growth, Can be selected as excellent trees.
